Question 460
A security policy owner must resolve this specific case: A campus asks students to register personal laptops using the same wireless SSID for onboarding and later EAP-TLS access, but planners assume two SSIDs are mandatory. What is the most suitable solution within these constraints?
Explanation
Correct Answer
Use a supported single-SSID BYOD flow with the correct initial redirect, provisioning steps, and post-enrollment authorization transitions. This is appropriate because iSE BYOD can use one SSID for onboarding and secure access if its policy phases and device configuration are designed accordingly. It should be verified by this evidence: A new laptop completes enrollment and reconnects securely on the intended single SSID.
Incorrect Answers
Both VMs report distinct addresses and ISE assigns the correct independent endpoint records and policies. The repeat risk here is different: a registered tablet receives the BYOD role, while a managed laptop obtains its distinct corporate authorization. A directly relevant preventive control is: Use a supported single-SSID BYOD flow with the correct initial redirect, provisioning steps, and post-enrollment authorization transitions.
The phone completes guided enrollment and uses the required EAP-TLS connection without relying on an employee-wide MAC whitelist. The repeat risk here is different: a registered tablet receives the BYOD role, while a managed laptop obtains its distinct corporate authorization. A directly relevant preventive control is: Use a supported single-SSID BYOD flow with the correct initial redirect, provisioning steps, and post-enrollment authorization transitions.
Test certificate issuance and policy mapping separately from initial portal login. The repeat risk here is different: a registered tablet receives the BYOD role, while a managed laptop obtains its distinct corporate authorization. A directly relevant preventive control is: Use a supported single-SSID BYOD flow with the correct initial redirect, provisioning steps, and post-enrollment authorization transitions.
