Homework Help: Questions and Answers: During a network communication fault, preventing communication with a RADIUS or TACACS+ server, which method of device authentication should still be available?
A. Cloud Access
B. Kerberos
C. Out-of-band Management
D. Local Credentials
Answer:
During a network communication fault, where the device cannot communicate with RADIUS or TACACS+ servers, the appropriate method of device authentication would be one that doesn’t rely on the external network authentication systems.
Given Options: Step by Step Answering
a) Cloud Access
- Cloud Access depends on an active connection to the internet and authentication via cloud services.
- If there’s a network communication fault, access to cloud services would also be unavailable.
b) Kerberos
- Kerberos is a network authentication protocol requiring communication with a central Key Distribution Center (KDC) to function.
- If the network communication is down, the device won’t be able to communicate with the KDC.
c) Out-of-band Management
- Out-of-band Management allows administrators to access the device through a separate management interface, often using a direct or secondary network connection, bypassing the primary network.
- This is a valid method for device management, but it’s not technically a form of device authentication for general users.
- It’s more for administrators to control the device during faults. So, while this method can work, it’s not the primary answer for user authentication.
d) Local Credentials
- Local Credentials are stored directly on the device, allowing users to authenticate without relying on external servers like RADIUS or TACACS+.
- This method would still work during a network communication fault because it does not depend on any external systems.
Final Answer
Based on the above analysis, the correct method of device authentication that should still be available during a network communication fault is:
D. Local Credentials.
