Very very tough exam. Believe it or not, they ask about the color of the VPN Client's icon. What else can I say? Mind all possible client-2-lan and lan-2-lan scenarios
IPSec over TCP, UDP, NAT-Traversal, LAN-2-LAN w/ NAT, RRI, VRRP, OSPF/RIP...you name it, all the little details trough the global concepts, sorry, but you'll get them on the exam. Keep an eye on main IPSec/IKE concepts, sw version requirements and on the confusing concentrator menu-structure, I've got about 3 'where is that' kindy questions. Cheers and good luck.
Passed w/ 945, 1 less, 2 to go.....
