2V0-21.23 Question 37
Single answerAn administrator is configuring a new VMware ESXi cluster and wants to ensure that virtual machines (VMs) can restart automatically on other hosts within the cluster in case of a host failure. Which cluster feature should the administrator enable for this functionality?
- A
VMware vSphere High Availability (HA)
- B
VMware vSphere Distributed Resource Scheduler (DRS)
- C
VMware vSphere Fault Tolerance (FT)
- D
VMware vSphere Storage DRS
Show answer and explanation
Correct answer: A
Explanation
VMware vSphere High Availability (HA) is specifically designed to handle host failures by monitoring ESXi hosts and virtual machines and restarting affected VMs on other available hosts within the cluster. While other features like DRS and FT provide different functionalities in a cluster, only HA meets the requirement of restarting VMs automatically in case of a host failure.
- A. Correct.
VMware vSphere High Availability (HA) is the correct feature that ensures VMs are restarted on other hosts in the cluster in case of a host failure. HA monitors the ESXi hosts and VMs, and in the event of a failure, it restarts affected VMs on other available hosts within the cluster.
- B. Incorrect.
VMware vSphere Distributed Resource Scheduler (DRS) is primarily used for load balancing and resource optimization across hosts, not for restarting VMs after a host failure.
- C. Incorrect.
VMware vSphere Fault Tolerance (FT) provides continuous availability by maintaining a live secondary copy of a VM on another host, but it does not restart VMs in the event of a host failure.
- D. Incorrect.
VMware vSphere Storage DRS is used to manage and balance storage resources within a datastore cluster, and it does not provide VM restart capabilities for host failures.
