This is the LiveLessons video covering the topics for the first exam needed for the CCNA Data Center certification. The other exam is DCICT 640-916.
LiveLessons videos are delivered for topics in multiple industries (actually they are all IT, but you can have such training for programming languages, just to mention other sectors of IT), not only networking, and they usually have renowned people from the industry delivering the training.
CCNA Training – Resources (Intense)
This training video is around five hours and I could notice that the author is doing a great job by clearly explaining every topic covered. The information is presented in an incremental way, that is, building foundations and then adding more and more complex notions on top. There are sections of the training where some small configuration tasks are shown or there are troubleshooting sections. The author is doing a good job explaining the steps needed to configure a feature or he is able to follow a systematic procedure to troubleshoot something that is not working. This proves didactic abilities and experience from the author side.
The video has five parts and each part has two or more lessons, as follows:
Basic Networking Concepts—This part deals with networking and OSI and TCP/IP concepts: IP, TCP, and UDP.
Layer 2 Switching Using Nexus—On the second part, the things are getting serious. Switching concepts are introduced. This part discusses fundamental things related to switching, like MAC, VLAN and CDP. Dot1q, LACP, VTP and different flavors of spanning tree protocol are introduced as well. Of course, the configuration steps of these features are also shown. The part is finished with a troubleshooting section that covers different scenarios related to the switching features. The features are configured on Nexus 5K.
IP Addressing—IPv4 and IPv6 addressing is introduced. Resembling and differentiating between the two are explained. Of course, the address types, formats for both IPv4 and IPv6 are discussed.
Layer 3 Routing Using Nexus—ARP, default gateway notions, among others, are shown in this part. As this is related to routing protocols, the protocols themselves could not have been omitted from this part. RIPv1-2, OSPF and EIGRP are discussed here. Each of them is analyzed for its particularities. Of course, everything discussed in this part is exemplified in a simple scenario with a L3 link between two Nexus 7K. Also, a small section of this part is allocated to troubleshooting techniques of routing protocols.
Security—This is only about access control Lists: types of ACLs, wildcard masking. At the end, you are shown how to configure an ACL.
As with any video of such type, it’s not meant to completely prepare you to pass the exam, no matter how many times you will be watching it. There is no way that a video could match the book that is covering the same exam topics. But this video can be used as a quick review and I would use it just before I’m going to take the exam or at the very beginning of the preparation just to see what exam topics are and to see a hands-on approach for the features covered by the exam.
There are two types of people taking this exam: The ones that have at least some networking experience and the ones that don’t have networking experience at all. If you are in the second category, then this video will give you a good starting point for your study. Of course, this is as much as a video can deliver. From the starting point, it’s up to you to find the resources that will give you more details about each topic covered in the video. If you are in first category, then you might go through this video, just to see how L2/L3 features are implemented on Nexus devices.
All in all, if you are at the beginning of your career in networking (as in no experience), then it makes some sense to buy this.
As a side note, one small thing that I noticed while watching the videos is that the OSPF section from lesson 11 cannot be viewed in full-screen size like any other lesson or the same lesson up to the point where OSPF is being discussed.
