Question29: Which three of the listed items are monitored by the vSAN performance service? (Choose three.)

Question30: A three-host hybrid vSAN has been deployed. Hardware maintenance is required for one of the hosts.
What happens when the host is place into maintenance mode using the "Evacuate all data" option?

Question31: What is the VMware-recommended network configuration between the three sites in a vSAN stretched cluster?

Question32: An eight-node vSAN cluster has been deployed. vSAN fault domains are NOT configured. A virtual machine with a 100GB virtual disk (VMDK) is created on the cluster. The 100GB virtual disk is assigned a storage policy with the following rules:
Primary level of failures to tolerate = 1

Failure tolerance method = RAID-1 (Mirroring) - Performance
