Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The switch drops the LLDP packet unless explicit authorization is configured.
Why it's wrong here
LLDP packets are processed by default once LLDP is enabled globally.
- ✓
The switch responds with the configured LLDP-MED network policy containing the voice VLAN ID and Layer 2/3 priority markings.
Why this is correct
The switch replies with the network policy TLV matching the configured parameters.
- ✗
The switch converts the port into a full trunk interface automatically.
Why it's wrong here
The port remains configured as an access port with voice-vlan mapping.
- ✗
The switch reboots the port to force DHCP discovery.
Why it's wrong here
Port rebooting is never a default discovery behavior.
