✍️ Sample DevOps Questions & Answers
1. What is chaos engineering?
Chaos engineering (e.g., Netflix's Chaos Monkey) proactively breaks things in controlled ways to discover failure modes and verify that systems handle them gracefully.
2. What is the role of a 'build server' in a CI pipeline?
A build server automates the process of compiling code, running tests, and packaging artifacts whenever changes are pushed to the repository.
3. What is a VPC (Virtual Private Cloud)?
A VPC lets you define your own network topology in the cloud, controlling CIDR blocks, subnets, routing tables, and access controls for your resources.
4. What is 'toil' in SRE terminology?
SRE defines toil as work that is manual, repetitive, automatable, tactical, and grows proportionally with service load — teams aim to keep toil below 50% of work time.
5. What is a 'microservices' architecture?
Microservices architecture organizes an application as loosely coupled, independently deployable services each responsible for a specific business capability.
6. What is the principle of least privilege in cloud IAM?

What Practice Test Geeks adds beyond an AI chat for DevOps
An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:
- A timed, full-length DevOps mock exam — 80 questions in 90 minutes with a 70% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
- A fixed DevOps question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable DevOps cheat sheet you can print or save as a PDF.
- DevOps flashcards built from the same question bank.
- Free DevOps practice tests with the correct answer shown after each question.
