Question 46

For the description of the PPP link establishment process, which of the following statement is wrong?

A.In the Establish phase, the PPP link performs LCP parameter negotiation. The negotiation content includes the maximum receiving unit MRU, authentication method, magic word and other options.

B.In the Network phase, the PPP link performs NCP negotiation. Select and configure a network layer protocol through NCP negotiation, and negotiate network layer parameters

C.The Dead phase is also called the physical layer unavailable phase. When the two ends of the communication detect that the physical line is activated, they will migrate from the Dead phase to the Establish phase, which is the link establishment phase.

D.PPP link supports half-duplex and full-duplex modes

E.After the NCP negotiation is successful, the PPP link will maintain the communication state and enter the Terminate phase.

Question 47

CAPWAP protocol stipulates the communication standard between AC and Ap. Which of the following statements about CAPWAP protocol is correct?

B.CAPWAP is an application layer protocol based on TCP transmission

C.AP can encapsulate the user's data message in CAPWAP and forward it by AC

D.CAPWAP In order to reduce the burden on the AP, a tunnel is used to transmit control messages and data messages at the same time
