Question # 33

An ecommerce company is experiencing an increase in user traffic. The company's store is deployed on Amazon EC2 instances as a two-tier web application consisting of a web tier and a separate database tier. As traffic increases, the company notices that the architecture is causing significant delays in sending timely marketing and order confirmation email to users. The company wants to reduce the time it spends resolving complex email delivery issues and minimize operational overhead.

What should a solutions architect do to meet these requirements?

Create a separate application tier using EC2 instances dedicated to email processing.

Configure the web instance to send email through Amazon Simple Email Service (Amazon SES).

Configure the web instance to send email through Amazon Simple Notification Service (Amazon SNS)

Create a separate application tier using EC2 instances dedicated to email processing. Place the instances in an Auto Scaling group.

Question # 34

A company is running a multi-tier web application on premises. The web application is containerized and runs on a number of Linux hosts connected to a PostgreSQL database that contains user records. The operational overhead of maintaining the infrastructure and capacity planning is limiting the company's growth. A solutions architect must improve the application's infrastructure.

Which combination of actions should the solutions architect take to accomplish this? (Choose two.)

Migrate the PostgreSQL database to Amazon Aurora

Migrate the web application to be hosted on Amazon EC2 instances.

Set up an Amazon CloudFront distribution for the web application content.

Set up Amazon ElastiCache between the web application and the PostgreSQL database.

Migrate the web application to be hosted on AWS Fargate with Amazon Elastic Container Service (Amazon ECS).

Which solution will meet these requirements?

Store the MP3 files on a set of Amazon EC2 instances that have Amazon Elastic Block Store (Amazon EBS) volumes attached. Manage access to the files by creating an IAM user and an IAM policy for each premium user.

Store all the MP3 files in an Amazon S3 bucket. Create a presigned URL for each MP3 file. Share the presigned URLs with the premium users.

Store all the MP3 files in an Amazon S3 bucket. Create an Amazon CloudFront distribution that uses the S3 bucket as the origin. Generate CloudFront signed cookies for the music files. Share the signed cookies with the premium users.

Store all the MP3 files in an Amazon S3 bucket. Create an Amazon CloudFront distribution that uses the S3 bucket as the origin. Use a CloudFront signed URL for each music file. Share the signed URLs with the premium users.

Question # 36

An application runs on Amazon EC2 instances across multiple Availability Zones The instances run in an Amazon EC2 Auto Scaling group behind an Application Load Balancer The application performs best when the CPU utilization of the EC2 instances is at or near 40%.

What should a solutions architect do to maintain the desired performance across all instances in the group?

Use a simple scaling policy to dynamically scale the Auto Scaling group

Use a target tracking policy to dynamically scale the Auto Scaling group

Use an AWS Lambda function to update the desired Auto Scaling group capacity.

Use scheduled scaling actions to scale up and scale down the Auto Scaling group

Question # 39

A company runs a high performance computing (HPC) workload on AWS. The workload required low-latency network performance and high network throughput with tightly coupled node-to-node communication. The Amazon EC2 instances are properly sized for compute and storage capacity, and are launched using default options.

What should a solutions architect propose to improve the performance of the workload?

Choose a cluster placement group while launching Amazon EC2 instances.

Choose dedicated instance tenancy while launching Amazon EC2 instances.

Choose an Elastic Inference accelerator while launching Amazon EC2 instances.

Choose the required capacity reservation while launching Amazon EC2 instances.

Question # 40

A company is developing a file-sharing application that will use an Amazon S3 bucket for storage. The company wants to serve all the files through an Amazon CloudFront distribution. The company does not want the files to be accessible through direct navigation to the S3 URL.

What should a solutions architect do to meet these requirements?

Write individual policies for each S3 bucket to grant read permission for only CloudFront access.

Create an IAM user. Grant the user read permission to objects in the S3 bucket. Assign the user to CloudFront.

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

Create an origin access identity (OAI). Assign the OAI to the CloudFront distribution. Configure the S3 bucket permissions so that only the OAI has read permission.
