問題文
A firewall is managed centrally, but an engineer once made a change directly on the device during an outage. Why does an analyst have to know which management path a setting came from before deciding whether it is correct?
選択肢
- Because a setting made on the device is discarded the moment the device reconnects to the central system so the analyst has to record it before the connection is restored in order to know what was there.
- Because the device stores settings in a format the central system cannot read so an analyst has to translate the on-box wording before the two views can be lined up.
- Because the same setting can be expressed through more than one path, and what is running on the device may differ from what the central system holds.
- Because settings made on the device are never written to the audit record so the only way to learn what changed is to ask the engineer who was at the console.
