B : Update the resource-based policy of the default event bus in each account to allow the DevOps account to receive events. Configure an EventBridge rule in the DevOps account that matches Amazon Connect events and has a target of the default event bus in the other accounts.

C : Update the resource-based policy of the default event bus in the DevOps account. Update the policy to allow events to be received from the accounts. Configure an EventBridge rule in each account that matches Amazon Connect events and has a target of the DevOps account's default event bus

D : Update the resource-based policy of the default event bus in the DevOps account. Update the policy to allow events to be replayed by the accounts. Configure an EventBridge rule in each account that matches Amazon Connect events and has a target of the DevOps account's default event bus.

Answer: C

Question 2

An insurance firm has recently undergone digital transformation and AWS cloud adoption. Its app development team has four environments, namely DEV, TEST, PRE-PROD, and PROD, for its flagship application that is configured with AWS CodePipeline. After several weeks, they noticed that there were several outages caused by misconfigured files or faulty code blocks that were deployed into the PROD environment. A DevOps Engineer has been assigned to add the required steps to identify issues in the application before it is released.

Which of the following is the MOST appropriate combination of steps that the Engineer should implement to identify functional issues during the deployment process? (Select TWO.)

A : the pipeline, add an AWS CodeDeploy action to deploy the latest version of the application to the PRE-PROD environment. Set up a manual approval action in the pipeline so that the QA team can perform the required tests. Add another CodeDeploy action that deploys the verified code to the PROD environment after the manual approval action.

B : grate the pipeline from CodePipeline to AWS Data Pipeline to enable more CI/CD features. Add a test action that uses Amazon Macie to the pipeline. Run an assessment using the Runtime Behavior Analysis rules package to verify that the deployed code complies with the strict security standards of the company before deploying it to the PROD environment.

C : Add a test action that uses Amazon GuardDuty to the pipeline. Run an assessment using the Runtime Behavior Analysis rules package to verify that the deployed code complies with the strict security standards of the company before deploying it to the PROD environment.

D : a test action to the pipeline to run both the unit and functional tests using AWS CodeBuild. Verify that the test results passed before deploying the new application revision to the PROD environment.

E : a test action that uses Amazon Inspector to the pipeline. Run an assessment using the Runtime Behavior Analysis rules package to verify that the deployed code complies with the strict security standards of the company before deploying it to the PROD environment.

Answer: A,D

Question 3

A company is developing a serverless application that uses AWS Lambda, AWS SAM, and Amazon API Gateway. There is a requirement to fully automate the backend Lambda deployment in such a way that the deployment will automatically run whenever a new commit is pushed to an AWS CodeCommit repository. There should also be a separate environment pipeline for TEST and PROD environments. In addition, the TEST environment should be the only one that allows automatic deployment.

As a DevOps Engineer, who can you satisfy these requirements?

A : t up two pipelines using AWS CodePipeline for TEST and PROD environments. On both pipelines, set up a manual approval step for application deployment. Set up separate CodeCommit repositories for each environment and configure each pipeline to retrieve the source code from CodeCommit. Deploy the Lambda functions with AWS CloudFormation by setting up a deployment step in the pipeline.

B : t up two pipelines using AWS CodePipeline for TEST and PROD environments. Configure the PROD pipeline to have a manual approval step. Create a CodeCommit repository with a branch for each environment and configure the pipeline to retrieve the source code from CodeCommit according to its branch. Deploy the Lambda functions with AWS CloudFormation by setting up a deployment step in the pipeline.

C : t up two pipelines using AWS CodePipeline for TEST and PROD environments. In the PROD pipeline, set up a manual approval step for application deployment. Set up separate CodeCommit repositories for each environment and configure each pipeline to retrieve the source code from CodeCommit. Deploy the Lambda functions with AWS CloudFormation by setting up a deployment step in the pipeline.

D : eate a new pipeline using AWS CodePipeline and a new CodeCommit repository for each environment. Configure CodePipeline to retrieve the application source code from the appropriate repository. Deploy the Lambda functions with AWS CloudFormation by creating a deployment step in the pipeline.

Answer: B

Question 4

The company's DevOps engineer discovered that the errors were caused by RDS connection limits being reached. The DevOps engineer also discovered that more than 90% of the API requests are GET requests that read from the DB cluster. How should the DevOps engineer solve this problem with the LEAST development effort?

A : Migrate from Amazon RDS to Amazon DynamoDB. Add an Amazon CloudFront distribution in front of the API Gateway REST API.

B : Add a proxy from Amazon RDS Proxy in front of the RDS DB cluster. Enable API caching in API Gateway.

C : Add an Amazon RDS Proxy in front of the RDS database cluster. Provision an Amazon ElastiCache (Redis OSS) cluster.

D : Migrate from Amazon RDS to Amazon DynamoDB. Enable API caching in API Gateway.

Answer: B

Question 5

A leading game development company is planning to host its latest video game on AWS. It is expected that there will be millions of users around the globe that will play the game. The architecture should allow players to send or receive data on the backend in real-time for a better gaming experience. The application libraries and user data of the game must also comply with the data residency requirement wherein all files must remain in the same region. CodeCommit, CodeBuild, CodeDeploy, and CodePipeline should be utilized to build the CI/CD process.

As a DevOps Engineer, which of the following is the MOST suitable and efficient solution that you should implement to satisfy this requirement?

A : eate a new pipeline using AWS CodePipeline and a CodeCommit repository as the source on multiple AWS regions. Configure the repository of the pipeline for each region to trigger the build and deployment actions whenever there is a new code update. The pipeline will automatically store output files on a default artifact bucket on each region.

B : eate a new pipeline using AWS CodePipeline and a CodeCommit repository as the source in your primary AWS region. Set a CodeBuild test action to run the automated unit and integration tests. Configure the repository to trigger the build and deployment actions whenever there is a new code update. Using the AWS Management Console, set up the pipeline to use cross-region actions that will run the build and deployment actions to other regions. Manually configure the pipeline to automatically store output files on a single S3 bucket.

C : eate a new pipeline using AWS CodePipeline and a CodeCommit repository as the source in your primary AWS region. Configure the repository to trigger the build and deployment actions whenever there is a new code update. Using the AWS Management Console, set up the pipeline to use cross-region actions that will run the build and deployment actions to other regions. The pipeline will automatically store output files on a default artifact bucket on each region.

D : eate a new pipeline using AWS CodePipeline and a CodeCommit repository as the source in your primary AWS region. Configure the repository to trigger the build and deployment actions whenever there is a new code update. Using the AWS Management Console, set up the pipeline to use cross-AZ actions that will run the build and deployment actions to other Availability Zones. The pipeline will automatically store output files on a default artifact bucket on each AZ.
