  DLCI-Data Link Connection Identifier Bits: The DLCI serves to identify the virtual connection so that the receiving end knows which information connection a frame belongs to. Note that this DLCI has only local significance. Frame Relay is strictly a Layer 2 protocol suite.

• Question 1148:

  Scenario:

  You work for a company that provides managed network services, and of your real estate clients running a small office is experiencing network issues, Troubleshoot the network issues.

  Router R1 connects the main office to internet, and routers R2 and R3 are internal routers

  NAT is enabled on Router R1.

  The routing protocol that is enable between routers R1, R2, and R3 is RIPv2.

  R1 sends default route into RIPv2 for internal routers to forward internet traffic to R1.

  Server1 and Server2 are placed in VLAN 100 and 200 respectively, and dare still running router on stick configuration with router R2.

  You have console access on R1, R2, R3, and L2SW1 devices. Use only show commands to troubleshoot the issues.

  

  

  

  

  

  

  

  

  

  

  

  Server1 and Seiver2 are unable to communicate with the rest of the network. Your initial check with system administrators shows that IP address settings are correctly configured on the server side. What could be an issue?

  A. The VLAN encapsulation is misconfigured on the router subinterfaces.
  B. The IP address is misconfigured on the primary router interface.
  C. The Router is missing subinterface configuration.
  D. The Trunk is not configured on the L2SW1 switch.
  A. The VLAN encapsulation is misconfigured on the router subinterfaces.

• Question 1149:

  

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

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

  

  We see the interfaces connecting between them are in "up/down" states which indicates an Layer 2 issue so we should check the configuration of these interfaces carefully with the "show running-config" 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 "ppp authentication chap" command on R1). Branch3 router is sending CHAP hostname "Branch_3" and CHAP password "Branch3_Secret!" to R1 to be authenticated. Therefore we should check if R1 has already been configured with such username and password or not with the "show running-config" command on R1:

  On R1 we see the configured username is "Branch3", not "Branch_3" so the usernames here are mismatched and this is the problem -> Answer A is correct.
