HPE Aruba Certified Switching Associate (ACSA) — Question 12

Which statement most accurately describes how users with Active Directory credentials authenticate with ClearPass when Active Directory is used as an authentication source for an 802.1x service in ClearPass?

Answer options

• A. A Kerberos request is sent from the Network Access Device to ClearPass which initiates a RADUIS request to the AD server.
• B. A RADIUS request is sent from the Network Access Device to the AD server which communicates with ClearPass.
• C. An LDAP request is sent from the Network Access Device to the AD server which communicates with ClearPass.
• D. An LDAP request is sent from the Network Access Device to ClearPass which initiates a RADIUS request to the AD server.
• E. A RADIUS request is sent from the Network Access Device to the ClearPass which communicates with the AD server.

Correct answer: C

Explanation

The correct answer is C because when Active Directory is used as an authentication source, the Network Access Device sends an LDAP request to the AD server, which is then processed by ClearPass. The other options incorrectly describe the type of request or the sequence of communication between the devices.
