Instead of routing network packets through the dual-homed instances, where should each dual-homed instance receive and process requests to fulfil his criteria?

A. On one of the web servers

B. On the front end

C. On the back end

D. Through a security group








 

Suggested Answer: B

Community Answer: B

You can place an elastic network interface on each of your web servers that connects to a mid- tier network where an application server resides. The application server can also be dual-homed to a back-end network (subnet) where the database server resides. If it is set up like this, instead of routing network packets through the dual-homed instances, each dual-homed instance receives and processes requests on the front end and initiates a connection to the back end before finally sending requests to the servers on the back-end network.
