• Question 103:

  Refer to the exhibit.

  

  What will happen if host 2 issues an IGMP report to join a group?

  A. Both Router A and Router B will get this IGMP report and Router B will propagate a PIM join towards the core network
  B. Both Router A and Router B will get this IGMP report and both of them will propagate a PIM join towards the core network
  C. Only Router A will get this IGMP report and Router A will propagate a PIM join towards the core network
  D. Only Router A will get this IGMP report and as Router A is not PIM DR. so no further action
  A. Both Router A and Router B will get this IGMP report and Router B will propagate a PIM join towards the core network

• Question 104:

  B. No, it is unnecessary to enable PIM on that interface
  C. If it's a physical interface, that interface should be PIM enabled, otherwise it is unnecessary
  D. If the RPF check is using the multicast routing table, that interface should be PIM enabled, otherwise it is unnecessary
