CV0-004 Troubleshooting Practice Question
A cloud administrator is troubleshooting an application that is experiencing intermittent timeouts. The application runs on a cloud VM and connects to a cloud database. The administrator sees no errors in the application logs but notices high network latency during peak hours. Which of the following is the MOST likely cause?
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
✓
Insufficient provisioned IOPS on the database
Insufficient provisioned IOPS can cause queue buildup and increased latency during peak loads, leading to intermittent timeouts. Option B is incorrect because schema issues would typically cause query errors or failures, not just latency. Option C is incorrect because a missing route would cause complete connectivity failure, not intermittent timeouts. Option D is incorrect because SSL misconfiguration would cause handshake failures and errors, not just latency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Insufficient provisioned IOPS on the database
Why this is correct
Low IOPS leads to queueing and increased latency under load.
- ✗
Incorrect database schema
Why it's wrong here
Schema issues cause query errors, not latency.
- ✗
SSL certificate mismatch between app and database
Why it's wrong here
SSL mismatch causes connection failures, not intermittent latency.
- ✗
Missing route table entry for the database subnet
Why it's wrong here
Missing route would cause unreachability, not intermittent timeouts.
