It's Saturday, October 4, and here are the answers to Thursday's Cisco practice exam questions! (Had a little Blogger trouble yesterday, so no questions were posted.)

CCNA Certification And CCENT Certification:

You want a Cisco 2950 switch's port 0/12 to go into err-disabled mode if a host with a MAC address other than 11-22-33-44-55-66 connects to that port. Assuming the port is already in the correct VLAN, what is the full configuration to make this happen?

Answer: You need to enable port security, then define this address as the secure address. If this port is already in its VLAN, we're assuming the port has been configured as an access port, which is one of the port security prerequisites.

You don't need to set the number of secure MAC addresses, since that is one by default.

The port security mode we want is shutdown, and that's also the default, so we don't need to hardcode that, either. The configuration:

SW2(config)#int fast 0/12
SW2(config-if)#switchport port-security
SW2(config-if)#switchport port-security mac-address 1122.3344.5566
