Why has the Branch3 router lost connectivity with R1?

Use only show commands to troubleshoot because usage of the debug command is restricted on the Branch3 and R1 routers.

A. A PPP chap hostname mismatch is noticed between Branch3 and R1.

B. A PPP chap password mismatch is noticed between Branch3 and R1.

C. PPP encapsulation is not configured on Branch3.

D. The PPP chap hostname and PPP chap password commands are missing on the Branch3 router.

Answer: A

Explanation:

First we should check Branch3 (and R1) with the u201cshow ip interface briefu201d command to find any Layer1/Layer 2 issue.

We see the interfaces connecting between them are in u201cup/downu201d states which indicates an Layer 2 issue so we should check the configuration of these interfaces carefully with the u201cshow running-configu201d command and pay attention to these interfaces.

and on Branch3:

We learn from above config is R1 is using CHAP to authenticate Branch3 router (via the u201cppp authentication chapu201d command on R1). Branch3 router is sending CHAP hostname u201cBranch_3u201d and CHAP password u201cBranch3_Secret!u201d to R1 to be authenticated. Therefore we should check if R1 has already been configured with such username and password or not with the u201cshow running-configu201d command on R1:

On R1 we see the configured username is u201cBranch3u201d, not u201cBranch_3u201d so the usernames here are mismatched and this is the problem -> Answer A is correct.
