Question 7

In the switching network shown in the figure, VLAN 10 is set as lsolate-user-vlan on switch SWA, and VLAN 2 and VLAN 3 are set as Secondary VLAN of VLAN 10; VLAN 20 is created on switch SWB, and VLAN 20 is set as lsolate-user-vlan, and VLAN 4 is set as Secondary VLA of VLAN 20. After setting the IP addresses of each device as shown in the figure, the local proxy ARP function is enabled on SWA and SWB. Initially, the switch and PC did not learn their corresponding ARP entries. When PCA pings PCB, PCA will send an ARP request. What is the source MAC address of the ARP request message forwarded by the switch to PCB?

A. 0000.0000.0000

B. 00E0.FC00.0010

C. 00E0.FC00.0020

D. 0011.1111.1111

Correct Answer: C

Question 8

The Ethernets port of switch SWA is configured as follows:
Interface Ethernet 1/0/1 port link-type trunk
Port trunk permit vlan 10 port trunk pvid vlan 20
Now we need to change the Ethernet 1/0/1 port of switch SWA to a Hybrid port, with PVID of VLAN 20, and do not tag the data frames of VLAN 20 when sending them, but tag the data frames of VLAN 10 when sending them. Which of the following configuration processes is correct?

A. None of the above is correct

B. [SWA-Ethernet1/0/1] port link-type hybrid

C. [SWA-Ethernet1/0/1] port link-type access
[SWA-Ethernet1/0/1] port access vlan 20
[SWA-Ethernet1/0/1] port link-type hybrid
[SWA-Ethernet1/0/1] port hybrid vlan 10 tagged

D. [SWA-Ethernet1/0/1] portlink-type access
[SWA-Ethernet1/0/1] port link-type hybrid
[SWA-Ethernet1/0/1] port hybrid pvid vlan 20
[SWA-Ethernet1/0/1] port hybrid vlan 10 tagged

E. [SWA-Ethernet1/0/1] undoportlink-type
[SWA-Ethernet1/0/1] portlink-typeHybrid
[SWA-Ethernet1/0/1] port hybrid pvid vlan 20
[SWA-Ethernet1/0/1] port hybrid vlan 10 tagged
