SAP-C02 Continuous Improvement for Existing Solutions Practice Question
A company has a production AWS Lambda function that processes orders. The function's execution time has increased, causing timeouts. The team wants to troubleshoot without affecting production traffic. What should they do?
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
✓
Create a new Lambda function with a different name to test the code changes.
Creating a separate Lambda function with the same code but a different name allows testing and debugging without impacting the production function. Option A is wrong because version aliases can route traffic but still affect production. Option C is wrong because CloudWatch Logs will show the production function's logs. Option D is wrong because changing the timeout directly on the production function could break the SLA.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable detailed CloudWatch Logs for the production function and analyze them.
Why it's wrong here
Analysis may help but does not isolate the testing from production impact.
- ✓
Create a new Lambda function with a different name to test the code changes.
Why this is correct
A separate function isolates testing from production.
- ✗
Use a Lambda alias to route a percentage of traffic to a new version with increased timeout.
Why it's wrong here
This still affects a portion of production traffic.
- ✗
Increase the timeout of the production Lambda function temporarily.
Why it's wrong here
Changing production timeout could cause unexpected behavior and performance issues.
