VCP550 Question #12: Real Exam Question with Answer & Explanation
The correct answer is A: The virtual machines were not protected by vSphere HA at the time the failure occurred.. vSphere HA will not restart VMs that were unprotected at the time of failure, and cannot restart VMs when remaining hosts lack sufficient CPU or memory capacity.
Question
An administrator determines that when a host residing in a High Availability (HA) cluster fails, the virtual machines fail to restart on a remaining host, or will only restart after a long delay. Which two conditions would account for this behavior? (Choose two.)
Options
- AThe virtual machines were not protected by vSphere HA at the time the failure occurred.
- BDistributed Resource Scheduler was not enabled at the time the failure occurred.
- CThere is insufficient spare capacity on hosts with which the virtual machines are compatible.
- DThe virtual machines contain physical Raw Device Mappings.
Explanation
vSphere HA will not restart VMs that were unprotected at the time of failure, and cannot restart VMs when remaining hosts lack sufficient CPU or memory capacity.
Common mistakes.
- B. DRS is responsible for load balancing and initial VM placement but is not required for vSphere HA to detect a host failure and restart VMs - HA operates independently of DRS.
- D. Physical Raw Device Mappings do not prevent vSphere HA from restarting a VM; as long as the mapped LUN is accessible from the destination host, HA can restart the VM normally.
Concept tested. vSphere HA restart failure - capacity and protection status
