Reference the exhibit. 

A university campus has a site topology illustrated in the exhibit. Adjacent connected buildings are connected with a single 40gb layer 3 network with a RTT of 0.6ms as depicted by each line. An architect wants to configure a fault domain in each building. What would the architect need change in order to implement a fully supported vSAN Cluster? 

Answer options:

A. Enable a single Layer 2 network across all buildings for vSAN connectivity.
B. Decrease the existing RTT between the existing links by 0.1ms or more.
C. Add an additional link to the existing adjacent links to make it redundant.
D. Enable IPv6 networks across all buildings for vSAN connectivity.
