Which would be a requirement when planning the compute resources for a host computer?

• A. The host computer does not need to have enough compute resources to support the virtual machine workload.
• B. The host computer must have enough compute resources to support the virtual machine workload.
• C. The host computer must be running a support operating system.
• D. The number of virtual machines running Microsoft Windows must be known.

Answer: (B)

When planning compute resources for a host, the key requirement is that the host has enough compute resources to support the virtual machine workload. This means provisioning sufficient CPU, memory, and I/O capacity, while accounting for the hypervisor overhead and potential peak demand, so that VMs don’t contend for resources and performance stays within acceptable levels. If the host doesn’t have enough resources, VM performance will suffer, and operations like migrations or throttling may occur, potentially impacting SLAs. Some virtualization setups run on bare-metal hypervisors, which don’t require a separate supporting operating system, so having an additional OS isn’t universally required. You don’t need to know the exact number of Windows VMs to plan capacity; planning is based on workload profiles and anticipated growth, with margins for future demand.
