It assigns PPP encapsulation to serial interface 0. Interface serial 0 encapsulation ppp. The same example on the router, assigning PPP encapsulation to port 0 in slot 1, requires the following commands: interface serial 1/0 encapsulation ppp.
I'm a little nervous, taking my CCENT test tomorrow...any last minute advice
my question: I'm confused about this practice question, as i've seen it answered different ways.
the book states answer 3 & 5 are correct, but i think I've seen answer 1 correct somewhere in my studies. Ben 10 protector of earth game online to play.
Question:
You are configuring a Cisco router and connect it with a serial interface to another vendor’s routers serial port. Both routers are configured with HDLC. Which two statements are true regarding this configuration? (Choose two.)
1.The Cisco HDLC frame uses a proprietary “Type” field that may not be compatible with equipment of other vendors
2.HDLC requires a clock rate to be configured on the routers at both ends of the serial link.
3.PPP encapsulation is recommended for serial links between equipment from multiple vendors.
4.Usernames must be configured at both ends of the HDLC serial link.
5.There is a mismatch in the HDLC authentication password configurations.
book explenation:
High-Level Data-Link Control (HDLC) was derived from Synchronous Data Link Control (SDLC), which was created by IBM as a Data Link connection protocol. It is unlikely that two different vendors’ routers will communicate because of a proprietary LLC layer. Answer A is wrong because the Type field is used in an Ethernet frame, not a serial encapsulation.
Thanks!
