VMware Carbon Black Cloud Enterprise EDR Specialist — Question 34

An administrator is responsible for managing a five-node vSAN cluster. The vSAN Cluster is configured with both vSphere High Availability (HA) and vSphere Distributed Resource Scheduler (DRS). The vSAN Cluster is currently hosting 150 virtual machines that have consumed 60% of the usable capacity.
Each virtual machine belongs to one of the following vSAN Storage Policies: vSANPolicy1:

Site Disaster Tolerance: None -
Failures to Tolerate: 1 failure - RAID-5 (Erasure Coding)
vSANPolicy2:

Site Disaster Tolerance: None -
Failures to Tolerate: No data redundancy
Following an unplanned power event within the data center, the administrator has been alerted to the fact that one host has permanently failed.
What will be the impact to any virtual machine that was running on the failed host using vSANPolicy1?

Answer options

• A. Each virtual machine will be restarted on another vSAN host using vSphere HA.
• B. Each virtual machine will be unavailable for up to 90 minutes while the automatic recovery process completes.
• C. vSAN will defer the start of the recovery process for 60 minutes, and the virtual machines will not power on until the recovery process has been completed.
• D. Each virtual machine must be restored from backup.

Correct answer: A

Explanation

The correct answer is A because vSphere HA is designed to restart virtual machines on other hosts in the cluster when a host fails. Options B and C incorrectly suggest that the virtual machines will be unavailable or delayed for extended periods, which is not the case with HA. Option D is incorrect because HA does not require a backup restoration for virtual machines; it facilitates automatic recovery.
