Which 802.11 frame type is indicated by a probe response after a (CCNA 200-301)

Correct answer: B. management.
In the 802.11 wireless networking protocol, there are three main frame types:

Data frames: Used to carry user data between the wireless client and the access point.
Management frames: Used for network management and control functions, such as authentication, association, and disassociation.
Control frames: Used to control access to the wireless medium, such as RTS/CTS frames.
When a wireless client sends a probe request frame, it is a management frame used to discover available wireless networks. The access point then responds with a probe response frame, which is also a management frame.

Therefore, the frame type indicated by a probe response after a client sends a probe request is a management frame.
The other options are incorrect:
A. Data frames are used to carry user data, not for management functions.
C. Control frames are used for medium access control, not for management functions.
D. Action frames are a subtype of management frames, not a separate frame type.
