T1

Type: folder Points: 20 Prompt: Create folder @solutions/act-01-git-lab/t1-branching-basics/ containing commands.txt (commands+output) and graph.txt (output of git log --oneline --decorate --graph --all) for a repo where you created a branch, made at least one commit on each branch, and switched between branches. Refs:

• mat-07-git#branching
• mat-07-git#creating-and-switching-branches
• mat-07-git#divergent-history-and-viewing-the-graph Rubric:
• commands.txt shows branch creation, switching, and at least one commit on each branch (10)
• graph.txt shows both branches in the graph (6)
• Outputs are readable and clearly separated by command (4)

T2

Type: single_choice Points: 10 Prompt: In the materials, what is HEAD used for? A) It is the server-side copy of your repository B) It is a special pointer that tells Git what branch you are currently on C) It is a list of ignored files D) It is the file that stores your username and email Refs:

• mat-07-git#head-pointer-and-current-branch

T3

Type: file Points: 20 Prompt: Create file @solutions/act-01-git-lab/t3-merge.txt containing commands+output for a merge scenario: create a topic branch, make changes, switch back to the base branch, make another commit, then git merge the topic branch and show the resulting git log --oneline --decorate --graph --all. Refs:

• mat-07-git#fast-forward-merges
• mat-07-git#three-way-merges
• mat-07-git#merge-conflicts-and-resolution
• mat-07-git#divergent-history-and-viewing-the-graph Rubric:
• Shows creation of a topic branch and commits on both branches (8)
• Shows a successful merge and the final graph output (8)
• If a conflict occurred, shows resolution steps (edit, git add, git commit) (3)
• Commands and outputs are clearly labeled (1)

T4

Type: multiple_choice Points: 10 Prompt: Select ALL correct statements about merging from the materials. A) Fast-forward merge happens when there is no divergent history B) Three-way merge creates a merge commit with 2+ parents C) Fast-forward merge always creates a merge commit D) After merging a topic branch, it is common to delete it with git branch -d Refs:

T5

Type: file Points: 20 Prompt: Create file @solutions/act-01-git-lab/t5-remotes.txt containing commands+output for: showing remotes (git remote -v), adding or confirming origin (git remote add ... if needed), and pushing at least one branch to GitHub with git push (use git push -u origin if setting upstream). Refs:

• mat-07-git#showing-and-adding-remotes
• mat-07-git#pushing
• mat-07-git#tracking-branches-upstream Rubric:
• Includes git remote -v output showing at least one remote (6)
• Demonstrates a push to GitHub with command and output (8)
• Shows upstream setup (git push -u) or explains via output that branch is tracking (4)
• Commands and outputs are clearly labeled (2)

T6

Type: essay Points: 20 Prompt: Explain what merge conflict markers mean and list the exact steps to resolve a merge conflict until Git considers it resolved. Refs:

• mat-07-git#merge-conflicts-and-resolution Rubric:
• Correctly explains the meaning of conflict markers (<<<<<<<, =======, >>>>>>>) (8)
• Lists the resolution workflow: edit, stage (git add), commit (git commit) (8)
• Mentions checking state with git status and/or verifying final history (4)
