Question 1

Question 2

Question 3

Explanation

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

Question 4

Explanation

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.

Therefore there are only two available answers left which are 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.

In fact flexibility is not an advantage of leased line connection so if this question only has 4 options as above then maybe we should choose this.

    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
