VCP-VMC 2024 Question 41
Select 3A company is deploying a VMware Cloud infrastructure and wants to ensure high availability and resilience for its critical applications. The design must account for host failures while minimizing downtime. Which of the following features should be implemented to meet this requirement?
- A
vSphere High Availability (HA)
- B
vSphere Fault Tolerance (FT)
- C
Distributed Resource Scheduler (DRS)
- D
VMware vSAN Stretched Cluster
- E
vSphere vMotion
Show answer and explanation
Correct answers: A, B, D
Explanation
To ensure high availability and resilience in a VMware Cloud infrastructure, a combination of features like vSphere High Availability (HA), vSphere Fault Tolerance (FT), and VMware vSAN Stretched Cluster should be implemented. These features address host and site failures, ensuring critical applications experience minimal or no downtime. While tools like DRS and vMotion are valuable for management and load balancing, they do not directly contribute to fault recovery or resilience.
- A. Correct.
vSphere High Availability (HA) restarts virtual machines on another host in the cluster if a host failure occurs, ensuring minimal downtime and high availability. This feature is essential for resilient infrastructure.
- B. Correct.
vSphere Fault Tolerance (FT) provides continuous availability by running a secondary VM in lockstep with the primary VM. This ensures zero downtime and no data loss in case of a host failure, making it crucial for high availability.
- C. Incorrect.
Distributed Resource Scheduler (DRS) is primarily used for load balancing across hosts in a cluster. While it helps maintain performance, it does not directly enable high availability or resilience against host failures.
- D. Correct.
VMware vSAN Stretched Cluster provides resilience by replicating data across multiple sites or fault domains. This ensures data availability even in the event of site or host failures, making it a key component of a resilient infrastructure.
- E. Incorrect.
vSphere vMotion allows live migration of VMs between hosts without downtime but does not automatically react to host failures. It is a useful tool for maintenance but does not directly enhance high availability.
