• Question 153:

  Refer to the exhibit.

  

  The switch is not igmp-snooping/proxy capable. 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
