問題文
Clients in one wing are thrown off the corporate network in bursts through the afternoon. A capture taken in the wing shows a flood of frames that tell clients to leave and the source address of those frames is the wireless address of the corporate access points themselves. No unauthorized unit is found anywhere in the wing. Which explanation should be examined first?
選択肢
- The flood is a normal step of the roaming process because a unit of the corporate network sends a frame of that kind to a client whenever that client walks toward a unit it can hear more strongly.
- Frames of that kind can come only from a unit of the corporate network itself so the units of that wing share a fault of some kind.
- A client with a failing adapter is the sole source of frames of that kind because a failing adapter names the unit that it left.
- A system of a neighbor that watches the air may have judged the corporate network to be the threat and may be sending those frames while it copies the address of the corporate units.
