B. WAP encryption strength
C. WAP radio power
D. Channel overlay
WAP radio power is the signal strength through which you can specify the range from which you
can stay connected to the network and access internet. Here, when the user is not able to
maintain a stable connection then it is a problem with the signal strength for sure so you can try

Answer(s): D, E
The network layer is responsible for packet forwarding including routing through intermediate

In which of the following layers of the OSI model would MAC addressing be found?
C. Data Link
The ITU-T G.hn standard, which provides high-speed local area networking over existing wires
(power lines, phone lines and coaxial cables), includes a complete data link layer which
provides both error correction and flow control by means of a selective repeat Sliding Window
