- A
Migrate to a different cloud provider
Why wrong: Migrating to a different cloud provider is a drastic and expensive measure that does not address the immediate resource saturation issue.
- B
Scale up the virtual machines by increasing CPU and RAM
Why wrong: Scaling up by increasing CPU and RAM is ineffective because the provider's physical resources are already saturated; further scaling may be impossible or not improve performance.
- C
Scale out by adding more virtual desktops
Scaling out by adding more virtual desktops distributes the load across additional VMs, reducing resource contention and login times during peak hours.
- D
Disable automatic scaling
Why wrong: Disabling automatic scaling would prevent the system from adapting to demand, likely worsening performance during peak usage.
Scaling Up vs Scaling Out in Cloud VDI
This 220-1201 practice question tests your understanding of cloud computing 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 company uses a cloud-based virtual desktop infrastructure (VDI) solution. Users report that logging in takes 5 minutes during peak hours. The IT team notices that the cloud provider's resource utilization is at 95%. Which action would best resolve this issue?
Quick Answer
The correct answer is to scale up the virtual machines by increasing CPU and RAM. This is because the cloud VDI environment is experiencing resource contention at 95% utilization, meaning the existing VMs are saturated and cannot handle the login load; scaling up, or vertical scaling, adds more power to each VM, directly alleviating the bottleneck. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of the difference between scaling up vs scaling out for cloud VDI resource contention—a common trap is choosing to add more VMs (scale out), which only spreads the load across more saturated nodes without fixing the root cause of insufficient per-VM resources. Remember the mnemonic: "Up for power, out for load"—when utilization is high on existing hardware, you must scale up to increase capacity per user.
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
Scale out by adding more virtual desktops
When a cloud provider's resource utilization is at 95%, the underlying physical infrastructure is saturated. Scaling up (vertical scaling) increases the VM's resources but does not alleviate the host-level bottleneck; the provider may not allow further scaling. Scaling out (horizontal scaling) adds more virtual desktop instances, distributing the load across additional VMs and reducing login times. Migrating providers is disruptive, and disabling auto-scaling worsens performance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
