Question 1

What is a 'monorepo' and what is a primary DevOps benefit of using one?

Accepted Answer

A single repository containing multiple projects or services; enables atomic cross-service commits and unified CI

Answer

A monorepo hosts multiple projects in one repository, allowing atomic commits that span services and simplifying dependency management and CI/CD pipeline coordination.

Question 2

Which of the following best describes the 'Conventional Commits' specification?

Accepted Answer

A standardized commit message format that enables automated changelog generation and semantic versioning

Answer

Conventional Commits defines a lightweight commit message convention (e.g., feat:, fix:, chore:) that allows tools to automatically determine version bumps and generate changelogs.

Question 3

What problem does a Git pre-commit hook solve in a DevOps workflow?

Accepted Answer

It runs automated checks (linting, formatting, secret scanning) before a commit is recorded locally

Answer

Pre-commit hooks execute scripts before a commit is finalized, enabling early enforcement of code style, quality gates, and security checks without relying solely on CI.

Question 4

In a distributed team using Git, what is the recommended strategy to maintain a clean and understandable project history?

Accepted Answer

Use squash merging or rebase to consolidate noisy feature branch commits before merging

Answer

Squash merging or rebasing condenses many small work-in-progress commits into meaningful, atomic commits, keeping the shared history clean and easier to audit.

Question 5

What is 'GitOps' and which component is central to its implementation?

Accepted Answer

A practice where Git is the single source of truth for infrastructure and application state; central component is a reconciliation agent/operator

Answer

GitOps uses Git repositories as the authoritative source for declarative infrastructure and application config, with an operator (e.g., Flux, Argo CD) continuously reconciling live state to match the repo.
