VCP-VCF Administrator 2024 Question 92
Select 3As a VMware Cloud Foundation administrator, you are tasked with deploying a stretched cluster to provide high availability across two sites. Which of the following steps are required to successfully deploy a stretched cluster in VMware Cloud Foundation?
- A
Configure vSAN fault domains for each site.
- B
Deploy a vSphere Replication appliance for data synchronization between sites.
- C
Ensure latency between sites does not exceed 5 milliseconds.
- D
Configure a witness host in a third site or availability zone.
- E
Assign each ESXi host to the same fault domain.
Show answer and explanation
Correct answers: A, C, D
Explanation
Deploying a stretched cluster in VMware Cloud Foundation requires configuring vSAN fault domains to define site boundaries, ensuring low latency between sites (≤5ms), and deploying a witness host for quorum. These steps ensure that the stretched cluster operates correctly, provides high availability, and avoids split-brain scenarios. vSphere Replication and assigning all hosts to the same fault domain are not part of this process.
- A. Correct.
Configuring vSAN fault domains is a critical step in setting up a stretched cluster. It ensures that the cluster recognizes the separation between sites and appropriately manages the data placement and redundancy.
- B. Incorrect.
vSphere Replication is not required for a stretched cluster deployment. Stretched clusters rely on vSAN for data replication and redundancy.
- C. Correct.
Latency between sites must be less than or equal to 5 milliseconds for a stretched cluster to function properly. Higher latency can cause performance and synchronization issues.
- D. Correct.
A witness host is required for quorum in a stretched cluster. It is typically deployed in a third site or availability zone to avoid split-brain scenarios.
- E. Incorrect.
Assigning each ESXi host to the same fault domain is incorrect. In a stretched cluster, ESXi hosts need to be assigned to different fault domains corresponding to their physical locations.
