Which feature reduces data collection and replication to a subset of profile-specific attributes so that anything that is not used for profiling policy will not be replicated?

The feature that reduces data collection and replication to a subset of profile-specific attributes is the Endpoint Attribute Filter. This feature enables the Cisco Identity Services Engine (ISE) to focus solely on the attributes essential for profiling policies, streamlining data by filtering out unnecessary information. By narrowing down the attribute set to only pertinent data, the Endpoint Attribute Filter aids in optimizing performance and reducing network load, as less data is transmitted and stored.

Efficiently managing this data collection is vital for system performance and resource utilization. By ensuring that only relevant attributes are included, this feature plays a significant role in enhancing the efficiency of profiling processes within Cisco ISE, thus allowing for quicker and more accurate endpoint identification and classification based on specified policies.
