QUESTION 2
A solutions architect is moving the static content from a public website hosted on Amazon EC2 instances to an Amazon
S3 bucket. An Amazon CloudFront distribution will be used to deliver the static assets. The security group used by the
EC2 instances restrict access to a limited set of IP ranges. Access to the static content should be similarly restricted.
Which combination of steps will meet these requirements? (Select TWO.)
A. Create an origin access identity (OAI) and associate it with the distribution. Change the permissions in the bucket
policy so that only the OAI can read the objects.
B. Create an AWS WAF web ACL that includes the same IP restrictions that exist in the EC2 security group. Associate
this new web ACL with the CloudFront distribution.
C. Create a new security group that includes the same IP restrictions that exist in the current EC2 security group.
Associate this new security group with the CloudFront distribution.
D. Create a new security group that includes the same IP restrictions that exist in the current EC2 security group.
Associate this new security group with the S3 bucket hosting the static content.
E. Create a new IAM role and associate the role with the distribution. Change the permissions either on the S3 bucket or
on the files within the S3 bucket so that only the newly created IAM role has read and download permissions.
Correct Answer: AB

Correct Answer: C
Amazon Simple Queue Service Amazon Simple Queue Service (SQS) is a fully managed message queuing service that
enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS eliminates the
complexity and overhead associated with managing and operating message-oriented middleware and empowers
developers to focus on differentiating work. Using SQS, you can send, store, and receive messages between software
components at any volume, without losing messages or requiring other services to be available. Get started with SQS in
minutes using the AWS console, Command Line Interface or SDK of your choice, and three simple commands. SQS
offers two types of message queues. Standard queues offer maximum throughput, best-effort ordering, and at least one delivery. SQS FIFO queues are designed to guarantee that messages are processed exactly once, in the exact
order that they are sent. Scaling Based on Amazon SQS There are some scenarios where you might think about scaling
in response to activity in an Amazon SQS queue. For example, suppose that you have a web app that lets users upload
images and use them online. In this scenario, each image requires resizing and encoding before it can be published.
The app runs on EC2 instances in an Auto Scaling group, and it\\’s configured to handle your typical upload rates.
Unhealthy instances are terminated and replaced to maintain current instance levels at all times. The app places the
raw bitmap data of the images in an SQS queue for processing. It processes the images and then publishes the
processed images where they can be viewed by users. The architecture for this scenario works well if the number of
image uploads doesn\\’t vary over time. But if the number of uploads changes over time, you might consider using
dynamic scaling to scale the capacity of your Auto Scaling group.
