AWS Certified SysOps Administrator – Associate (legacy) — Question 719

A company website hosts patches for software that is sold globally. The website runs in AWS and performs well until a large software patch is released. The flood of downloads puts a strain on the web servers and leads to a poor customer experience.
What can the Sysops Administrator propose to enhance customer experience, create a more available web platform, and keep costs low?

Answer options

• A. Use an Amazon CloudFront distribution to cache static content, including software patches.
• B. Increase the size of the NAT instance to improve throughput.
• C. Scale out the web servers in advance of patch releases to reduce Auto Scaling delays.
• D. Move the content to IO1 and provision additional IOPS to the volume that contains the software patches.

Correct answer: A

Explanation

Amazon CloudFront acts as a content delivery network (CDN) that caches static assets like software patches at edge locations close to users, drastically reducing the load on the origin servers and lowering data transfer costs. Scaling out web servers or provisioning expensive io1 EBS volumes increases costs and does not solve the distribution bottleneck. Upgrading a NAT instance does not address the server-side capacity issues or improve global delivery efficiency.
