QUESTION 6:

A developer is working on a new feature in a branch named \’newfeat123456789\’ and the current working primary branch is named \’prim987654321\’. The developer requires a merge commit during a fast-forward merge for record-keeping purposes. Which Git command must be used?

A. git merge –no-ff newfeat123456789

B. git commit –no-ff newfeat123456789

C. git add –commit-ff newfeat123456789

D. git reset –commit-ff newfeat123456789

Correct Answer: A

In the event that you require a merge commit during a fast-forward merge for record-keeping purposes, you can execute git merge with the –no-ff option.

This command merges the specified branch into the current branch but always generates a merge commit (even if it was a fast-forward merge). This is useful for documenting all merges that occur in your repository.
