2V0-21.23 Question 38
Select 2An administrator is configuring a VMware ESXi cluster for a production environment. The cluster will host critical applications that require high availability and load balancing. The administrator wants to ensure that virtual machines are automatically restarted on other hosts in case of a host failure, while also distributing workloads evenly across the hosts. Which two features should the administrator enable to meet these requirements?
- A
vSphere High Availability (HA)
- B
vSphere Distributed Resource Scheduler (DRS)
- C
VMware Fault Tolerance (FT)
- D
vSphere Storage DRS
- E
VMware vMotion
Show answer and explanation
Correct answers: A, B
Explanation
To meet the requirements of automatic recovery from host failure and workload distribution, the administrator should enable vSphere High Availability (HA) and vSphere Distributed Resource Scheduler (DRS). HA ensures virtual machines are restarted on another host in case of failure, while DRS dynamically balances workloads across hosts to optimize performance. These two features together provide the desired behavior in a production environment with critical applications.
- A. Correct.
vSphere High Availability (HA) ensures that virtual machines are restarted on other available hosts in the cluster in the event of a host failure, providing high availability for critical workloads.
- B. Correct.
vSphere Distributed Resource Scheduler (DRS) automatically balances workloads across hosts in the cluster based on resource utilization, ensuring even distribution and optimal performance.
- C. Incorrect.
VMware Fault Tolerance (FT) provides continuous availability by creating a live secondary VM, but it is not designed for workload distribution or general high availability functionality for all VMs.
- D. Incorrect.
vSphere Storage DRS is used for balancing storage workloads across datastores, not for host failure recovery or workload balancing across hosts.
- E. Incorrect.
VMware vMotion enables live migration of virtual machines between hosts but does not provide automatic workload balancing or recovery in case of a host failure.
