Question

A technician is deploying virtual machines for multiple customers on a single physical host to reduce power consumption in a data center. Which of the following should be recommended to isolate the VMs from one another?

Options

AImplement a virtual firewall
BInstall HIPS on each VM
CVirtual switches with VLANs
DDevelop a patch management guide

Explanation

Virtual switches with VLANs provide network-level isolation between VMs on the same physical host by segmenting their traffic into separate broadcast domains. Each customer's VMs can be placed on a dedicated VLAN, preventing cross-customer traffic. A virtual firewall (A) can control traffic between segments but doesn't inherently isolate VMs from each other at the network level the way VLANs do. HIPS on each VM (B) provides host-level intrusion prevention but doesn't isolate network traffic between VMs. A patch management guide (D) is a documentation/process control and provides no network isolation.
