To use data prefixes when building centralized data policies in the vManage policy wizard, what is the first step?

When building centralized data policies in vManage, the first step to use data prefixes is to create groups of interest. These groups, such as data prefixes, application lists, or VPN lists, act as logical containers that define the specific elements you want to control or match in your policy. By pre-defining these groups, you can then easily reference them in subsequent policy configurations, such as traffic rules. Configuring network topology is a broader setup task, not specific to data prefixes in policy. Applying policies is a final step after the policy is defined. Configuring traffic rules comes after you've defined the groups of interest that those rules will operate on.
