Answer: AD



6.Switch company1 was configured as shown below:

(config)#vlan access-map pass 10

(config-access-map)#match ip address

(config)# vlan mter pass vlan-list 5-10

Refer to the exhibit. Which statement is true?

A. IP traffic matching access list ABC is forwarded through VLANs 5-10.

B. IP traffic matching VLAN list 5-10 will be forwarded, and all other traffic will be dropped.

C. All VLAN traffic matching VLAN list 5-10 will be forwarded, and all traffic matching access list ABC is dropped.

D. All VLAN traffic in VLANs 5-10 that match access list ABC will be forwarded, and all else will be dropped.

Answer: D



7.The following show command was issued on switch company1:

Company# show port-security interface fastethernet 5/1

Violation mode : shutdown
