A network engineer must create a guest portal for wireless guests on Cisco ISE. The guest users must not be able to create accounts; however, the portal should require a username and password to connect. Which portal type must be created in Cisco ISE to meet the requirements?
To meet the requirement where guest users must not be able to create accounts and the portal requires a username and password to connect, the correct portal type in Cisco ISE is a Custom Guest Portal. A Custom Guest Portal enables the administrator to control the user experience and enforce specific requirements, such as preventing users from creating their own accounts while still requiring them to use a username and password for access.
