200-901 Question 28
Single answerYou are working on a Git-based project that involves collaboration with multiple developers. A colleague has made changes to the main branch in the remote repository, and you want to ensure your local branch is up-to-date before pushing your own changes. Which action should you take to synchronize your local branch with the remote repository?
- A
Use the
git pullcommand to fetch and merge changes from the remote repository into your local branch. - B
Use the
git pushcommand to overwrite the remote branch with your local changes. - C
Use the
git fetchcommand followed bygit mergeto incorporate remote changes into your local branch. - D
Use the
git clonecommand to create a fresh copy of the remote repository.
Show answer and explanation
Correct answer: A
Explanation
The git pull command is the most efficient way to ensure your local branch is synchronized with the remote repository. It combines two steps, fetching the changes from the remote repository and merging them into your local branch, into a single command. While git fetch followed by git merge achieves the same result, it is less efficient than using git pull directly.
- A. Correct.
This is the correct answer. The
git pullcommand fetches changes from the remote repository and automatically merges them into your current branch, ensuring your local branch is up-to-date with the remote branch. - B. Incorrect.
This is incorrect. The
git pushcommand is used to push your local changes to the remote repository; it does not fetch updates from the remote branch. - C. Incorrect.
While this approach would work, it is not the most efficient. The
git pullcommand internally combinesgit fetchandgit mergeinto one step, making it a better option in this scenario. - D. Incorrect.
This is incorrect. The
git clonecommand is used to create a new local copy of the remote repository. It is not relevant for synchronizing an existing local branch with the remote repository.
