heinously Over the last few months, in between a busy work schedule, I have been covering off the CCIE Written blueprint topics, the aim being to pass the written exam to renew my Professional level exams but more importantly, to refresh my routing and switching knowledge.
how to buy cytotec without a prescription Progress has been slower than I would have liked, having only really covered off the layer 2 topics, but I’m not discouraged as I’ve been spending more time on other topics, including Python and Nexus.
It has only been in the last few months that I’ve had more exposure to the Cisco Nexus line of switches. My company’s new data centre that will be opening in Aberdeen, UK later this year will have a healthy Nexus footprint and we are bringing more customers on-line who utilise Nexus switching. With that in mind, I arranged for all members of my team to attend a suitable course and we all agreed that getting certified on that track makes sense.
The CCNA Data Centre certification is made up of two exams:
- 640-911 DCICN Introducing Cisco Data Center Networking
- 640-916 DCICT Introducing Cisco Data Center Technologies (DCICT)
The links above take you to the relevant Cisco page. I’m a little disappointed with the exam topics, which look like they’ve been typed up by somebody who has never sat an exam in their life.
The 640-911 exam is portrayed as a subset of the CCNA R&S and so I volunteered to be the team guinea pig and sit it first, without any studying to see if my current knowledge was sufficient.
This is the first time I’ve done an IT exam with no studying whatsoever, having only decided to do it the day before I sat it. It was more of a challenge just to see exactly where this exam sat. I was pleasantly surprised, but not with Cisco’s exam topic list, which is inaccurate and misleading.
Firstly, the number of questions and the time limit was quite challenging. I swear they add more questions and knock minutes off with each iteration. Another thing that quickly became apparent in the first few questions was that my Nexus knowledge needed to be better than the exam topic list suggested. Thankfully, Cisco were asking some silly Nexus based questions in this exam that I had asked the trainer in my Nexus course only a couple of weeks ago and so I’m happy to say I got a good pass mark. Looking at the Cisco website, you might be forgiven for thinking that a CCNA R&S will allow you to fly through this exam and that Nexus knowledge is only required for the 640-916 exam. My advice would be to be more prudent and ensure your basic Nexus knowledge is in place for 640-911 too.
I have already pre-ordered the Cisco Press book for the 640-916 exam and will be going through the INE Nexus video course before booking myself in for that one to ensure my knowledge is sound. At that point, I will also have had more hands on experience, my preferred method for increasing knowledge.
I had decided quite some time ago that certification for the sake of it was not something I was interested in but with me having more and more exposure to Cisco’s data centre product line, including Nexus, MDS and UCS, I think using the CCNA DC and maybe eventually the CCNP DC certification tracks to help me focus my learning makes perfect sense.
Till the next time.
