Trouble finding the answer to some study questions?

I have some practice questions I've been looking over and I can't find the answer to them. Was wondering if someone could help. Also, I'm not sure they even pertain to the Network+. Hopefully someone will clearify it for me.
Here are questions:
1. What OSI layer does a dynamic packet filtering firewall operate?
2. What commond on Unix is similar to Telnet on Windows?
3. When installing a new mail server, which entries should be done in the DNS table?

Thanks

1. Network layer or layer 3
2. Telnet comes form UNIX I believe so it is the same command
3. MX records

From my experience, OSI layers and basic Unix commands are fair game, but your third question about the mail server is beyond the scope of the Network+ exam.

The question on a Unix command similar to Windows telnet may be rlogin. Yes, telnet exists in Unix as well as Windows.
