In a wireless General Packet Radio Services (GPRS) Virtual Private

Network (VPN) application, which of the following security protocols is
commonly used?

A.
SSL

B.
IPSEC

C.
TLS

D.
WTP

Explanation:
An example is the use of a GPRS-enabled laptop that connects to a
corporate intranet via a VPN. The laptop is given an IP address and a
RADIUS server authenticates the user. IPSEC is used to create the
VPN. As background, GPRS is a second-generation (2G) packet data
technology that is overlaid on existing Global System for Mobile
communications (GSM). GSM is the wireless analog of the ISDN
landline system. The key features of GPRS are that it is always on line
(no dial-up needed), existing GSM networks can be upgraded with
GPRS, and it can serve as the packet data core of third generation
(3G) systems.
Answers SSL and TLS are similar security protocols
that are used on the Internet side of the Wireless Application
Protocol (WAP) Gateway.
For answer WTP is the Wireless Transaction
Protocol that is part of the WAP suite of protocols. WTP is a lightweight,
message-oriented, transaction protocol that provides more
reliable connections than UDP, but does not have the robustness of
TCP.
