You have several users who dial in to a remote access server using multilink connections,
combining two modems into a single link. Although this provides a higher bandwidth to the users,
you find the server runs out of modem lines frequently, and most users are not using their
connections to their full potential. Which of the following is a solution to this issue?

A.
Disable multilink connections.

B.
Set the maximum number of multilink ports to one.

C.
Use VPN instead of dial-in access.

D.
Enable Bandwidth Allocation Protocol (BAP).
