Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
An application serves static images through Amazon CloudFront. The team observes higher-than-expected origin fetches, which increases origin bandwidth costs. Which change most directly improves CloudFront cache reuse to reduce origin requests for the static content?
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
Set appropriate Cache-Control headers (or origin cache settings) so CloudFront caches responses longer
Cache headers and TTL determine how long objects are kept in CloudFront’s edge caches. Longer caching for static assets increases the cache hit ratio, reducing how often requests must go back to the origin.
B
Distractor review
Disable caching for the distribution so every request goes back to the origin
Disabling caching prevents CloudFront from serving cached responses, which increases origin fetch frequency and typically increases cost and latency.
C
Distractor review
Configure CloudFront to forward all request headers and query strings to the origin
Forwarding headers/query strings increases the number of distinct cache keys, which lowers cache hit ratio and increases the number of cache misses and origin fetches.
D
Distractor review
Move the S3 bucket to a different AWS Region, without changing CloudFront caching behavior
Changing the bucket region may affect latency, but it does not directly change cache key behavior or cache TTL. If CloudFront caching behavior is unchanged, it typically will not most directly reduce origin fetches.
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: Set appropriate Cache-Control headers (or origin cache settings) so CloudFront caches responses longer — CloudFront origin requests are reduced primarily by increasing the cache hit ratio. The most direct way to do that for static content is to configure correct caching behavior—such as appropriate Cache-Control headers/TTL—so edge locations can reuse the cached objects for longer periods. When objects remain in cache, repeated viewer requests are served from edge caches instead of triggering new origin fetches, lowering origin bandwidth and request-related costs. Why others are wrong: Disabling caching forces an origin fetch for every request, increasing origin traffic. Forwarding additional headers and query strings expands cache-key variability and reduces cache hits. Moving the origin bucket region does not, by itself, change caching policy/TTL, so it is not the most direct lever to stop unnecessary origin fetches.
