A Custom Guest Portal allows for design flexibility but does not inherently define the account creation or authentication flow, requiring an underlying access type.

The "Sponsored Guest Access" portal type in Cisco ISE is specifically designed for scenarios where guest accounts are created and managed by an internal sponsor or administrator. Users accessing this portal are prompted for a username and password, but they do not have the ability to create their own accounts, perfectly matching the requirements.

"Self Registered Guest Access" portals allow guest users to create their own accounts, which contradicts the requirement that users must not be able to create accounts.

"Hotspot Guest Access" portals typically provide unauthenticated access or simple click-through access, without requiring a username and password, which does not meet the requirements.
