In this task, you will configure the access control policy you want to apply to your managed devices.
If you want to scale your XNC and Device Manager deployment, you can install XNC instances on multiple Windows servers, all pointing to the same XDM instance, and then load balance them using Citrix NetScaler.
The entire XNC configuration is in a single folder (a few XML files). The XNC Connector process detects changes to any file in this folder and automatically reloads the configuration. There is no failover for the master in shared mode. But the system can tolerate the master being down for minutes (for example, to reboot) because the last known good config is cached in the XNC Connector process.
