Cwestiwn 1
A project is behind schedule. According to Brooks's law, what happens if you add more developers?
- It finishes much sooner
- It gets even later
- It switches to microservices
- It skips optimization
Cwestiwn 2
Your test suite reaches 100% code coverage. What does that tell you?
- Every line ran during a test
- The code contains no bugs
- All parts work together correctly
- Code review is no longer needed
Cwestiwn 3
A developer restructures messy code without changing what it does. What is this called?
- Paying down bugs
- Feature development
- Refactoring
- Premature optimization
Cwestiwn 4
How are Git and GitHub related?
- They are two names for one tool
- Git only works for teams on GitHub
- GitHub deploys Git code automatically
- Git is a tool; GitHub hosts Git repositories
Cwestiwn 5
What does it mean when an algorithm is O(n²)?
- Its work grows with the square of the input size
- It takes n² seconds to run
- It should be optimized right away
- It takes n² milliseconds per item
Cwestiwn 6
A team ships a quick hack to meet a deadline, planning to clean it up later. What have they created?
- A refactoring
- Technical debt
- A known bug
- An agile sprint
Cwestiwn 7
Which test checks a single function on its own, with its dependencies replaced by fakes?
- An integration test
- An end-to-end test
- A unit test
- A code review
Cwestiwn 8
What does the Agile Manifesto say about documentation?
- Teams should write no documentation
- Planning and documents are banned
- Working software is valued more than documentation
- Every change must deploy straight away
Cwestiwn 9
An app written in Java, which has garbage collection, slowly uses more memory. Could it be a memory leak?
- No, garbage collection prevents all leaks
- No, only C and C++ can leak memory
- No, it just needs early optimization
- Yes, if unused objects are still referenced
Cwestiwn 10
A startup with three developers is building its first product. Which architecture do many experts recommend starting with?
- Dozens of microservices
- A microservice per developer
- A well-structured monolith
