（A）RP related configuration

（B）Can PIM-DM when under the interface

（C）Can PIM-SM when under the interface

（D）Hello message priority options

（E）C-BSR related configuration

（A）During C-BSR election, the priority is first compared, and then the IP address of the bootstrap message is compared

（B）C-RP routers periodically send announcement messages in multicast mode

（C）After receiving the C-RP announcement message, the BSR calculates the RP to be selected by each multicast group according to the relationship between the RP and the multicast group, and multicasts the calculation result

（D）BSR is generated through an automatic election process between C-BSR

（A）There are three states for the port in RSTP. After the port enters the Learning state, it starts to send and receive BPDUs and determine the port role.

（B）The Discarding port in RSTP is like the Blocking port in STP. When the port is in the Discarding state, it will not send BPDUs, but will accept BPDUs.

（C）The Alternate port in RSTP is used to back up the root port, and the Backup port is used to back up the designated port.

（D）The definition of the root port and designated port in RSTP is the same as that in STP

（A）[SWC]display interface Ethernet 1/0/1 Ethernet1/0/1 current state: UP ...... PVID: 1 Mdi type: auto Link delay is 0(sec) Port link-type: trunk VLAN passing: 1 (default vlan), 10 VLAN permitted: 1 (default vlan), 2-4094 Trunk port encapsulation: IEEE 802.1q

（C）[SWA]display interface Ethernet 1/0/1 Ethernetl/0/1 current state: UP ...... PVID: 1 Mdi type: auto Link delay is 0(sec) Port link-type: trunk VLAN passing: 1 (default vlan), 10 VLAN permitted: 1 (default vlan), 2-4094 Trunk port encapsulation: IEEE 802.1q

（D）[SWB]display interface Ethernet 1/0/2 Ethernet1/0/2 current state: UP ...... PVID: 1 Mdi type: auto Link delay is 0(sec) Port link-type: trunk VLAN passing: 1 (default vlan), 10 VLAN permitted: 1 (default vlan), 2-4094 Trunk port encapsulation: IEEE 802.1q

（A）After the RP receives the registration message from the DR, it will send a registration stop message and update the local (S, G) and (*, G) entries

（B）To prevent the registration suppression timer from expiring, the DR will send the Register message encapsulating the multicast data to the RP before the timer expires

（C）After receiving the registration stop message, the DR will update the registration suppression timer and continue to send data in multicast mode

（D）The DR router of the multicast source will maintain a registration suppression timer. If the timer expires, the DR will unicast multicast source registration messages to the RP

（A）There can only be one RP in a PIMSM domain

（B）-There can only be one C-BSR in a PIMSM domain

（C）-There can only be one C-RP in a PIMSM domain

（D）-There can only be one BSR in a PIMSM domain

（B）RT2

（C）RT4

（A）Maximize network access security

（B）Minimize the existence of a single point of failure in the network

（C）Minimize network management complexity

（D）Maximize network bandwidth

（A）Host IP addresses in different SubVLANs belong to the same network segment, but due to the isolation effect of Sub VLANs, it is impossible to achieve intercommunication between Sub VLANs.

（B）The hosts in different SubVLANs are isolated at the second layer, and the third layer can communicate with each other through the ordinary proxy ARP technology of the Super VLAN interface

（C）Host IP addresses in different SubVLANs belong to the same network segment, and they can communicate directly with each other through Layer 2 forwarding

（D）Layer 2 isolation between hosts in different SubVLANs, Layer 3 can communicate with each other through the local proxy ARP technology of the Super VLAN interface

（A）If the switch is not configured with the priority of the bridge, the default value is 32768

（B）The smaller the priority value, the lower the priority of the bridge

（C）The step size of bridge priority is 4096

（D）The priority of the bridge is 16 bits in total, and the value range is 0-65535

（A）PCB can communicate with PCC

（B）PCA can communicate with PCC

（C）PCA can communicate with PCB

（D）PCA, PCB and PCC cannot communicate with each other

（A）RT1

（B）RT2

（C）RT3

（A）Since the root bridge ID, root path cost, designated bridge ID, and designated port are the same, the root port of SWD cannot be determined

（B）SWD needs to determine the root port by comparing the ID of the port that receives the configuration BPDU

（C）If the bridge priority of SWD is set to 0, SWD will become the root bridge, and ports E0/1 and E0/2 are designated ports

（D）If the bridge priority of SWD is set to 0, port E0/2 of SWD will only receive configuration BPDUs and not send configuration BPDUs
