Which three statements are true about the show pim join output shown in the exhibit? (Choose three.)
Which three statements are true about the show pim join output shown in the exhibit? (Choose three.)
This output indicates that the multicast stream uses PIM Sparse Mode, as evident from the 'Flag: sparse, spt' and the 'No Prune to RP' statement, which suggests that the rendezvous point (RP) is used. Therefore, the multicast receiver is still using the RP to receive the stream. The presence of the MoFRR Backup upstream interface and neighbor indicates that the multicast stream has been configured with a backup path to allow for fast reroute. The shortest path to the source is through the RP due to the PIM Sparse Mode, which uses RPs for initial multicast source discovery and data forwarding.
Bce as the other two are wrong

not A - SSM address space is 232.0.0.0/8; not D - sparse mode implicate presence of RP
The answer is A, C and E. PIM SSM can technically be used in the entire 224/4 multicast address range
agree with boyseven777
A , C and E
Answer BCE agreed with ocean1908
Exactly, agree with you, correct answers are ACE.
Agree, ACE
A and D are wrong so that leaves BCE
A <= Source: 192.168.100.2; Flags: spt; Upstream state: Join to Source C <= MoFRR Backup upstream interface/neigbor E <= Upstream state: No Prune to RP Also see links in anonymonkey's comment.
100% not ACE, because the multicast section i got zero percent correct after i chose ACE for this question.
PIM SSM introduces new terms for many of the concepts in PIM sparse mode. PIM SSM can technically be used in the entire 224/4 multicast address range, although PIM SSM operation is guaranteed only in the 232/8 range (232.0.0/24 is reserved). The new SSM terms are appropriate for Internet video applications and are summarized in Table 1.
The Internet Assigned Numbers Authority (IANA) has reserved the address range 232.0. 0.0 through 232.255. 255.255 for SSM applications and protocols.
A and B are a single answer and that one is wrong. Therefore the correct are C,D,E.
