An administrator has configured multi-pathing using an Fiber Channel array in an active-active
configuration.
What is the expected behavior of an ESXi host when a failed preferred path becomes available
using the Fixed path selection policy for this array type?
A.
It automatically reverts to the preferred path.
B.
It continues using the current path until it is manually reverted.
C.
It resumes load balancing across all available paths.
D.
It reverts to the preferred path after the host has been restored and rebooted.
Explanation:
A is correct
If the ESXi/ESX host cannot use the preferred path or it becomes unavailable, the ESXi/ESX host selects an alternative available path. The host automatically returns to the previously defined preferred path as soon as it becomes available again.
