Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q234-Q239):

NEW QUESTION # 234
A company uses an organization in AWS Organizations to manage multiple AWS accounts in a hierarchical structure. An SCP that is associated with the organization root allows IAM users to be created.
A DevOps team must be able to create IAM users with any level of permissions. Developers must also be able to create IAM users. However, developers must not be able to grant new IAM users excessive permissions. The developers have the CreateAndManageUsers role in each account. The DevOps team must be able to prevent other users from creating IAM users.
Which combination of steps will meet these requirements? (Select TWO.)

A. Create an IAM permissions policy named DeveloperBoundary within each account. Configure the DeveloperBoundary policy to allow developers to create IAM users and to assign policies to IAM users only if the developer includes the PermissionBoundaries policy as the permissions boundary. Attach the DeveloperBoundary policy to the CreateAndManageUsers role within each account.
B. Create an IAM permissions policy named PermissionBoundaries within each account. Configure PermissionsBoundaries to allow users who have the PermissionBoundaries policy to create new IAM users.
C. Create an IAM permissions policy named PermissionBoundaries within each account. Configure the PermissionBoundaries policy to specify the maximum permissions that a developer can grant to a new IAM user.
D. Create an SCP in the organization to grant users that have the DeveloperBoundary policy attached the ability to create new IAM users and to modify IAM users. Configure the SCP to require users to attach the PermissionBoundaries policy to any new IAM user. Attach the SCP to the root of the organization.
E. Create an SCP in the organization to deny users the ability to create and modify IAM users. Attach the SCP to the root of the organization. Attach the CreateAndManageUsers role to developers.

Answer: A,C

Explanation:
Comprehensive & Detailed Explanation (150-250 words):
To allow developers to create IAM users without granting excessive permissions, the correct solution is to use permissions boundaries, which AWS specifically recommends for restricting delegated administrators such as developers. A permissions boundary defines the maximum permissions that an IAM user or role can delegate.
Step C ensures that each AWS account contains a PermissionBoundaries policy defining the maximum allowed permissions that any developer-created user may receive. This prevents privilege escalation, even if the developer attaches a more powerful policy. This aligns with AWS guidance for restricting privilege escalation within multi-account environments.
Step E ensures that developers can create IAM users but only if they attach the PermissionBoundaries policy as the permissions boundary. By attaching the DeveloperBoundary policy to the CreateAndManageUsers role, developers gain the ability to create users, but they are cryptographically prevented from assigning permissions outside the boundary policy.
Meanwhile, the DevOps team (who are not restricted by the boundary) can still create IAM users with full permissions.
This combination satisfies all constraints:
DevOps team: unrestricted IAM creation
Developers: restricted IAM creation enforced by boundaries
Other users: still blocked from IAM creation by existing SCP

NEW QUESTION # 235
A company manages environments for its application in multiple AWS accounts. Each environment account is in a different OU in AWS Organizations.
A DevOps team is responsible for the application deployment process across the environments. The deployment process uses an AWS CodePipeline pipeline in a Shared Services account. The DevOps team members are in the same user group. The team members have administrative access to all accounts through AWS IAM Identity Center.
A recent deployment problem in the development environment required the DevOps team to perform manual steps. The deployment to the production environment then resulted in an incident that caused the pipeline to fail, blocking new deployments for several hours.
A DevOps engineer needs to ensure that only the pipeline can perform deployments in the production environment. The DevOps engineer must have access to the environment in case of an emergency.
Which solution will meet these requirements with the MOST operational efficiency?

A. Create an SCP that denies all write actions for the DevOps team members on the production OU. Use a specific tag to tag the resources that CodePipeline provisions. Add an SCP that denies modification of tagged resources by any entity other than the DevOps engineer.
B. Update the DevOps group to be able to assume the pipeline role for the production accounts. Configure a new user in IAM Identity Center for the DevOps engineer with a new permission set that has AdministratorAccess permissions. Add an SCP that denies modification of resources by any entity other than the DevOps engineer.
C. Create an SCP that denies all write actions for the DevOps team members on the production OU.
Configure a new user in IAM Identity Center for the DevOps engineer with a new permission set that has AdministratorAccess permissions. Add an SCP that denies modification of resources by any entity other than the pipeline role.
D. Update the DevOps group to have the ReadOnlyAccess permission set for the production accounts.
Configure the DevOps engineer user with a new permission set that has AdministratorAccess permissions and that allows the user to assume the pipeline role. Add an SCP that denies modification of resources by any entity other than the pipeline role.

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The requirement is to restrict production deployments strictly to the pipeline, while still allowing emergency access to a specific engineer.
* The best approach is to restrict the DevOps team toread-only accessin production accounts, minimizing risk of manual changes (Option A).
* The DevOps engineer can have an admin permission set but assume thepipeline IAM rolefor deployment, enforcing strict control.
* Applying an SCP todeny modification by anyone other than the pipeline roleenforces this at the organization level.Option B is similar but unnecessarily creates separate IAM users, increasing management overhead. Option C grants the DevOps engineer broader permissions that may conflict with controls. Option D complicates management with tagging and SCPs, increasing operational overhead.
Reference:
AWS Organizations Service Control Policies (SCPs):"SCPs can restrict what actions identities in member accounts can perform, even for administrators."(AWS Organizations SCP Documentation) IAM Identity Center Role Assumption Best Practices:"Use role assumption for limited elevated permissions instead of broad admin access."(AWS IAM Best Practices)

NEW QUESTION # 236
A DevOps engineer maintains a web application that is deployed on an Amazon Elastic Container Service (Amazon ECS) service behind an Application Load Balancer (ALB).
Recent updates to the service caused downtime for the application because of issues with the application code.
The DevOps engineer needs to design a solution to test updates on a small amount of traffic first before deploying to the rest of the service.
Which solution will meet these requirements?

A. Create a new pipeline in AWS CodePipeline. Connect the pipeline to an AWS CodeConnections compatible Git repository. Configure the pipeline with an ECRBuildAndPublish action and an Amazon ECS standard deployment action. Configure the ECS service to use the rolling update deployment type.
B. Update the ECS service to use AWS CodeDeploy as the deployment controller. Create a second target group for the ALB. Create a CodeDeploy application and deployment group for the application. Use CodeDeploy to deploy updates by using the CodeDeployDefault.ECSCanary10Percent15Minutes deployment configuration.
C. Create a new AWS CodeBuild project. Connect the project to an AWS CodeConnections compatible Git repository. Create a buildspec.yml file in the Git repository that contains commands to call the Amazon ECS UpdateService API. Set a slow start duration of 2 minutes on the ALB target group.
D. Create a new AWS CodeBuild project that uses AWS Lambda compute and that includes an IAM role that has permissions to update the ECS task definition. Update the project buildspec file to call the Amazon ECS RegisterTaskDefinition API for deployments. Configure the ECS service to use the rolling update deployment type.

Answer: B

Explanation:
The key requirement is to shift a small percentage of traffic to a new version first to validate changes before rolling out to the entire ECS service, thereby reducing downtime and deployment risk. For ECS services behind an Application Load Balancer, the AWS-recommended and most reliable approach is to use AWS CodeDeploy with blue/green or canary deployments.
Option B directly addresses this requirement. By configuring the ECS service to use CodeDeploy as the deployment controller, CodeDeploy can manage traffic shifting between two ALB target groups: one for the current (stable) version and one for the new version. The CodeDeployDefault.
ECSCanary10Percent15Minutes deployment configuration initially routes 10% of production traffic to the new task set, monitors the deployment for issues, and then shifts the remaining traffic after the defined interval. This enables early detection of application errors while limiting user impact.
Option A and C rely on rolling updates, which replace tasks incrementally but do not provide precise traffic control or automated rollback based on health checks. Option D's slow start setting only affects how quickly targets receive traffic after registration and does not implement true canary testing.
Therefore, using AWS CodeDeploy with ECS canary deployments is the most robust, AWS-supported solution to test changes safely before full rollout.

NEW QUESTION # 237
A company runs applications in AWS accounts that are in an organization in AWS Organizations The applications use Amazon EC2 instances and Amazon S3.
The company wants to detect potentially compromised EC2 instances suspicious network activity and unusual API activity in its existing AWS accounts and in any AWS accounts that the company creates in the future When the company detects one to these events the company wants to use an existing Amazon Simple Notification Service (Amazon SNS) topic to send a notification to its operational support team for investigation and remediation.
Which solution will meet these requirements in accordance with AWS best practices?

A. In the organization's management account configure Amazon GuardDuty to add newly created AWS accounts by invitation and to send invitations to the existing AWS accounts Create an AWS Cloud Formation stack set that accepts the GuardDuty invitation and creates an Amazon EventBridge rule Configure the rule with an event pattern to match. GuardDuty events and to forward matching events to the SNS topic. Configure the Cloud Formation stack set to deploy into all AWS accounts in the organization.
B. In the organization's management account configure an AWS account as the AWS CloudTrail administrator account in the CloudTrail administrator account create a CloudTrail organization trail.
Add the company's existing AWS accounts to the organization trail Create an SCP that enables VPC Flow Logs in each account in the organization. Configure AWS Security Hub for the organization.Create an Amazon EventBridge rule with an event pattern to match Security Hub events and to forward matching events to the SNS topic.
C. In the organization's management account configure an AWS account as the Amazon GuardDuty administrator account. In the GuardDuty administrator account add the company's existing AWS accounts to GuardDuty as members In the GuardDuty administrator account create an Amazon EventBridge rule with an event pattern to match GuardDuty events and to forward matching events to the SNS topic.
D. In the organization's management account. create an AWS CloudTrail organization trail Activate the organization trail in all AWS accounts in the organization. Create an SCP that enables VPC Flow Logs in each account in the organization. Configure AWS Security Hub for the organization Create an Amazon EventBridge rule with an even pattern to match Security Hub events and to forward matching events to the SNS topic.

Answer: A

Explanation:
Explanation
It allows the company to detect potentially compromised EC2 instances, suspicious network activity, and unusual API activity in its existing AWS accounts and in any AWS accounts that the company creates in the future using Amazon GuardDuty. It also provides a solution for automatically adding future AWS accounts to GuardDuty by configuring GuardDuty to add newly created AWS accounts by invitation and to send invitations to the existing AWS accounts.

NEW QUESTION # 238
A company uses AWS Organizations to manage multiple accounts. Information security policies require that all unencrypted Amazon EBS volumes be marked as non-compliant. A DevOps engineer needs to automatically deploy the solution and ensure that this compliance check is always present.
Which solution will accomplish this?

A. Create an AWS CloudFormation template that defines an AWS Inspector rule to check whether EBS encryption is enabled. Save the template to an Amazon S3 bucket that has been shared with all accounts within the company. Update the account creation script pointing to the CloudFormation template in Amazon S3.
B. Create an SCP in Organizations. Set the policy to prevent the launch of Amazon EC2 instances without encryption on the EBS volumes using a conditional expression. Apply the SCP to all AWS accounts. Use Amazon Athena to analyze the AWS CloudTrail output, looking for events that deny an ec2:RunInstances action.
C. Deploy an IAM role to all accounts from a single trusted account. Build a pipeline with AWS CodePipeline with a stage in AWS Lambda to assume the IAM role, and list all EBS volumes in the account. Publish a report to Amazon S3.
D. Create an AWS Config organizational rule to check whether EBS encryption is enabled and deploy the rule using the AWS CLI. Create and apply an SCP to prohibit stopping and deleting AWS Config across the organization.

Answer: D
