PPP Questions

November 24th, 2017 Go to comments

Question 1

Question 2

Question 3


Both routers must use the same password for CHAP to authentication.

Question 4


Point-to-point leased line is the most expensive interconnection between two ends as the line is dedicated to a single user, the user should still pay for all available bandwidth, including those unused. -> A is not correct.

With the cost of point-to-point leased line, the full-mesh capability is only achieved when your company has very very strong budget to pay all the bills. To create a full-mesh topology for n sites, we need n*(n-1)/2 leased line connections. For example if we have 6 sites then we need 6*5/2 = 15 leased line connections -> It is nearly impossible for a normal company to achieve full-mesh topology -> B is not correct.

Flexibility is not an advantage of leased line connection -> C is not correct.

Point-to-point leased line simplifies the configuration as the circuit is available on a permanent basis and does not require a connection to be set up before traffic is passed. It does not require to define a permanent virtual circuit (PVC) in the configuration either -> D is correct.

Question 5


Suppose R1 has two Serial interfaces which are directly connected to R2. This is how to configure multilink on R1:

R1(config-if)# interface Serial 0/0
R1(config-if)# encapsulation ppp
R1(config-if)# ppp multilink
R1(config-if)# ppp multilink group 1
R1(config-if)# no shutdown

R1(config-if)# interface Serial 0/1
R1(config-if)# encapsulation ppp
R1(config-if)# ppp multilink
R1(config-if)# ppp multilink group 1
R1(config-if)# no shutdown

R1(config)# interface multilink 1
R1(config-if)# ip address
R1(config-if)# ppp multilink
R1(config-if)# ppp multilink group 1

Therefore we must configure IP address under multilink interface, not physical member interfaces.

Question 6


The Multilink PPP feature provides load balancing functionality over multiple WAN links while providing multivendor interoperability and support for packet fragmentation, proper sequencing, and load calculation on both inbound and outbound traffic.

Multilink PPP combines multiple physical links into a logical bundle called a Multilink PPP bundle. A Multilink PPP bundle is a single, virtual interface that connects to the peer system. Having a single interface (Multilink PPP bundle interface) provides a single point to apply hierarchical queueing, shaping, and policing to traffic flows. Individual links in a bundle do not perform any hierarchical queueing. None of the links have any knowledge about the traffic on parallel links.

Reference: http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/wan_mlp/configuration/xe-3s/wan-mlp-xe-3s-book/wan_cfg_mlppp_conn_xe.html

MLPPP supports two authentication protocols: Password Authentication protocol (PAP) and Challenge-Handshake Authentication Protocol (CHAP)

Question 7

Question 8


The command “ppp authentication chap pap” command indicates the CHAP authentication is used first. If it fails or is rejected by other side then uses PAP instead. If you want to use PAP first (then CHAP) you can use the “ppp authentication pap chap” command.

Question 9


The Multilink PPP (MLPPP) supports CHAP and PAP authentication methods (same as PPP).

    Why there is a question mark against C in the answer of question 4???

    Regarding Q2, why is the ppp-variant of the encapsulation correct? I would say that when you configure nothing but the ip address, IOS will default to a default encapsulation of HDLC for serial links. In any case, there seems to be no reference of the remote router’s used encapsulation method?
    Or,…could it be that whenever IOS default to using the HDLC encapsulation, it also uses the Cisco-proprietary version of it, hence making this an inappropriate encapsulation method to use with non-Cisco routers?

    when no encapsulation is specified then cisco routers run HDLC encapsulation by default, but since the remote site is not cisco router then encapsulation should be specified for the link to work

    Is the question 3 correct ? It doesn’t even send the username and password for authentication, the username on the routers are different. How “The passwords do not match on the two routers” can be the correct answer ?

    Hi @ rafeal

    To configure CHAP, Below are a must:
    1. username of Router is the “hostname” of the peer Router.
    2. password is identical for both Routers

    It’s Only answers , why are the questions ?

  25. Dany1
    June 12th, 2018

    Q1 B is wrong, because chap authentication can be done in:
    one way: ppp authentication chap callin (not part of CCNA) with client and NAS server
    two-way: ppp authentication chap (CCNA exam WAN Technologies 4.1 Configure and verify PPP and MLPPP on WAN interfaces using local authentication)


  26. Dany1
    July 2nd, 2018

    Sorry! My mistake. Q1, answer B is correct. In cisco document is written “Hence, with two-way CHAP, a separate three-way handshake is initiated by each side.”
    So, the question is referring to number of steps, necessary for authentication(three).

    Hi 9Tut: majority of the sections on this page have questions that are not listed, i.e: PPP Questions; questions 1,2,3,7,8 are not shown. other issue is were there are explanations/answers of questions but not the questions itself.

    I don’t know if it’s just me or other users are facing the same issues.

    November 21st, 2018

    Question 1
    Chap uses, 1. Device sends Challenge, 2. Recipe uses RESPOND, 3. Sender uses ACEPT. three-way. Im not sure about the answer C maybe the timer (periodically) for authentication.
