What does DTP stand for in networking?

• A. Dynamic Transport Protocol
• B. Dynamic Trunking Protocol
• C. Dynamic Transfer Protocol
• D. Data Trunking Protocol

Answer: (B)

DTP stands for Dynamic Trunking Protocol, which is a Cisco proprietary protocol used to negotiate trunking on a link between two Cisco switches or a switch and a router. This protocol simplifies the configuration and management of VLANs (Virtual Local Area Networks) by allowing devices to automatically configure themselves for trunking. When properly configured, DTP can dynamically set the port mode to either access or trunk without requiring manual intervention. By using DTP, network administrators can take advantage of automated trunk link setup, reducing the complexity of VLAN management in larger networks. This protocol supports multiple modes, such as trunk mode, access mode, and desirable mode, which govern the behavior of DTP on the link. The other options refer to terms that either do not exist in standard networking terminology or do not accurately describe the functionality that DTP provides. Dynamic Transport Protocol and Dynamic Transfer Protocol are not recognized protocols in Cisco or general networking contexts, while Data Trunking Protocol lacks the specific linkage to VLAN management and switching that DTP offers.
