Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A Lambda function processes CPU-heavy JSON transformations and often runs slower than expected. The team wants to improve performance without changing the code. What should they try first?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Increase the Lambda memory setting
Increasing memory also gives Lambda more CPU, which often improves performance for CPU-bound functions.
B
Distractor review
Move the function to Amazon S3
S3 is storage, not a compute runtime, so it cannot execute the function faster.
C
Distractor review
Change the function to an ALB target
An ALB can invoke a service, but it does not inherently improve Lambda CPU performance.
D
Distractor review
Disable CloudWatch logging
Reducing logs may save a little overhead, but it will not address the main CPU bottleneck.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Increase the Lambda memory setting — Increasing the memory setting is often the first tuning step for a slow Lambda function because memory allocation also increases CPU share. For CPU-heavy transformations, this can shorten execution time without code changes. It is a simple and practical way to test whether the function is resource constrained. If needed, the team can then fine-tune memory and measure the cost-performance tradeoff. Why others are wrong: S3 cannot run code, so it is not a performance optimization option. Changing the function to an ALB target does not address the Lambda runtime resources themselves. Disabling logging might slightly reduce overhead, but it does not solve the main issue when the workload is CPU-bound.
