Q. What type of DNS record is associated with email servers a. MX /Mail Exchanger and Reverse DNS (99% will miss Reverse DNS unless they have ran their own mail server)
Trick question. And even those who have run their own mail servers could miss it, since most people don't have control over those... the answer should probably note that 'PTR' is the technical term for a reverse DNS lookup.
Q. If I build a Ipsec vpn from Site 1 to Site 2 to Site 3, Can I ping a host on site 3 from site 1. A. No. Ipsec creates rules to join networks. Generally you can't route traffic between tunnels.
ipsec is a solution... wouldn't it be better to base the questions on concepts? Personally, I use PPP & SSH for VPNs...
