VCP-VCF Administrator 2024 Question 91
Select 2An organization plans to deploy a VMware Cloud Foundation stretched cluster to ensure workload resilience across two physical locations. As part of the deployment, which of the following procedures must be followed to correctly configure the stretched cluster?
- A
Ensure the two sites have a minimum of 5ms round-trip latency (RTT) between them.
- B
Deploy a vSAN Witness Appliance on a third site or availability zone.
- C
Assign fault domains to each of the two physical sites.
- D
Use a single Layer 2 network to span both sites for simplified network management.
- E
Configure fault tolerance (FT) for all virtual machines in the stretched cluster.
Show answer and explanation
Correct answers: B, C
Explanation
To successfully deploy a VMware Cloud Foundation stretched cluster, it is crucial to configure a vSAN Witness Appliance for quorum management and assign fault domains to represent the two physical locations. These steps ensure optimal resilience and proper data distribution across the sites. The other options either do not meet the requirements or are not mandatory for deploying a stretched cluster.
- A. Incorrect.
This is incorrect because vSAN stretched clusters require a maximum round-trip latency (RTT) of 5ms or less, not a minimum of 5ms.
- B. Correct.
This is correct. A vSAN Witness Appliance is required in a stretched cluster to act as a quorum for ensuring data consistency during failures.
- C. Correct.
This is correct. Fault domains need to be assigned to represent the two physical locations to properly segregate data and workloads across the sites.
- D. Incorrect.
This is incorrect because stretching a Layer 2 network across sites is not a strict requirement for deploying a stretched cluster. VMware Cloud Foundation supports Layer 3 connectivity in such scenarios.
- E. Incorrect.
This is incorrect because fault tolerance (FT) is not required for all virtual machines in the stretched cluster. vSAN and fault domains already provide resilience.
