問題1

The customer's LAN switch SWA is connected to SWB via GigabitEthenet 2/0/1 and to SWC via GigabitEthernet 2/0/2, and the SWA switch has the following configuration:
[SWA] stp region-configuration
[SWA-mst-region] instance 0 vlan 1 to 100[SWA-mst-region] instance 2 vlan 101 to 200[SWA] smart-link group 1
[SWA-smlk-group1] protected-vlan reference-instance 0 [SWA-smlk-group1] port gigabitethernet 2/0/1 master [SWA-smlk-group1] port gigabitethernet 2/0/2 slave [SWA] smart-link group 2
[SWA-smlk-group2] protected-vlan reference-instance 2 [SWA-smlk-group2] port gigabitethernet 2/0/2 master [SWA-smlk-group2] port gigabitethernet 2/0/1 slave If the SWA, SWB, and SWC ports allow all VLANs to pass, what can we learn from the above information? (Multiple choice)

A. The traffic of VLAN 2 on the SWA switch will be upstreamed through Gigabitethernet 2/0/2

B. The traffic of VLAN 2 on the SWA switch will be transmitted upstream through GigabitEthernet 2/0/1.

C. The traffic of VLAN 102 on the SWA switch will be transmitted upstream through GigabitEthe 2/0/2

D. The traffic of VLAN 102 on the SWA switch will be upstreamed through Gigabitethernet 2/0/1

正確答案: B,C

問題2

Regarding multicast maintenance commands, which of the following is correct? (Multiple choice)

A. The multicast routing table is the basis for multicast data forwarding. By viewing the table, you can understand the establishment of (S, G) entries, etc.

B. By viewing the IGMP group information, you can learn about the relevant information of a multicast group maintained by the interface.

C. The multicast forwarding table is directly used to guide the forwarding of multicast data. By viewing this table, you can understand the forwarding status of multicast data.

D. By viewing the PIM routing table, you can learn about the (S, G) or (*, G) table entries.

正確答案: A,B,C,D

問題3

As shown in the figure, there is no connection between SWA and SWB at the beginning. SWA and SWB enable RSTP. When the topology is stable, the ports connecting SWA and SWB assume that SWA will become the new root bridge. Which of the following statements are correct? (Multiple choice)

A. After SWB completes the synchronization process, it will reply with an Agreement message to SWA, and its port E1/0/1 will immediately enter the forwarding state.

B. The designated port of SWB will continue the P/A handshake process with the downstream switch

C. During the P/A process, no timer will be used, so the designated port can quickly enter the forwarding state, thereby achieving rapid network convergence.

D. After receiving the Agreement message sent by SWB, SWA's port E1/0/1 will immediately enter the forwarding state.

正確答案: A,B,C,D

問題4

The multicast IP address is 229.130.130.1, which of the following is its corresponding multicast MAC address?

A. 01-00-5E-82-82-01

B. 00-00-5E-02-82-01

C. 01-00-5E-02-82-01

D. 00-00-5E-82-82-01

正確答案: C

問題5

SSH protocol uses RSA encryption system to ensure transmission security and the legitimacy of the logged-in user. The reason why RSA authentication method is adopted by SSH is that its characteristics are? (Multiple choice)

A. When generating an RSA key pair, it is a pair of related keys including a public key and a secret key.

B. Information encrypted by one public key can only be decrypted by another public key

C. The uniqueness of the private key determines that it can also be used as a digital signature

D. RSA uses public key encryption, which is symmetric encryption and always generates a key pair.

正確答案: A,C

問題6

SNMP protocol adopts a universal C/S structure and has become the current standard protocol for network management. Which of the following descriptions of C/S structure is correct? (Multiple choice)

A. The C/S structure is simple, but performance bottlenecks may occur on the server side in large-scale applications.

B. The Client in the SNMP protocol is the network device, and the Server is the network management workstation.

C. Both the Client and Server in the SNMP protocol listen to the same UDP port number 161

D. The Client in the SNMP protocol is the network management workstation, and the Server is the network device

正確答案: A

問題7

In the switching network shown in the figure, VLAN10 is set as Isolate-user-vlan on switch SWA, VLAN2 and VLAN3 are set as Secondary VLAN of VLAN 10; VLAN4 and VLAN20 are created on switch SWB, and VLAN20 is set as Isolate-user-vlan, and VLAN4 is set as Secondary VLA of VLAN20. After setting the IP addresses of each device as shown in the figure, if the local proxy ARP function is enabled on SWA and SWB, and SWA and SWB are allowed to send ICMP packets, then execute the command tracert 10.1.1.2 on PCA, and PCA will display the jumps required to reach PCB ()

正確答案:

2

問題8
