    A new file was added to a main Git repository. An administrator wants to synchronize a local copy with the contents of the main repository. Which of the following commands should the administrator use for this task?

    • Agit reflog
    • Bgit pull
    • Cgit status
    • Dgit push

    Show answer

    Answer: B

    B. git pull The administrator should use the "git pull" command to synchronize the local repository with the main repository. The "git pull" command fetches the latest changes from the remote repository and merges them with the local repository. This will ensure that the local repository has the latest version of the code, including the new file that was added to the main repository. Before running the "git pull" command, the administrator should make sure that they are in the correct branch and that their local repository is in a clean state (i.e., no changes have been made to the local repository since the last time it was synchronized with the main repository).
