Which statement is true about the repeater access point that is deployed in this wireless network?

A.
The repeater access point should use a different SSID than the SSID configured on the
parent access point.

B.
The repeater access point reduces the throughput in half because it receives and then retransmits each packet on the same channel.

C.
The repeater access point requires a 10 percent channel overlap with channel of the root
access point.

D.
The repeater access point should use a different WEP encryption method than the WEP
encryption that is enabled on the parent access point.

Explanation:
Understanding Repeater Access Points
A repeater access point is not connected to the wired LAN; it is placed within radio range of
an access point connected to the wired LAN to extend the range of your infrastructure or to
overcome an obstacle that blocks radio communication. You can configure either the 2.4-
GHz radio or the 5-GHz radio as a repeater. In access points with two radios, only one radio
can be a repeater; the other radio must be configured as a root radio.
The repeater forwards traffic between wireless users and the wired LAN by sending packets
to either another repeater or to an access point connected to the wired LAN. The data is sent

through the route that provides the best performance for the client. When you configure an
access point as a repeater, the access point’s Ethernet port does not forward traffic.
You can set up a chain of several repeater access points, but throughput for client devices at
the end of the repeater chain will be quite low. Because each repeater must receive and
then re-transmit each packet on the same channel, throughput is cut in half for each repeater
you add to the chain.
