Which two components are required when planning for stretched clusters in a VMware Cloud Foundation environment? (Choose two.)
In a VMware Cloud Foundation environment with stretched clusters, it is necessary to have a third site for a witness host, which provides the required quorum to maintain cluster integrity during failures. Additionally, the round-trip time (RTT) between sites must be ≤ 15 milliseconds to ensure proper synchronization and performance. These two components are essential for the setup and operation of stretched clusters to maintain high availability and data integrity.
That can be the only right combinations of Answers. In Stretched Cluster we need a third site for Witness
A. There must be separate Network Pools for each Availability Zone. B. A third site is required for a witness host. https://docs.vmware.com/en/VMware-Cloud-Foundation/4.5/vcf-admin/GUID-CDEEF4C6-7DFC-4EB5-B5F5-3C41230926F9.html
