220-1201 Practice Question: A company uses a cloud-based virtual desktop…
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?

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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Migrate to a different cloud provider
Why it's wrong here
Migrating to a different cloud provider is a drastic and expensive measure that does not address the immediate resource saturation issue.
- ✗
Scale up the virtual machines by increasing CPU and RAM
Why it's wrong here
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.
- ✓
Scale out by adding more virtual desktops
Why this is correct
Scaling out by adding more virtual desktops distributes the load across additional VMs, reducing resource contention and login times during peak hours.
- ✗
Disable automatic scaling
Why it's wrong here
Disabling automatic scaling would prevent the system from adapting to demand, likely worsening performance during peak usage.
