CDM Continuous Integration & Continuous Delivery

Question 1

What is the primary goal of Continuous Integration (CI)?

Accepted Answer

Frequently merge code changes

Answer

The primary goal of Continuous Integration (CI) is to frequently merge code changes from all developers into a shared main branch. This practice helps to detect integration conflicts and bugs early in the development cycle, preventing 'integration hell' and maintaining a stable, working codebase. Automated builds and tests are triggered with each merge.

Question 2

What does Continuous Delivery (CD) enable?

Accepted Answer

Automated release to production

Answer

Continuous Deployment (CD) enables the automated release of every change that passes all automated tests directly into production. This means that once code is committed and passes all checks, it goes live without manual intervention. It allows for the fastest possible delivery of new features and bug fixes to end-users, maximizing agility.

Question 3

Which tool is commonly used for CI/CD pipelines?

Accepted Answer

Jenkins

Answer

Jenkins is a widely used open-source automation server commonly employed for building CI/CD pipelines. It allows developers to automate the entire software development lifecycle, including building, testing, and deploying applications. Its extensive plugin ecosystem supports integration with various other DevOps tools, making it a versatile choice.

Question 4

Why is automated testing important in CI/CD?

Accepted Answer

Detect defects early

Answer

Automated testing is important in CI/CD because it allows for rapid and consistent verification of code changes, enabling the detection of defects early in the development cycle. By running tests automatically at every stage of the pipeline, from unit tests to integration and acceptance tests, bugs can be identified and fixed much sooner. This significantly reduces the cost and effort of defect resolution.

Question 5

What is a build pipeline?

Accepted Answer

Automated code process

Answer

A build pipeline is an automated code process that transforms source code into a deployable artifact. It typically involves a sequence of steps such as compiling code, running tests, packaging the application, and preparing it for deployment. This automation ensures consistency, efficiency, and reliability in the software build process, making it a core component of CI/CD.
