Objective 3.4

SAA-C03

Determine high-performing and/or scalable network architectures.

Objective 3.4 sits in Design High-Performing Architectures, which carries 24% of the Solutions Architect Associate exam. The questions below are original, written from the official objective title above, and each explanation cites the Amazon Web Services (AWS) page it rests on.

3-4Design High-Performing Architectures

Users on three continents pull the same images from one S3 bucket, and first byte times are poor far from that Region. What do you add?

A second S3 bucket copyCopying the bucket to more Regions means running replication and steering clients yourself, and each new Region is another copy to pay for.
An S3 Transfer Acceleration URLTransfer Acceleration speeds uploads over long distances into a bucket. It caches nothing on the way out.
A CloudFront distributionCorrect · your answerCorrect. Cached objects are served from the nearest edge location without a trip to the origin.
A Global Accelerator endpointGlobal Accelerator shortens the network path to a Region and holds no content. It suits an application that cannot cache.

Correct.

Checked against docs.aws.amazon.com, August 2026

Concept

Distance costs round trips, and the only way to stop paying them is to answer the request nearer the viewer. For content that is identical for every viewer, a copy held at the edge removes the trip to the origin completely rather than making it faster.

Why C

Images and scripts are the same bytes for everyone, so they cache. Once an object sits in the edge location closest to a viewer, it is served from there immediately and the request never travels back to the bucket's Region.

Source

CloudFront delivers your content through a worldwide network of data centers called edge locations. When a user requests content that you're serving with CloudFront, the request is routed to the edge location that provides the lowest latency (time delay), so that content is delivered with the best possible performance…
