AWS DevOps Container Services 4

Question 1

Which AWS service provides a managed Kubernetes experience and handles control plane upgrades and patching automatically?

Accepted Answer

Amazon EKS

Answer

Amazon EKS is a fully managed Kubernetes service where AWS operates and upgrades the control plane, including API servers and etcd.

Question 2

A CI/CD pipeline builds a Docker image and must push it to ECR. After running 'docker build', what is the correct sequence of AWS CLI steps?

Accepted Answer

aws ecr get-login-password | docker login → docker tag → docker push

Answer

You must authenticate Docker to ECR using get-login-password piped to docker login, then tag the image with the ECR URI, then push it.

Question 3

What is the function of a Kubernetes Ingress resource in an EKS cluster?

Accepted Answer

It manages external HTTP/HTTPS access to services within the cluster

Answer

An Ingress resource configures an Ingress controller (e.g., AWS Load Balancer Controller) to route external HTTP/HTTPS traffic to internal Kubernetes services.

Question 4

Which ECS feature allows you to define CPU and memory at the task level and override them per container?

Accepted Answer

Task-level and container-level resource limits in the task definition

Answer

ECS task definitions support task-level CPU/memory (required for Fargate) and optional per-container limits that cannot exceed the task-level allocation.

Question 5

In a CodePipeline deploying to EKS, which action would apply a Kubernetes manifest stored in S3 to the cluster?

Accepted Answer

Use an AWS Lambda action that runs kubectl apply

Answer

Since CodePipeline has no native EKS action, a Lambda function (or CodeBuild step) running kubectl apply is the standard pattern for deploying Kubernetes manifests.
