Which ISE Portal Registers BYOD Devices Without Native Supplicants?
An engineer is designing a BYOD environment utilizing Cisco ISE for devices that do not support native supplicants. Which portal must the security engineer configure to accomplish this task?
Community Insight
The question tests which ISE BYOD portal serves devices lacking native supplicant support; the trap is choosing Client Provisioning because the word 'provisioning' sounds like the operation needed for devices that require software.
Cisco ISE's My Devices portal is the portal that lets employees register personal endpoints which cannot run a native supplicant. This page confirms answer C using the ISE admin guide wording, contrasts it with the BYOD and Client Provisioning portals, and summarizes community voting.
Picking B (Client Provisioning). Candidates see 'devices that do not support native supplicants' and assume the engineer must deliver a supplicant, posture agent, or compliance module, but Client Provisioning pushes software to endpoints that can run it — it does not register non-supplicant devices, which is what the question asks for.

Expert Analysis
Why the Answer Is Correct
Cisco's ISE administrator guide describes the My Devices portal as the employee-facing page that "Enables employees to add and register personal devices, including those that do not support native supplicant provisioning, and then manage them." The question asks which portal the security engineer must configure for exactly that population, so the documented match is My Devices (C). The workflow is: an administrative or sponsor-enabled portal is configured on ISE, the user authenticates, and the MAC address or device identity is registered into an endpoint identity group that policy can then authorize. Because the source answer key was recorded as unknown, the verdict here rests on the vendor documentation quoted repeatedly in the discussion, where kornalt, Cnoteone and YmerG all cite the same sentence from the BYOD admin guide. Nothing in the scenario mentions certificate enrollment, SCEP, or posture, which are the features that would point to a different portal.
Why the Other Options Are Wrong
The BYOD portal (A) is the self-service onboarding flow for devices that do carry a native supplicant — it chains guest/BYOD SSIDs, certificate provisioning and supplicant configuration, which is precisely the capability the described endpoints lack. Client Provisioning (B) is the ISE service that delivers supplicant, AnyConnect NAM, posture agent and compliance-module files to endpoints that can install them, so it assumes a supplicant-capable device and is a delivery mechanism rather than the registration portal the question asks about. MDM (D) configures integration with an external mobile device management server to pull compliance and device attributes, not a portal for registering personal devices. denverfly and Han2022 argued for Client Provisioning, but their reasoning describes provisioning settings rather than the registration portal task in the stem.
Community Comment Notes
Seven of the ten comments land on C, several quoting the admin guide line about devices that "do not support native supplicant provisioning"; evdw adds that such devices "cannot be added using the Bring Your Own Device (BYOD) portal." AsaHung notes that Client Provisioning "forces employees to download a posture agent" and that posture is not what the question is asking, which matches the scenario's silence on compliance. XBfoundX prefers B and argues that designing and producing a solution for authenticating non-supplicant devices is the real intent, while 817042b concedes a nuance about "provisioning vs just registering" but still concludes My Devices is "designed for that exact purpose." Han2022 and kornalt both stress that the question asks what the engineer configures, which favors the portal documented for non-supplicant registration.
Official Reference
Exam Strategy
Watch who performs the action in the stem: 'which portal must the security engineer configure' points to a portal whose documented purpose is registering devices without native supplicants, not to the provisioning service that installs software. Eliminate any option whose job is delivering a supplicant, posture agent or MDM integration, since the scenario gives those endpoints no supplicant at all. Do not let the comment vote split push you toward Client Provisioning — the correct choice follows the admin guide sentence, not the poll.
Frequently Asked Questions
Why is the Client Provisioning portal wrong for non-supplicant devices?
Client Provisioning delivers supplicant, posture and compliance software to endpoints that can run it; it does not register devices that have no native supplicant and cannot install one.
When should the BYOD portal be used instead of My Devices in ISE?
The BYOD portal drives self-service onboarding with supplicant and certificate provisioning for capable devices; My Devices covers registering endpoints that lack that supplicant support.
