Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 1002

A customer wants to provide wireless access to contractors using a guest portal on Cisco ISE. The portal is also used by employees. A solution is implemented, but contractors receive a certificate error when they attempt to access the portal. Employees can access the portal without any errors.
Which change must be implemented to allow the contractors and employees to access the portal?

Answer options

• A. Install a trusted third-party certificate on the Cisco ISE.
• B. Install an internal CA signed certificate on the Cisco ISE.
• C. Install a trusted third-party certificate on the contractor devices.
• D. Install an internal CA signed certificate on the contractor devices.

Correct answer: A

Explanation

Installing a trusted third-party certificate on the Cisco ISE will ensure that all users, including contractors, can establish a secure connection without facing certificate errors. Other options either involve incorrectly placing certificates on the contractor devices or only modifying the Cisco ISE with internal certificates, which may not be recognized by all devices.
