A high-speed technology that is always on and can provide data rates up to 52 Mbps is called:

A.
DSL

B.
ISDN

C.
Dial-up

D.
CHAP

Explanation:
Digital subscriber line (DSL) uses copper wires from the central
office to the end user and is always connected, meaning the user does not need to
re-establish a connection. This is true of the technology, but the service provider
providing this service might only allow a connection for a certain time period.
Always-on technologies are targeted by attackers because the system is always
connected and available.
