During a network audit, an administrator needs to verify the exact model and software version of devices connected directly to a company's primary Cisco switch. Which protocol would be BEST for collecting this detailed information automatically?
SNMP
LLDP
Using the command line to manually check each device
CDP
Cisco Discovery Protocol (CDP) is specifically designed for collecting detailed data about directly connected Cisco devices, including hardware model and software version. This makes CDP the best choice in networks predominantly utilizing Cisco equipment, as it can gather extensive device-specific information without manual configuration on each connected device. While LLDP also serves to discover device information on a network, it is vendor-neutral and may not provide the same level of detail for specific Cisco device characteristics compared to CDP. The command line provides a manual method to extract information and does not automate the process. SNMP, primarily used for monitoring and managing network devices, focuses more broadly on performance metrics rather than specific device information like model and software version.
