• Question 107:

  

  Refer to the exhibit. The PC is experiencing intermittent connectivity failures to the internet. If ADSL-R1 uses a PPPoE connection, what action can you take to correct the problem?

  A. Configure a system MTU of 1512 on ADSL-R1

• Question 108:

  Refer to the exhibit. You have noticed that when the link between R2 and R3 goes down, traffic to route 192.168.1.0/24 continues to exit R1 through interface F0/0. If all routers on the given network are running EIGRP, what is the most likely reason for the problem?

  C. The R3 metric for 192.168.10.0/24 is too high to be the preferred path
  D. R3 waits until the R2 hold time expires before advertising its path
  B. R2 is still advertising the summary route because one child route exists
