Which TWO of the following are valid ways to provide access to a guest user?
A Hotspot portal grants network access without authenticating the guest against an identity provider, so no credentials are validated. This satisfies the stem's requirement for a valid guest access method by using a sponsored or self-registered portal that authorises the device, rather than requiring a Microsoft Entra ID account.
Why this answer
Option A is correct because a Hotspot portal is a standard Cisco ISE guest-access method that lets visitors self-register or click through a web page and be granted network access without requiring pre-created credentials, effectively bypassing a traditional login. Option B is correct because the Guest Portal (Sponsored or Self-Registered guest flow) authenticates guest users with a username and password stored in the ISE internal guest identity store, which is the canonical way to provide credentialed guest access. Option C is not a valid guest-access method here because a VPN tunnel is a remote-access technology, not a guest onboarding/authentication mechanism in this context.
Option D is not correct because assigning a static IP only provides addressing, not authentication or authorization for a guest. Option E is not correct because authenticating via the CLI on the NAD is an administrative/device-management action, not a supported way to grant a guest user network access.
Exam trap
SISE often tests the distinction between authentication methods and access provisioning, causing candidates to confuse network configuration (like static IP or VPN) with guest access mechanisms.
