SK0-004 · Question #832

Which of the following factors are MOST important when selecting a server for a virtualization host? (Choose two.)

The correct answer is A. CPUs and cores B. Memory. When selecting a server as a virtualization host, CPU cores and memory are the most critical resources because multiple virtual machines share these physical resources. Insufficient CPU or RAM directly limits how many VMs can run and how well they perform.

Why each option

When selecting a server as a virtualization host, CPU cores and memory are the most critical resources because multiple virtual machines share these physical resources. Insufficient CPU or RAM directly limits how many VMs can run and how well they perform.

ACPUs and coresCorrect

CPUs and cores determine how many virtual machines can run concurrently and how much processing power is available to share among VMs - each VM requires dedicated vCPU allocations. Memory is equally critical because each VM requires its own RAM allocation, and the hypervisor itself consumes overhead; running out of RAM causes paging or prevents VM startup entirely.

BMemoryCorrect
CLocal disk space

Local disk space is less critical for virtualization hosts because VM storage is typically offloaded to SANs or NAS devices rather than local drives.

DGraphics card

Graphics cards are not a primary concern for server virtualization hosts running workloads, as VMs are typically headless and GPU resources are rarely shared.

ERemote access cards

Remote access cards (like iDRAC or iLO) are useful for management but are not a primary performance factor when sizing a virtualization host.
