The IP phones at a customer site do not pick an IP address from the DHCP. An engineer must temporarily disable LLDP on all ports of the switch to leave only CDP. Which two commands accomplish this task? (Choose two.)
To enable LLDP, use the lldp run command. To disable LLDP, use the no lldp run command.

The answers are correct on how you'd disable LLDP, but what kind of question is this? Why would you even need to disable LLDP when CDP is the first protocol the phones will use.. I have myriads of active deployments where both CDP and LLDP are enabled on the switches. The phones ALWAYS use CDP unless CDP is disabled from the phone's configuration or if the switch doesn't support CDP. Power and VLAN configurations are negotiated by CDP if CDP is available. If it's not, LLDP will STILL work! So why is there a need to disable it? Because it's not proprietary to Cisco? So what?
They need to change the wording on this question to something like, "ABC company policy is that LLDP is not allowed to run on switching infrastructure. Out of the following configurations, select the procedures to disable LLDP." Please correct me if I'm wrong, but the wording on this question is misleading to how the technology even works.
