PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
A project to consolidate multiple physical servers into a private cloud. What is the primary benefit of using server virtualization?
⚠ Common exam trap
Candidates often confuse 'improved network speed' (Option C) with the efficiency gains from virtual switching, but virtualization actually adds latency and does not increase raw network throughput.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Reduced power consumption
Server virtualization allows multiple virtual machines to run on a single physical host, significantly reducing the number of physical servers required. This consolidation directly lowers power consumption because fewer physical machines need electricity for operation and cooling. While other benefits exist, reduced power consumption is the primary advantage in a consolidation project.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increased physical security
Why it's wrong here
Virtualization can actually increase security complexity and does not inherently improve physical security.
- ✗
Simplified licensing
Why it's wrong here
While server virtualisation abstracts hardware from the operating system, it does not alter the per-instance licensing terms of the hypervisor or guest OS; consolidated virtual machines still require individual licences, so licensing complexity often increases rather than simplifies. This option tempts because some hypervisors reduce physical socket counts, which can lower licensing costs in scenarios where the hypervisor itself bundles licence-inclusive subscriptions, but the stem’s consolidation goal targets resource pooling and hardware reduction, not licence count.
- ✗
Improved network speed
Why it's wrong here
Virtualization does not directly improve network speed; network performance depends on other factors.
- ✓
Reduced power consumption
Why this is correct
Fewer physical servers mean less power and cooling required.
