C.Queryer election

D.Host joining and leaving the multicast group

Question 47

In the PIM-DM networking, regarding the process of SPT formation (without considering the state refresh mechanism), the correct description is:

A.The diffusion-pruning process is carried out periodically

B.After the process of flooding and pruning, an SPT between the multicast source and the multicast receiver is formed

C.As long as the network topology and unicast routing information remain unchanged, the formed SPT tree will not change

D.The pruned interface no longer sends multicast packets downstream

Question 48

In the network shown in the figure, the corresponding configuration is completed on the switch SWA, and the switch SWA and each PC have learned the corresponding ARP table entry. When PCA accesses the PCB, an ICMP request message is sent, and the destination IP address of the message is

A.20.1.1.2

B.10.1.1.2

C.20.1.1.1

D.10.1.1.1

Question 49

Regarding the configuration of the spanning tree protection mechanism, the following statements are correct

A.BPDU protection needs to be configured in the view of the port designated as an edge port

B.Loop protection commands need to be configured on each port on the physical loop

C.Only when the root bridge protection command is configured on the root bridge in the network will it play a protective role

D.After the TC protection threshold is configured, if the number of TC packets received by the device within the default 10 seconds exceeds the threshold, the device will no longer delete the address table entry within these 10 seconds

Question 50

Two routers are connected together via a LAN to form a VRRP backup group. If the router RTA receives the VRRP protocol message sent by the router RTB, the Priority field Auth Type field value of the message is 2, then
