We are looking into setting up a DAG with our exchange 2013 server and I just have a few questions I'm hoping someone familar with this can answer for me.

1. Can a DAG provide CAS redundancy in addition to the database availability it provides? If EX1 fails will all our users inside of our network on outlook automatically switch to EX2? I've seen some things about needing a load balancer for providing redundancy for the CAS, is that true?

2. When we setup the second exchange server to create our DAG, there is nothing specific we have to do correct. Should be as simple as installing exchange on the server and then following the DAG setup articles out there?

I think really though my main question is the first one. I understand that if I have a failure on one of my exchange servers, I'll have to update my external DNS (or create something such as that points to the second exchange server. But do I need to do anything to facilitate the fail over internally with the outlook clients or will they pick up the new server automatically?
