VCP-VCF Administrator 2024 Question 89
Select 3An organization is planning to deploy a VMware Cloud Foundation stretched cluster across two sites to ensure high availability. As a VMware Cloud Foundation Administrator, which requirements must you validate before proceeding with the deployment?
- A
Both sites must have a minimum of three hosts per fault domain.
- B
The round-trip latency (RTT) between the sites must not exceed 5ms.
- C
The vSAN Witness Appliance must be deployed on a separate third site.
- D
Each site must have symmetrical network bandwidth of at least 10 Gbps.
- E
The ESXi version on hosts can vary as long as they are part of the same vSphere cluster.
Show answer and explanation
Correct answers: A, B, C
Explanation
When deploying a VMware Cloud Foundation stretched cluster, it is critical to meet specific requirements to ensure proper functionality and high availability. These include having a minimum of three hosts per fault domain, maintaining a round-trip latency of 5ms or less between sites, and deploying the vSAN Witness Appliance on a separate third site for quorum. Symmetrical network bandwidth and consistent ESXi versions are important considerations but not mandatory requirements in this context.
- A. Correct.
Correct: VMware Cloud Foundation stretched clusters require at least three hosts per fault domain to provide redundancy and meet vSAN requirements.
- B. Correct.
Correct: The round-trip latency (RTT) between the two sites must not exceed 5ms to ensure synchronous replication and optimal performance.
- C. Correct.
Correct: The vSAN Witness Appliance must be deployed on a separate third site to provide quorum during site failures.
- D. Incorrect.
Incorrect: While 10 Gbps network bandwidth is recommended for stretched clusters, symmetrical bandwidth is not a strict requirement.
- E. Incorrect.
Incorrect: All hosts in a vSphere cluster must run the same ESXi version to ensure compatibility and cluster stability.
