The answer is to create a new Lambda function with a different name to test the code changes. This approach allows you to troubleshoot Lambda timeout without affecting production because it isolates your debugging environment entirely from the live traffic, letting you adjust timeout settings, memory, or code logic freely without risking the production function’s SLA or causing customer-facing errors. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of safe deployment patterns and the principle of least disruption—a common trap is assuming that version aliases or weighted routing can safely isolate testing, but those still expose production traffic to potential failures or latency spikes. A key memory tip: think “clone, don’t touch”—duplicate the function under a new name to keep production untouched, and only promote changes after thorough validation.
SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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 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.
Option B is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Related concept
Read the scenario before looking for a memorised answer.
✗
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.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
