An IT administrator working in a space agency has just in installed some applications that are critical for a satellite launch mission. The administrator wants the applications to work irrespective of any operating system failure. Which vSphere 6.x feature should the administrator use?

Question

Accepted Answer

B. vSphere Fault Tolerance vSphere Fault Tolerance maintains a secondary VM in lockstep with the primary on a separate host. If any failure occurs - including an OS-level crash - the secondary immediately takes over with no interruption, making applications truly agnostic to OS failures. This is the only vSphere feature that guarantees zero recovery time objective (RTO) and zero recovery point objective (RPO).

Answer

A. vSphere HA vSphere HA restarts failed VMs on another host, but this involves downtime during the restart process, which does not satisfy the 'irrespective of OS failure' requirement.

Answer

C. vSphere Replication vSphere Replication asynchronously replicates VM data to a secondary site for disaster recovery purposes, but does not provide live failover or continuous availability.

Answer

D. vSphere Data Protection vSphere Data Protection is a backup and recovery solution, not a high-availability feature, and cannot prevent downtime caused by OS failures.
