Community Insight
Cisco ISE requires session services to be enabled on the PSN to support guest services, making it the necessary step before configuring a guest portal.
Configuring guest access on Cisco ISE requires specific services to be enabled on the Policy Service Nodes (PSNs). This page establishes that enabling session services is the mandatory prerequisite before a guest portal can be configured.
Choosing to install SSL certificates (Option A) is a common mistake because while certificates are required for secure HTTP, the specific prerequisite service to enable guest functionality on the PSN is session services.

Why the Answer Is Correct
Enabling session services on the Cisco ISE Policy Service Node (PSN) is the fundamental prerequisite for supporting guest access. When session services are enabled, it allows the node to process network access, posture, guest, and client-provisioning services. Without this feature enabled on the PSN, the node cannot host or present guest portals.Why the Other Options Are Wrong
Installing SSL certificates (Option A) is necessary for secure portal access but is not the specific service that must be enabled on the PSN to unlock guest functionality. Creating a node group (Option B) is an optional high-availability configuration and not a strict prerequisite for configuring a guest portal. Enabling profiling services (Option C) allows ISE to identify endpoint devices but is independent of the requirement to enable guest services on the PSN.Community Comment Notes
Commenters highlighted that the "Enable Session Services" checkbox explicitly enables "network access, posture, guest, and client-provisioning services," as noted by ZoneHacker. Techjockeynet also pointed out the configuration path under "Admin > Deployment > Enable Session Services" as the specific hint for guest access.Official Reference
Exam Strategy
When asked about prerequisites for configuring specific ISE services like guest access, remember that the PSN must have the overarching "Session Services" enabled first, as it governs network access, posture, and client provisioning as well.
