VCA vSphere High Availability & Fault Tolerance 2

Question 1

What is VM Component Protection (VMCP) in vSphere HA?

Accepted Answer

A feature that responds to storage connectivity failures by restarting affected VMs

Answer

VMCP detects storage accessibility failures (APD and PDL) and can restart affected VMs on hosts with healthy storage access, extending HA protection to storage failures.

Question 2

What does the 'Host Isolation Response' setting control in vSphere HA?

Accepted Answer

What happens to VMs on a host that cannot communicate with the HA master

Answer

The Host Isolation Response determines whether VMs on a network-isolated host are left running, powered off, or shut down to prevent split-brain scenarios in the cluster.

Question 3

What is required for vSphere Fault Tolerance to function?

Accepted Answer

A dedicated FT logging network, vSphere HA enabled, and compatible hardware

Answer

FT requires a dedicated FT logging network for synchronization traffic, vSphere HA to be enabled on the cluster, and hardware that supports hardware virtualization and CPU features.

Question 4

What is a vSphere HA 'VM restart priority' setting used for?

Accepted Answer

Determining which VMs get restarted first after an HA failover event

Answer

VM restart priority determines the order in which HA restarts virtual machines after a host failure, ensuring critical VMs like domain controllers start before less important workloads.

Question 5

What minimum number of ESXi hosts are required to form a vSphere HA cluster?

Accepted Answer

2 hosts

Answer

A vSphere HA cluster requires a minimum of 2 ESXi hosts so that if one fails, the surviving host can restart the VMs from the failed host.
