SAP-C02 Continuous Improvement for Existing Solutions Practice Question
A company is using Amazon CloudFront to deliver content to users worldwide. The origin is an S3 bucket. Users in some regions experience high latency. What is the most effective way to reduce latency?
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
✓
Use an origin shield to reduce the number of requests to the S3 bucket.
Using an origin shield reduces the number of requests directly to the S3 bucket by serving cached content from a central location, which reduces latency for users. Option A is wrong because CloudFront automatically uses a global network of edge locations; you cannot manually add more. Option B is wrong because SSL/TLS certificates do not affect latency. Option D is wrong because S3 Transfer Acceleration improves upload speeds, not download speeds to end users.
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 more CloudFront edge locations in the affected regions.
Why it's wrong here
CloudFront automatically uses available edge locations; you cannot add them manually.
- ✗
Enable CloudFront's SSL/TLS certificate using SNI only.
Why it's wrong here
SSL configuration does not reduce latency.
- ✓
Use an origin shield to reduce the number of requests to the S3 bucket.
Why this is correct
Origin shield increases cache hit ratio and reduces origin load.
- ✗
Enable S3 Transfer Acceleration on the bucket.
Why it's wrong here
Transfer Acceleration speeds up uploads, not content delivery.
