A company is developing a microservices-based application on AWS. The application consists of AWS Lambda functions and Amazon Elastic Container Service (Amazon ECS) services that need to be deployed frequently.

A DevOps engineer needs to implement a consistent deployment solution across all components of the application. The solution must automate the deployments, minimize downtime during updates, and manage configuration data for the application.

Which solution will meet these requirements with the LEAST deployment effort?

A.

Use AWS CloudFormation to define and provision the Lambda functions and ECS services. Implement stack updates with resource replacement for all components. Use AWS Secrets Manager to manage the configuration data.

B.

Use AWS CodeDeploy to manage deployments for the Lambda functions and ECS services. Implement canary deployments for the Lambda functions. Implement blue/green deployments for the ECS services. Use AWS Systems Manager Parameter Store to manage the configuration data.

C.

Use AWS Step Functions to orchestrate deployments for the Lambda functions and ECS services. Use canary deployments for the Lambda functions and ECS services in a different AWS Region. Use AWS Systems Manager Parameter Store to manage the configuration data.

D.

Use AWS Systems Manager to manage deployments for the Lambda functions and ECS services. Implement all-at-once deployments for the Lambda functions. Implement rolling updates for the ECS services. Use AWS Secrets Manager to manage the configuration data.

A company uses an organization in AWS Organizations that has all features enabled. The company uses AWS Backup in a primary account and uses an AWS Key Management Service (AWS KMS) key to encrypt the backups.

The company needs to automate a cross-account backup of the resources that AWS Backup backs up in the primary account. The company configures cross-account backup in the Organizations management account. The company creates a new AWS account in the organization and configures an AWS Backup backup vault in the new account. The company creates a KMS key in the new account to encrypt the backups. Finally, the company configures a new backup plan in the primary account. The destination for the new backup plan is the backup vault in the new account.

When the AWS Backup job in the primary account is invoked, the job creates backups in the primary account. However, the backups are not copied to the new account's backup vault.

Which combination of steps must the company take so that backups can be copied to the new account's backup vault? (Select TWO.)

A.

Edit the backup vault access policy in the new account to allow access to the primary account.

B.

Edit the backup vault access policy in the primary account to allow access to the new account.

C.

Edit the backup vault access policy in the primary account to allow access to the KMS key in the new account.

D.

Edit the key policy of the KMS key in the primary account to share the key with the new account.

E.

Edit the key policy of the KMS key in the new account to share the key with the primary account.

A company uses AWS CodePipeline pipelines to automate releases of its application A typical pipeline consists of three stages build, test, and deployment.

A company has developed a web application that conducts seasonal sales on public holidays. The web application is deployed on AWS and uses AWS services for storage, database, computing, and encryption. During seasonal sales, the company expects high network traffic from many users. The company must receive insights regarding any unexpected behavior during the sale. A DevOps team wants to review the insights upon detecting anomalous behaviors during the sale.

A company runs an application on Amazon EC2 instances. The company uses a series of AWS CloudFormation stacks to define the application resources. A developer performs updates by building and testing the application on a laptop and then uploading the build output and CloudFormation stack templates to Amazon S3. The developer's peers review the changes before the developer performs the CloudFormation stack update and installs a new version of the application onto the EC2 instances.

The deployment process is prone to errors and is time-consuming when the developer updates each EC2 instance with the new application. The company wants to automate as much of the application deployment process as possible while retaining a final manual approval step before the modification of the application or resources.

The company already has moved the source code for the application and the CloudFormation templates to AWS CodeCommit. The company also has created an AWS CodeBuild project to build and test the application.

Which combination of steps will meet the company’s requirements? (Choose two.)

A.

Create an application group and a deployment group in AWS CodeDeploy. Install the CodeDeploy agent on the EC2 instances.

B.

Create an application revision and a deployment group in AWS CodeDeploy. Create an environment in CodeDeploy. Register the EC2 instances to the CodeDeploy environment.

C.

Use AWS CodePipeline to invoke the CodeBuild job, run the CloudFormation update, and pause for a manual approval step. After approval, start the AWS CodeDeploy deployment.

D.

Use AWS CodePipeline to invoke the CodeBuild job, create CloudFormation change sets for each of the application stacks, and pause for a manual approval step. After approval, run the CloudFormation change sets and start the AWS CodeDeploy deployment.

E.

Use AWS CodePipeline to invoke the CodeBuild job, create CloudFormation change sets for each of the application stacks, and pause for a manual approval step. After approval, start the AWS CodeDeploy deployment.

A company has an AWS Cloud Format ion slack that is deployed in a single AWS account. The company has configured the stack to send event notifications to an Amazon Simple Notification Service (Amazon SNS) topic.

A DevOps engineer must implement an automated solution that applies a tag to the specific Cloud Formation stack instance only after a successful stack update occurs. The DevOps engineer has created an AWS Lambda function that applies and updates this tag (or the specific slack instance.

Which solution will meet these requirements?

A.

Run the AWS-UpdateCloudfomationStack AWS Systems Manager Automation runbook when Systems Manager detects an UPDATE_COMPLETE event for the instance status of the Cloud Formation stack. Configure the runbook to invoke the Lambda function.

B.

C.

Create an Amazon EventBridge rule that matches the UPDATE COMPLETE event pattern for the instance status of the CloudFormation stack. Configure the rule to invoke the Lambda function.

D.

Adjust the configuration of the CloudFormation stack to send notifications for only an UPDATE COMPLETE instance status event to the SNS topic. Subscribe the Lambda function to the SNS topic.
