Three companies want to allow their employees to seamlessly connect to each other’s wireless corporate
networks while keeping one consistent wireless client configuration. Each company wants to maintain its own
authentication infrastructure and wants to ensure that an employee who is visiting the other two companies is
authenticated by the home office when connecting to the other companies’ wireless network. All three
companies have agreed to standardize on 802.1x EAP-PEAP-MSCHAPv2 for client configuration. Which of the
following should the three companies implement?
A.
The three companies should agree on a single SSID and configure a hierarchical RADIUS system which
implements trust delegation.
B.
The three companies should implement federated authentication through Shibboleth connected to an LDAP
backend and agree on a single SSID.
C.
The three companies should implement a central portal-based single sign-on and agree to use the same
CA when issuing client certificates.
D.
All three companies should use the same wireless vendor to facilitate the use of a shared cloud based
wireless controller.
