Question #87 / 1019

A company uses AWS Lambda functions triggered by Amazon API Gateway to process orders and store them in an Amazon Aurora PostgreSQL database. During scheduled database maintenance periods, the Lambda functions experience connection timeouts, resulting in lost order data. A solutions architect needs to ensure that all orders are processed even when the database is undergoing maintenance.

Which solution meets these requirements?

A

Provision an Amazon RDS proxy to manage database connections. Configure the Lambda functions to connect to the RDS proxy.

B

Increase the Lambda functions' timeout setting to the maximum. Implement exponential backoff retry logic in the code to retry database writes.

C

Store the order data temporarily in Lambda ephemeral storage. Use a secondary Lambda function to process the stored data once the database is available.

D

Write the order data to an Amazon Simple Queue Service (Amazon SQS) standard queue. Deploy a separate Lambda function to consume messages from the queue and persist the data to the database.

Question #584 / 1019

A company is deploying a mission-critical application on Amazon EC2 instances that require high fault tolerance. The architecture must ensure that each instance is placed on distinct underlying hardware to minimize the risk of simultaneous failures. Which networking configuration should be used?

A

Deploy the EC2 instances in a spread placement group.

B

Distribute the EC2 instances across multiple AWS Regions.

C

Configure the EC2 instances with dedicated tenancy.

D

Launch the EC2 instances in a cluster placement group.

Sample Questions

Question #333 / 529

A company operates a web application using an Application Load Balancer (ALB) and Docker containers hosted on Amazon ECS. The application data is stored in Amazon Aurora PostgreSQL, and the container images are stored in Amazon ECR. The company requires a disaster recovery plan with an RTO of no more than 24 hours and an RPO of no more than 8 hours.

Which of the following solutions is the MOST cost-effective way to meet these requirements?

A

Deploy identical ALB, ECS, and Aurora PostgreSQL resources in two regions using AWS CloudFormation. Enable continuous cross-region replication for the database. Use Amazon Route 53 with DNS failover to redirect traffic to the secondary region during a failure. Schedule ECR image replication to the secondary region every 8 hours.

B

Store container images in ECR in two regions. Schedule automated Aurora PostgreSQL backups every 8 hours and copy backups to the secondary region. In the event of a failure, use AWS CloudFormation to deploy ALB, ECS, and Aurora PostgreSQL resources in the secondary region, restore the latest backup, and update the DNS record to point to the secondary ALB.

C

Maintain a warm standby environment in a secondary region with ALB, ECS, and Aurora PostgreSQL resources running at reduced capacity. Use cross-region read replicas for the database and ECR image replication. Configure Route 53 health checks to failover traffic automatically during a failure.

D

Implement a pilot light architecture in a secondary region with minimal ALB and ECS resources. Create hourly Aurora PostgreSQL snapshots and replicate them to the secondary region. In the event of a failure, scale up ECS resources, restore the latest snapshot, and update DNS records manually.

Question #492 / 529

A solutions architect migrated an on-premises server using AWS Server Migration Service and created an AMI. An EC2 instance launched from this AMI resides in a public subnet with a public IP but does not appear as a managed instance in AWS Systems Manager. Which two steps should the solutions architect take to resolve this issue?

A

Ensure the Systems Manager Agent is installed and running on the instance.

B

Confirm the instance has an IAM role with permissions for Systems Manager.

C

Check if a VPC endpoint for Systems Manager is configured in the VPC.

D

Verify the AWS Application Discovery Agent is properly configured.

E

Validate the service-linked roles for Systems Manager are correctly set up.

Sample Questions

Question #180 / 557

A company operates a serverless application using AWS Lambda functions triggered by Amazon API Gateway. Each Lambda function must access an Amazon RDS PostgreSQL database. To comply with security policies, all Lambda functions must use a single securely encrypted database connection string.

Which solution will meet these requirements?

A

Use IAM database authentication for RDS PostgreSQL to enable secure database connections for all Lambda functions.

B

Store the credentials in an encrypted Amazon ElastiCache cluster and retrieve them during Lambda execution.

C

Store the credentials in AWS Systems Manager Parameter Store as a secure string parameter.

D

Use Lambda environment variables encrypted with a customer-managed AWS Key Management Service (AWS KMS) key.

Question #421 / 557

A developer is deploying a serverless application to multiple AWS accounts using the AWS CDK. The application includes AWS Lambda functions that use Docker images stored in Amazon ECR. The developer successfully deployed the application to the development account in us-east-1 using cdk deploy. They are now attempting the first deployment to the staging account in us-west-2 without modifying the CDK code. The deployment fails with an error stating that the specified ECR repository does not exist.

Which command should the developer execute prior to redeployment to fix this issue?

A

cdk synth

B

cdk bootstrap

C

cdk init

D

cdk destroy
