A small company recently added VoIP through its ISP. Users report intermittent call quality issues during peak hours. Which of the following steps should the IT administrator take to solve the issue?

The correct answer is A. Configure the VLAN to split services. Separating VoIP traffic into its own VLAN allows the network to prioritize voice traffic over data traffic, reducing congestion-related latency, jitter, and packet loss that commonly cause call quality issues during peak usage hours.
