Question

Two routers connect with a serial link, each using its S0/0/0 interface. The link is currently working using PPP. The network engineer wants to migrate to use the Cisco-proprietary HDLC that includes a protocol type field. Which of the following commands can be used to migrate to HDLC successfully? (Choose two answers.)

a. encapsulation hdlc
b. encapsulation cisco-hdlc
c. no encapsulation ppp
d. encapsulation-type auto

Answer 1

a. c.

Step-by-step explanation:

The command of the encapsulation HDLC connects the encapsulation of the interface to the specific HDLC. Furthermore, due to the fact that the default of Cisco routers is applicable to the Cisco-proprietary HDLC on the different interfaces. It also can be used to discard the PPP by using the PPP instructions of the no encapsulation. The correct answers are the answers in options a and c.
