CV0-004 Troubleshooting Practice Question
A company is experiencing high latency in their cloud-based database. The database is provisioned with SSD storage. Which THREE factors should the administrator investigate? (Choose three.)
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
✓
Network bandwidth between application and database
Options A, B, and D are correct because network bandwidth limitations between application and database can cause high latency, unoptimized database queries increase response time, and exceeding IOPS limits leads to throttling and higher latency. Option C is incorrect because the number of database replicas primarily affects read throughput and fault tolerance, not latency directly. Option E is incorrect because region latency is a fixed infrastructure property that typically does not change suddenly, so it is less likely to be the cause of a sudden latency spike.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Network bandwidth between application and database
Why this is correct
Network congestion or high latency affects database response.
- ✓
Database query optimization
Why this is correct
Poorly optimized queries increase execution time and latency.
- ✗
Number of database replicas
Why it's wrong here
Replicas help with read scaling and availability, not directly latency.
- ✓
Storage IOPS limits
Why this is correct
IOPS limits can throttle storage performance, causing latency.
- ✗
Region latency
Why it's wrong here
Region latency is a fixed geographical factor and not a typical variable to investigate for sudden latency.
