Correct answer: lldp run.
Why this is the answer
The correct command to enable LLDP globally on a Cisco IOS ISR is lldp run. This command activates the LLDP process on the device, allowing it to send and receive LLDP advertisements. lldp enable is incorrect because it's not a valid global configuration command for enabling LLDP. lldp transmit is incorrect as it controls the transmission of LLDP packets on an interface, not the global enablement. cdp run and cdp enable are incorrect because they relate to Cisco Discovery Protocol (CDP), Cisco's proprietary discovery protocol, not the industry-standard LLDP.
