Your company is utilising CloudFront to distribute its media content to multiple regions. The content is frequently accessed by users. As a cloud architect, which of the following options would help you improve the performance of the system?

Change the origin location from an S3 bucket to an ELB

Use a faster Internet connection.

Increase the cache expiration time.

Create an “invalidation” for all your objects, and recache them.

You are building a large-scale confidential documentation web server on AWS and all of its documentation will be stored on S3. One of the requirements is that it should not be publicly accessible from S3 directly, and CloudFront would be needed to accomplish this. Which of the methods listed below would satisfy the outlined requirements? Choose an answer from the options below.

Create an Identity and Access Management (IAM) user for CloudFront and grant access tothe objects in your S3 bucket to that IAM User.

Create an Origin Access Identity (OAI) for CloudFront and grant access to the objects in your S3 bucket to that OAI.

Create individual policies for each bucket the documents are stored in, and grant access only to CloudFront in these policies.

Create an S3 bucket policy that lists the CloudFront distribution ID as the Principal and the target bucket as the Amazon Resource Name (ARN).

You are hosting a web server on an EC2 Instance. With the number of requests consuming a large part of the CPU, the response performance for the application is getting degraded. Which of the following would help alleviate the problem and provide a better response time?

Place the EC2 Instance behind a Classic Load Balancer.

Place the EC2 Instance behind an Application Load Balancer.

Place the EC2 Instance in an Auto Scaling Group with the max size as 1.

Place a CloudFront distribution in front of the EC2 Instance.

A CloudFront distribution is being used to distribute content from an S3 bucket. It is required that only a particular set of users get access to certain content. How can this be accomplished?

Create IAM Users for each user and then provide access to the S3 bucket content.

Create IAM Groups for each set of users and then provide access to the S3 bucket content.

Create CloudFront signed URLs and then distribute these URLs to the users.

Use IAM Polices for the underlying S3 buckets to restrict content.

A company has an application that delivers objects from S3 to users. Of late, some users spread across the globe have been complaining of slow response times. Which of the following additional steps would help in building a cost-effective solution and also help ensure that the users get an optimal response to objects from S3?

UseS3 Replication to replicate the objects to regions closest to the users.

Ensure S3 Transfer Acceleration is enabled to ensure all users get the desired response times.

Placean ELB in front of S3 to distribute the load across S3.

Place the S3 bucket behind a CloudFront distribution.

Your company currently has a web distribution hosted using the AWS CloudFront service. The IT Security department has confirmed that the application using this web distribution now falls under the scope of PCI compliance. Which of the following steps need to be carried out to ensure that the compliance objectives are met? Choose two answers from the choices below.
