A vSphere administrator is designing a new cluster for a mission-critical application that requires maximum availability. The cluster will consist of four ESXi hosts. Which vSphere feature should be enabled to protect against host failures while minimizing resource waste?
Trap 1: Enable vSphere DRS and set the migration threshold to the most…
DRS is for load balancing, not for failover protection.
Trap 2: Enable vSphere Fault Tolerance on all VMs in the cluster.
FT is per-VM and has limitations (e.g., vCPU count), not a cluster-level availability feature.
Trap 3: Configure vSphere Replication for all VMs to replicate to a…
This is a disaster recovery solution, not for host failure within the cluster.
- A
Enable vSphere DRS and set the migration threshold to the most aggressive setting.
Why wrong: DRS is for load balancing, not for failover protection.
- B
Enable vSphere HA and configure admission control to reserve resources for one host failure.
This provides the required availability while optimizing resource usage.
- C
Enable vSphere Fault Tolerance on all VMs in the cluster.
Why wrong: FT is per-VM and has limitations (e.g., vCPU count), not a cluster-level availability feature.
- D
Configure vSphere Replication for all VMs to replicate to a secondary site.
Why wrong: This is a disaster recovery solution, not for host failure within the cluster.
