Refer to the Exhibit.
An administrator wishes to provide Load Balanced I/O for the device shown in the Exhibit.
To meet this requirement, which setting should be changed?
A. Storage Array Type Policy = VMW_NMP_RR
B. Path Selection Policy = Round Robin (VMware)
C. Storage Array Type Policy = VMW_SATP_RR
D. Path Selection Policy = MRU (VMware)
Correct Answer: B
Explanation/Reference:
Explanation: Round Robin (RR): The VMW_PSP_RR policy uses an automatic path selection, rotating through all available paths, enabling the distribution of load across the configured paths.
For Active/Passive storage arrays, only the paths to the active controller will be used in the Round Robin policy. For Active/Active storage arrays, all paths will be used in the Round Robin policy.
Note: For logical units associated with Microsoft Cluster Service (MSCS) and Microsoft Failover Clustering virtual machines, the Round Robin pathing policy is supported only on ESXi 5.5 and later.
