Which protocol or technology is a Cisco proprietary protocol that is automatically enabled on 2960 switches?

• A. VTP
• B. STP
• C. DTP
• D. RIP

Answer: (C)

The correct choice identifies Dynamic Trunking Protocol (DTP) as a Cisco proprietary protocol that is automatically enabled on Cisco 2960 switches. DTP is utilized for the dynamic negotiation of trunking and the encapsulation type between two switches, making it easier to set up and manage VLANs across the switch network. When two switches are interconnected, DTP allows them to automatically determine whether to form a trunk link, rather than requiring manual configuration. This capability of negotiation significantly simplifies the administration of the network, as it enables the switches to automatically handle trunking characteristics. While other protocols listed may be important in their respective roles—such as Virtual Trunking Protocol (VTP), Spanning Tree Protocol (STP), and Routing Information Protocol (RIP)—DTP specifically focuses on the configuration of trunk links between switches and is unique in being enabled by default on the 2960 series. Understanding DTP's role is essential in ensuring efficient VLAN management and reducing the chance of misconfiguration in switch environments.
