Which Cisco ISE guest service use case is described correctly?

The correct answer is that self-registration supports sending guest credentials via email, SMS, or on-screen. This use case accurately reflects the functionality provided by Cisco Identity Services Engine (ISE) for guest services.

In the self-registration process, guests can enter their details directly into a portal. After submitting their information, Cisco ISE allows system administrators to configure notifications in various forms, such as sending the guest's login credentials through email, text message (SMS), or displaying them directly on the screen. This flexibility is critical in offering a seamless experience to the guests while ensuring security and access management.

This process not only streamlines guest access but also enhances user experience by enabling quick and easy access without necessarily navigating complex approval workflows. The capability to send credentials through multiple channels ensures that guests receive the information in their preferred format, reinforcing an efficient and user-friendly onboarding process.

In contrast, the other options do not accurately describe features or functionality within Cisco ISE’s guest service offerings. Understanding this specific operational detail helps in effectively implementing guest access solutions with Cisco ISE.
