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?

The correct answer is B. Path Selection Policy = Round Robin (VMware). In round robin (VMware) the host uses an automatic path selection algorithm rotating through all available paths. This implements load balancing across all the available physical paths. Load balancing is the process of spreading server I/O requests across all available host…

Explanation

In round robin (VMware) the host uses an automatic path selection algorithm rotating through all available paths. This implements load balancing across all the available physical paths. Load balancing is the process of spreading server I/O requests across all available host paths. The goal is to optimize performance in terms of throughput (I/O per second, megabytes per second, or response times). vcenter/index.jsp?topic=/com.vmware.vsphere.config_fc.doc_40/esx_san_config/managing _san_systems/c_setting_a_path_selection_policy.html
