Sample Questions

Question #385 / 529

A company is running multiple workloads in the AWS Cloud. The company has separate units for software development. The company uses AWS Organizations and federation with SAML to grant developers permissions to manage resources in their AWS accounts. All development units deploy their production workloads into a shared production account. Recently, an incident occurred where members of one development unit modified an RDS database instance that belonged to another development unit. A solutions architect must design a solution to prevent such incidents in the future while still allowing developers to manage their own RDS instances. Which strategy meets these requirements?

A

Create separate organizational units (OUs) in AWS Organizations for each development unit. Assign the OUs to the company's AWS accounts. Create SCPs with a deny action and a StringNotEquals condition for the DevelopmentUnit resource tag matching the development unit name. Assign the SCPs to the corresponding OUs.

B

Pass a DevelopmentUnit attribute as an AWS Security Token Service (AWS STS) session tag during SAML federation. Update the IAM policy for the developers' assumed IAM role with a deny action and a StringNotEquals condition comparing the DevelopmentUnit resource tag and aws:PrincipalTag/DevelopmentUnit.

C

Pass a DevelopmentUnit attribute as an AWS STS session tag during SAML federation. Create an SCP with an allow action and a StringEquals condition for the DevelopmentUnit resource tag and aws:PrincipalTag/DevelopmentUnit. Assign the SCP to the root OU.

D

Create separate IAM policies for each development unit. In each policy, include an allow action with a StringEquals condition for the DevelopmentUnit resource tag and the development unit name. During SAML federation, use AWS STS to assign the IAM policy matching the development unit name to the assumed IAM role.

Question #342 / 529

A company hosts a web application on AWS using two Amazon EC2 instances behind an Application Load Balancer (ALB). The application relies on a MySQL database running on a separate EC2 instance, which experiences a read-heavy workload. Static content is stored on instance store volumes attached to each EC2 instance and is updated frequently, requiring manual synchronization across instances. During peak traffic hours, the database becomes a bottleneck, leading to application timeouts. Which solution will enhance the application's reliability?

A

Migrate the application to AWS Lambda functions configured as ALB targets. Use a single Amazon EBS volume for static content accessed by the Lambda functions. Migrate the database to an Amazon RDS for MySQL Multi-AZ DB cluster.

B

Containerize the application and deploy it using Amazon ECS with AWS Fargate. Use a single EBS volume mounted on the ECS cluster for static content. Enable AWS Application Auto Scaling for the ECS service. Migrate the database to Amazon RDS for MySQL Multi-AZ.

C

Re-architect the application using AWS Step Functions as ALB targets. Create an Amazon EFS file system for static content accessed by the Step Functions. Migrate the database to Amazon Aurora MySQL Serverless v2 with a reader instance.

D

Containerize the application and deploy it using Amazon ECS with AWS Fargate. Mount an Amazon EFS file system to containers for shared static content. Configure AWS Application Auto Scaling for the ECS service. Migrate the database to Amazon Aurora MySQL Serverless v2 with a reader instance.

Sample Questions

Question #550 / 557

A developer is building a healthcare application that processes sensitive patient records. The application uses Amazon CloudFront for content delivery and AWS Lambda functions to process data. Each transaction includes protected health information (PHI) that must be encrypted at the field level. Only authorized backend services should be able to decrypt specific PHI fields. Which solution meets these requirements?

A

Use Lambda@Edge to encrypt PHI fields with a symmetric AWS KMS key. Configure backend Lambda functions to decrypt the data using the same key.

B

Enable AWS Shield Advanced on the CloudFront distribution for DDoS protection. Use Lambda functions with AWS KMS to encrypt sensitive data before storage.

C

Configure CloudFront field-level encryption with an asymmetric AWS KMS key. Specify the PHI fields to encrypt and restrict decryption permissions to authorized Lambda functions.

D

Set up CloudFront to forward all headers to the origin server. Use API Gateway with AWS KMS to encrypt data at rest in Amazon S3.

Question #423 / 557

A development team wants to automatically deploy their application whenever there's a code update. Which methods can trigger the deployment pipeline? (Choose two.)

A

Store code in an AWS CodeCommit repository and configure the pipeline to start on repository updates.

B

Store code in an Amazon EBS volume and set up the pipeline to trigger on volume changes.

C

Use an Amazon S3 bucket for the source code and configure the pipeline to initiate when objects are added or modified.

D

Set up the pipeline to poll an Amazon S3 bucket every 10 minutes for changes.

E

Host the code on an Amazon EC2 instance's instance store and configure the instance to trigger the pipeline upon changes.
