AWS Certified SysOps Administrator – Associate (legacy) — Question 398

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 of 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

Using Amazon CloudFront caches the large software patches at edge locations close to global users, offloading traffic from the origin web servers and drastically reducing costs and server load. Scaling out web servers or provisioning IO1 storage would significantly increase costs without addressing the root issue of global distribution efficiently. Upgrading NAT instances does not resolve the web server bottleneck or optimize content delivery for global users.
