DBS-C01 Management and Operations Practice Question
A company runs an Amazon Aurora MySQL database cluster with one writer and one reader instance. The application experiences intermittent connection timeouts during peak traffic. The DB cluster parameter group has 'connect_timeout' set to 5 seconds. What should a database specialist recommend to reduce connection timeouts?
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
✓
Enable RDS Proxy for the cluster.
Enabling RDS Proxy reduces connection overhead and provides a connection pool, mitigating timeouts. Option A is incorrect because adding readers does not help with writer connection timeouts; the issue is with the writer instance. Option C is incorrect because increasing connect_timeout only delays the timeout, not the root cause. Option D is incorrect because the issue is not related to TLS.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add additional reader instances to distribute the load.
Why it's wrong here
Adding readers does not help with writer connection timeouts; the issue is with the writer instance handling connections.
- ✓
Enable RDS Proxy for the cluster.
Why this is correct
RDS Proxy provides connection pooling and reduces overhead, helping to prevent timeouts during peak traffic.
- ✗
Increase the 'connect_timeout' parameter to 10 seconds.
Why it's wrong here
Increasing connect_timeout only delays the timeout, not addressing the root cause of connection delays.
- ✗
Enable IAM database authentication and require TLS.
Why it's wrong here
IAM authentication and TLS address security, not connection timeouts.
