Question #1 Topic 1

A company is preparing to launch a redesigned website on AWS. Users from around the world will download digital handbooks from the website. Which AWS solution should the company use to provide these static files securely?

A Amazon Kinesis Data Streams
B Amazon CloudFront with Amazon S3
C Amazon EC2 instances with an Application Load Balancer
D Amazon Elastic File System (Amazon EFS)

Suggested Answer: B
NOTE: Answer is B. Amazon CloudFront is a content delivery network (CDN) offered by Amazon Web Services. It integrates with Amazon S3 which is an object storage service and can store and retrieve any amount of data, at any time, from anywhere. This makes it an ideal choice for serving static files securely to users worldwide due to its capabilities of low latency delivery and secure data transfer.

Question #2 Topic 1

A company wants its Amazon EC2 instances to share the same geographic area but use redundant underlying power sources. Which solution will meet these requirements?

A Use EC2 instances across multiple Availability Zones in the same AWS Region.
B Use Amazon CloudFront as the database for the EC2 instances.
C Use EC2 instances in the same edge location and the same Availability Zone.
D Use EC2 instances in AWS OpsWorks stacks in different AWS Regions.

Suggested Answer: A
NOTE: Answer is A. Amazon EC2 instances that are in multiple Availability Zones within the same AWS Region will share the same geographic area but utilize redundant power sources. This is because each Availability Zone is isolated, but the Availability Zones in a region are connected through low-latency links. An Availability Zone is made up of one or more data centers, each with redundant power, networking, and cooling.
