Question #479 / 1019

A company has an existing production environment in AWS that includes an Auto Scaling group, an Application Load Balancer, and an Amazon RDS database. They want to automate the deployment of an identical staging environment in two Availability Zones while ensuring consistency and minimizing manual configuration.

What should a solutions architect recommend to achieve this?

A

Use AWS OpsWorks to define the infrastructure and deploy it across two Availability Zones.

B

Create an AWS CloudFormation template based on the existing infrastructure and deploy it to the target environments.

C

Utilize AWS CodeDeploy to automate the provisioning of the staging environment in the required Availability Zones.

D

Configure AWS Systems Manager Automation documents to replicate the production environment into the staging environment.

Question #570 / 1019

A company operates a nightly batch processing workload on Amazon EC2 instances spread across two Availability Zones in the us-west-2 Region.

Sample Questions

Question #356 / 529

A company is migrating its on-premises infrastructure to AWS. The environment includes a mix of Windows and Linux servers, both virtualized and bare-metal, along with various database types. The company lacks a comprehensive inventory and needs to analyze application dependencies and network traffic patterns to optimize resource allocation during migration. A solutions architect must gather this data to create an effective migration strategy. Which approach addresses these requirements?

A

Use AWS Migration Evaluator to collect environment data. Deploy the AWS Application Discovery Service Agentless Collector to aggregate server details and generate a Migration Evaluator report.

B

Use AWS Migration Hub and install AWS Application Discovery Agents on all servers. Configure the Migration Hub Strategy Recommendations collector to analyze dependencies and produce a rightsizing report.

C

Run the AWS Application Discovery Service Agentless Collector on-premises and integrate it with AWS Migration Hub. Use AWS Application Migration Service to group resources and generate a Strategy Recommendations report.

D

Import the on-premises server inventory into AWS Migration Hub using the import tool. Execute Migration Hub Strategy Recommendations to create a migration plan based on the imported data.

Question #95 / 529

A company is migrating its on-premises payment-processing system to the AWS Cloud. The system includes a web frontend hosted on virtual machines, ActiveMQ for messaging between the frontend and backend, and a Kubernetes cluster running a containerized backend to handle payment transactions. The company wants to minimize application changes and reduce operational overhead.

Which solution meets these requirements with the LEAST operational overhead?

A

Create an AMI of the web server VM. Deploy it using an Amazon EC2 Auto Scaling group and an Application Load Balancer. Replace ActiveMQ with Amazon MQ. Migrate the Kubernetes backend to Amazon Elastic Kubernetes Service (Amazon EKS).

B

Replatform the web frontend using AWS Lambda with a custom runtime and Amazon API Gateway. Replace ActiveMQ with Amazon MQ. Migrate the Kubernetes backend to Amazon EKS.

C

Create an AMI of the web server VM. Deploy it using an Amazon EC2 Auto Scaling group and an Application Load Balancer. Replace ActiveMQ with Amazon MQ. Install Kubernetes on EC2 instances for the backend.

D

Create an AMI of the web server VM. Deploy it using an Amazon EC2 Auto Scaling group and an Application Load Balancer. Replace ActiveMQ with Amazon Simple Queue Service (SQS). Migrate the Kubernetes backend to Amazon EKS.

Sample Questions

Question #48 / 557

A developer is configuring an AWS Lambda function that requires credentials to access an Amazon RDS for PostgreSQL database. The credentials are currently stored in environment variables. The developer must enhance the solution by implementing secure credential storage, automatic rotation, and seamless integration with the Lambda function while minimizing management overhead. Which approach meets these requirements?

A

Store the credentials in AWS Systems Manager Parameter Store. Configure the parameter to reference the RDS database. Encrypt the parameter using the default AWS KMS key. Enable scheduled rotation using a custom Lambda function. Retrieve the parameter in the Lambda function to connect to the database.

B

Encrypt the credentials with a customer-managed AWS KMS key. Store the encrypted credentials in Amazon S3. Create a secondary Lambda function to rotate the credentials weekly. Use an Amazon EventBridge scheduled rule to trigger rotation. Update the RDS database credentials manually. Decrypt the credentials in the primary Lambda function to access the database.

C

Store the credentials in AWS Secrets Manager. Set the secret type to 'Credentials for Amazon RDS database' and select the PostgreSQL instance. Encrypt the secret with the default AWS KMS key. Enable automatic rotation configured for the secret. Retrieve the secret directly in the Lambda function to connect to the database.

D

Encrypt the credentials using AWS KMS and store them in an Amazon ElastiCache cluster. Develop a custom rotation mechanism using a Step Function workflow triggered by Amazon EventBridge. Update the RDS database credentials and ElastiCache entries during rotation. Decrypt the credentials in the Lambda function to establish database connections.

Question #56 / 557

A company is using an AWS Lambda function to process events from an Amazon DynamoDB Stream. The company recently observed slow processing of the events. A developer notices that the iterator age metric for the function is increasing and that the Lambda execution duration is consistently above normal.

Which actions should the developer take to increase the processing speed? (Choose two.)

A

Increase the number of shards in the DynamoDB Stream.

B

Decrease the timeout of the Lambda function.

C

Increase the memory allocated to the Lambda function.

D

Decrease the number of shards in the DynamoDB Stream.
