The IEEE 802.11h standard provides an addition 11 channels to the 802.11a standard's 12 non-overlapping channel for a total of 23 non-overlapping channels.
3. Which of the following are valid ways to refer only to host 172.16.30.55 in an IP access list?
The wildcard 0.0.0.0 tells the router to match all four octets. This wildcard format alone can be replaced with the
host command.
4. You want to create a standard access list that denies the subnet of the following host: 172.16.50.172/20. Which of the following would you start your list with?
First, you must know that a /20 is 255.255.240.0, which is a block size of 16 in the third octet. Counting by 16s, this makes our subnet 48 in the third octet, and the wildcard for the third octet would be 15 since the wildcard is always one less than the block size.
5. You are working on a router that has established privilege levels that restrict access to certain functions. You discover that you are not able to execute the command show running-configuration. How can you view and confirm the access lists that have been applied to the Ethernet 0 interface on your router?
The only command that shows which access lists have been applied to an interface is
show ip interface Ethernet 0. The command
show access-lists displays all configured access lists, and
show ip access-lists displays all configured IP access lists, but neither command indicates whether the displayed access lists have been applied to an interface.
6. What is the maximum data rate for the 802.11g standard?
Correct Answer: The split-MAC architecture allows the splitting of 802.11 protocol packets between the AP and the controller to allow processing by both devices.
Explanation:
The split-MAC architecture allows the splitting of 802.11 protocol packets between the Cisco LWAPP-based AP, which handles real-time portions of the protocol, and the WLAN controller, which handles those items that are not time sensitive.
8. You are connecting your access point and it is set to root. What does Extended Service Set ID mean?
Options
A. That you have more than one access point and they are in the same SSID connected by a distribution system.
B. That you have more than one access point and they are in separate SSIDs connected by a distribution system.
C. That you have multiple access points, but they are placed physically in different buildings.
D. That you have multiple access points, but one is a repeater access point.
Correct Answer: That you have more than one access point and they are in the same SSID connected by a distribution system.
Explanation:
Extended Service Set ID means that you have more than one access point and they all are set to the same SSID and all are connected together in the same VLAN or distribution system so users can roam.
9. What is the maximum distance with maximum data rate for 802.11g?
