There can be multiple C-BSRs in the
A. PIM-SM domain, but only one BSR can be elected.
B. BSR collects C-RP information by receiving packets of C-RP
C. BSR advertises BSR and C-RP information to all routers in the PIM-SM domain via flood bootstrap messages
D. A C-BSR can also collect C-RP information by receiving C-RP packets

How do 8021w and 8021D handle BPDUs?( Confirmed) The
A. 8021D bridge only forwards BPDU packets received from the root bridge
B. The 8021D bridge does not forward BPDU messages
C. The 8021w bridge forwards only BPDU packets received from the root bridge
D. 8021w Bridge does not forward BPDU packet
In different scenarios, RSTP provides different protection functions, and the wrong statement about this statement is
A. The root protection feature is enabled for the specified port, and its port role can only remain as the specified port
B. When the anti-TC-BPDU packet attack feature is enabled, the number of times the switching device processes IC BPDU packets per unit time is configurable
C. after the BPDU protection function is enabled on the switching device, if the edge port receives RST BPDU, the edge port will be set to a non-remote port and the spanning tree calculation will be re-performed
D. Start the specified port of root protection, when the port receives a better RSTBPDU, the port will enter the Discarding state and is no longer forwarding packets. If the port does not receive a better RSTBPD for a period of time then automatically revert to the normal Forwarding state

A. PPP package
B. IP encapsulation
C. TCP Encapsulation
D. UDP Encapsulation
