Explanation:
Deploying DNS load balancing on Front End pools and Director pools requires you to perform a couple of extra steps with FQDNs and DNS records.
* A pool that uses DNS load balancing must have two FQDNs: the regular pool FQDN that is used by DNS load balancing (such as pool01.contoso.com), and resolves to the physical IPs of the servers in the pool, and another FQDN for the pools Web services (such as web01.contoso.com), which resolves to virtual IP address of the pool.
In Topology Builder, if you want to deploy DNS load balancing for a pool, to create this extra FQDN for the pools Web services you must select the Override internal Web Services pool FQDN check box and type the FQDN, in the Specify the Web Services URLs for this Pool page.
* To support the FQDN used by DNS load balancing, you must provision DNS to resolve the pool FQDN (such as pool01.contoso.com) to the IP addresses of all the servers in the pool (for example, 192.168.1.1, 192.168.1.2, and so on). You should include only the IP addresses of servers that are currently deployed.
