This FC0-U61 practice question tests your understanding of infrastructure. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 advantages of server virtualization? (Select TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Easier backup and recovery using snapshots
Option A is correct because server virtualization allows administrators to take snapshots of virtual machines (VMs) at a specific point in time. These snapshots capture the entire VM state, including disk, memory, and power state, enabling quick and consistent backup and recovery without the complexity of traditional physical server backups.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Easier backup and recovery using snapshots
Why this is correct
Snapshots provide point-in-time recovery.

Read the scenario before looking for a memorised answer.
✗
Increased security by isolating VMs
Why it's wrong here
Isolation is good, but hypervisor vulnerabilities exist.
Virtualization adds overhead, often reducing peak performance.
✓
Better hardware utilization through consolidation
Why this is correct
Multiple VMs run on one physical server, using resources efficiently.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates mistakenly believe VM isolation guarantees security (Option B) or that virtualization eliminates OS licensing costs (Option C), when in fact isolation is a feature that requires proper configuration and licensing still applies per VM.
Detailed technical explanation
How to think about this question
Server virtualization relies on a hypervisor (Type 1, like VMware ESXi or Microsoft Hyper-V) that abstracts physical hardware resources and allocates them to VMs. Snapshots use copy-on-write technology, where changes are stored in a delta file while the base disk remains unchanged, allowing rapid rollback. In real-world scenarios, snapshots are not a substitute for full backups because they degrade performance if left active for long periods and can cause data loss if the delta file becomes corrupted.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
