Failed CCNA:DC DCICN 640-911
I am not sure if I was just not in the right state of mind, didn't take the exam seriously because I have passed CCNA and work at a NOC, or if the OCG written for 640-911 falls short and I trusted it too much to do the job. I am usually a decent test taker, and I have not failed a single test (school or certs) in my entire life...at least as long as I can remember it.
I just left a review on Amazon, and the rest of this essentially is a copy-and-paste, but will hopefully provide a tip for those using Odom and Hintz's OCG for DCICN 640-911;
Avoid it.
The 640-911 exam included topics such as different features that Nexus 2K, 5~7K supports and licenses that each come with. I don't know if I am exaggerating, but I think I may have had dozen or two questions related to vPC, vDC, FCoE, VXLAN, N2K, N5~7K, MDS, and FEX. All of these, I was expecting to learn in 640-916.
I'm not sure why Cisco approved and decided that this book can serve as the Official Certification Guide for 640-911 exam. I would not recommend using this book even as a secondary material, let alone primary material. Just study for CCNA (100-101, 200-101), skip some topics that are not covered in CCNA:DC if you are comfortable with CCNA material, and read Nexus products data sheet, license types, or some other Cisco books that cover DC material. Know basic facts such as how each features such as routing protocol or SVI must be enabled first by "feature" command, different default user modes that Nexus supports, along with other few random facts and you have basically taken all that is offered from this book that ICDN1 does not offer. I assume that the lack of necessary contents comes from objective of the 640-911 exam resembles that of a ICDN1, and just added "Nexus" at the end of each sentences;
1.0 Describe How a Network Works - 15%
2.0 Configure, Verify and Troubleshoot a Switch with VLANs and Interswitch Communications Using Nexus - 21%
3.0 Implement an IP Addressing Scheme and IP Services to Meet Network Requirements in a Medium-Size Enterprise Branch Office Network Using Nexus - 12%
4.0 Configure, Verify, and Troubleshoot Basic Router Operation and Routing on Cisco Devices Using Nexus - 52%
I don't know, I'm pretty bummed out. Not sure if I should even bother with DC track at this point.
