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.
