VCP-VCF Administrator 2024 Question 88
Select 2An organization is deploying a VMware Cloud Foundation (VCF) stretched cluster across two availability zones. Which of the following requirements must be met to successfully configure a stretched cluster for VCF in this scenario?
- A
The latency between the two availability zones must not exceed 10 milliseconds.
- B
Both availability zones must have access to a single shared vSAN datastore.
- C
Each availability zone must contain an equal number of ESXi hosts.
- D
A dedicated vCenter Server must be deployed for each availability zone.
- E
The management domain must be stretched across both availability zones.
Show answer and explanation
Correct answers: A, B
Explanation
To deploy a stretched cluster across availability zones in VMware Cloud Foundation, you must ensure that the latency between zones is below 10 milliseconds and that both zones have access to a shared vSAN datastore. These are critical for maintaining consistent storage and network performance for workloads running in the stretched cluster. Other requirements, such as equal ESXi hosts in each zone or a dedicated vCenter Server per zone, are not mandatory for this deployment.
- A. Correct.
Correct: Latency between the availability zones must be 10 milliseconds or lower to ensure proper performance and functionality of the stretched cluster.
- B. Correct.
Correct: A shared vSAN datastore is required to enable storage synchronization across the availability zones in a stretched cluster configuration.
- C. Incorrect.
Incorrect: While the number of ESXi hosts should ideally be balanced, it is not a strict requirement for configuring a stretched cluster.
- D. Incorrect.
Incorrect: A single vCenter Server instance is used to manage the stretched cluster across the availability zones, not one per zone.
- E. Incorrect.
Incorrect: The management domain is not stretched across availability zones; only the workload domain is stretched in a stretched cluster deployment.
