200-301 Question #1784: Real Exam Question with Answer & Explanation
The correct answer correctly addresses all three tasks in sequence: first creating both VLANs (77 and 177) with exact topology-specified names on both switches, then assigning those VLANs to access ports using both 'switchport access vlan' for data and 'switchport voice vlan' for
Question
SIMULATION 73 Please use the "Tasks" and "Topology" tabs to complete this lablet. Topology Complete the tasks below: Task 1 Configure Sw1 and Sw2 with both VLANS using the naming on the topology. Task 2 - Assign VLANs to the appropriate interfaces from the topology. - Ensure ports are set to voice and data as assigned on the topology. Task 3 Configure Sw1 and Sw2 for neighbor discovery using LLDP. Answer: - Create VLANs on both SW1 and SW2: conf t vlan 77 name User_VLAN vlan 177 name Voice_VLAN It defines required data and voice VLANs with exact names. - Configure access ports e0/1-3 for data + voice: interface range e0/1-3 switchport mode access switchport access vlan 77 switchport voice vlan 177 spanning-tree portfast It assigns PCs to data VLAN and IP phones to voice VLAN on the same ports. - Enable LLDP neighbor discovery on both switches: lldp run It globally enables LLDP so switches can discover each other.

Explanation
The correct answer correctly addresses all three tasks in sequence: first creating both VLANs (77 and 177) with exact topology-specified names on both switches, then assigning those VLANs to access ports using both 'switchport access vlan' for data and 'switchport voice vlan' for IP phone traffic (a critical distinction for QoS and proper traffic separation), and finally enabling LLDP globally with 'lldp run' so switches can perform Layer 2 neighbor discovery independent of CDP. The combination of data and voice VLAN assignment on the same access port is the industry-standard method for supporting IP phones with attached PCs, where the phone uses the voice VLAN and passes PC traffic through the data VLAN. LLDP is required here rather than (or in addition to) CDP because the question specifically asks for the open-standard neighbor discovery protocol.
