CAD Continuous Integration and Delivery Questions and Answers

Question 1

What is the primary purpose of implementing Continuous Integration (CI) in an Agile development process?

Accepted Answer

To reduce integration risk and provide rapid feedback by merging and testing code frequently.

Answer

To automatically deploy every new feature to production without human intervention.

Answer

To enforce a strict, phase-gated release process before any code is merged.

Answer

To eliminate the need for a dedicated quality assurance team by automating all tests.

Question 2

A development team frequently experiences "merge hell," where integrating code from multiple long-lived feature branches at the end of a sprint leads to complex conflicts and bugs. Which Agile engineering practice directly addresses this specific problem?

Accepted Answer

Continuous Integration (CI)

Answer

Test-Driven Development (TDD)

Answer

Pair Programming

Answer

Story Point Estimation

Question 3

A team is designing a Continuous Delivery pipeline with the goal of being able to release to production at any time. Which of the following is the most critical prerequisite for ensuring the pipeline can be trusted to produce a reliable release candidate?

Accepted Answer

A comprehensive and reliable automated test suite.

Answer

A dedicated DevOps team to manage all deployments.

Answer

The use of a microservices architecture for the application.

Answer

Manual approval gates for every commit before it enters the pipeline.

Question 4

An Agile team's workflow automatically triggers a build and runs all unit and integration tests upon every commit to the main branch. If all tests pass, the application is packaged and stored in an artifact repository. To move this package to the production environment, a release manager must manually initiate the deployment. What level of automation has this team primarily achieved?

Accepted Answer

Continuous Integration

Answer

Continuous Deployment

Answer

Continuous Delivery

Answer

Ad-hoc Integration

Question 5

A development team is setting up their CI/CD pipeline. They need a central system to monitor the version control repository, orchestrate the execution of build scripts, run automated tests, and report the results. Which component is responsible for this orchestration?

Accepted Answer

A CI/CD Server

Answer

An Integrated Development Environment (IDE)

Answer

An artifact repository

Answer

A feature flag system

Question 6

To accelerate feedback loops and simplify their branching strategy, an Agile team adopts a practice where developers commit their work directly into the shared 'main' branch multiple times per day. To prevent incomplete features from impacting users, they use feature flags. This practice is known as:

Accepted Answer

Trunk-Based Development

Answer

GitFlow

Answer

Feature-Driven Development (FDD)

Answer

Polyrepo Development
