A cluster has a baseline showing that a critical VM typically uses 2 GHz of CPU. After a recent update, the VM's performance degraded. Monitoring shows the VM is being throttled. The administrator wants to guarantee the VM gets at least 2 GHz without overcommitting the host. What should the administrator do?

Set a CPU limit of 2 GHz for the VM

Set a CPU reservation of 2 GHz for the VM

Migrate the VM to a host with more CPU capacity

Increase the VM's CPU shares to 'High'

Users report that a web server VM is slow. The administrator checks the cluster's performance charts and sees that the VM's network utilization is near 100% of its virtual NIC's capacity, while CPU and memory are well below thresholds. Which action should the administrator take to resolve the bottleneck?

Add a second virtual NIC to the VM and configure teaming in the guest OS

Increase the VM's memory allocation

Migrate the VM to a host with a faster physical NIC

A cluster has a mix of VMs with different performance requirements. The administrator wants to ensure that a group of VMs (e.g., production web servers) get priority over another group (e.g., development VMs) when resources are contended. Which feature should be used to achieve this?

Create two resource pools and assign the VMs to each, then set higher shares for the production pool

Set CPU limits on the development VMs to cap their usage

Use vSphere DRS affinity rules to keep VMs on separate hosts

Use vSphere HA to prioritize VMs during failover
