A company plans to migrate a critical application to a vSphere cluster. Before the migration, the administrator wants to establish a performance baseline to compare against after the migration. Which approach should the administrator take to create a meaningful baseline?

Use the default vSphere performance charts for the cluster after the migration and assume they represent the baseline

Configure vSphere DRS to automatically balance the cluster and use its recommendations as the baseline

Collect performance data from the current physical servers for at least a full business cycle, including peak and off-peak periods

Run a synthetic benchmark tool on the physical servers for one hour and record the results

A cluster has a baseline showing that the average CPU utilization is 60% and memory utilization is 70%. After a change, the administrator wants to see if the change improved performance. Which metric should be compared to the baseline to determine improvement?

Network throughput and storage I/O

CPU ready time and memory swapping

CPU utilization and memory utilization

In vSphere, what is the purpose of setting a reservation on a virtual machine?

To prioritize the VM over other VMs in contention

To automatically scale the VM's resources based on demand

To limit the maximum resource usage of the VM

To guarantee a minimum amount of a resource for the VM

An administrator is troubleshooting a storage performance issue in a cluster. Users report slow database queries. Monitoring shows high latency on a datastore, but the host's CPU and memory are fine. Which metric should the administrator examine to confirm a storage bottleneck?

Datastore 'Read latency' and 'Write latency'

After optimizing a cluster, an administrator wants to verify the impact of the changes. The administrator has a baseline from before the optimization. Which monitoring approach should be used to measure the optimization's effectiveness?

Check the cluster's current CPU and memory utilization against the default thresholds

Compare current performance metrics to the baseline during the same time period and workload conditions

Review the vSphere DRS recommendation history for the past month

Run a stress test on the cluster and compare to the baseline
