Question

An administrator is determining hardware requirements for a new, virtualized test environment. The vendor requires 8Gb of RAM for each host and 2Gb of RAM for each guest. If the server has a total of 32Gb of RAM, which of the following describes how many hosts and guests the server can support?

Options

  • A4 hosts and 0 guests
  • B2 hosts and 8 guests
  • C1 host and 12 guests
  • D1 host and 16 guests

Why each option

With 32GB total RAM, allocating 8GB to 1 host leaves exactly 24GB for guests, supporting 12 guests at 2GB each and maximizing guest density.

A4 hosts and 0 guests

Four hosts consume all 32GB of RAM (4 x 8GB = 32GB), leaving no memory available for any guest virtual machines, which defeats the purpose of a virtualized test environment.

B2 hosts and 8 guests

Two hosts consume 16GB (2 x 8GB), leaving only 16GB for guests, which supports just 8 guests - this configuration wastes 8GB of potential guest capacity by running an unnecessary second host.

C1 host and 12 guestsCorrect

One host consumes 8GB (1 x 8GB = 8GB), leaving 24GB of RAM available for guest virtual machines. Dividing the remaining 24GB by the 2GB per-guest requirement yields exactly 12 guests, fully utilizing all available RAM without exceeding capacity. This configuration minimizes host overhead and maximizes the number of test environment guests the server can support.

D1 host and 16 guests

One host requires 8GB and 16 guests would require 32GB (16 x 2GB), totaling 40GB, which exceeds the server's 32GB RAM capacity and is not a valid configuration.
