Git Solution: Fundamentals (EN)

This solution guide belongs to the assessment Fundamentals. It does not provide one rigid answer; it defines verifiable answer criteria.

Grading Rubric

Area Expectation
Terms Working tree, index, commit, reference and remote are separated cleanly.
Evidence Answers mention concrete commands and interpretable outputs.
Team impact Shared history, force push, rebase and tags are classified.
Security Credentials, signatures, hooks and secret leaks are assessed.

Additional Review Drills

Use these drills when the primary task is complete and the learner needs another pass over operational reasoning. They are intentionally evidence-oriented and can be answered in a local lab repository.

Drill 01: working tree

  • State which Git state or reference is affected by working tree.
  • Name one command that produces evidence and one field or line in the output that matters.
  • Explain what can be concluded from that evidence and what cannot be concluded from it.
  • Describe the safest recovery path for a shared training repository.

Drill 02: index

  • State which Git state or reference is affected by index.
  • Name one command that produces evidence and one field or line in the output that matters.
  • Explain what can be concluded from that evidence and what cannot be concluded from it.
  • Describe the safest recovery path for a shared training repository.

Drill 03: commit graph

  • State which Git state or reference is affected by commit graph.
  • Name one command that produces evidence and one field or line in the output that matters.
  • Explain what can be concluded from that evidence and what cannot be concluded from it.
  • Describe the safest recovery path for a shared training repository.

Drill 04: branch reference
