2V0-21.23 Question 384
Single answerYou are tasked with configuring a VMware vSphere cluster at a data center to ensure that virtual machines (VMs) remain operational during a host failure. The organization requires minimal disruption to workloads and no manual intervention during a host failure. Which feature or configuration should you implement to meet this requirement?
- A
VMware vSphere High Availability (HA)
- B
VMware vSphere Fault Tolerance (FT)
- C
vSphere Distributed Resource Scheduler (DRS)
- D
vSphere Storage vMotion
Show answer and explanation
Correct answer: A
Explanation
To ensure minimal disruption during a host failure with no manual intervention, VMware vSphere High Availability (HA) is the most appropriate feature. HA monitors hosts in a cluster and restarts VMs on surviving hosts in the event of a failure. Other options, such as Fault Tolerance (FT), DRS, or Storage vMotion, either do not meet the requirements of the scenario or are intended for other purposes.
- A. Correct.
VMware vSphere High Availability (HA) is designed to restart VMs on other hosts in a cluster automatically in the event of a host failure, ensuring minimal downtime and no manual intervention. This aligns with the organization's requirement.
- B. Incorrect.
VMware vSphere Fault Tolerance (FT) provides continuous availability by creating a live shadow VM on another host. However, it is not suitable for all workloads and may introduce performance overhead. The question does not specify the need for continuous availability or a shadow VM, so FT is not the best choice here.
- C. Incorrect.
vSphere Distributed Resource Scheduler (DRS) is used to balance workloads across hosts in a cluster based on resource utilization. While it optimizes resource usage, it does not address the requirement to handle host failures automatically.
- D. Incorrect.
vSphere Storage vMotion is used to migrate VMs' storage between datastores without downtime. This is unrelated to handling host failures and does not meet the requirement described in the scenario.
