Question 10

what is a fast forward merge?

Answer 10

A fast-forward merge can happen when the current branch has no extra commits compared to the branch that we’re merging. This type of merge doesn’t create a new commit, but rather merges to commits on the branch that we’re merging right into the current
branch.

Question 11

What is no fast forward merge/?

Answer 11

Git will perform a no-fast-forward merge. With a no-fast-forward merge, Git creates a new merging commit on the active branch. The commits parent commit to both the active branch and the branch we want to merge.
