Correct answer: It is configured in global configuration mode..
Why this is the answer
LLDP (Link Layer Discovery Protocol) is configured in global configuration mode using the lldp run command. This enables LLDP globally on the device. It is an industry-standard protocol, not Cisco proprietary, meaning it works across different vendor equipment. While you can adjust LLDP timer values (like update frequency) on an interface or globally, the update frequency is not a fixed value; it's configurable. LLDP operates at Layer 2 (the data link layer) to discover neighboring devices, not the transport layer (Layer 4).
