Question #138 / 1019

A company operates a logistics application on AWS. Each shipment request is published as a message in an Apache ActiveMQ queue running on an Amazon EC2 instance in a single Availability Zone. These messages are processed by a backend application running on a separate EC2 instance, which then stores the data in a MySQL database on another EC2 instance. All instances are in the same Availability Zone. The company wants to redesign the architecture for maximum availability with minimal operational effort. What should a solutions architect recommend?

A

Migrate the ActiveMQ queue to a Multi-AZ Auto Scaling group. Create a Multi-AZ Auto Scaling group for the backend application. Migrate the database to Amazon RDS for MySQL configured for Multi-AZ deployment.

B

Migrate the ActiveMQ queue to Amazon MQ with active/standby brokers. Deploy the backend application on a Multi-AZ Auto Scaling group. Migrate the database to Amazon RDS for MySQL with Multi-AZ deployment.

C

Deploy the ActiveMQ queue, backend application, and MySQL database each on their own Multi-AZ Auto Scaling groups.

D

Migrate the ActiveMQ queue to Amazon MQ with active/standby brokers. Deploy the backend application on EC2 instances in multiple Availability Zones. Migrate the database to a Multi-AZ Auto Scaling group.

Question #615 / 1019

A company operates a distributed application on Amazon EKS using a microservices architecture. They require a solution to collect, aggregate, and visualize both application metrics and log data in a centralized dashboard with minimal configuration. Which solution fulfills these requirements?

A

Deploy the Amazon CloudWatch agent as a DaemonSet in the EKS cluster. Use CloudWatch dashboards to view the aggregated data.

B

Implement AWS X-Ray for tracing and integrate it with Amazon Managed Service for Prometheus to store metrics. Use Grafana for visualization.

C

Enable AWS CloudTrail to capture API activity and send logs to Amazon S3. Use Amazon QuickSight for analysis and reporting.

D

Enable Amazon CloudWatch Container Insights for the EKS cluster. Access the metrics and logs through pre-configured dashboards in the CloudWatch console.

Sample Questions

Question #493 / 529

A company is using AWS SAM for deploying serverless applications. All application code and templates are stored in Amazon S3 buckets with versioning enabled. Developers access an Amazon EC2 instance hosting a cloud-based IDE. They download code from S3, make changes, run unit tests locally, and upload the modified code back to S3. The team aims to enhance their deployment process by adopting CI/CD with AWS CodePipeline.

The developers must meet these requirements:

- Utilize AWS CodeCommit for source control.

- Automate unit testing and security checks.

- Notify developers immediately if unit tests fail.

- Dynamically toggle application features and customize deployments within the CI/CD pipeline.

- Require approval from the lead developer prior to production deployment.

Which solution fulfills these requirements?

A

Use AWS CodeBuild to automate unit tests and security scans. Configure an Amazon EventBridge rule to trigger Amazon SNS notifications when tests fail. Implement AWS CDK constructs with a feature toggle manifest file to enable/disable features dynamically. Include a manual approval step in the pipeline for the lead developer's review before deployment.

B

Use AWS Step Functions to orchestrate unit tests and security scans. Use Amazon CloudWatch Logs to detect test failures and send alerts via Amazon SES. Deploy feature toggles using AWS CloudFormation parameters and conditions. Integrate an Amazon SQS queue for the lead developer to approve deployments asynchronously.

C

Use AWS Lambda functions to execute unit tests and security scans. Configure an Amazon CloudWatch Events rule to send alerts via Amazon SNS upon test failures. Manage feature toggles using AWS Systems Manager Parameter Store and update parameters during deployment. Use AWS CodeDeploy hooks for the lead developer's approval.

D

Use Jenkins pipelines within AWS to run unit tests and security scans. Trigger Amazon SNS alerts via AWS CLI commands in the pipeline when tests fail. Implement feature flags using Amazon DynamoDB and custom scripts. Require the lead developer to approve deployments via an Amazon API Gateway endpoint.

Question #221 / 529

A company uses AWS Organizations to manage its multiple AWS accounts. The company requires a consolidated report of all Amazon EC2 instances across the organization that have consistently low CPU utilization or excess memory capacity. They also need automated recommendations for resizing these instances to optimize costs. Which solution meets these requirements with the LEAST administrative effort?

A

Deploy a third-party monitoring solution from AWS Marketplace on all EC2 instances to collect CPU and memory metrics. Aggregate the data in an Amazon RDS database. Develop a custom application to analyze the data and generate resizing recommendations based on EC2 instance specifications and pricing.

B

Use AWS Systems Manager to install the Amazon CloudWatch agent on all EC2 instances. Access AWS Cost Explorer's resource optimization feature from the organization\u2019s management account to obtain recommendations. Implement the provided suggestions to resize underutilized instances across all accounts.

C

Utilize AWS Systems Manager to deploy the Amazon CloudWatch agent on each EC2 instance. Log into each member account to run AWS Cost Explorer's resource optimization tool individually. Apply the recommendations per account to resize the identified instances.

D

Install the Amazon CloudWatch agent on all instances using AWS Systems Manager. Configure an AWS Lambda function to process CloudWatch metrics and identify underutilized instances. Store the results in Amazon DynamoDB and use Amazon QuickSight to visualize the data. Manually compare findings with EC2 pricing to determine resizing options.

Sample Questions

Question #523 / 557

A developer has an application that uses AWS Security Token Service (AWS STS). The application calls the STS AssumeRole API operation to provide temporary security credentials to trusted users. The application calls AWS STS at the service's default global endpoint:

https://sts.amazonaws.com.

The application is deployed in the Europe (Frankfurt) AWS Region. The application is experiencing intermittent latency errors when calling AWS STS.

What should the developer do to resolve this issue?

A

Update the application to use the GetCallerIdentity API operation.

B

Update the application to use the AssumeRoleWithWebIdentity API operation.

C

Update the application to use a Regional STS endpoint in the Europe (Frankfurt) Region.

D

Update the application to use the AssumeRoleWithSAML API operation. Configure the STS endpoint to use a global endpoint.

Question #375 / 557

A company is building a serverless application using Amazon API Gateway HTTP API. They need to ensure that only authenticated users can invoke specific routes, and the authentication tokens must automatically expire and be refreshed periodically. Which approach meets these requirements?

A

Set up an Amazon Cognito identity pool, use the Cognito Authorizer in API Gateway, and utilize the temporary AWS credentials from the identity pool.

B

Implement a custom Lambda authorizer that validates tokens stored in a DynamoDB table, which are issued during user login and refreshed manually.

C

Configure an Amazon Cognito user pool, integrate it with API Gateway using a JWT authorizer, and use the issued access or identity tokens.

D

Create IAM roles for each user, attach a resource-based policy to the API Gateway, and use IAM authorization.
