Recently I’ve passed the CCNA Data Center DCICN 640-911 exam.
The learning materials I’ve used:
- Cisco Press CCNA Data Center DCICN 640-911 Official Cert Guide
- INE.com CCNA Data Center
- CBT Nuggets CCNA Data Center DCICN 640-911
To be honest my feeling are pretty mixed. I’m very disappointed right now in CiscoPress, the official guide was a garbage, it didn’t contained half of what was on the exam. What I would recommend instead is the CCNA Data Center – Introducing Cisco Data Center Networking Study Guide: Exam 640-911 by Sybex. Also, you have to use brain dumps, otherwise you will not be able to pass this exam, not even if you read or watch everything.
The exam itself wasn’t anything new, but the questions were so poorly written, that I had to read multiple times to understand what they are actually mean.
There are native VLAN mismatch errors in both switch system logs. An engineer changed the native VLAN to VLAN 50 on switch 2. The commands
switchport trunk allowed VLAN add 50 and switchport trunk native VLAN 50 are executed on switch 2. What two events will result from executing these
commands? (Choose two.)
A. Native VLAN mismatch errors cease in the system log.
B. Native VLAN mismatch errors continue in the system log.
C. VLAN’s 10,20,31, and 50 forward traffic.
D. VLAN’s 10,20, and 31 forward traffic while 50 forwards untagged traffic.
E. VLAN’s 10, 20, and 31 forward traffic, 50 remains down.
F. Native VLAN mismatch error disables the ports on both switches.
Correct Answers: BE
It doesn’t say anything about whats configured on the other switch, you just have to guess… Not to mention, that in the question there is no VLAN 10, 20, or 31 referenced in any way.
