Question # 121

A DevOps engineer needs to implement integration tests into an existing AWS CodePipelme CI/CD workflow for an Amazon Elastic Container Service (Amazon ECS) service. The CI/CD workflow retrieves new application code from an AWS CodeCommit repository and builds a container image. The CI/CD workflow then uploads the container image to Amazon Elastic Container Registry (Amazon ECR) with a new image tag version.

The integration tests must ensure that new versions of the service endpoint are reachable and that vanous API methods return successful response data The DevOps engineer has already created an ECS cluster to test the service

Which combination of steps will meet these requirements with the LEAST management overhead? (Select THREE.)

Add a deploy stage to the pipeline Configure Amazon ECS as the action provider

Add a deploy stage to the pipeline Configure AWS CodeDeploy as the action provider

Add an appspec.yml file to the CodeCommit repository

Update the image build pipeline stage to output an imagedefinitions json file that references the new image tag.

Create an AWS Lambda function that runs connectivity checks and API calls against the service. Integrate the Lambda function with CodePipeline by using aLambda action stage

Write a script that runs integration tests against the service. Upload the script to an Amazon S3 bucket. Integrate the script in the S3 bucket with CodePipeline by using an S3 action stage.

Answer:

Explanation:

ï‚· Add a Deploy Stage to the Pipeline, Configure Amazon ECS as the Action Provider:

By adding a deploy stage to the pipeline and configuring Amazon ECS as the action provider, the pipeline can automatically deploy the new container image to the ECS cluster.

This ensures that the service is updated with the new image tag, making the new version of the service endpoint reachable.

[Reference: AWS CodePipeline with ECS, ï‚· Update the Image Build Pipeline Stage to Output an imagedefinitions.json File that References the New Image Tag:, The imagedefinitions.json file provides the necessary information about the container images and their tags for the ECS task definitions., Updating the pipeline to output this file ensures that the correct image version is deployed., Example imagedefinitions.json, , [, {, "name": "container-name",, "imageUri": "123456789012.dkr.ecr.region.amazonaws.com/my-repo:my-tag", }, ], , , ï‚· Reference: CodePipeline ECS Deployment, ï‚· Create an AWS Lambda Function that Runs Connectivity Checks and API Calls against the Service. Integrate the Lambda Function with CodePipeline by Using a Lambda Action Stage:, The Lambda function can perform the necessary integration tests by making connectivity checks and API calls to the deployed service endpoint., Integrating this Lambda function into CodePipeline ensures that these tests are run automatically after deployment, providing near-real-time feedback on the new deploymentâ€™s health., , Example Lambda function integration:, actions:, - name: TestService, actionTypeId:, category: Test, owner: AWS, provider: Lambda, version: 1, runOrder: 2, configuration:, FunctionName: testServiceFunction, , Reference: Integrating Lambda with CodePipeline, These steps ensure that the CI/CD workflow deploys the new container image to ECS, updates the image references, and performs integration tests, meeting the requirements with minimal management overhead., , , , ]

Question # 122

A company has deployed an application in a single AWS Region. The application backend uses Amazon DynamoDB tables and Amazon S3 buckets.

The company wants to deploy the application in a secondary Region. The company must ensure that the data in the DynamoDB tables and the S3 buckets persists across both Regions. The data must also immediately propagate across Regions.

Which solution will meet these requirements with the MOST operational efficiency?

Implement two-way S3 bucket replication between the primary Region ' s S3 buckets and the secondary Region ' s S3 buckets. Convert the DynamoDB tables into global tables. Set the secondary Region as the additional Region.

A company uses an organization in AWS Organizations to manage multiple AWS accounts. The company needs a solution to detect sensitive information in Amazon S3 buckets in all the companyâ€™s accounts. When the solution detects sensitive data, the solution must collect all the findings and make them available to the companyâ€™s security officer in a single location. The solution must move S3 objects that contain sensitive information to a quarantine S3 bucket.

Which solutions will meet these requirements with the LEAST operational overhead? (Select TWO.)

Enable AWS Security Hub in the organization. Enable Amazon Macie for all the accounts in the organization. Configure Macie to send findings to Security Hub.

Create an AWS Service Catalog product to provision S3 buckets. Configure Service Catalog to create a new S3 bucket. Configure S3 Event Notifications to send ObjectCreated events to an Amazon Simple Queue Service (Amazon SQS) queue.

Create an AWS Lambda function to copy S3 objects from S3 buckets to a dedicated quarantine bucket. Configure the Lambda function to delete copied objects from the original buckets. Configure an Amazon EventBridge rule to invoke the Lambda function in response to sensitive information findings from Amazon Macie.

Configure an AWS Lambda function to run when new objects are created or when existing objects are updated. Configure the Lambda function to determine whether objects contain sensitive data. Configure the function to move objects that contain sensitive data to a quarantine bucket and to delete the original objects.

Configure SCPs to prevent the creation of S3 buckets and objects that contain suspected sensitive data. Configure the SCPs to move objects that are suspected to contain sensitive data to a dedicated quarantine S3 bucket.

Question # 124

A healthcare services company is concerned about the growing costs of software licensing for an application for monitoring patient wellness. The company wants to create an audit process to ensure that the application is running exclusively on Amazon EC2 Dedicated Hosts. A DevOps engineer must create a workflow to audit the application to ensure compliance.

What steps should the engineer take to meet this requirement with the LEAST administrative overhead?

Use AWS Systems Manager Configuration Compliance. Use calls to the put-compliance-items API action to scan and build a database of noncompliant EC2 instances based on their host placement configuration. Use an Amazon DynamoDB table to store these instance IDs for fast access. Generate a report through Systems Manager by calling the list-compliance-summaries API action.

Use custom Java code running on an EC2 instance. Set up EC2 Auto Scaling for the instance depending on the number of instances to be checked. Send the list of noncompliant EC2 instance IDs to an Amazon SQS queue. Set up another worker instance to process instance IDs from the SQS queue and write them to Amazon DynamoDB. Use an AWS Lambda function to terminate noncompliant instance IDs obtained from the queue, and send them to an Amazon SNS

Use AWS Config. Identify all EC2 instances to be audited by enabling Config Recording on all Amazon EC2 resources for the region. Create a custom AWS Config rule that triggers an AWS Lambda function by using the " config-rule-change-triggered " blueprint. Modify the LambdaevaluateCompliance () function to verify host placement to return a NON_COMPLIANT result if the instance is not running on an EC2 Dedicated Host. Use the AWS Config repo

Use AWS CloudTrail. Identify all EC2 instances to be audited by analyzing all calls to the EC2 RunCommand API action. Invoke a AWS Lambda function that analyzes the host placement of the instance. Store the EC2 instance ID of noncompliant resources in an Amazon RDS for MySQL DB instance. Generate a report by querying the RDS instance and exporting the query results to a CSV text file.

Answer:

Explanation:

The correct answer is C. Using AWS Config to identify and audit all EC2 instances based on their host placement configuration is the most efficient and scalable solution to ensure compliance with the software licensing requirement. AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources. By creating a custom AWS Config rule that triggers a Lambda function to verify host placement, the DevOps engineer can automate the process of checking whether the instances are running on EC2 Dedicated Hosts or not. The Lambda function can return a NON_COMPLIANT result if the instance is not running on an EC2 Dedicated Host, and the AWS Config report can provide a summary of the compliance status of the instances. This solution requires the least administrative overhead compared to the other options.

Option A is incorrect because using AWS Systems Manager Configuration Compliance to scan and build a database of noncompliant EC2 instances based on their host placement configuration is a more complex and costly solution than using AWS Config. AWS Systems Manager Configuration Compliance is a feature of AWS Systems Manager that enables you to scan your managed instances for patch compliance and configuration inconsistencies. To use this feature, the DevOps engineer would need to install the Systems Manager Agent on each EC2 instance, create a State Manager association to run the put-compliance-items API action periodically, and use a DynamoDB table to store the instance IDs of noncompliant resources. This solution would also require more API calls and storage costs than using AWS Config.

Option B is incorrect because using custom Java code running on an EC2 instance to check and terminate noncompliant EC2 instances is a more cumbersome and error-prone solution than using AWS Config. This solution would require the DevOps engineer to write and maintain the Java code, set up EC2 Auto Scaling for the instance, use an SQS queue and another worker instance to process the instance IDs, use a Lambda function and an SNS topic to terminate and notify the noncompliant instances, and handle any potential failures or exceptions in the workflow. This solution would also incur more compute, storage, and messaging costs than using AWS Config.

Option D is incorrect because using AWS CloudTrail to identify and audit EC2 instances by analyzing the EC2 RunCommand API action is a less reliable and accurate solution than using AWS Config. AWS CloudTrail is a service that enables you to monitor and log the API activity in your AWS account. The EC2 RunCommand API action is used to execute commands on one or more EC2 instances. However, this API action does not necessarily indicate the host placement of the instance, and it may not capture all the instances that are running on EC2 Dedicated Hosts or not. Therefore, option D would not provide a comprehensive and consistent audit of the EC2 instances.

Question # 125

A company ' s application development team uses Linux-based Amazon EC2 instances as bastion hosts. Inbound SSH access to the bastion hosts is restricted to specific IP addresses, as defined in the associated security groups. The company ' s security team wants to receive a notification if the security group rules are modified to allow SSH access from any IP address.

What should a DevOps engineer do to meet this requirement?

Create an Amazon EventBridge rule with a source of aws.cloudtrail and the event name AuthorizeSecurityGroupIngress. Define an Amazon Simple Notification Service (Amazon SNS) topic as the target.

Enable Amazon GuardDuty and check the findings for security groups in AWS Security Hub. Configure an Amazon EventBridge rule with a custom pattern that matches GuardDuty events with an output of NON_COMPLIANT. Define an Amazon Simple Notification Service (Amazon SNS) topic as the target.

Create an AWS Config rule by using the restricted-ssh managed rule to check whether security groups disallow unrestricted incoming SSH traffic. Configure automatic remediation to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic.

Enable Amazon Inspector. Include the Common Vulnerabilities and Exposures-1.1 rules package to check the security groups that are associated with the bastion hosts. Configure Amazon Inspector to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic.
