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

The scenario involves determining how many hosts and guests a server can support based on its available RAM, specifically 32GB. In virtualization environments, it's essential to recognize that the total resources must be divided among the running hosts and their respective guests (virtual machines).

In this case, the correct choice specifies 1 host and 12 guests. This means that the server can run one hypervisor as the host, along with a total of 12 guests that are virtual machines. The calculation typically requires considering the RAM allocation. For instance, if each guest is allocated 2GB of RAM, then 12 guests would consume a total of 24GB, leaving sufficient resources for the host itself, which could be allocated about 8GB of RAM. This scenario allows for viable performance and ensures that the host server has enough resources to manage the virtualization layer while still sustaining the needs of the guest VMs.

In summary, the correct answer emphasizes the balance of resource allocation within the virtualization environment, ensuring there is enough RAM for both the host and its guests.
