Which of the following devices allows the wired communication devices to connect to a wireless
network using Wi-Fi, Bluetooth or related standards?
A.
Wireless LAN controller
B.
Wireless router
C.
Wireless repeater
D.
WAP
Explanation:
A wireless access point (WAP) is a device that allows wireless communication devices to connect to a
wireless network using Wi-Fi, Bluetooth,
or related standards. The WAP usually connects to a wired network, and it can transmit data
between wireless devices and wired devices on
the network. Each access point can serve multiple users within a defined network area. As people
move beyond the range of one access
point, they are automatically handed over to the next one. A small WLAN requires a single access
point. The number of access points in a
network depends on the number of network users and the physical size of the network.
Answer A is incorrect. A wireless LAN controller is a device that is used in combination with
Lightweight Access Point Protocol (LWAPP)
to manage light weight access points in large quantities by the network administrator or NOC. The
Wireless LAN controller is part of the Data
Plane within the Cisco Wireless Model. The WLAN controller automatically handles the configuration
of anywhere from 6 to 300 wireless
access-points, depending on the model.
Answer C is incorrect. A wireless repeater is a networking device that works as a repeater between
a wireless router and computers.
It is used to connect a client to the network when the client is out of the service area of the access
point. If the wireless repeater is
configured properly, it extends the range of the wireless LAN network.
Answer B is incorrect. A wireless router is a device that performs the functions of a router but also
includes the functions of a wireless
access point. It is commonly used to allow access to the Internet or a computer network without the
need for a cabled connection. It can
function in a wired LAN (local area network), a wireless only LAN, or a mixed wired/wireless
network.
