CCNA: Cisco Certified Network Associate — Question 511

Which two protocols are used by an administrator for authentication and configuration on access points? (Choose two.)

Answer options

• A. 802.1Q
• B. RADIUS
• C. Kerberos
• D. TACACS+
• E. 802.1x

Correct answer: B, D

Explanation

RADIUS and TACACS+ are both protocols designed specifically for authentication and configuration management, making them suitable for use on access points. In contrast, 802.1Q is a networking standard for VLAN tagging, Kerberos is a network authentication protocol, and 802.1x is used for port-based network access control, not direct configuration.
