VPN Netowrk+ Question

thedivine

Alright, the question is as follows

24. What protocol is used to create virtual private networks over several types of networks including TCP/IP?

a. TCP
b. PPP
c. PPTP
d. L2TP

I chose C and got it wrong, But I thought that both C and D were both VPN protocols?

shednik

My first guess would be D, but yes PPTP is another VPN type protocol.
Did it give an answer other than D?

babyxxx

yes C and D are both VPN protocols, but its says over several types of networks including tcp/ip
D is the answer.

thedivine

Nope, D was the only answer it gave. I understand that it is a vpn protocol, but oh well. Thanks

Webmaster

D is the only correct answer and babyxxx explained why: over several types of networks.

PPTP, answer C, works only over TCP/IP networks and not over several types of networks including TCP/IP hence is not a correct answer.

The question is not "which are VPN protocols" but which one works over over several types of networks, including TCP/IP. And that's L2TP, because in addition to IP networks, L2TP supports tunneling through various other types of point-to-point networks including Frame Relay, X.25, and ATM.
