Objective 4.4: Design and Deploy High Availability and Disaster Recovery for Hub Transport Role
Hub Transport servers have built-in technologies that mean that each time you add a Hub Transport server to a site, the routing topology configures itself automatically so that the new Hub Transport server is load balanced with existing Hub Transport servers in the site. This means that you don’t need to worry about using technologies like Network Load Balancing, DNS Round Robin, and Failover Clustering to make the Hub Transport role highly available—you just need to ensure that there is more than one Hub Transport server at the site.
