Design an Network Diagram for Hosting 2 Mission Critical Redundant Servers on the internet . This Servers are redundant that means one server is designed to take over only when the another fails .The servers have Gigabit Ethernet Cards . You have 2 Internet Providers over fibre ... Both have assigned you a different IP subnet to be assigned to the servers . we have 2 IP providers so that if one fails another is up . . . You have Layer 2 /3 Switches ..
