An engineer wants to have a resilient access layer in data center so that switches on the access layer have separate physical connections to a pair of redundant distribution switches.
Which technology achieves this goals?
A . PaGP
B . LACP
C . VSL
D . EVPC
E . VSS
F . ECMP
Answer: D
Explanation:
Enhanced vPC is a form of Multichassis EtherChannel and VSS by itself, withour MEC, doesn’t provide resiliency.
ECMP could also be a correct answer, assuming an L3 access layer design. But the question specifies “in the Data Centre” and most DC access layer designs are L2.
Furthermore, (E)vPC is a tech exclusive to Nexus, which is marketed by Cisco as DC switches.
