Question 2 of 8
What is newly created by a successful fast-forward merge?
A fast-forward moves the branch reference to an existing commit.
Question 3 of 8
What distinguishes the result of a successful true merge?
A non-fast-forward merge records the combined result in a new merge commit with both sides represented in its parent relationship.
Question 4 of 8
What does `--no-ff` do when fast-forward is possible?
`--no-ff` forces a merge commit even when a fast-forward could represent the integration.
Question 5 of 8
What does `--ff-only` do when histories have diverged?
`--ff-only` permits only a fast-forward outcome and refuses when that outcome is impossible.
Question 6 of 8
Why can `--no-commit` not pause an ordinary fast-forward before a merge commit?
The official documentation explicitly notes that fast-forward updates do not create a merge commit.
Question 7 of 8
Which evidence best distinguishes a true merge from a fast-forward?
The commit graph records whether an existing commit was adopted or a new multi-parent merge commit was created.
Question 8 of 8
Which conceptual boundary belongs to a later lesson rather than this one?
This lesson owns history-shape outcomes; conflict state and resolution workflows are separate curriculum ownership.
