A company is building a new pipeline by using AWS CodePipeline and AWS CodeBuild in a build account. The pipeline consists of two stages. The first stage is a CodeBuild job to build and package an AWS Lambda function. The second stage consists of deployment actions that operate on two different AWS accounts: a development environment account and a production environment account. The deployment stages use the AWS CloudFormation action that CodePipeline invokes to deploy the infrastructure that the Lambda function requires. A DevOps engineer creates the CodePipeline pipeline and configures the pipeline to encrypt build artifacts by using the AWS Key Management Service (AWS KMS) AWS managed key for Amazon S3 (the aws/s3 key). The artifacts are stored in an S3 bucket. When the pipeline runs, the CloudFormation actions fail with an access denied error. Which combination of actions must the DevOps engineer perform to resolve this error? (Choose two.)

A company is using an organization in AWS Organizations to manage multiple AWS accounts. The company’s development team wants to use AWS Lambda functions to meet resiliency requirements and is rewriting all applications to work with Lambda functions that are deployed in a VPC. The development team is using Amazon Elastic File System (Amazon EFS) as shared storage in Account A in the organization. The company wants to continue to use Amazon EFS with Lambda. Company policy requires all serverless projects to be deployed in Account B. A DevOps engineer needs to reconfigure an existing EFS file system to allow Lambda functions to access the data through an existing EFS access point. Which combination of steps should the DevOps engineer take to meet these requirements? (Choose three.)

A media company has several thousand Amazon EC2 instances in an AWS account. The company is using Slack and a shared email inbox for team communications and important updates. A DevOps engineer needs to send all AWS-scheduled EC2 maintenance notifications to the Slack channel and the shared inbox. The solution must include the instances’ Name and Owner tags. Which solution will meet these requirements?

An AWS CodePipeline pipeline has implemented a code release process. The pipeline is integrated with AWS CodeDeploy to deploy versions of an application to multiple Amazon EC2 instances for each CodePipeline stage. During a recent deployment, the pipeline failed due to a CodeDeploy issue. The DevOps team wants to improve monitoring and notifications during deployment to decrease resolution times. What should the DevOps engineer do to create notifications when issues are discovered?

A global company manages multiple AWS accounts by using AWS Control Tower. The company hosts internal applications and public applications. Each application team in the company has its own AWS account for application hosting. The accounts are consolidated in an organization in AWS Organizations. One of the AWS Control Tower member accounts serves as a centralized DevOps account with CI/CD pipelines that application teams use to deploy applications to their respective target AWS accounts. An IAM role for deployment exists in the centralized DevOps account. An application team is attempting to deploy its application to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster in an application AWS account. An IAM role for deployment exists in the application AWS account. The deployment is through an AWS CodeBuild project that is set up in the centralized DevOps account. The CodeBuild project uses an IAM service role for CodeBuild. The deployment is failing with an Unauthorized error during attempts to connect to the cross-account EKS cluster from CodeBuild. Which solution will resolve this error?

A highly regulated company has a policy that DevOps engineers should not log in to their Amazon EC2 instances except in emergencies. If a DevOps engineer does log in, the security team must be notified within 15 minutes of the occurrence. Which solution will meet these requirements?

A company updated the AWS CloudFormation template for a critical business application. The stack update process failed due to an error in the updated template, and AWS CloudFormation automatically began the stack rollback process. Later, a DevOps engineer discovered that the application was still unavailable and that the stack was in the UPDATE_ROLLBACK_FAILED state. Which combination of actions should the DevOps engineer perform so that the stack rollback can complete successfully? (Choose two.)

A development team manually builds an artifact locally and then places it in an Amazon S3 bucket. The application has a local cache that must be cleared when a deployment occurs. The team runs a command to do this, downloads the artifact from Amazon S3, and unzips the artifact to complete the deployment. A DevOps team wants to migrate to a CI/CD process and build in checks to stop and roll back the deployment when a failure occurs. This requires the team to track the progression of the deployment. Which combination of actions will accomplish this? (Choose three.)

A DevOps engineer is working on a project that is hosted on Amazon Linux and has failed a security review. The DevOps manager has been asked to review the company buildspec.yaml file for an AWS CodeBuild project and provide recommendations. The buildspec.yaml file is configured as follows: What changes should be recommended to comply with AWS security best practices? (Choose three.)

A company has a legacy application. A DevOps engineer needs to automate the process of building the deployable artifact for the legacy application. The solution must store the deployable artifact in an existing Amazon S3 bucket for future deployments to reference. Which solution will meet these requirements in the MOST operationally efficient way?

A company builds a container image in an AWS CodeBuild project by running Docker commands. After the container image is built, the CodeBuild project uploads the container image to an Amazon S3 bucket. The CodeBuild project has an IAM service role that has permissions to access the S3 bucket. A DevOps engineer needs to replace the S3 bucket with an Amazon Elastic Container Registry (Amazon ECR) repository to store the container images. The DevOps engineer creates an ECR private image repository in the same AWS Region of the CodeBuild project. The DevOps engineer adjusts the IAM service role with the permissions that are necessary to work with the new ECR repository. The DevOps engineer also places new repository information into the docker build command and the docker push command that are used in the buildspec.yml file. When the CodeBuild project runs a build job, the job fails when the job tries to access the ECR repository. Which solution will resolve the issue of failed access to the ECR repository?

A company manually provisions IAM access for its employees. The company wants to replace the manual process with an automated process. The company has an existing Active Directory system configured with an external SAML 2.0 identity provider (IdP). The company wants employees to use their existing corporate credentials to access AWS. The groups from the existing Active Directory system must be available for permission management in AWS Identity and Access Management (IAM). A DevOps engineer has completed the initial configuration of AWS IAM Identity Center (AWS Single Sign-On) in the company’s AWS account. What should the DevOps engineer do next to meet the requirements?

A company is using AWS to run digital workloads. Each application team in the company has its own AWS account for application hosting. The accounts are consolidated in an organization in AWS Organizations. The company wants to enforce security standards across the entire organization. To avoid noncompliance because of security misconfiguration, the company has enforced the use of AWS CloudFormation. A production support team can modify resources in the production environment by using the AWS Management Console to troubleshoot and resolve application-related issues. A DevOps engineer must implement a solution to identify in near real time any AWS service misconfiguration that results in noncompliance. The solution must automatically remediate the issue within 15 minutes of identification. The solution also must track noncompliant resources and events in a centralized dashboard with accurate timestamps. Which solution will meet these requirements with the LEAST development overhead?

A company uses AWS Organizations to manage its AWS accounts. The organization root has an OU that is named Environments. The Environments OU has two child OUs that are named Development and Production, respectively. The Environments OU and the child OUs have the default FullAWSAccess policy in place. A DevOps engineer plans to remove the FullAWSAccess policy from the Development OU and replace the policy with a policy that allows all actions on Amazon EC2 resources. What will be the outcome of this policy replacement?

A company is examining its disaster recovery capability and wants the ability to switch over its daily operations to a secondary AWS Region. The company uses AWS CodeCommit as a source control tool in the primary Region. A DevOps engineer must provide the capability for the company to develop code in the secondary Region. If the company needs to use the secondary Region, developers can add an additional remote URL to their local Git configuration. Which solution will meet these requirements?

A DevOps team is merging code revisions for an application that uses an Amazon RDS Multi-AZ DB cluster for its production database. The DevOps team uses continuous integration to periodically verify that the application works. The DevOps team needs to test the changes before the changes are deployed to the production database. Which solution will meet these requirements?

A company manages a multi-tenant environment in its VPC and has configured Amazon GuardDuty for the corresponding AWS account. The company sends all GuardDuty findings to AWS Security Hub. Traffic from suspicious sources is generating a large number of findings. A DevOps engineer needs to implement a solution to automatically deny traffic across the entire VPC when GuardDuty discovers a new suspicious source. Which solution will meet these requirements?

A company uses AWS Secrets Manager to store a set of sensitive API keys that an AWS Lambda function uses. When the Lambda function is invoked the Lambda function retrieves the API keys and makes an API call to an external service. The Secrets Manager secret is encrypted with the default AWS Key Management Service (AWS KMS) key. A DevOps engineer needs to update the infrastructure to ensure that only the Lambda function’s execution role can access the values in Secrets Manager. The solution must apply the principle of least privilege. Which combination of steps will meet these requirements? (Choose two.)

A company's DevOps engineer is creating an AWS Lambda function to process notifications from an Amazon Simple Notification Service (Amazon SNS) topic. The Lambda function will process the notification messages and will write the contents of the notification messages to an Amazon RDS Multi-AZ DB instance. During testing, a database administrator accidentally shut down the DB instance. While the database was down the company lost several of the SNS notification messages that were delivered during that time. The DevOps engineer needs to prevent the loss of notification messages in the future. Which solutions will meet this requirement? (Choose two.)

A company has an application that runs on Amazon EC2 instances. The company uses an AWS CodePipeline pipeline to deploy the application into multiple AWS Regions. The pipeline is configured with a stage for each Region. Each stage contains an AWS CloudFormation action for each Region. When the pipeline deploys the application to a Region, the company wants to confirm that the application is in a healthy state before the pipeline moves on to the next Region. Amazon Route 53 record sets are configured for the application in each Region. A DevOps engineer creates a Route 53 health check that is based on an Amazon CloudWatch alarm for each Region where the application is deployed. What should the DevOps engineer do next to meet the requirements?
