DOL DevOps Principles 1 — Questions and Answers
Question 1: What is the primary goal of DevOps?
- To improve collaboration between development and operations for faster, reliable delivery (Correct answer)
- To eliminate the need for testing
- To replace all manual processes
- To reduce the development team size
Correct answer: To improve collaboration between development and operations for faster, reliable delivery
DevOps aims to break down silos between development and operations teams, enabling faster and more reliable software delivery through collaboration and automation.
Question 2: What is Infrastructure as Code (IaC)?
- Managing infrastructure through machine-readable configuration files (Correct answer)
- Writing code on physical servers
- A programming language
- Manual server setup
Correct answer: Managing infrastructure through machine-readable configuration files
IaC treats infrastructure configuration as software code, enabling version control, reproducibility, and automated provisioning.
Question 3: What is a container in software deployment?
- A lightweight, portable unit packaging an application with its dependencies (Correct answer)
- A physical server
- A database
- A network device
Correct answer: A lightweight, portable unit packaging an application with its dependencies
Containers package applications with their dependencies into standardized units that run consistently across different environments.
Question 4: What is continuous delivery?
- Automatically preparing code for release to production after passing tests (Correct answer)
- Deploying code without testing
- Manually releasing code weekly
- Only delivering features once a year
Correct answer: Automatically preparing code for release to production after passing tests
Continuous delivery automatically builds, tests, and prepares code for production release, ensuring software is always in a deployable state.
Question 5: What is a microservices architecture?
- An approach where an application is built as a collection of small, independent services (Correct answer)
- A single large application
- A type of database
- A programming language
Correct answer: An approach where an application is built as a collection of small, independent services
Microservices break applications into small, independently deployable services that communicate via APIs, enabling easier scaling and maintenance.
Question 6: What is monitoring in a DevOps context?
- Continuously observing system performance to detect and resolve issues quickly (Correct answer)
- Watching employees work
- Counting lines of code
- Monthly manual checks
Correct answer: Continuously observing system performance to detect and resolve issues quickly
DevOps monitoring provides real-time visibility into application and infrastructure health, enabling proactive issue detection and resolution.
