What is the main advantage of using RADIUS in a network?

1. It encrypts all user data

2. It maintains user profiles in a central database

3. It creates a virtual private network

4. It provides real-time data recovery

The correct answer is: It maintains user profiles in a central database

Using RADIUS (Remote Authentication Dial-In User Service) offers the primary advantage of maintaining user profiles in a central database. This centralized approach allows for easier management of user authentication, authorization, and accounting processes across different network devices and services. By having user profiles stored in a single location, network administrators can efficiently keep track of user access rights and permissions, streamline user management, and enhance security through consistent policy enforcement. Additionally, centralizing user data can improve auditing capabilities and simplify the process of adding or removing users from the system. While RADIUS does facilitate some level of encryption for user credentials during transmission to protect against unauthorized access, its primary role lies in user profile management rather than comprehensive data encryption or virtual private network creation. It is not designed for real-time data recovery either, making user management the key strength of RADIUS in networking contexts.
