The vSAN host memory needs to be replaced and the entire operation is expected to take 90-120 minutes. Which vSAN advanced setting can be adjusted to avoid rebuild operations during the host hardware maintenance?
I agree with C answer

C is correct answer.
When a host is in maintenance mode (unless the Full data migration option was selected) the objects on the host will be considered "absent." vSAN will wait 60 minutes until initiating a rebuild of the absent objects on remaining hosts. This is because vSAN is not certain if the failure is transient or permanent. If the host will only be in maintenance mode for a few minutes it doesn’t make sense to completely rebuild all the objects on a different host. If the host will be offline for more than the default 60 minutes the administrator can modify the vSAN Object repair timer. As of vSAN 6.7 U1 this setting is available in the UI. This is now a cluster-wide setting and will apply to all hosts in the cluster.
