Pass Microsoft Azure AZ-104 Exam in First Attempt Easily

Microsoft Azure Administrator Certification Course

1. Azure Free Account

I don't believe that you can pass without any hands-on experience. And for that, you're going to need an Azure account. Now, Azure does provide a free account with some limited privileges. If you need one to pass, or if you already have access to an Azure account through yourself or some other means, then you can use that account. If you do already have an account set up and ready to go, you can skip the rest of this video and move on to the next section. The rest of this video is going to be talking about the free account, the limitations on that, and how to get one. Now go to your favorite search engine, if it's Google. I enter the word "Azure" and hit Enter.

Now this link that comes up is the Microsoft website, Azure (microsoft.com/country free). If I click on it, you can see the advertisement for the Azure free account. Now, scrolling down a little, we can look at the limitations, because it's critical to know when those expiry dates are while studying. Now, Microsoft does things a little differently than AWS. You get 30 days of free usage of Azure with a $2 credit. Now if you use up that $200 within the next 30 days, then you're going to have your system shut off. Or when the 30 days runs out and you haven't used your credit, you're going to basically lose that credit.

And on top of that, there are twelve months of services included in the free account. And these services switch over to paid services after twelve months. And there are also always free services. Scrolling down a little bit more, we can look at the different services that are available. So outside of the 200 credits in the first 30 days, you can also get up to two virtual machines. of a small size for up to twelve months. So you can still continue to practice even after the 30 days are over. You get some disc space, some Blob storage, file storage, etc.

Scroll back top and we're going to say start free. Now, in order to access Azure, you do need a Microsoft account. I can use this as the account I already have for Azure, but I can't get a second free account. Once you've used it, you can't have it again. So I'm going to say, use another account. Now, if you have another Microsoft-valid email address like Hotmail, Outlook, or something else, you can certainly use that one. Or if you don't have one and you want to use a different address, it says "Create one." And you can say "Create an account." You can provide your current email address, whether it's your personal or work address, or you can even create a new one. So let's say we got past creating an account" aspect. Now, to create an Azure account, you do need to provide some information.

You need to provide your name and phone number. You need to prove your identification by phone. You are also going to have to provide a credit card as validation and sign the agreement. Now, Microsoft does promise that there will be no automatic charges at the end of the 30 days. But your services will shut off if you use up your credit or if your 30-day trial has expired. And they're not going to start magically billing your credit card. But you do need a credit card in order to create an account. Part of the reason for this is so that they can restrict you to a single account per person, so you can't create a limited number of free accounts. Now, I should mention that you are a student studying at an accredited school. You can get a free Azure account. It does not require a credit card. Now, the number of credits you get, $100, is for a regular free account. And some of the free things that are included are a little bit less like your Linux virtual machine, but you won't get a Windows virtual machine, et cetera. So go to Microsoft.com Free students can get themselves a student account, with a credit card required if they qualify.

Once you've signed up for Azure, you're going to want to log into the Portal. Now the central URL for the Azure portal is portal azure?

That is where you're going to go every time you want to log into Azure and do something with it. Once you're logged in, you're going to see a home page similar to this. You're going to have some very frequent services across the top and some other options, including documentation and learning resources, along the bottom. We're going to get into all of these later in this course. Yeah, but for now, if you're able to get this far, then congratulations. You've successfully created your account.

2. Setting a Budget

So now that you've been able to log in or create an Azure Portal account, let's talk about some facts. When learning Azure for the first time, almost everyone wants to avoid any unexpected or surprise costs. Now, if you have an Azure free account, then you don't really have anything to worry about because Azure is giving you some free credits. The resources will then be shut down at the end of the free credits, and you will have to choose whether to go into a pay as you go plan.

Otherwise, you can't continue to use Azure. Now after the 30 days and you make the choice, you will have as you go plan, pretty much. How do you know? Now we're locked into the portal, and we're on the home screen. You can see the home screen underneath this hamburger menu here. And I'm going to click on Subscriptions, and we can see the subscription name. The default is Pay as You Go, but you can rename that to something that's more useful. If you've got multiple accounts, again, if it says free, then you don't have anything to worry about here.

But if it says "Page You Go," let's continue on. Now you can see that I've already incurred twenty-eight cents of costs this month. And that's not very much, obviously, but it is more than zero. We'd have to figure out what the $0.28 is for, where it's coming from, and whether we need to delete it or not. Now into the subscription. By clicking it, we can see that in the months of October and November, I accumulated $68 in costs. And I can almost guarantee you that what happened here was that I created some resources, then forgot about them, came back a couple of days later, and realized they were running. This is so common; it happens to pretty much everyone who's got a page you go plan.

Now what we're going to want to do is we're going to want to create a budget. So on the left side of the screen, under Cost Management, it says Budgets. Now by default, I don't have any budgets. What we're going to do is create our first budget. So we're going to say "add." Now we can say, "What is the scope of this budget?" Now we do want this first budget to affect our entire subscription. And so the default being the subscription is fine, but if we want to limit the budget scope to only a particular group or a particular resource, we can then navigate down into this resource group. And I can say this resource group here, I want to put the budget on there. But again, I'm pretty happy with the subscription level budget right now. We have to give you this new budget, and the names cannot contain spaces. Now, at what period do we want the budget to take effect? Maybe just the billing month, or the calendar month, or the quarter, etc., etc.

A month is just fine. Line budgets expire. And so this budget is good for another two years. Let's leave it like that. Now, it does look back upon me and make suggestions in terms of what would be a good budget. In this case, it's suggesting $8. Now, that's probably a little bit low, but let's say I really do want to be notified when the spending hits 20. That would be a significant number for me. So I'm going to put a number in there. Now, you might want this to say one, right? The budget could very well be any cost you want to be notified of. In this case, I'll let it go up to about $20. Now, keep in mind what's going to happen when this budget is hit.

Well, it's not necessarily what you expect. The budget doesn't stop running once it reaches the budget limit. It actually just alerts you. So we can give it a condition that says when 100 percent of the budget has been spent, which in my case is $20, I can just have it alert me by email. So I can enter my email address here and it will actually just send me an email when this budget is hit, and I can say "create." And so now at least I can get notifications when the budget hits $20 every month. This is very important to set up because I believe it's happened to almost everybody who's worked with Azure, where you accidentally start up a rep resource and you forget about it, and suddenly two days later, it has been spent.

Azure Concepts

1. *NEW* Overview of Azure VM and App Services

The first term is a virtual machine. Now, hopefully I've heard this before, but what exactly is it? It is either a Windows or a Linux operating system. It is a server that you can control. You can connect via desktop or SSH into it. It looks, acts, and behaves just like a real server, but the word "virtual" indicates that it's not actually an entire server that you are controlling; it is a server that's been virtualized, like a pizza that has been cut up into slices, and you only control one piece, but you wouldn't know that because it looks, acts, and behaves just like a full server.

Virtual machines must be on a virtual network, and they can be arranged in certain types of availability sets or put behind load balancers. You can physically distribute your virtual machines in a way that you've designed. Since you have full control over the virtual machine, that means you can remote into it using RDP or SSH, install software, change configurations, and so on.

You're also responsible for that operating system, so you have to keep the security patches installed and make sure scheduled updates and reboots happen, and stuff like that. Virtual machines can create it very quickly. Within four minutes, you can have a VM running so you can have an idea of 200 in the afternoon. By 250, you'll be remote desk toping into that virtual machine and starting to work on your idea. Now, like I said, a virtual machine is a foundation on top of which other compute services provide services.

So when you get a cottage container, you're actually working with virtual machines under the hood. Kubernetes is just an abstraction, and it's an orchestration layer on top with virtual machine skill sets. It's essentially a way to have a load balancer into multiple virtual machines and auto scaling rules using all of the fundamentals of that as well as batch and service fabric. Now, a complete paradigm for a virtual machine is what's called an app service or a web app, right? So these are basically a platform and a service. Now, you do get your choice of Windows or Linux as well, but you're not controlling those operating systems. So you can choose the Windows OS, but you don't get a say in terms of exactly what version of Windows is used, when security patches are applied, et cetera. fully managed servers, and you don't have remote access to them.

As fully managed servers, we now have access to the applications that can be installed on them, and Microsoft provides a few core programming languages such as.net languages Java, Ruby, and PHP in which you can write your code and install as app services. These are known as developer-friendly friendly service. So basically, it integrates into Visual Studio with one click Publish, continuous integration is available, and it has integrations with GitHub. You can use things like deployment slots and lots of different benefits as app services above a virtual machine, not to mention the fact that you're not managing the hardware or the operating system underneath it.

2. *NEW* Overview of Azure Storage and Data Services

To the Azure Storage category. You know, storage accounts can be quite large. You can have up to five petabytes in a single storage account, and of course you can create multiple storage accounts. Storage accounts don't cost you anything to create. They charge you based on the number of gigabytes that you're storing. So currently, it's 1.8 cents per gigabyte.

So if you were to try to fill one up to get those five petabytes in terms of storage, you're going to have quite the bill every month, something like $5,000 a month if you can fill up a single storage account per month. Now, files that are stored in a storage counter are actually broken up into blobs, queues, tables, and files, and they have different storage structures. Blobs are the most common, and you would use containers within Blobs to store your files.

It also comes with a title application. So at the most basic level for locally redundant storage, when you place your files in a storage account, Microsoft is keeping three copies of that file behind the scenes. So if any hardware fails, a data centre fails, or some type of catastrophe happens, Microsoft would have two additional copies of your files and you would not lose your files. It's extremely rare. I think there are eleven nines of durability for locally redundant storage and 16 nines of durability for glueing redundant storage.

You get your choice of storage tiers, which allows you to determine whether you want to save money on the storage fees or save money on access costs depending on your usage. There might be some ways of saving money, depending on the storage tier. And storage is an unmanaged thing by default. If you're creating machine disks, you might want to look at the managed storage, which is a fraction above this and is also charged differently. It's not charged per gigabyte, but it's better at dealing with virtual machines because it's optimised for randomised access. Now, storage is not the only thing that Azure supports. There's also data storage in terms of databases. Now you can basically broadly separate out the data storage types in terms of whether they're based on the SQL Server engine or they're not. If you're looking for databases that are based on SQL Engine, you've got SQL Server running on a virtual machine.

That is probably the closest thing that you get when you're migrating from your on-premises environment into Azure. You can migrate to an Azure SQL database. It still runs on the SQL Server Engine, but it's not 100% compatible. A SQL instance is sort of in between having a SQL Server on a virtual machine and having SQL. It is a managed instance of a real SQL Server, so it has quite good compatibility, but it's managed by Azure.

And finally, you can look at even things like a SQL Data Warehouse, which can be renamed Signups Analytics, where you're storing multiple petabytes of data and it's designed to be queried, not for transactions. You're looking at the non-SQL server side. You're looking at something like Cosmos DB as being the most prominent non-SQL server database that is a no-SQL database (non-relational database) and has data stored like MongoDB or in Document DB, which is a JSON or Graph API.

There are very different ways of storing your data with DB, which we'll get into in this course. You also have other mandatory like MySQL PostgreSQL Maria DB. Finally, Azure Cache isn't recognized as a data storage, but it is a data storage. You're using your application to store data temporarily for sessions or for temporary purposes. And so use Radis, which is an open source piece of software managed by Azure, to store silver.

3. *NEW* Overview of Azure Networking Services and Micro services

We are also getting the core sets of services. We're talking about micro services. So, as you may have heard, service fabric. It is another way of managing applications that are running. Virtual machine functions are small pieces of code that you can write even in the browser. There's a function editor built into the portal. Logic apps very much remind me of SQL Server Integration Services or Windows Workflow, where you've got logical steps, either in parallel or in serial, that happen one after another: if statements, conditional loops, et cetera. API management is a powerful service that you can put into an API to throttle it and secure it, put some rules in place, or even modify the data as it comes and goes. And finally, we talked about containers.

And containers are effectively a micro service. You can create small, multiple small-container apps, run them in a cooper service, and they basically become a micro service. Another one of the foundational technologies, of course, is networking. Now, networking is actually a fairly big topic, and I would imagine that in the cloud there are dozens and dozens of services related to networking. So I'm going to come down into four categories.

So networking can be broken into connectivity, security delivery, and monitoring. So the connectivity services in cloud computing are basically what you expect when you're thinking about networking. This would normally be cables and wired hub switches on your physical network. But this is all software in the cloud. So it's called a full network because it's just a database entry. Microsoft already has their own physical network, and they're not plugging and unplugging cables based on your commands. Area network Virtual Wayne allows your offices to connect to each other using Azure as the middleman. Express routing is a much faster way to connect your office to Azure. It costs a bit more, but it's a private network; it doesn't run over the Internet; it's encrypted; and it's faster. Of course, if you want to use an express route, you can use a traditional VPN.

There are point-to-site and site-to-site VPNs. That way, your office or your computer can connect to an Azure network securely. It's encrypted. It does run over the Internet, but people shouldn't be able to spy on your traffic. We've got a section, of course, talking about the Azure DNS service. It's basically a way of having private or like-domain names managed by the name servers within Azure.

Peering is a way to bring multiple virtual networks together so that you can have your services in one region talking to the services another. By default, these things are fairly cut off from each other for security purposes. Denied by default is a big thing. But if you can set up a peering relationship, then you can allow traffic to go through. And Azure Bastian, while relatively new, has been around it for a couple of years. However, it enables you to remote desktop into a server without the need to open the RDP ports surrounding the RDP software. It is basically a more secure version of RDP.

Now the second category of network king is called "delivery," and basically this is how traffic is routed. Sorry, security rephrase. The second category of networking is called secure, and we're living in the cloud world, where hackers are things that you have to basically deal with. As a result, Microsoft offers a variety of services that allow you to shape your trick and prevent unauthorized and authorized people from accessing it. So Network Secure has a fairly simplistic access control list style. Azure Private Link allows you to take what used to be public endpoints and turn them into private endpoints and then connect to them. Denial of service protection.

Basic is free by default. You can upgrade to the standard version, which protects your applications with intelligent protection against hackers or denial of service attacks. Effective Firewall: Of course most applications are going to need a firewall, and you're going to want to look into the Azure file service. Another type of firewall is the Web Application Firewall. This is built into the application gateway product. There is also a version for Azure Front Door, which we'll talk about in a second. But it's basically a firewall that can arise from some of the top ten or top 20 most common types of attacks. cross-site scripting and SQL injection and all those things. And finally, a virtual network endpoint.

So the third category of networking is called delivery. This to me is like a traffic shaping or a balancing type of networking service. The CDN Content Delivery Network service isn't here. Azure Front Door is like a global load balancer. Traffic Manager is a cool little hack of the DNS that allows you to distribute traffic around the world. Load balancers come in two varieties: Apple Gateway and load balancers. one being an application-level seven load balancer, and the other being a network-level four load bouncer. And then the last category of networking is called monitoring. And so, with this being your own network, you don't have an easy way of watching traffic travel over your network.

So Azure has different services that allow you to debug problems and investigate things like, let's say, a notable connection to your Azure network. You need to understand what part of your secure blocking it. So those are the monitoring services, and it has been a long video so far, and I appreciate you still being here, but there are literally hundreds of other services. Everything from machine learning and cognitive services to media services for transcriptions of videos, the internet of things, event hubs and queues, and service bus catboats—hundreds of services are in Azure. So don't expect to be able to come in here, and I just listed you 50 services; you're not going to learn them all in a day. So just absorb what you can. Take it slow. Use your curiosity to drive you deeper into things that are more interesting to you. But yeah, there's a lot, and this has been sort of just a quick overview. I do encourage you to continue on with the course. I'm going to get into a lot of the topics that were in this video, so don't feel like I'm just sort of skimming through the topics very lightly. This is just the overview, and there are sections of the course for many of them.

PowerShell and CLI

1. Programming or Scripting on the Exam

So let's talk about how programming and scripting affect the AZ 103 exam. I do get a question from time to time: Is there programming on the AZ-103 test? Strictly speaking, there is no programming in the AZ 103 test test. You do not need to know how to access the Internet, the Azure APIs, using Net, Java, or any other programming language. But there is, and I agree that it's a pretty fine line, I agree. But scripting is an important part of being an administrator with Azure. There are three main ways of accessing your resources within Azure. Now, Azure Portal is the one that we're going to be using the most because it's a point-and-click interface and also the most visually appealing. But there are also two command lines that you can use to access your resources. One is PowerShell and the other is called CLI, which is sometimes called Bash as well.

Now, the other programming aspect would be JSON. Now JSON is a ten-language format used for defining resources and a template. And you'll also get JSON responses from some of your command lines. Now, at this point, some people say, "Well, I don't want to learn programming; I don't need to learn programming." The scripting thing seems unnecessary for my job. Why do I need this? The most important reason I want to learn scripting is automation, right? A very important part of being an administrator is being able to simplify tasks and repeat tasks. Having a script in your library that you can run if you ever want to create a virtual machine, create a user, or perform some useful task, you might want to automate that rather than remembering how to do it each time. You also put these scripts into source control.

So if you use GitHub, you can check in the scripts, and that becomes the source of truth for how you do certain things. And you can track changes over time. You can reduce errors when you do things repetitively. So when you have a ten-step process for a deployment, for instance, to have that as a scripted task instead of having to remember each step is going to reduce errors. As humans, we all make mistakes; we skip steps, put them out of order, et cetera. Typo scripts are a living form of documentation. So you may not want to sit down and write everything out in Microsoft Word to document all the things that you do on the job.

But if you have a robust library of scripts, another person can come along, look at your scripts, and they'll see exactly how you implement security, how you implement policies, et cetera. So it's a living form of documentation because if you're reusing the scripts, then that's an accurate representation of how you do things as opposed to a regular Word document, which could have been written three years ago and nobody's really sure if it's up to date, and you can ask around, "Is this the most recent documentation?" No one's ever going to give you a 100% guarantee that documentation is up-to-date, but scripts, if they're being used, are up to date.

Now, we talked about the Portal, and we're going to get into the Portal a lot more in this course. But for now, Portal.Azure.com To get to the Portal within your web browser, you can sign up for a free account if you don't have one or use the account that you do have. And in most of this course, we're going to be using the Portal. So it's a good reference to have. Now, talking about scripting and PowerShell and things like that, how is it going to appear on the test? Is Microsoft going to ask you to write a script? Are you going to have to sit down and perform tasks using a pre-formatted script? Not really, right? They don't actually have you writing a script and submitting it to them. But they do have this method called a performance-based test. People call them labs. Now, performance-based testing will fire up an actual living instance of Microsoft Azure and ask you to perform a set of tasks. Okay? So there might be seven things you need to do.

A lot of them, apparently, are independent of each other. So you're not given six things to do that have to be done in a row. You're asked to create a virtual network with the following name. You're asked to create a virtual machine on one of the existing virtual networks. You're asked to do this over here, within this resource group, et cetera, et cetera. So that should be fairly separate. But you're given a living, working live instance of Azure and perform that set of tasks. Now you are given the freedom to perform that task any way that you know how. So if it's through the Portal, you can do it that way. If it is through scripting, like PowerShell or CLI, you can do it that way. So however you perform the task, as long as you do what they ask you to do, they're going to have to check on the back end to make sure it's done. They won't follow how you did it; they'll just know that I asked you to create a virtual network with the following name containing two subnets with the following names, and you were able to create those three things, and we verified that they got created.

The second method by which you're going to be asked a "coding" or "scripting" type question is that the question itself will have some sort of code in it, and you'll be asked in the answers whether that code performs the required task. So it might say, here's the scenario. The user wants to ensure that only this person gets access to the resource group and no other people can get access to it. Does the following code accomplish this? and it will show you the code, and you can decide yes or no. And that's just a task. The other way for you to have a line of missing code is for you to choose from the following sets of code, of which the following code completes the task.

Or Microsoft loves these "drag and drop" questions. The test is only 50% multiple choice in that sense. So you'll see code on the screen, and you'll need to drag the correct components and words, which is the parameter for this, which is the value that goes where, from the left into the right to finish the script. So drag and drop will also be a common type of coding. Now, in terms of scripting, we're going to talk about doing this on your local machine in a second, but Microsoft actually provides you a command-line interface within the browser. So, if you go to Portal Azure.com, you'll notice this small icon that I've highlighted here. That is a greater-than sign with an underscore that represents the Azure Cloud Shell. When you click the Azure Cloud Shell, you are taken through a setup process in which you must create a storage account specifically for the Cloud Shell. But you can choose either Bash or PowerShell, and you're given a command-line terminal right within your browser, and you can use that command-line terminal to execute commands. So you can change from Bash to PowerShell. And right from there, since it's a storage account, you can store scripts in there. So if you have reliable scripts that youalways run, they're stored inside your storage account. Or you can just type in commands and get the Cloud Shell to do them. So on the test, if you need to do something on the command line, you can just pull up the Cloud Shell and perform your task from there. You'll see that I can run the PowerShell version check in Cloud Shell. So that is the underscore.

It's in the portal in the top menu bar. Now I want to close out this video with some tips or some advice for studying and taking the PowerShell CLI and the scripting elements of this test. So first of all, you'll notice that the question will come up asking for you to complete the code. But you don't get to choose whether you prefer PowerShell or CLI. So it's up to you to know both. Luckily, there's some intuition. We'll talk about that in a second. But you don't get to choose the language it's going to ask you in. Here's a command. What are the required parameters and what are the values that go into it? And you need to know PowerShell to answer those kinds of questions.

Obviously, you're going to need to get hands-on practice. It's very important that you have your own Portal account, get your own free account, or use your corporate account to get in there and start creating resources using the Portal. PowerShell should be used on occasion. And I'm going to try to add more resources to this course for those elements, but flip between them. And with the exam itself, particularly in labs, they're not perfect.

Even nine months later, since they've sort of come out, I'm seeing a lot of people having a variety of issues with it. So make sure you give yourself lots of time. Do not spend too much time on the question part of the test, and then leave the lab. And you get to the lab, realize you only have 30 minutes, and problems start to come up. It's slow. It took them 20 minutes to resolve. So give yourself lots of time for the labs and don't waste time on other questions. Okay, so that's sort of the overall tip for the lab part of the test.

2. Memorizing PowerShell and CLI Commands

Now, one thing that I relied on when I took the test was that it's almost impossible to have memorised all of the commands within Azure, PowerShell, and also the CLI. But the good news is that there is a kind of predictable naming system for commands. We can't assume that when we want to do something in PowerShell or CLI, Microsoft will use a consistent naming system. And I'm going to talk to you for a second about this trick.

This is again mostly for taking the test, being presented with the fact that you might not have it memorized, and which is the best way to guess it. Look at the CLI first. This is also our first exposure to what the CLI commands look like. There is a web page if you look for Azure CLI reference, and I'll put the links in the resources section of this video. But there is a reference for this. So you can go and review all the Azure CLI commands.

And I do recommend that you bunker the CLI commands for virtual machines so they follow this type of naming system. So C always starts with AZ or AZ, depending on where you're from. So the AVVM and then a verb Okay, so AZVM List will handle all of the virtual machines on your subscription. Azvm Create is starting the process of becoming a virtual machine. Of course, a lot of properties and parameters are required for that. Azvm Delete will need a virtual machine. Again, you do have to provide properties and parameters to delete a virtual machine. As we can see here, this is for virtual machines. They use the VM abbreviation "azvm" and then a verb. But then we look at something like the Azure Key Vault. Then the same naming system applies. Instead of AZVM, it's AZ Key Vault. Then you can use the same verbs to list, create, and delete keys in the key vault. As for virtual machines, we get into something a little bit more creative when it comes to virtual networks that are abbreviated as VNet. But that's actually a subcategory of the network service.

So there are actually two words: AZ network, VNet, and list. And that's how you list all the virtual items on your account. And it gets more complicated than that. If you want to talk about subnets, subnets are subcomponents of Venezuela, and visnets are subcomponents of the network. And so AZ network VNet subnet list will list you all of the subnets. Now, you do have to provide the verb work as a resource there, but basically, you can see that there is an A-Z-A verb and in the middle is an abbreviated name of the service. And sometimes it's one word. Most times it's one word; sometimes it's two words or three words, depending on the category.

Now, if we go over to PowerShell, PowerShell is also similarly predictable. There's a PowerShell reference. If you look closely, I'll re-post the link. But if you the PowerShell reference, I would recommend both for CLI power if you're into administration as a career, you should have these BOOKMARKS, you should have this readily available ifyou ever need to reference it. However, because the CLI is a ZVM list, the verb is the first part of the word, so let's get a hyphen AZ VM, which is the power shall command equivalent to AZ VM list in the CLI. Instead of create, it's new; instead of delete, it's remove.

So there isn't that consistency between the verb names in PowerShell and CLI, but just like you can go from service to service and have the same naming structure, you can go get Azvm for virtual machines, AZKeyVault for key vaults, and Z Virtual Networks for virtual networks, right? So it doesn't do the abbreviation the way that CLI does, but the consistency between the verb names is there; the AZ is always there, and the service name is just in different orders. Some have a space in CLI, which has a spacing structure, and pilots all smash together as a single word. But these are the commands that you're going to need to manage and then sort of be able to intuit when you're taking a test and they're asking you about them. For instance, about the virtual network subnets. looking at this and saying yes. even if you didn't memories this.

If you can look at this and say yes, get is a PowerShell verb. The AZ is there. Virtual Network is a proper service name. Subnet is a proper service name. Etc. So, if you look at this and a bunch of other random ones, you might be able to guess it without even knowing it because you know the naming structure. So go into those reference documents again, the links will be in the reason for this video and have a look at the way that these commands are named, recognize that pattern. And so when you take the test, you will get two or three of the questions simply because you not only memorized it but also know that that's the proper way that a PowerShell command is formatted.
