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.
This FC0-U61 practice question tests your understanding of infrastructure. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are benefits of using virtual machines? (Choose two.)
They require less software to operate
Why wrong: They require hypervisor.
They can be easily migrated between host systems
Migration is a benefit.
Multiple operating systems can run on a single physical machine
Key benefit of VMs.
They provide inherent security from all threats
Why wrong: No inherent security.
Virtual machines always run faster than physical machines
Why wrong: VMs have overhead, not faster.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
They can be easily migrated between host systems
Option B is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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.
Detailed technical explanation
Under the hood, virtual machine migration relies on techniques like pre-copy memory migration, where the hypervisor copies memory pages from the source to the destination host while the VM continues running, then briefly pauses to transfer the final dirty pages and CPU state. This process is defined by protocols such as VMware's vMotion or Microsoft's Hyper-V Live Migration, and requires shared storage or network-based replication to maintain disk consistency. In real-world scenarios, this enables seamless hardware upgrades or data center consolidation with minimal service interruption.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the FC0-U61 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Variation 1. Which TWO of the following are benefits of virtualization in a data center?
mediumWhy 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.
