HPE Aruba Certified ClearPass Professional (ACCP) — Question 41

Which authentication server option would the network administrator choose to authenticate a wireless user directly against an Active Directory (AD) domain controller without NPS or IAS?

Answer options

• A. LDAP server
• B. RFC 3576 server
• C. TACACS server
• D. RADIUS server

Correct answer: D

Explanation

The correct answer is D, as RADIUS servers can authenticate users against Active Directory directly. Options A, B, and C do not provide direct authentication against AD without additional components like NPS or IAS, making them unsuitable for this scenario.
