Q1. Which statement is true regarding the port channel 100 and 101 configurations between the Nexus 7010 switches?
A. The vPC assignments on N7010-C2 are incorrectly swapped
B. N7010-C1 is not allowing any active VLAN traffic to pass on Po100 and Po101.
C. LACP is not configured to initiate negotiations.
D. The vPC peer-keepalive is down between the two Nexus 7000 switches.
Answer: A
Explanation:
The vPC assignments on N7010-C2 are incorrectly swapped.
The “show vpc” command will show you that the keepalives are active, and that there areactive VLANs. The “show port-channel summary” command shows that LACP is enabled.
Q2. Which command would you use to find the AED of an extended VLAN in a dual-homed site of an OTV network?
