Answers
D.
5ms round-trip lime (RTT) between data sites
Suggested answer: A

Explanation:

A stretched cluster in vSAN requires a reliable, low latency Layer 3 communication from the data sites to the witness site. Therefore, an interruption of Layer 3 communication from the data sites to the witness site could cause a vSAN stretched cluster to fail. Additionally, blocked UDP ports on the firewall between data sites and high latency (RTT) of more than 5ms between data sites could also cause failure of the vSAN stretched cluster.
