802.11 technology is typically deployed at which fundamental layer of network
architecture?
- A.Core
- B.Distribution
- C.Access
- D.Network
- Answer & Explanation
- Report
Answer : [C]
Explanation :
Explanation :
| 802.11 wireless networking is typically used to connect client stations to the network via an access point. Autonomous and lightweight access points are deployed at the access layer, not the core or distribution layer. The Physical layer is a layer of the OSI model, not a network architecture layer. |
2.
Which organization is responsible for enforcing maximum transmit power rules in an
unlicensed frequency band?
- A.IEEE
- B.Wi-Fi Alliance
- C.ISO
- D.IETF
- E.None of the above
- Answer & Explanation
- Report
Answer : [E]
Explanation :
Explanation :
| RF communications are regulated differently in many regions and countries. The local regulatory domain authorities of individual countries or regions define the spectrum policies and transmit power rules. |
3.
802.11 wireless bridge links are typically associated with which network architecture layer?
- A.Core
- B.Distribution
- C.Access
- D.Network
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| 802.11 wireless bridge links are typically used to perform distribution layer services. Core layer devices are usually much faster than 802.11 wireless devices, and bridges are not used to provide access layer services. The Network layer is a layer of the OSI model, not a network architecture layer. |
4.
The 802.11-2012 standard was created by which organization?
- A.IEEE
- B.OSI
- C.ISO
- D.Wi-Fi Alliance
- E.FCC
- Answer & Explanation
- Report
Answer : [A]
Explanation :
Explanation :
| The Institute of Electrical and Electronics Engineers (IEEE) is responsible for the creation of all of the 802 standards. |
5.
What organization ensures interoperability of WLAN products?
- A.IEEE
- B.ITU-R
- C.ISO
- D.Wi-Fi Alliance
- E.FCC
- Answer & Explanation
- Report
Answer : [D]
Explanation :
Explanation :
| The Wi-Fi Alliance provides certification testing, and when a product passes the test, it receives a Wi-Fi Interoperability Certificate. |
