1. Application Redundancy So we’ve been talking in this section about business continuity. Now, part of business continuity is being able to recover from a disaster, of course, and we’ve talked about that. But another aspect of business continuity is not even suffering a disaster, not having any downtime. Even when a particular component fails […]

1. Design Business Continuity (10-15%) The fourth section of the exam says “Design Business Continuity” and is worth 10 to 15% of the exam score. Underneath the topic of business continuity are two subtopics. One is backup and recovery, and the other is high availability. Now, we should deal with these together because they are […]

1. Data Monitoring Strategy So, let’s take a look at how you can monitor your databases in various ways. When we were running SQL Server in our local environments within our data centers, we certainly knew that there were places to look—little hidden corners of SQL Server—to find out the performance aspects of our databases. […]

1. Data Geo-Replication So one of the big advantages of cloud computing is its global nature of it. When you create a virtual machine, you can create it in any region of the world. And in fact, you can create your multiple virtual machines in multiple regions of the world, and you can really get […]

68. VRRP Virtual Router Redundancy Protocol Next, we have VRP. VRP is simply a virtual router redundancy protocol, similar to Cisco HSRP. The distinction is between the industry standard and the HSRP Cisco standard; they are nearly identical, but there are a few differences. We’ll see what differences they have. First of all, you can […]

61. a NTA Lab Let us perform the lab task. R1 is the router in this lab. So let me show you that I have a router that is connected to a switch that is 10 five.The router interface is the switch interface, and over these interfaces I’m going to enable the entity. First of […]

53. Control and Provisioning of Wireless Access Points ( CAPWAP) We have discussed the access point and the controller they have to communicate with. So how they are going to communicate is by building the cap-wrap tunnel. You can see the full form of CapWAP control and wireless access point provisioning. And there are so […]

46. Interference & Effects of Physical Objects Next topic. Interference and the effect of physical objects are present. Now, interference is nothing but noise, and this noise means that you are sending some signal and it has some overlap. You can see that there is some overlap with the same channel here. So different transmitters […]

39. BGP Best Path Selection Lab Let us perform the lab task in the lab. What we are going to do, first of all, is show you the entire setup that we have here. As you can see, we have four different autonomous systems. Say A is 50, then A is 100, which is 900, […]

32. BGP Basic Lab iBGP vs eBGP Now we have to perform the lab related to BGP. Here you can see in the diagram that I have router one in block A, which is 100. So Ace is 100, and A is 200. Route 1 and switch 105 will form an EBGP relationship, with switch […]
