Answer: A,C,E

Explanation:

This is because when deploying a stretched cluster in a VMware Cloud Foundation environment, you must ensure that:

✑ The vSAN network, the host overlay network and the vMotion network are stretched across both availability zones12. These networks enable data replication, communication and migration between hosts in different sites.

✑ The host overlay network has DHCP enabled to provide IP addresses to hosts1. This simplifies the configuration and management of hosts in different sites.

✑ Each vSAN stretched cluster has one witness host deployed in a separate location from both availability zones12. The witness host acts as a tie-breaker in case of a site failure or split-brain scenario.
