1. Which of the following Agile methodologies divides development into short cycles called sprints?

Waterfall

Kanban

Scrum

Extreme Programming (XP)

2. Your team follows a DevOps approach and has implemented a CI/CD pipeline. Recently, you noticed that deployments to production occasionally introduce critical bugs.

What is the BEST way to prevent these issues in the future?

Deploy manually instead of using automation

Implement automated testing (unit, integration, and regression tests) in the CI/CD pipeline

Increase the frequency of deployments to detect issues earlier

Require developers to manually test their code before pushing to production

3. You are working in an Agile development team using the Scrum framework. The team is facing difficulties completing sprint goals because requirements keep changing.

What is the BEST way to handle this situation?

Extend sprint durations to accommodate changing requirements

Cancel the sprint and start over with updated requirements

Educate stakeholders about Agile principles and work with them to define a clear Product Backlog

Move incomplete work to the next sprint without informing the Product Owner

4. A software development team is using Git for version control. A developer accidentally committed a secret API key to a public repository.

What is the BEST course of action to mitigate this security risk?

Use git revert to undo the commit

Immediately remove the key, force push the changes (git push --force), and update credentials

Add the API key to .gitignore and continue working

Use git stash to temporarily hide the key and restore it later

5. Your DevOps team is responsible for managing a CI/CD pipeline using Jenkins. After pushing new changes to the repository, you notice that the pipeline takes much longer to complete than before.

What is the MOST effective way to optimize pipeline performance?

Reduce the number of tests executed during the pipeline

Implement parallel execution for test stages and optimize build caching

Disable automated builds and trigger them manually when needed

Increase the server memory and CPU to run Jenkins faster

6. A development team is using Docker for containerized applications. They notice that application builds take longer due to dependencies being downloaded repeatedly.

What is the BEST way to optimize Docker build times?

Use a multi-stage build and cache dependencies properly

Remove all unused dependencies from the application

Always build the image from scratch using --no-cache

Use a single-layer Dockerfile to reduce build complexity

7. What is the primary advantage of using a container over a traditional Virtual Machine (VM)?

Containers provide better security by using separate kernels for each application

Containers require separate operating systems, making them more flexible

Containers share the host OS kernel, making them lightweight and faster to start

Containers include a full hypervisor, allowing them to run multiple operating systems

8. A DevOps engineer wants to run Docker containers without requiring root privileges.

Which of the following container runtimes should they use?

Docker

Podman

VirtualBox

Kubernetes

9. You want to run a web server in a Docker container and make it accessible from your host machine on port 8080.

Which command should you use?

docker run -d -p 8080:80 nginx

docker run -d -p 80:8080 nginx

docker run -d -expose 8080 nginx

docker run -d nginx --network=host

10. Which Dockerfile instruction ensures that an application always runs as a non-root user?

RUN chmod 777 /app

CMD ["sudo", "nginx"]

USER 1000

WORKDIR /root

11. What is the main advantage of using a multi-stage build in a Dockerfile?

It reduces the number of layers in the final image

It removes the need for a base image

It allows the use of multiple containers in a single build process

It ensures that the final image contains only necessary dependencies and binaries

12. Which command is used to create a new Docker network named my_network?

docker run --network my_network

docker network create my_network

docker-compose network create my_network

docker net create my_network

13. You deploy a database in a container and need to ensure that its data persists even after the container is deleted.

What should you use?

A Kubernetes Deployment

A Docker Bind Mount

A Docker Volume

A Dockerfile

14. In Kubernetes, what is the function of a Service?

It creates a container and manages its lifecycle

It exposes a set of Pods to the network and provides a stable endpoint

It deploys multiple containers with automatic scaling

It stores environment variables for a Pod

15. A Kubernetes administrator wants to define a Persistent Volume (PV) in a cluster.

Which of the following configurations is required?

apiVersion: v1, kind: PersistentVolume, and spec.capacity.storage

apiVersion: v1, kind: Service, and spec.ports

apiVersion: apps/v1, kind: Deployment, and spec.template

apiVersion: networking.k8s.io/v1, kind: Ingress, and spec.rules

16. Which Kubernetes command is used to deploy a Pod using a YAML configuration file?

kubectl create -f mypod.yaml

kubectl run -f mypod.yaml

kubectl start pod mypod.yaml

kubectl apply -f mypod.yaml

17. You are responsible for deploying an application using Docker. The application runs in a container, but each time the container stops, all the stored data is lost.

How can you ensure that the application's data persists even after the container is restarted?

Use the --restart=always flag when running the container

Use a Docker Volume to store data persistently

Use the --privileged flag to keep the container running

Store data inside the container's root filesystem

18. A developer is running multiple Docker containers on a single host. The containers need to communicate with each other by their names instead of using IP addresses.

What is the BEST way to achieve this?

Assign each container a static IP address

Use the --link option in docker run

Create a Docker network and connect all containers to it

Use docker-compose without defining a network

19. You are deploying a web application using Kubernetes. Your Pods start successfully, but users cannot access the application.

What is the MOST likely reason for this issue?

The application is using an incorrect image

The Pods do not have enough memory allocated

There is no Kubernetes Service exposing the application

The application is missing environment variables

20. Which of the following AWS CLI commands correctly provisions a new EC2 instance?

aws ec2 create-instance

aws ec2 deploy-instance

aws ec2 run-instances

aws create vm

21. A company wants its cloud-based web application to automatically handle increased traffic by scaling up instances.

Which AWS feature should they use?

EC2 Reserved Instances

Elastic Load Balancer (ELB)

Auto Scaling Group (ASG)

22. A cloud engineer wants to create a pre-configured AWS machine image (AMI) to deploy multiple identical instances.

Which tool should they use?

Terraform

Docker

Packer

Ansible
