• Question 225:

  Refer to the exhibit.

  

  An engineer is designing an OSPF solution with these requirements:

  1.NMS server will manage R5 and R6.

  2.Upon failure of R1, all NMS traffic should be routed through R4.

  C. Apply static routes on R2 and R3 with IP SLA tracking toward R5 and R6.
  D. Enable the default-information originate command with a higher metric on R2 to R1.
  A. Redistribute OSPF process 1 into process 2 on R1 and R4.

• Question 226:

  What are two purposes of the RPF check in multicast routing? (Choose two.)

  A. to ensure that multicast packets are forwarded if they arrived on the interface used to route traffic back to the source address
  B. to ensure that multicast packets are forwarded if they arrived on the interface used to route traffic to the destination address
  C. to ensure that multicast packets are dropped if they arrived on the interface used to route traffic to the destination address
  D. to ensure that multicast packets are dropped if they arrived on the interface used to route traffic back to the source address
  E. to ensure that multicast packets, no matter the interface they arrived on are forwarded out all interfaces
  A. to ensure that multicast packets are forwarded if they arrived on the interface used to route traffic back to the source address
  C. to ensure that multicast packets are dropped if they arrived on the interface used to route traffic to the destination address
