問題文

During installation the network settings pass the built-in validation without any warnings. The installer treats this as confirmation that the addressing plan is right. What is the flaw in that reasoning?

選択肢

1. The validation only rules out settings that are internally inconsistent, so a plan can pass and still be the wrong plan for this site.
2. The validation is performed against the addressing plan that was recorded in the site documentation, so a pass means the entered values match that document but not that the document itself is correct.
3. The validation covers only the management network.
4. The validation runs before the addresses are actually assigned, so a pass only describes the intended configuration and any conflict will be reported later when the nodes first request an address.
