The verified answer is C. The correct switchport configuration assigns PCs to the data VLAN and the Cisco phone to the voice VLAN. A typical access port uses switchport access vlan for the attached data device and switchport voice vlan for the phone voice traffic. Cisco CCNA 200-301 v1.1 places this skill in Network Access, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command. Configurations missing either data or voice VLAN assignment will fail the stated placement requirement. In production, this distinction matters because a misapplied command or design choice usually creates an outage, a security gap, or unnecessary troubleshooting noise. The correct choice matches the control-plane, data-plane, wireless, security, or services behaviour described in the scenario and should be preferred over options that merely sound related.
