Assuming a mirrored (RAID-1) object configuration, how many hosts must contribute storage in a non-stretched VMware vSAN cluster to satisfy the 鈥淣umber of failures to tolerate鈥?policy option?
鈥渘鈥?is the desired 鈥淣umber of failures to tolerate鈥?value for all options.
Answer: C Explanation:
If fault domains are configured, 2n 1 fault domains with hosts contributing capacity are required. A host, which is not part of any fault domain is considered its own single-host fault domain

Which two components are part of storage I/O multipathing on ESXi? (Choose two.)
Answer: A,C Explanation:
The NMP associates a set of physical paths with a specific storage device, or LUN. The specific details of handling path failover for a given storage array are delegated to a Storage Array Type Plug-In (SATP). The specific details for determining which physical path is used to issue an I/O request to a storage device are handled by a Path Selection Plug-In (PSP). SATPs and PSPs are sub plug-ins within the NMP module.
