CV0-004 Troubleshooting Practice Question
A cloud administrator is troubleshooting a performance issue where a web application experiences intermittent slowdowns. The application is deployed on a public cloud IaaS with auto-scaling. What should the administrator check first?
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
✓
Verify load balancer configuration
A misconfigured load balancer can cause uneven traffic distribution, leading to intermittent slowdowns. Option B is wrong because CPU utilization spikes might be a symptom, not the root cause, and auto-scaling should handle it. Option C is wrong because database queries are a deeper layer to investigate after network and application tiers. Option D is wrong because network latency is less likely to be intermittent.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Verify load balancer configuration
Why this is correct
Load balancer misconfiguration can cause intermittent failures.
- ✗
Check CPU utilization of all instances
Why it's wrong here
CPU utilization may not be the root cause if auto-scaling is working.
- ✗
Analyze database query performance
Why it's wrong here
Database queries are a lower-level check; should start with front-end.
- ✗
Review network latency between tiers
Why it's wrong here
Network latency is usually consistent, not intermittent.
