Users around the world are complaining that the newly launched photo-sharing site is
taking too much time to load their high-resolution images. Which two AWS services will
you use in combination to serve the files with the lowest possible latency? (SELECT
TWO) a. Amazon Glacier b. AWS Storage Gateway c. Amazon CloudFront d. Amazon S3
e. Amazon Elastic File System ANSWER c. Amazon CloudFront d. Amazon S3
You will be able to configure your application to serve the static content and reduce
latency for end-users with the help of Amazon S3 and Amazon CloudFront. You can
upload high-resolution images, videos, and other static files into Amazon S3. CloudFront
serves your content through a global network of data centers called edge locations.
This helps reduce latency by caching your content closer to your end-users.
In cases where the content is not in an edge location, Cloud Front pulls this content from
an origin such as an Amazon S3 bucket, an Amazon EC2 instance, an Amazon Elastic
Load Balancer load balancer, or even your own web server. You can use CloudFront
with serving whole websites or applications, including dynamic, static, streaming, and
,interactive content. You will be able to set your Amazon S3 bucket as the origin of your
CloudFront web distribution.

including microservices and containers. Operating at the individual request level, also
known as Layer 7, an Application Load Balancer routes traffic to targets, including EC2
instances, within Amazon Virtual Private Cloud based on the content of the request.
