A. One RP can serve multiple multicast groups

B. The announcement message information periodically sent by the C-RP router includes the C-RP address, priority, and the range of multicast groups it serves, etc.

C. After the BSR collects the announcement message information, it summarizes it into an RP-Set and sends it in multicast

D. -A multicast group can select multiple RPs for load sharing

A. The exact matching switch is to complete the forwarding of subsequent packets through hardware after the first packet is searched and processed by software, but it cannot cope with the impact of worms on routing

B. The exact matching switch searches the routing table through software for packet-by-packet forwarding

C. The longest matching switch uses software to search the routing table for

D. The longest matching switch replaces the software routing table with hardware entries, and follows the longest matching principle when searching. In the case of extremely serious network worms, it can still guarantee the wire-speed forwarding of IP packets

A. A VLAN in MSTP can be mapped to multiple spanning tree instances

B. MSTP is defined in 802.1s^ which can not only meet fast convergence, but also achieve load sharing

C. The basic idea of MSTP is to calculate a spanning tree for each VLAN, and each tree corresponds to a spanning tree instance

D. A spanning tree instance in MSTP can contain multiple VLANs

A. SWB can communicate with PCB

B. SWB can communicate with PCA

C. SWB can communicate with SWA

D. SWB can communicate with PCC

E. None of the above answers

A. The destination IP address of the member Report message is the same as the group address in the message

B. The destination IP address of the member Leave message is the same as the group address in the message

C. The destination IP address of the general group query message is 224.0.0.1, and the group address field in the message is 0.0.0.0

D. The destination IP address of the specific group query message is the same as the group address in the message

A. SSH uses TCP port 22 to transmit data and port 23 to establish a connection

B. SSH can also provide a secure transmission channel for FTP

C. SSH uses additional encryption technology to ensure login security

D. SSH and Secure Shell can use DES authentication to ensure data security

A. The definition of the root port and designated port in RSTP is the same as that in STP

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. 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.

D. 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.

A. The designated port will enter the Forwarding state after two ForwardDelay durations

B. The port with the role of Alternate will not go through the Listening state and the Learning state

C. Only the Alternate port will be in the Blocking state

D. Only the designated port will eventually be in the Forwardig state

A. Data reconnaissance with VLAN1 tag will not be stripped when it leaves port Ethemet1/0/1

B. Port Ethemet1/OM is a trunk port, which only allows data from VLAN 1 and VLAN 10 to pass through

C. Port Ethemet1/0/1 is a trunk port, allowing data frames of any VLAN to pass through

D. Data frames without VLAN tags will be tagged with VLAN1 when they enter port Ethernet1/0/1

A. GetRequest

B. SetRequest

C. GetBulkRequest

D. GetNextRequest

A. TACACS+ adopts UDP protocol, high network transmission efficiency

B. TACACS+ protocol uses TCP reliable transmission

C. TACACS+ protocol encrypts all the body of the message with high security

D. The TACACS+ protocol message is simple, which can be combined with authentication and authorization, or separated easily

A. VLAN2

B. VLAN20

C. VLAN 10

D. VLAN4

E. VLAN3

F. VLAN 1

A. If the SWD bridge priority is set to 0, the SWD ports E0/1 and E0/2 will enter the Forwarding state after going through the Listening state and the Learning state

B. If the cost value of the SWD port EO/2 link is changed to 100, the port E0/2 will immediately turn into the new root port and enter the Forwarding state

C. If i sets the bridge priority of SWD to 0, the role of SWA port E0/1 will be changed from a designated port to a root port, and the port will remain in the Forwarding state during the transition.

D. SWD port EO/1 will change from designated port to root port in the Listening state

A. When the RSTP switch and STP switch work together, you need to switch the working mode of the RSTP switch to STP through the command stpmode stp

B. When a port on the RSTP switch is switched to STP mode, the port will no longer have the rapid convergence characteristics of RSTP

C. When the connection between the RSTP switch and the STP switch is disconnected, the port previously connected to the STP switch will automatically switch back to RSTP mode

D. When the RSTP switch and STP switch work together, the port connected to the STP switch will switch to STP mode

A. The reflection port of remote port mirroring is essential

B. The ProbeVLAN of remote port mirroring should prohibit MAC address learning

C. Remote port mirroring must include the mirror source and destination switch
