Guest users report repeated prompts to authenticate with the portal when connecting to a wireless network. An administrator must configure Cisco ISE to reduce the number of prompts. The solution must meet the requirements:
• Users must be authenticated once.
• When reconnecting to the visitor network, users do not need to be redirected to the login page.
Which action completes the configuration?
To reduce repeated prompts and meet the specified requirements, configure an authorization rule for guest flow to bypass authenticated MAC addresses. This approach ensures users are authenticated once and, when reconnecting, they are not redirected to the login page as their authenticated MAC address will be recognized by the system, preventing further prompts.
For me it's the answer C. https://www.cisco.com/c/en/us/support/docs/security/identity-services-engine/200273-Configure-ISE-Guest-Temporary-and-Perman.html
