Hi all again ,
Thank you very much for your help , but through my study I got these three questions from Skilldrill.com that confuse me, so can you please help me to get the right answers of it ..., I will appreciate your Support

---------------------------------------------
Q1. You are the administrator for a Windows 2000 network. The network contains four Windows 2000 server computers that use IPSec to secure the network communication. While using IPSec Monitor, you determine that hard security associations (SAs) are not being established between computers. After running IPSec Monitor on one of the computers, you find that a soft SA exists between two of the computers. You also find that the security setting for the SA is set to "None". You stop all traffic until the SA times out and verify the SA is gone. Then you start the traffic again. A hard SA is automatically established. What must you do to delete all soft SAs? ( one answer only )

A. Delete the SAs from the IPSec Monitor.
B. Stop all traffic.
C. Restart the policy agent.
D. Refresh the IPSec Monitor.
E. Reboot the server computers.

Q2. Melvin, a consultant hired by a manufacturing company, has been asked to set up a Windows 2000 RAS to allow the company's legacy UNIX computers to dial in and update data. Can Melvin accomplish this and why or why not? ( one answer only )

A. Yes. Melvin can build the RAS and configure the inbound connection to SLIP.
B. No, Windows 2000 RAS supports SLIP on outbound connections only. Windows 2000 does not have a component for inbound SLIP connection over RAS.
C. No, UNIX does not share a common communications protocol with Windows 2000. They would have to purchase a gateway to connect the two networks.
D. Yes, legacy UNIX systems were the first to use Point-to-Point Protocol (PPP) and could connect easily to the Windows 2000 network.
