Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q20-Q25):

NEW QUESTION # 20
A company runs an application that uses an Amazon S3 bucket to store images. A DevOps engineer needs to implement a multi-Region disaster recovery (DR) strategy for the S3 objects. The DevOps engineer enables two-way replication between the S3 buckets.
The company must be able to fail over to a second S3 bucket that is in a second AWS Region. When an image is added to either S3 bucket, the image must be replicated to the other S3 bucket within 15 minutes.
Which combination of steps will meet these requirements in the MOST operationally efficient way? (Select THREE.)

A. Enable S3 Transfer Acceleration on both S3 buckets.
B. Call the SubmitMultiRegionAccessPointRoutes operation in the Amazon S3 API when the company needs to fail over to the S3 bucket in the second Region.
C. Enable S3 Replication Time Control (S3 RTC) for each replication rule used in the configuration.
D. Configure a routing control in Amazon Route 53 Application Recovery Controller (ARC). Add both S3 buckets in an active-passive configuration.
E. Create an S3 Multi-Region Access Point in an active-passive configuration.
F. Use Amazon Route 53 Application Recovery Controller (ARC) to shift traffic from the primary bucket to the failover bucket in the second Region.

Answer: B,C,E

Explanation:
A (S3 RTC) is required to meet the "replicated within 15 minutes" requirement in a verifiable way. Replication Time Control is the S3 feature that provides a 15-minute replication time SLA for replicated objects (instead of "best effort" replication timing).
B (S3 Multi-Region Access Point, active-passive) provides the most operationally efficient failover approach. An MRAP gives you a single global access point for S3 across Regions and supports controlled routing to the chosen bucket, avoiding custom DNS logic per application/client.
C (SubmitMultiRegionAccessPointRoutes) is the mechanism to perform failover for an MRAP by changing which Regional bucket is routed for the Multi-Region Access Point. This gives an explicit, API-driven "fail over now" action aligned with active-passive routing.
Why the others aren't part of the "most operationally efficient" three:
D (Transfer Acceleration) optimizes upload/download performance over long distances, but it does not guarantee cross-Region replication within 15 minutes and doesn't provide failover control.

NEW QUESTION # 21
A company requires all employees to access secrets via Systems Manager Parameter Store with rotation every 60 days.
The company must add a new secret for an Amazon ElastiCache Redis cluster.
Which solution meets these requirements with the LEAST operational overhead?

A. Create the secret in Secrets Manager with Lambda rotation using Redis rotation template and 60-day schedule. Reference via Parameter Store path.
B. Create the secret in Secrets Manager with managed rotation (60 days). Reference via Parameter Store path.
C. Create the secret in Parameter Store and Lambda rotation (manual).
D. Create the secret in Parameter Store with automatic rotation (unsupported).

Answer: A

Explanation:
AWS Secrets Manager supports managed rotation using Lambda templates for ElastiCache (Redis). Secrets Manager can integrate with Parameter Store using references ({{resolve:secretsmanager:...}}). This ensures automatic rotation with minimal management.

NEW QUESTION # 22
A company's DevOps engineer uses AWS Systems Manager to perform maintenance tasks during maintenance windows. The company has a few Amazon EC2 instances that require a restart after notifications from AWS Health. The DevOps engineer needs to implement an automated solution to remediate these notifications. The DevOps engineer creates an Amazon EventBridge rule.
How should the DevOps engineer configure the EventBridge rule to meet these requirements?

A. Configure an event source of AWS Health, a service of EC2. and an event type that indicates instance maintenance. Target a Systems Manager document to restart the EC2 instance.
B. Configure an event source of Systems Manager and an event type that indicates a maintenance window. Target a Systems Manager document to restart the EC2 instance.
C. Configure an event source of EC2 and an event type that indicates instance maintenance. Target a newly created AWS Lambda function that registers an automation task to restart the EC2 instance during a maintenance window.
D. Configure an event source of AWS Health, a service of EC2, and an event type that indicates instance maintenance. Target a newly created AWS Lambda function that registers an automation task to restart the EC2 instance during a maintenance window.

Answer: A

NEW QUESTION # 23
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 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.
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 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.

Answer: B

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 # 24
A company is refactoring applications to use AWS. The company identifies an internal web application that needs to make Amazon S3 API calls in a specific AWS account.
The company wants to use its existing identity provider (IdP) auth.company.com for authentication. The IdP supports only OpenID Connect (OIDC). A DevOps engineer needs to secure the web application's access to the AWS account.
Which combination of steps will meet these requirements? (Select THREE.)

A. Configure AWS 1AM Identity Center. Configure an IdP. Upload the IdP metadata from the existing IdP.
B. Create an 1AM IdP by using the provider URL, audience, and signature from the existing IdP.
C. Create an 1AM role that has a policy that allows the necessary S3 actions. Configure the role's trust policy to allow the OIDC IdP to assume the role if the sts.amazon.conraud context key is appid from idp.
D. Configure the web application lo use the AssumeRoleWith Web Identity API operation to retrieve temporary credentials. Use the temporary credentials to make the S3 API calls.
E. Configure the web application to use the GetFederationToken API operation to retrieve temporary credentials Use the temporary credentials to make the S3 API calls.
F. Create an 1AM role that has a policy that allows the necessary S3 actions. Configure the role's trust policy to allow the OIDC IdP to assume the role if the auth.company.com:aud context key is appid_from_idp.

Answer: B,D,F

Explanation:
* Step 1: Creating an Identity Provider in IAMYou first need to configure AWS to trust the external identity provider (IdP), which in this case supports OpenID Connect (OIDC). The IdP will handle the authentication, and AWS will handle the authorization based on the IdP's token.
* Action:Create an IAM Identity Provider (IdP) in AWS using the existing provider's URL, audience, and signature. This step is essential for establishing trust between AWS and the external IdP.
* Why:This allows AWS to accept tokens from your external IdP (auth.company.com) for authentication.
