Software Engineering DevOps and CI/CD Pipelines 1 — Questions and Answers
Question 1: What does CI stand for in the context of DevOps?
- Continuous Improvement
- Continuous Integration (Correct answer)
- Continuous Infrastructure
- Code Inspection
Correct answer: Continuous Integration
CI stands for Continuous Integration, the practice of frequently merging developer code changes into a shared repository with automated builds and tests.
Question 2: Which tool is widely used for container orchestration in DevOps environments?
- Jenkins
- Docker Compose
- Kubernetes (Correct answer)
- Ansible
Correct answer: Kubernetes
Kubernetes is the leading container orchestration platform, automating deployment, scaling, and management of containerized applications.
Question 3: What is 'Infrastructure as Code' (IaC)?
- Writing code that runs on infrastructure
- Managing and provisioning infrastructure through code and configuration files (Correct answer)
- Using code to monitor infrastructure
- Automating infrastructure billing
Correct answer: Managing and provisioning infrastructure through code and configuration files
IaC is the practice of managing and provisioning infrastructure resources through machine-readable configuration files rather than manual processes.
Question 4: In a CI/CD pipeline, what does 'CD' typically stand for?
- Code Deployment
- Continuous Delivery or Continuous Deployment (Correct answer)
- Continuous Documentation
- Configuration Drift
Correct answer: Continuous Delivery or Continuous Deployment
CD stands for Continuous Delivery (automated release preparation) or Continuous Deployment (automated release to production).
Question 5: Which Git branching strategy uses short-lived feature branches merged frequently into the main branch?
- Git Flow
- Trunk-Based Development (Correct answer)
- GitHub Flow
- Release Branching
Correct answer: Trunk-Based Development
Trunk-Based Development involves developers integrating small, frequent commits directly into the main (trunk) branch to support CI practices.
Question 6: What is the primary benefit of containerization using Docker?
- Faster CPU processing
- Consistent runtime environments across development and production (Correct answer)
- Larger storage capacity
- Reduced network latency
Correct answer: Consistent runtime environments across development and production
Docker containers package applications with their dependencies, ensuring consistent behavior across different environments from development to production.
