Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure an LLDP-MED device policy for voice specifying the VLAN ID and priority.
Why this is correct
Defining the device policy specifies the exact voice VLAN and QoS marking sent to the phone.
- ✗
Enable spanning tree fast-convergence on all voice VLAN ports.
Why it's wrong here
Spanning tree settings are unrelated to LLDP-MED network policy advertisement.
- ✓
Enable LLDP globally under the protocols hierarchy.
Why this is correct
LLDP must be enabled globally before any LLDP-MED features can function.
- ✗
Enable CDP compatibility mode globally.
Why it's wrong here
CDP compatibility is optional and only required if legacy Cisco devices are present.
- ✗
Configure a static ARP entry for every IP phone MAC address.
Why it's wrong here
Static ARP is unnecessary for LLDP-MED operation.
