VCP-VCF Administrator 2024 Question 1
Select 3An organization is planning to deploy VMware Cloud Foundation in a stretched architecture to ensure high availability across two sites. Which of the following statements about the components and architecture of VMware Cloud Foundation in this scenario are correct?
- A
vSAN is required to provide storage and synchronous data replication between the two sites.
- B
NSX is used to enable seamless networking and traffic routing between the two sites.
- C
vSphere is not needed in a stretched VMware Cloud Foundation deployment.
- D
The management domain must also be stretched across both sites in a stretched architecture.
- E
A stretched cluster requires an external witness to avoid split-brain scenarios.
Show answer and explanation
Correct answers: A, B, E
Explanation
In a VMware Cloud Foundation stretched architecture, vSAN ensures storage replication and high availability, NSX provides seamless networking, and an external witness is required to maintain cluster quorum. vSphere is always a core component of VMware Cloud Foundation, and the management domain is typically not stretched across sites.
- A. Correct.
Correct. vSAN is a mandatory component in VMware Cloud Foundation and is used to provide resilient storage across the two sites in a stretched architecture with synchronous replication.
- B. Correct.
Correct. NSX is used to ensure seamless network connectivity, routing, and security policies between the two sites in a stretched architecture.
- C. Incorrect.
Incorrect. vSphere is a fundamental component of VMware Cloud Foundation and is always required to manage compute resources, including in a stretched architecture.
- D. Incorrect.
Incorrect. The management domain in VMware Cloud Foundation is typically not stretched across sites. Only the workload domains are stretched to provide high availability across sites.
- E. Correct.
Correct. A stretched cluster requires an external witness to avoid split-brain scenarios and ensure quorum in case of a failure.
