- Question
You need to allow one host to be permitted to attach dynamically to each switch interface. Which two commands must you configure on your catalyst switch to meet this policy?
- Switch(config-if)# ip access-group 10
- Switch(config-if)# switchport port-security maximum 1
- Switch(config)# access-list 10 permit ip host 1
- Switch(config-if)# switchport port-security violation shutdown
- Switch(config)# mac-address-table secure
Options- A. 1 and 3
- B. 2 and 4
- C. 2, 3 and 5
- D. 4 and 5
- Correct Answer
- 2 and 4
ExplanationThe switchport port-security is an important command, and it's super easy with the CNA; however, from the CLI, you can set the maximum number of MAC addresses allowed into the port, and then set the penalty if this maximum has been passed. - 1.

Correct Answer: Switch(config-if)# switchport trunk encapsulation dot1q
Explanation:
If you are on a 2950 switch, then the interface command is just
switchport mode trunk, since the 2950 can only run the IEEE 802.1Q version. However, a 3550 can run both ISL and 802.1Q, so you must use the encapsulation command. The argument to choose 802.1Q for a trunking protocol is
dot1q.
Correct Answer: 127.0.0.1
Explanation:
To test the local stack on your host, ping the loopback interface of 127.0.0.1.
Correct Answer: show ip interface
Explanation:
The
show ip interface command will show you if any outbound or inbound interfaces have an access list set.
Correct Answer: ip access-group 101 in
Explanation:
To apply an access list, the proper command is
ip access-group 101 in.
Correct Answer: 3, 4 and 5
Explanation:
Loopback interfaces are created on a router, and the highest IP address on a loopback (logical) interface becomes the RID of the router but has nothing to do with areas and is optional, so (1) is wrong. The numbers you can create an area with are from 0 to 4,294,967,295 option (2) is wrong. The backbone area is called area 0, so option (3) is correct. All areas must connect to area 0, so option (5) is correct. If you have only one area, it must be called area 0. This leaves option (4), which must be correct; it doesn't make much sense, but it is the best answer.
Correct Answer: debug ip rip
Explanation:
The
debug ip rip command is used to show the Internet Protocol (IP) Routing Information Protocol (RIP) updates being sent and received on the router.
Correct Answer: 200.10.5.64
Explanation:
This is a pretty simple question. A /28 is 255.255.255.240, which means that our block size is 16 in the fourth octet. 0, 16, 32, 48, 64, 80, etc. The host is in the 64 subnet.
Correct Answer: Floods the network with the frame looking for the device
Explanation:
Switches flood all frames that have an unknown destination address. If a device answers the frame, the switch will update the MAC address table to reflect the location of the device.
Correct Answer: 2, 3 and 5
Explanation:
Hubs cannot run full-duplex Ethernet. Full duplex must be used on a point-to-point connection between two devices capable of running full duplex. Switches and hosts can run full duplex between each other, but a hub can never run full duplex.
Correct Answer: About 65-75 feet
Explanation:
The IEEE 802.11a standard provides a maximum data rate of up to 54Mbps, but you need to be close to the access point, somewhere around 65 to 75 feet.
