CV0-004 Troubleshooting Practice Question
A cloud administrator is responsible for a multi-tier application hosted in a public cloud. The application consists of a web tier, application tier, and database tier. Recently, users have reported that the application is responding slowly during peak hours. The administrator checks the cloud monitoring dashboard and notices that the web tier instances are running at 90% CPU utilization, but the auto-scaling group has not triggered any scaling events. The scaling policy is set to scale out when average CPU exceeds 80% for 5 minutes. What should the administrator do to resolve this issue?
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
✓
Review the cooldown period settings of the auto-scaling group
The cooldown period settings determine how long the auto-scaling group waits before initiating another scaling activity after a previous scaling event. If the cooldown period is too long, new scaling events may be suppressed even when the CPU threshold is exceeded for the required duration. The administrator should review and potentially reduce the cooldown period to allow the auto-scaling group to respond more quickly to high CPU utilization. Option A is wrong because manual scaling is a temporary workaround and does not address the underlying auto-scaling configuration issue. Option B is wrong because increasing the CPU threshold to 95% would make scaling less sensitive, likely worsening performance during peak hours. Option D is wrong because health check configuration affects load balancer traffic routing, not the triggering of scaling events based on CPU metrics.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Manually increase the number of web tier instances
Why it's wrong here
Manual scaling does not fix the auto-scaling configuration issue.
- ✗
Increase the CPU threshold to 95% to avoid unnecessary scaling
Why it's wrong here
Increasing the threshold would prevent scaling, making the issue worse.
- ✓
Review the cooldown period settings of the auto-scaling group
Why this is correct
A long cooldown period can delay scaling even when the threshold is breached.
- ✗
Check the health check configuration of the load balancer
Why it's wrong here
Health checks affect routing, not scaling decisions.
