AWS Certified SysOps Administrator – Associate — Question 90

A company’s customers are reporting increased latency while accessing static web content from Amazon S3. A SysOps administrator observed a very high rate of read operations on a particular S3 bucket.

What will minimize latency by reducing load on the S3 bucket?

Answer options

• A. Migrate the S3 bucket to a region that is closer to end users’ geographic locations.
• B. Use cross-region replication to replicate all of the data to another region.
• C. Create an Amazon CloudFront distribution with the S3 bucket as the origin.
• D. Use Amazon ElastiCache to cache data being served from Amazon S3.

Correct answer: C

Explanation

The correct answer is C, as creating an Amazon CloudFront distribution will cache content at edge locations, which reduces the load on the S3 bucket and lowers latency for end users. Option A does not address the current load effectively, option B may help but adds complexity without directly solving the latency issue, and option D introduces caching, which is unnecessary when a CDN like CloudFront is a more optimal solution.
