Question 1

A DevOps engineer needs to configure an AWS CodePipeline pipeline that publishes container images to an Amazon ECR repository. The pipeline must wait for the previous run to finish and must run when new Git tags are pushed to a Git repository connected to AWS CodeConnections. An existing deployment pipeline must run in response to new container image publications. Which solution will meet these requirements?

A : Configure a CodePipeline V2 type pipeline that uses QUEUED mode. Add a trigger filter to the pipeline definition that includes all tags. Configure an EventBridge rule that matches container image pushes to start the existing deployment pipeline.

B : Configure a CodePipeline V2 type pipeline that uses SUPERSEDED mode. Add a trigger filter to the pipeline definition that includes all branches. Configure an EventBridge rule that matches container image pushes to start the existing deployment pipeline.

C : Configure a CodePipeline V1 type pipeline that uses SUPERSEDED mode. Add a trigger filter to the pipeline definition that includes all tags. Add a stage at the end of the pipeline to invoke the existing deployment pipeline.

D : Configure a CodePipeline V1 type pipeline that uses QUEUED mode. Add a trigger filter to the pipeline definition that includes all branches. Add a stage at the end of the pipeline to invoke the existing deployment pipeline.

Answer: A

Question 2

A SaaS company uses ECS (Fargate) behind an ALB and CodePipeline + CodeDeploy for blue/green deployments. They need automatic, incremental traffic shifting over time with no downtime. Which solution will meet these requirements?

A : Use TimeBasedLinear in appspec.yaml with defined percentage and interval.

B : Use AllAtOnce deployment configuration.

C : Use TimeBasedCanary.

D : Configure weighted routing on ALB manually.

Answer: A

Question 3

A DevOps engineer is building the infrastructure for an application. The application needs to run on an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that includes Amazon EC2 instances. The EC2 instances need to use an Amazon Elastic File System (Amazon EFS) file system as a storage backend. The Amazon EFS Container Storage Interface (CSI) driver is installed on the EKS cluster.

When the DevOps engineer starts the application, the EC2 instances do not mount the EFS file system.

Which solutions will fix the problem? (Choose three.)

A : Switch the EKS nodes from Amazon EC2 to AWS Fargate.

B : Add an inbound rule to the EFS file system’s security group to allow NFS traffic from the EKS cluster.

C : Create an IAM role that allows the Amazon EFS CSI driver to interact with the file system

D : Set up AWS DataSync to configure file transfer between the EFS file system and the EKS nodes.

E : Create a mount target for the EFS file system in the subnet of the EKS nodes.

F : Disable encryption or the EFS file system.

Answer: B,C,F

Question 4

A DevOps engineer is supporting early-stage development for a developer platform running on Amazon EKS. Recently, the platform has experienced an increased rate of container restart failures. The DevOps engineer wants diagnostic information to isolate and resolve issues. Which solution will meet this requirement?

A : Configure CloudWatch dashboards using default EKS service metrics.

B : Configure AWS CloudTrail for the EKS cluster.

C : Configure CloudTrail Insights for the EKS cluster.

D : Configure Amazon CloudWatch Container Insights for the EKS cluster by enabling the CloudWatch Observability add-on.

Answer: D
