300-430 Question 309
Select 2An enterprise network administrator is tasked with implementing device access controls for a new wireless network deployment. The goal is to ensure secure authentication for network administrators accessing wireless LAN controllers (WLCs) and to maintain a centralized log of all administrative access activities. Which of the following protocols should be implemented to achieve this goal?
- A
RADIUS
- B
TACACS+
- C
SNMPv3
- D
802.1X
- E
LDAP
Show answer and explanation
Correct answers: A, B
Explanation
To implement secure device access controls for WLCs, protocols like RADIUS and TACACS+ are ideal. RADIUS provides centralized authentication and accounting, while TACACS+ offers additional features like granular command authorization and detailed administrative logging. Together, these protocols ensure secure and accountable administrative access to network devices.
- A. Correct.
RADIUS supports secure authentication and accounting and is commonly used for network access control, including administrative access to devices like WLCs.
- B. Correct.
TACACS+ is designed specifically for device administration and provides granular control over command authorization along with centralized logging of administrative activity.
- C. Incorrect.
SNMPv3 is used for network management and monitoring but is not designed for secure authentication or access control.
- D. Incorrect.
802.1X is used for port-based access control to secure user access to the network but is not applicable for administrative access to devices.
- E. Incorrect.
LDAP is used for directory services, such as user authentication, but it does not provide the centralized logging or command authorization capabilities required for secure device administration.
