A host in the city's 911 support cluster fails, and the remaining hosts automatically power on those virtual machines. Which vSphere feature provides that restart?
Select an answer to reveal the explanation.
Short Explanation
HA is the spare firehouse: if one station goes dark, the trucks restart at the next one. That is a host-failure restart, not a continuous lockstep twin. Edge HA fails over NSX services, and DRS is about balancing load, not restarting after a crash.
Full Explanation
vSphere High Availability detects ESXi host failure and restarts affected virtual machines on remaining hosts in the cluster. Fault Tolerance maintains a live secondary VM for near-zero interruption and is not required for ordinary HA restart. NSX Edge high availability protects centralized NSX services, not general guest restart. DRS balances or places VMs using vMotion; it does not restart guests after a host outage.
