Which of the following can be used to protect a video conference?

C. WEP
D. PGP
B
Explanation : A non-proprietary approach to securing video conferences as well as VoIP traffic is to extend the H.323 standard to support DES encryption. H.323 is a standard for providing audio-visual communications sessions, such as Web conferences, video conferences, and VoIP. Security for these sessions can be provided by H.235 extensions. H.235 includes the ability to negotiate services and functionality in a generic manner. It allows for the use of both standard and proprietary encryption algorithms.
