CompTIA DataX (CNX-001) — Question 7

A network engineer is establishing a wireless network for handheld inventory scanners in a manufacturing company's warehouse. The engineer needs an authentication mechanism for these scanners that uses the Wi-Fi network and works with the company's Active Directory. The business requires that the solution authenticate the users and authorize the scanners. Which of the following provides the best solution for authentication and authorization?

Answer options

• A. TACACS+
• B. RADIUS
• C. LDAP
• D. PKI

Correct answer: B

Explanation

RADIUS is the best solution because it is specifically designed for remote user authentication and integrates seamlessly with Active Directory for user validation. TACACS+ is less common in environments that utilize Active Directory, while LDAP primarily focuses on directory services and does not provide the same level of authentication functionality as RADIUS. PKI is more suited for encryption and digital signatures rather than direct user authentication.
