Programming 2 - Lesson 11

What is the purpose of merging in Git?

• To create a new branch.

• To combine changes from one branch into another.

• To delete a branch.

• To clone a repository.

Which type of merge occurs when the branch histories have not diverged?

• Rebase

• Detached HEAD

• Fast-Forward Merge

• Three-Way Merge

What is the command to merge a branch named feature into the current branch?

• git merge feature

• git branch feature

• git checkout feature

• git switch feature

What does Git do if you try to switch branches with uncommitted changes?

• Allows the switch and ignores the changes.

• Deletes the changes.

• Prevents the switch if the changes conflict with the new branch.

What is a three-way merge?

• A merge that happens when branch histories have not diverged.

• A merge that involves three branches.

• A merge where the histories of two branches have diverged, and Git creates a merge commit.

• A merge that deletes one of the branches.

What command creates a new branch and switches to it in one step?

• git switch -b branch_name

• git branch branch_name

• git checkout -b branch_name

• git log branch_name

What is a detached HEAD state?

• When the HEAD pointer points directly to a commit instead of a branch.

• When a branch has no commits.

• When a branch is deleted.

• When Git can’t find a commit.

Which command is used to view the commit history in Git?

• git status

• git log

• git merge

• git commit

What happens to a branch after you merge it into another branch?

• It gets automatically deleted.

• It remains in the repository until you manually delete it.

• It is renamed.

• It disappears from the commit history.
