Suggested Answer: A 🗳️
What Is Amazon CloudFront?
Amazon CloudFront is a web service that speeds up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users.
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 user is routed to the edge location that provides the lowest latency (time delay), so that content is delivered with the best possible performance.
If the content is already in the edge location with the lowest latency, CloudFront delivers it immediately.
If the content is not in that edge location, CloudFront retrieves it from an origin that you've defined ג€" such as an Amazon S3 bucket, a MediaPackage channel, or an HTTP server (for example, a web server) that you have identified as the source for the definitive version of your content.
As an example, suppose that you're serving an image from a traditional web server, not from CloudFront. For example, you might serve an image,
[1]
Your users can easily navigate to this URL and see the image. But they probably don't know that their request was routed from one network to another ג€" through the complex collection of interconnected networks that comprise the internet ג€" until the image was found.
CloudFront speeds up the distribution of your content by routing each user request through the AWS backbone network to the edge location that can best serve your content. Typically, this is a CloudFront edge server that provides the fastest delivery to the viewer. Using the AWS network dramatically reduces the number of networks that your users' requests must pass through, which improves performance. Users get lower latency ג€" the time it takes to load the first byte of the file ג€" and higher data transfer rates.
You also get increased reliability and availability because copies of your files (also known as objects) are now held (or cached) in multiple edge locations around the world.

Why not D? Content seems to be static. Deploying multiple EC2 instances doesn't seem scalable or cost-effective. Redesign to S3 hosting seems to be a better option.

Correct answer is A as CloudFront can help provide the best experience for global users. CloudFront integrates seamlessly with ALB and provides and option to use custom DNS and SSL certs.
