Which three of the following are steps that should be taken as part of planning for Profiler usage?

Identifying endpoints that require device identification is a crucial step in planning for Profiler usage within Cisco Identity Services Engine (ISE). This step directly impacts how effectively the Profiler can work to classify and profile devices in your network. By knowing which devices need to be identified, an organization can tailor its strategies to ensure that these devices are appropriately monitored and regulated.

Profiling helps in maintaining security and compliance by giving visibility into the types of devices connecting to the network. Understanding which endpoints are critical for identification allows network administrators to set up necessary policies and configurations that can enhance their overall security posture. This tailored approach aids in efficient device management and consistent application of policies relevant to different device types.

While other choices relate to different aspects of set-up and configuration, they do not focus on the specific need for device identification as an initial step. Therefore, identifying these endpoints is foundational for effectively implementing profiling capabilities in ISE.
