Question #48 / 1019

A company's web application uses an Amazon EC2 instance store to store temporary session data. The company wants to ensure that the session data is highly available across multiple instances and durably stored. What should a solutions architect recommend to meet these requirements?

A

Move the session data to Amazon ElastiCache for Memcached.

B

C

Store the session data in Amazon S3 Standard-Infrequent Access.

D

Move the session data to an Amazon Elastic File System (Amazon EFS) file system.

Question #852 / 1019

A company is developing a media sharing platform hosted on Amazon EC2 instances behind an Application Load Balancer (ALB). The EC2 instances are part of an Auto Scaling group spanning multiple Availability Zones. Users frequently upload and modify media files, such as images and videos, which must be immediately accessible across all instances. A solutions architect needs to ensure all EC2 instances have real-time access to the latest media assets with minimal latency. Which solution meets these requirements?

A

Modify the EC2 user data script in the Auto Scaling group to transfer media files from the latest launched EC2 instance. Configure the ALB to direct media uploads exclusively to the newest EC2 instance.

B

Store media assets on an Amazon Elastic File System (EFS) and mount the EFS file system on each EC2 instance. Configure the platform to access media assets directly from the mounted EFS file system.

C

Upload media assets to an Amazon S3 bucket. Configure each EC2 instance to download assets to its attached Amazon Elastic Block Store (EBS) volume during launch. Schedule an hourly S3 sync command to update the EBS volume.

D

Create an Amazon EBS volume containing the media assets and share it across all EC2 instances. Configure the platform to reference the shared EBS volume for media storage.

Sample Questions

Question #363 / 529

A company’s CISO wants to redesign their CI/CD pipeline to ensure that security patches can be deployed rapidly with minimal downtime and the ability to revert changes immediately if issues arise. The application runs on a fleet of Amazon EC2 instances behind an Application Load Balancer. The current setup uses GitHub for source control, AWS CodeBuild for building the application, and AWS CodePipeline to orchestrate the workflow triggered by GitHub commits.

Which CI/CD configuration best meets these requirements?

A

Set up CodePipeline with a deployment stage using AWS CodeDeploy configured for in-place deployments. If issues occur, deploy a new version to replace the existing instances.

B

Configure CodePipeline to use AWS CodeDeploy with a blue/green deployment strategy. If problems are detected, initiate a rollback through CodeDeploy to revert to the previous environment.

C

Implement AWS CloudFormation in CodePipeline to manage deployments through stack updates. Roll back by updating the stack with the previous template.

D

Use AWS OpsWorks in the deploy stage with rolling deployments. Roll back by deploying the previous version incrementally.

Each night, several million new shipment records are batch-loaded into the table. Throughout the day, applications query the table sporadically with high frequency on a small subset of tracking IDs. The company wants to optimize DynamoDB-related expenses without compromising performance.

A

Deploy an Amazon ElastiCache cluster in front of the DynamoDB table. Configure DynamoDB auto scaling. Purchase Savings Plans in Cost Explorer.

B

Use provisioned capacity mode. Purchase Savings Plans in Cost Explorer.

C

Deploy DynamoDB Accelerator (DAX). Continue using on-demand capacity mode. Purchase Savings Plans in Cost Explorer.

Sample Questions

Question #1 / 557

A company is deploying a serverless application using AWS Lambda. The application requires access to a legacy database that uses a password for authentication. The password must be encrypted at rest and in transit, and must be accessible to Lambda functions in multiple AWS accounts. A developer needs to implement a secure storage solution with the LEAST operational overhead.

Which solution meets these requirements?

A

Store the password as an AWS Systems Manager Parameter Store SecureString parameter encrypted with an AWS KMS AWS-managed key. Create an IAM policy allowing cross-account access to the parameter. Configure Lambda execution roles with permissions to access Parameter Store. Retrieve the parameter with decryption enabled during Lambda execution.

B

Store the password using AWS Secrets Manager with an AWS KMS customer-managed key. Attach a resource-based policy to the secret granting access to the target AWS accounts. Configure Lambda execution roles with permissions to retrieve the secret. Access the secret directly from Secrets Manager during Lambda execution.

C

Encrypt the password using an AWS KMS customer-managed key. Store the encrypted password in an Amazon S3 bucket. Create a bucket policy allowing cross-account access. Configure Lambda execution roles with S3 read permissions and KMS decrypt permissions. Retrieve and decrypt the password during Lambda execution.

D

Store the password in Amazon DynamoDB with encryption enabled using an AWS KMS AWS-managed key. Create an IAM policy allowing cross-account access to the DynamoDB table. Configure Lambda execution roles with DynamoDB read permissions. Retrieve and decrypt the password during Lambda execution.

Question #313 / 557

A company uses an Amazon API Gateway HTTP API that triggers AWS Lambda functions to handle user requests. The company needs to test a new version of the Lambda functions with 10% of its user traffic before full deployment. The testing must be isolated from the remaining 90% of users and require minimal operational overhead.

Which solution meets these requirements with the LEAST operational effort?

A

Create a new Lambda function version and configure an alias with a 10% traffic weight. Update the API Gateway integration to use the alias ARN for the Lambda function.

B

Create a new deployment stage in API Gateway with canary settings. Specify 10% of the HTTP API traffic to route to the new Lambda function version while keeping the rest on the original stage.

C

Use AWS CodeDeploy to create a deployment group with a canary configuration. Gradually shift 10% of the Lambda function traffic to the new version over time.

D

Build a new HTTP API in API Gateway with a Lambda integration for the new function version. Use Amazon Route 53 weighted routing to direct 10% of user traffic to the new API.
