Answer options

• A. OSPF
• B. VTP trunking
• C. Virtual PBX
• D. RADIUS
• E. 802.1x

Correct answer: D, E

Explanation

RADIUS and 802.1x are both protocols used for authenticating users remotely, making them suitable for remote worker authentication. OSPF is a routing protocol, VTP trunking is related to VLAN management, and Virtual PBX is a telephony solution, none of which are used for user authentication.
