Refer to the exhibit. Which statement about the configuration is true?
A. The FEX has two uplinks to a single core switch.
B. Link down messages from the FEX are delayed.
C. The FEX is attached to two parent switches.
D. At least two uplinks to the FEX must be active for the FEX to come online.
I think the answer is C because we see only one side of VPC domain (one peer switch) so the config is enough to form a VPC to the FEX, so the FEX can be DualHomed and then the correct answer could be C.
T.
On a second thought C might be correct, because this question is about a vPC (virtual Port Channel). And in a dual homed vPC, we have one FEX attached to two parent switches. Here we only see one of the configurations, but they must be identical on both switches in order for the vPC to go UP. So C is the only plausible answer.
It is possible to configure FEX in a VPC (single homed or dual homed). But in this example there is just a normal port channel config. The word “VPC110” is just part of the description of the Port Channel and the Interface (typical Cisco misleading). Still, answer A is wrong because we only have one Port configured in the Po110 (at least this is what we see in the example). And also the max-pinning command of 1, which defines the number of uplinks (from 1 to 4) allowed on the FEX. So answer D is also wrong. C cannot be proved, we don’t see any output from a second switch. So maybe B is really correct.
Answer is “D”
Answer is B.
Port channel configuration is wrong. (VPC 110)
The Fex not be configured in a VPC port.
