The correct answer is associated with the Cisco Discovery Protocol, which is indeed known as CDP. This protocol is specific to Cisco devices and is used for network discovery and device management. CDP allows devices to share information about themselves, such as their hardware and software versions, capabilities, and the system name. This information can be essential for network administrators when managing network topology and troubleshooting connectivity issues. Other protocols listed, such as STP, DTP, and DHCP, serve different purposes. STP (Spanning Tree Protocol) is used to prevent loops in network topologies; DTP (Dynamic Trunking Protocol) is related to switch port trunking, and DHCP (Dynamic Host Configuration Protocol) is utilized for dynamic IP address allocation. None of these protocols are dedicated to discovery in the same manner as CDP, which focuses specifically on providing detailed device information within a Cisco environment.
