A team of five developers is working on a Python web application. They need to track who changed which lines of code, revert to a previous version if a change breaks something, and allow multiple developers to work on different features simultaneously. Which tool should they adopt?

A version control system like Git

A unit testing framework like pytest

A build automation tool like Make

A team is working on a critical application. A developer accidentally committed a change that breaks the build. Other developers have already pulled the broken commit and started working on top of it. The team needs to fix this quickly while preserving the work done by other developers. What is the most appropriate action?

Ask all developers to manually undo the changes in their local copies

Revert the broken commit with a new commit that undoes the changes, then have developers merge the revert

Delete the repository and recreate it from a backup

Force-push to remove the broken commit from the remote repository

What is a key feature of an integrated development environment (IDE)?

Automatic code deployment to production

What is the primary purpose of a version control system?

To automatically fix bugs in the code

To track changes to code and enable collaboration among developers

To deploy code to production servers

To compile code into executable programs

A company is building a cross-platform enterprise application that must run on Windows, Linux, and macOS. The team wants to use a language that is object-oriented and compiles to bytecode that runs on a managed runtime, providing platform independence. Which language should they choose?

PHP — a server-side scripting language

C — a compiled language that produces native machine code for each platform

Java — an object-oriented language that compiles to bytecode for the JVM

JavaScript — an interpreted language that runs in browsers
