RouterA#debug condition username RouterB 
RouterA#debug ppp authentication 
Which of the following PPP authentication debugging messages will be displayed on RouterA?  (Select the best answer.)

  • A: only messages that contain the RouterB user name
  • B: only messages that arrive on the Serial 0/0 interface
  • C: only messages that arrive on the Serial 0/1 interface
  • D: messages that contain the RouterB user name or that arrive on either specified interface



Question 2
Which of the following ping command options should be enabled if you want to determine the MTU size that a given connection supports?  (Select the best answer.)

  • A: the IPv4 donotfragment bit
  • B: a number of pings greater than five
  • C: a datagram size greater than 1,500 bytes
  • D: a timeout value greater than two seconds



Question 3
You issue the debug ppp authentication command on RouterA. RouterA’s Serial 0/0 interface is connected to RouterB. 
RouterA’s Serial 0/1 interface is connected to RouterC. 
You issue the no shutdown command on all interfaces and note that every interface has entered the up state. 
Next, you issue the show debug condition command on RouterA and receive the following output:

   

Which of the following statements is true?  (Select the best answer.)

  • A: A debug condition has been met on the Serial 0/0 interface. 
  • B: A debug condition has been met on the Serial 0/1 interface.
  • C: A debug condition has been met in which the user name is RouterB.
  • D: All debug conditions in this scenario have been met.
  • E: None of the debug conditions in this scenario have been met.



Question 4
You issue the ping 192.168.1.1 size 1501 dfbit command on a Cisco device. You notice a message indicating that the DF bit has been set. However, the ping fails. 
You want to determine the largest datagram that the connection supports without fragmentation. 
Which of the following should you do next?  (Select the best answer.)

  • A: Issue the command without the dfbit parameter.
  • B: Issue the command without the size parameter.
  • C: Issue the command with a lower size parameter value.
  • D: Issue the command without the size parameter and without the dfbit parameter.



Question 5
RouterA’s Serial 0/0 interface is connected to RouterB. RouterA’s Serial 0/1 interface is connected to RouterC. 
You issue the debug ppp authentication on RouterA and then transition all connected interfaces to the up state.  
Next, you issue the show debug condition command on RouterA and receive the following output:

   

Using the least amount of administrative effort, which of the following should you issue to receive PPP authentication debug output from both RouterB and RouterC?  (Select the best answer.)

  • A: no debug alldebug condition interface serial 0/0 -0/1 debug condition username JohnnyB debug ppp authentication
  • B: debug condition interface serial 0/1
  • C: no debug alldebug condition interface serial 0/0 debug condition interface serial 0/1 debug condition username JohnnyB debug ppp authentication
  • D: no debug condition interface all



Question 6
You issue the ping 192.168.1.1 size 1600 command on a Cisco device that is configured with the default system MTU. All pings succeed. 
Which of the following is most likely true?  (Select the best answer.)

  • A: The interface is configured with an MTU of at least 1,600.
  • B: The pings were sent to the destination in a fragmented fashion.
  • C: The DF bit has been enabled, causing the pings to succeed.
  • D: The datagram size specified is below the default MTU value.



Question 7
You administer the network in the following exhibit:

   

All routers are configured to the system MTU defaults. 
You issue the ping 192.168.1.2 size 1500 dfbit command from RouterB, but the ping fails. 
Which of the following is most likely the cause of the failure?  (Select the best answer.)

  • A: The GRE tunnel MTU is 1,476.
  • B: The system default MTU is 1,400.
  • C: The DF bit is not enabled.
  • D: The GRE tunnel does not support fragmented datagrams.



Question 8
Which of the following statements is true regarding OSPF connections over a virtual link?  (Select the best answer.)

  • A: Traffic is encapsulated and decapsulated by tunnel endpoints.
  • B: Packets contain additional overhead because of tunnel headers.
  • C: The transit area can be a stub area.
  • D: Only routing updates are tunneled.



Question 9
Which of the following is not a GRE tunnel state on a Cisco device?  (Select the best answer.)

  • A: Administratively down/down
  • B: Down/up
  • C: Reset/down
  • D: Up/down
  • E: Up/up



Question 10
Which of the following statements is true regarding OSPF connections over a GRE tunnel?  (Select the best answer.)
