問題文

A file share migration is described as finished. Which evidence establishes that claim?

選択肢

1. A comparison of file counts and sizes between source and destination, a check that permissions resolve to the same effective access for sample accounts, and a confirmation that clients reach the new location by the intended path.
2. A statement from a few users that they can open their files, since they know their own data best.
3. The fact that the source has been decommissioned, which proves the destination is in use.
4. The absence of errors in the copy tool's output, since the tool compares each item after it is written and reports any file whose contents or attributes did not match, so a clean run means the two locations hold the same data and the same permission entries on every object that was copied.
