| Happy Friday everyone!
You've begun reading about the PPTP and L2TP protocols. Your Manager wants to know some information about these 2 protocols.
Which of the following statements are True?
A. PPTP provides encapsulated packets, encrypting and tunneling the data.
B. In L2TP, IPSec provides the encryption, and L2TP provides the tunneling.
C. PPTP and L2TP are only available on Windows 2000 Server.
D. PPTP does not encapsulate the packets, but provides encrypting and tunneling the data.
Good luck and see your Monday for the answer! | |

| It's definately A & B, but pretty sure its C also. Not real sure on that one. | |
| enforcer 2002-10-25, 9:09 am |
| C is false as it's available on w2k Pro (heck this a Pro question)
B looks good IPsec does indeed do the encryption
A or D Hmmmmmmmm
A and B for me | |
| NetChild1985 2002-10-25, 9:26 am |
| I'll go with "A" & "B" as well, but I'm not sure for "A".  | |
| roghan 2002-10-25, 9:38 am |
|  I'm almost sure that only B is correct. Cos IPsec provides encryption for L2TP. | |

| Welcome to the forum roghan! | |

| Glad to see a new "face" here!  | |

| I definitely say answer (B) for sure, but like roghan, I got hung up on answer a's inclusion of "encrypting".
I don't think PPTP actually does any encrypting. Here's the best info I found though...
"..PPTP inherits encryption or compression, or both, of PPP payloads from PPP."

Going to throw an rfc link at you all on PPTP. Now, I actually didn't read through the entire thing, but I skimmed through it and I didn't see anything specific regarding encryption.
http://www.ietf.org/rfc/rfc2637.txt?number=2637 | |

| Now that I look at A & B some more, B is more specific in that respect. If A said something to the effect of "PPTP provides the tunnelling and MPPE provides the encryption" then I can see that being an answer. But right now I'm so confused.  | |

Windows 2000s implementation uses MPPE for encryption in PPTP connections just like L2TP uses IPSec. Inherently PPTP and L2TP are tunneling protocols and by themselves do not encrypt any data. I said A because I was going off the assumption that since this is Windows 2000 we're talking about both PPTP and MPPE since they go hand in hand. And when we're talking about L2TP you can assume that IPSec fits into that equation also.
You are correct in that PPTP does not itself encrypt data, BUT it does allow for data to be encrytped. If you catch my drift.
Yessss...Slinky is wise. He has figured it out. | |
| Surender 2002-10-25, 1:23 pm |
| A,B. | |
| Deja-vue 2002-10-25, 7:49 pm |
| I will go with A and B.
PPTP is also available for Mac OS 9.

| hazz_bin 2002-10-25, 8:27 pm |
| Put me in for A and B. PPTP was/is available under NT4 as well. | |

I know it's a little early but I'll be tied up the rest of the night and for a good part of the morning tomorrow.
And the answers are....A and B
A and B both describe the characteristics of these two protocols.
C is incorrect because these technologies are available in Windows 2000 Professional.
D is incorrect since packets are encapsulated in PPTP. | |
| Linux_Hawk 2002-10-27, 9:07 pm |
| Yup, A & B sound correct. |
