- A
Enable hardware virtualization in the BIOS.
Why wrong: Hardware virtualization is likely already enabled; it affects CPU performance, not RAM exhaustion.
- B
Reduce the RAM allocation of the 4 GB VM to 2 GB.
Reducing RAM allocation frees memory for the host and the other VM, improving overall performance. This is a quick fix without additional cost.
- C
Convert the VMs to use dynamic memory allocation.
Why wrong: Dynamic memory can help, but if the host is already out of memory, dynamic allocation may not reclaim enough quickly; reducing allocation is more direct.
- D
Move the VMs to a Type 1 hypervisor.
Why wrong: Installing a Type 1 hypervisor would require wiping the host and is not practical for a laptop; also, it does not solve the physical RAM shortage.
Quick Answer
The answer is to reduce the RAM allocation of the 4 GB VM to 2 GB. This corrects the host RAM over-allocation, which occurs when the total memory assigned to virtual machines exceeds the physical RAM available, forcing the host OS into excessive disk swapping and causing severe VM performance degradation. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of virtualization resource management and the trade-off between VM count and host memory limits—a common trap is assuming more RAM always improves VM speed, when in fact overcommitting memory starves the host and cripples performance. Remember the memory tip: “VMs are greedy, but the host eats first”—always ensure the host OS has enough headroom to avoid thrashing.
220-1201 Virtualization Concepts Practice Question
This 220-1201 practice question tests your understanding of virtualization concepts. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A technician is setting up a virtual lab on a laptop with 8 GB RAM and a dual-core CPU. The technician creates two VMs: one with 4 GB RAM and one with 2 GB RAM. The host OS is Windows 10. When both VMs are running, the laptop becomes unresponsive and the VMs are extremely slow. The technician checks resource monitor and sees that the host is using 95% of RAM. What should the technician do to improve performance without purchasing new hardware?
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
Reduce the RAM allocation of the 4 GB VM to 2 GB.
Over-allocating RAM to VMs on a host with limited memory causes swapping and poor performance. The best solution is to reduce the RAM allocated to the VMs or use dynamic memory allocation if supported. The correct answer focuses on adjusting VM memory settings, which is a practical troubleshooting step.
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.
- ✗
Enable hardware virtualization in the BIOS.
Why it's wrong here
Hardware virtualization is likely already enabled; it affects CPU performance, not RAM exhaustion.
- ✓
Reduce the RAM allocation of the 4 GB VM to 2 GB.
Why this is correct
Reducing RAM allocation frees memory for the host and the other VM, improving overall performance. This is a quick fix without additional cost.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Convert the VMs to use dynamic memory allocation.
Why it's wrong here
Dynamic memory can help, but if the host is already out of memory, dynamic allocation may not reclaim enough quickly; reducing allocation is more direct.
- ✗
Move the VMs to a Type 1 hypervisor.
Why it's wrong here
Installing a Type 1 hypervisor would require wiping the host and is not practical for a laptop; also, it does not solve the physical RAM shortage.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 practitioner preparing for the 220-1201 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.

Same concept, more angles

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. A technician is deploying a new virtual machine on a Type 2 hypervisor (hosted) for software testing. The host machine runs Windows 10 Pro with 16 GB RAM and a quad-core CPU. The test application requires 4 GB RAM and two virtual CPUs. After creating the VM with those settings, the technician notices the host becomes extremely sluggish even when the VM is idle. What is the most likely reason for this?
easy- A.The hypervisor does not support hardware acceleration for the guest OS.
- B.The host machine’s CPU does not support Intel VT-x or AMD-V.
- ✓ C.The technician allocated too much RAM to the VM, leaving insufficient memory for the host OS.
- D.The virtual switch is misconfigured, causing network loops.
Why C: Type 2 hypervisors run on top of an existing OS and share resources with the host. The host OS needs sufficient RAM for itself; allocating too much to the VM can starve the host. The correct answer highlights the common mistake of over-allocating resources to a VM on a Type 2 hypervisor.
