Key Benefits of Using Virtual Machines: Easy Migration and Multiple Operating Systems
Which TWO of the following are benefits of using virtual machines? (Choose two.)
Quick Answer
The answer is that virtual machines allow multiple operating systems to run on a single physical machine and can be easily migrated between host systems. This is correct because each virtual machine is encapsulated into portable files—such as .vmdk or .vhdx—that contain the entire guest OS, applications, and configuration, enabling seamless movement using technologies like vMotion or live migration for load balancing and disaster recovery. On the CompTIA ITF+ FC0-U61 exam, this question tests your understanding of virtualization’s core advantages, often appearing as a “choose two” item where distractors might include “increased hardware cost” or “reduced security.” A common trap is confusing benefits with features like snapshots, which support but are not the primary benefit. Remember the mnemonic “MOVE OS”: Migration and Operating Systems are the two key benefits of using virtual machines.
⚠ Common exam trap
CompTIA often tests the misconception that virtualization eliminates all security risks or always improves performance, when in reality it introduces new attack surfaces and incurs overhead.

Correct answer & explanation
✓
They can be easily migrated between host systems
Virtual machines are encapsulated into files (such as .vmdk or .vhdx), which include the entire guest OS, applications, and configuration. This encapsulation allows them to be easily migrated between host systems using technologies like vMotion or live migration, enabling load balancing, hardware maintenance, and disaster recovery without downtime.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
They require less software to operate
Why it's wrong here
They require hypervisor.
- ✓
They can be easily migrated between host systems
Why this is correct
Migration is a benefit.
- ✓
Multiple operating systems can run on a single physical machine
Why this is correct
Key benefit of VMs.
- ✗
They provide inherent security from all threats
Why it's wrong here
No inherent security.
- ✗
Virtual machines always run faster than physical machines
Why it's wrong here
VMs have overhead, not faster.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which TWO of the following are benefits of virtualization in a data center?
medium- ✓ A.Improved disaster recovery capabilities
- B.Increased hardware reliability
- ✓ C.Reduced hardware footprint
- D.Enhanced physical security
- E.Simplified network configuration
Why A: Virtualization enables rapid restoration of virtual machines (VMs) from snapshots or backups, often within minutes, regardless of underlying hardware failures. This decoupling of the OS from physical hardware allows VMs to be migrated or recovered on different hosts, significantly improving recovery time objectives (RTOs) and recovery point objectives (RPOs) compared to physical server recovery.
