문제7

Regarding the comparison of RSTP and STP BPDU processing methods, the correct statement is

A. The aging time of RSTBPDU is reduced from Max age to 3 consecutive Hello Time durations

B. In RSTP, a blocked port can respond immediately when it receives a ground-first BPDU

문제8

The following statements about the registration process of PIM SM are correct (choose one or more)

A. Unlike the PUSH method of PIM DM, in PIM SM, the multicast source only starts to send multicast traffic when there are downstream receivers

B. When a multicast source initially sends traffic, the connected DR will encapsulate several empty Register messages to register with the RP

C. After the RP normally receives the multicast forwarded traffic from the multicast source, it forwards the multicast to its downstream interface until the multicast receiver, forming an RPT from the RP to the multicast receiver along the way.

D. After the RP receives the source registration message for the first time, it will send a (*, G) join message to the multicast source and establish (*, G) entries along the way

정답: C
