M03 SELF-CHECK

Module 3 self-check

Five questions · 4/5 to pass · unlimited retry

1. What does fetch do in this workflow? Integrates all remote edits into the working branch. Retrieves remote objects and updates local remote-reference knowledge. Deletes unique local commits.

2. How does revert differ from working-tree restore? Revert always deletes history. They are interchangeable names. Revert records a new reversal commit; restore changes selected file/index content.

3. A push is rejected because the remote is ahead. What next? Force-push immediately. Preserve local work, fetch, and inspect the histories. Change commit author email until it succeeds.

4. A second checkout builds on the same computer. Which claim fits? Tracked source and instructions reproduced with the recorded installed dependencies. Every operating system is supported. Physical sensor operation is verified.

5. FAULT-hysteresis changes <= to < at the 27.0 °C clear boundary. After revert the same test passes and history includes a new commit. What does this show? The isolated software defect was reversed and its regression case passed. The 28.0 °C entry threshold was physically measured. The original faulty commit no longer exists.

Read the correct answers and explanations

Question 1

Retrieves remote objects and updates local remote-reference knowledge.

Correct: fetch permits inspection before an integration decision.

Integrates all remote edits into the working branch.: Integration is a separate action; pull combines fetch with integration.
Retrieves remote objects and updates local remote-reference knowledge.: Correct: fetch permits inspection before an integration decision.
Deletes unique local commits.: Fetch does not discard local history in the described workflow.

Question 2

Revert records a new reversal commit; restore changes selected file/index content.

Correct: choose based on whether the error is a committed change or working content.

Revert always deletes history.: The original change remains visible in history after a normal revert.
They are interchangeable names.: Their data effects differ and require different starting-state checks.
Revert records a new reversal commit; restore changes selected file/index content.: Correct: choose based on whether the error is a committed change or working content.

Question 3

Preserve local work, fetch, and inspect the histories.

Correct: determine simple advancement versus divergent work before integration.

Force-push immediately.: That can replace remote history without understanding what it contains.
Preserve local work, fetch, and inspect the histories.: Correct: determine simple advancement versus divergent work before integration.
Change commit author email until it succeeds.: Authorship metadata does not resolve history divergence.

Question 4

Tracked source and instructions reproduced with the recorded installed dependencies.

Correct: state the useful result and the reuse of installed tools.

Tracked source and instructions reproduced with the recorded installed dependencies.: Correct: state the useful result and the reuse of installed tools.
Every operating system is supported.: A same-machine clone does not test all platforms or fresh installation.
Physical sensor operation is verified.: Compilation and synthetic replay do not establish physical operation.

Question 5

The isolated software defect was reversed and its regression case passed.

Correct: the result is bounded software recovery evidence.

The isolated software defect was reversed and its regression case passed.: Correct: the result is bounded software recovery evidence.
The 28.0 °C entry threshold was physically measured.: This exercise concerns 27.0 clearing and no physical observation.
The original faulty commit no longer exists.: A revert adds history rather than erasing the original fault.
