問題文

An access point that also serves clients has been given the work of shutting down an unauthorized radio, that radio sits on a channel the access point is not serving, it has been given no class by any rule, and no device of any kind has joined it. The team watches the air and sees that the access point is putting out nothing toward it between one review of its list and the next. What does the guide give as the reason?

1. The frames that go out on each review of the list are put out toward an unauthorized radio only where the radio is on a channel that the access point is already serving, so a radio elsewhere draws none of them.
2. The frames that go out on each review of the list are put out toward an unauthorized radio only where that radio has been given a class by a rule, so an entry that no rule has matched draws none of them.
3. The frames that go out on each review of the list are put out toward an unauthorized radio only where a device has joined it, so a radio with nobody on it draws none of them.
4. The frames that go out on each review of the list are put out toward an unauthorized radio only where the access point has been put into the form that does nothing but watch, so a unit that also serves clients draws none of them.
