LLDP is configured from global configuration mode and only one prompt is in that mode - regardless of the command, any LLDP configuration needs to be done from global config mode.
Only D can be correct as the port-description command for lldp is always configured under ''configure terminal' (global configuration mode).
The correct answer is A. switch(config-if)# lldp port-description. LLDP (Link Layer Discovery Protocol) is configured at the interface level when you want to enable or customize what TLVs (Type-Length-Values) are sent, such as the port description. The lldp port-description command must be applied within interface configuration mode, because LLDP advertisements are sent per interface. The other options are incorrect because they refer to the wrong configuration modes: switch# is exec mode, switch(config-line)# is for terminal lines, and switch(config)# is global config, not appropriate for per-interface LLDP settings.
