H3C Constructing H3C High-Performance Campus Networks Sample Questions:

1. In the switching network as shown in the figure, set VLAN10 to Isolate-userW, VLAN2 and VLAN3 to the Secondary VLAN of VLAN 10 on the switch SWA; create VLAN2 VLAN20 on the switch SWB, and set VLAN20 to Isolate-user-vlan, and VLAN4 to After setting the IP address of each device according to the secondary VLA of VLAN20 as shown in the figure, check the MAC address table on SWA, and you can judge that PCA belongs to _ (choose two or more)

A) VLAN2
B) VLAN3
C) VLAN10
D) VLAN20
E) VLAN4
F) VLAN1

2. The customer purchased a router. If the performance index of the router is MTBF>Y14 8 years, and the average maintenance time MTTR<U1, the reliability of the router is

A) 99.999%
B) 99.99%
C) 99.9999%
D) 99.9%

3. After executing the displayinterface Ethernet 1/0/1 command on the switch SWA, the output information is as follows:
[SWA]display interface Ethernet 1/0/1
Ethernet1/0/1 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 reconnaissance with VLAN1 tag will not be stripped when it leaves port Ethemet1/0/1
B) Data frames without VLAN tags will be tagged with VLAN1 when they enter port Ethernet1/0/1
C) Port Ethemet1/0/1 is a trunk port, allowing data frames of any VLAN to pass through
D) Port Ethemet1/OM is a trunk port, which only allows data from VLAN 1 and VLAN 10 to pass through

4. The two switches SWA and SWB are connected together by four Ethernet cables. The corresponding interface on the switch SVVA has the following configuration:
[SWA-Ethernet1/0/1]display this
duplex full
speed 10
[SWA-Ethernet1/0/2]display this
duplex full
speed 10
[SWA-Ethernet1/0/3]display this
duplex half
speed 100
[SWA-Ethernet1/0/4]display this
duplex half
speed 100
It can be known from the above information

A) Four Ethernet ports join the same aggregation group through static aggregation, and the selected ports are Ethernet1/0/1 and Ethernet1/0/3
B) Four Ethernet ports join the same aggregation group through static aggregation, and the selected ports are all four ports
C) Four Ethernet ports join the same aggregation group through static aggregation, and the selected ports are Ethernet1/0/3 and Ethernet1/0/4
D) Four Ethernet ports join the same aggregation group through static aggregation, and the selected ports are Ethernet1/0/1 and Ethernet1/0/2

5. The switch SWA and SWB are connected together by two optical fiber Gigabit Ethernet links. The switch SWA has the following interface configuration:
[SWA]interface GigabitEthernet 1/0/1
[SWA-GigabitEthernet1/0/1]gvrp
[SWA-GigabitEthernet1/0/1]port link-type trunk
[SWA-GigabitEthernet1/0/1]port trunk permit vlan 1 10
[SWA]interface GigabitEthernet 1/0/2
[SWA-GigabitEthernet1/0/2]port link-type trunk
[SWA-GigabitEthernet1/0/2]port trunk permit vlan 1 10
It can be seen from the above

A) If MSTP is enabled on the SWA switch, GigabitEthe1/0/1 and GigabitEthe1/0/2 can participate in forwarding
B) Only by changing the configuration of GigabitEthe1/0/2 to be consistent with GigabitEthe1/0/1, can they join the same aggregation group
C) GigabitEthernet1/0/1 and GigabitEthe1/0/2 cannot join the same aggregation group
D) If SWA4 is switched to enable MSTP, one of GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 will be blocked
