Wireless Questions

Question 1


Many Cisco access points offer single or double (dual) radio (2.4 and 5.0 GHz).

Note: The wireless controller automates wireless configuration and management functions. It does not connect directly to users.

Question 2


Cisco Wireless is designed to provide 802.11 wireless networking solutions for enterprises and service providers. Cisco Wireless simplifies deploying and managing large-scale wireless LANs and enables a unique best-in-class security infrastructure. The operating system manages all data client, communications, and system administration functions, performs radio resource management (RRM) functions, manages system-wide mobility policies using the operating system security solution, and coordinates all security functions using the operating system security framework.

Question 3


Star is the most popular topology for Ethernet topology but hub and spoke is the most appropriate WAN topology.

In a Hub-and-spoke network topology, one physical site act as Hub (Example, Main Office or Head Quarter), while other physical sites act as spokes. Spoke sites are connected to each other via Hub site. In Hub-and-spoke topology, the network communication between two spokes always travel through the hub (except when using DMVPN Phase II or Phase III where spokes can communicate with each other directly). The networking device at Hub site is often much more powerful than the ones at spoke sites.

Hub and spoke is an ideal topology when most of the resources lie at the Hub site and the branch sites only need to access to the Hub.

Note: Although some books may say Hub-and-spoke and Star topologies are the same but in fact they have difference. When talking about Hub-and-spoke we often think about the communication between Hub site and Spoke sites. When talking about Star we think about the communication between end devices.

Question 4


WiMAX is short for Worldwide Interoperability for Microwave Access. WiMAX is a family of wireless communication standards based on the IEEE 802.16 set of standards.

Satellite Internet provides Internet access via satellite. It is a form of wireless broadband technology. But it is usually slower than DSL and cable modem.

Municipal wireless network is a city-wide wireless network. This is usually done by providing municipal broadband via Wi-Fi to large parts or all of a municipal area by deploying a wireless mesh network. The typical deployment design uses hundreds of wireless access points deployed outdoors, often on poles.

DSLAM (Digital Subscriber Line Access Multiplexer) is a network device, usually at a telephone company central office, that receives signals from multiple customer Digital Subscriber Line (DSL) connections and puts the signals on a high-speed backbone line using multiplexing techniques. It is a cable technology, not a wireless technology.

Cable Modem Termination Systems (CMTS) is a piece of equipment, typically located in a cable company’s headend or hubsite, which is used to provide high speed data services, such as cable Internet or Voice over Internet Protocol, to cable subscribers. It is a cable technology, not a wireless technology.

Question 5


Many rural areas do not have cable Internet access and their only choice to connect to the Internet is via satellite. Satellite internet leverages the hundreds of satellites in orbit around the Earth to send and receive data over the Internet. Of course the speed of this type of connection is much slower than DSL and cable connections. But with new technologies, satellite connections may achieve data speed up to 50 Mbps -> B is correct, D is not correct.

In general, the speeds of popular types of Internet connections are like this: DSL/cable > satellite Internet > dial-up (analog modem).

Satellite Internet uses satellite for Internet connection -> E is not correct

Satellites use radio waves to communicate with the customer’s gateway, also known as a ground station (like a customer’s satellite dish), but not with cellular phone towers -> F is not correct.

For your information, satellite Internet uses high frequency signals, which range from 18.3 gigahertz to 31 gigahertz (Ka band).

Answer A C are two options left and they are acceptable answers. Although in practical they may vary a lot.

Question 6


ACLs on the Cisco Wireless LAN Controller (WLC) are meant to restrict or permit wireless clients to services on its WLAN. With WLC we can verify the ACLs on the ACL web page and verify that your ACL changes were applied to the controller’s interface.

Question 7


802.11g is only compatible with 802.11b, not 802.11a so when 802.11a node broadcast, 802.11g access point cannot receive it.

    I think you have right if we apply the same methodology that if you can edit and remove/add and show ACL event router will can verify ACL’s…

    On documentation I didn’t find any note about special function for that…

    Passed today, no 100% valid dumps at this time. Study well and don’t reply solely on dumps. I used the 411q dumps – 80% of the questions were in the dumps

    Confirming the 411q are the more accurate until now – you can find them here h t t p s : / /g o o .g l/ S B q u u N
