The question asks for an LLDP delay time of 5 seconds. The Cisco IOS command that controls the LLDP reinitialization delay is: Switch(config)# lldp reinit 5 The lldp reinit command specifies the delay, in seconds, before LLDP initializes on an interface.
I would have picked B if the word "delay" in the question was followed by the phrase "before discarding". The thing is, I don't consider hold time as being a delay in this case. If anything, it is a form of retention (holding on to it no matter how short). You can shorten the hold time to 5 seconds, sure, but it's not delaying anything. You're actually advancing the clock by speeding up the process and telling the protocol to hurry up and discard that 5 second-old record.
Answer is D. reinit Delay (in sec) for LLDP initialization on any interface
