[SWA]vlan 20
[SWA-vlan20]protocol-vlan ipv4
[SWA-vlan20]quit
[SWA]vlan 30

[SWA-GigabitEthernet1/0/1]mac-vlan enable
[SWA-GigabitEthernet1/0/1]vlan precedence ip-subnet-vlan
After the configuration is complete, it can be judged that PCA will join

A. VLAN30 B. VLAN40 C. VLAN 10 D. VLAN20

Correct Answer: A

Question 4

The customer LAN switches SWA, SWB, and SWC form the RRPP ring main ring 1. If the switches SWB, SWC and SWD form sub-ring 2, the above information can be derived

A. If the switch SWB is the edge node of the sub-ring, it can initiate Maior-Fault packets B. If the switch SWB is the edge node of the sub-ring, it can initiate Edge-Hello packets C. If the switch SWA is the master node of the primary ring, it can initiate Link-Down packets D. If the switch SWA is the master node of the primary ring, it can initiate a Health message

Correct Answer: B,D

Question 5

The configuration command to set the current VLAN type to SuperVLAN on H3C series switches is

Correct Answer:

supervlan

Question 6

The host PCA, PCB and PCC are respectively connected to the Ethernet1/0/1 Ethernet1/0/2 and Ethernet1/0/3 ports of the switch SWA, and their addresses are in the same network segment. Check the VLAN on SWA as follows display:
[SWA]display vlan 10
VLAN ID: 10
VLAN Type: static
Route Interface: not configured
Description: VLAN 0010
Name: VLAN 0010
Tagged Ports: none
Untagged Ports:
Ethernet1/0/1 Ethernet1/0/24
[SWA]display vlan 20
VLAN ID: 20
VLAN Type: static
Route Interface: not configured
Description: VLAN 0020
Name: VLAN 0020
Tagged Ports: none
Untagged Ports:
Ethernet1/0/2Ethernet1/0/24
[SWA]display vlan 30
VLAN ID: 30
VLAN Type: static
Route Interface: not configured
Description: VLAN 0030
Name: VLAN 0030
Tagged Ports: none
Untagged Ports:
Ethernet1/0/1 Ethernet1/0/2 Ethernet1/0/24
It can be judged from the above output information

A. PCA, PCB and PCC cannot communicate with each other B. PCA can communicate with PCC C. PCA can communicate with PCB D. PCB can communicate with PCC

Correct Answer: B,D

Question 7

After executing the display interface Ethernet 1/0/2 command on the switch SWA, the output information is as follows:
[SWA]display interface Ethernet 1/0/2
Ethernet1/0/2 current state: UP
PVID: 10
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
Port priority: 0
It can be judged from the above output

A. Data frames with VLAN1 tags will not be stripped off when they leave port Ethernet1/0/2 B. Port Ethernet1/0/2 only allows data from VLAN 1 and VLAN 10 to pass through C. The only VLANs existing on the switch are VLAN1 and VLAN10 D. Data frames with VLAN20 tags will be discarded when they enter port Ethernet1/0/2

Correct Answer: A,C,D

Question 8

In the networking shown in the figure, the interconnection lines between RT1, RT2, RT3, and RT4 are all 1000M links except the shared Ethernet part which is a 10M link. The OSPF protocol is run to enable routing to communicate with these 4 routers. Both run PIMSM protocol, RP is 1.1.1.1, receivers are connected to the downstream interfaces of RT1 and RT2, and IGMP is enabled on the corresponding interfaces. Then, when the receiver sends a group join request, which of the following routers are connected (*, G) entry exists?

A. RT3 B. RT4 C. RT2 D. RT1

Correct Answer: A,C,D

Question 9
