The correct answer is D. EVPC. 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…

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.
