Question 2 of 8
What does `git gc --auto` do?
`--auto` lets Git decide whether automatic housekeeping is warranted.
Question 3 of 8
What does `git gc --no-prune` suppress for that invocation?
`--no-prune` prevents pruning loose objects during that gc run.
Question 4 of 8
Why is `git gc --prune=now` potentially risky?
Immediate pruning removes the normal grace period and can be unsafe during concurrent writes.
Question 5 of 8
What does `git maintenance run --task=gc` select?
The `--task` option explicitly selects a maintenance task.
Question 6 of 8
Why is `--config-file` useful with `git maintenance register` in a lesson?
It avoids modifying the learner’s normal global configuration during the experiment.
Question 7 of 8
Which command is the integrity diagnostic?
`git fsck --full` checks object validity/connectivity; the other commands perform or configure housekeeping.
Question 8 of 8
What is the documented trade-off of `git gc --aggressive`?
Aggressive gc spends considerably more time recomputing deltas and is not automatically worthwhile.
