What type of switch is recommended for a network with numerous IP phones and WLAN APs?

In a network environment that includes numerous IP phones and WLAN access points (APs), the recommended type of switch is one that supports Power over Ethernet (PoE). This is because both IP phones and WLAN APs typically require power for their operation, and PoE allows the switch to deliver both data and electrical power over the same Ethernet cable. This feature simplifies the installation process, reduces the need for separate power supplies, and enhances the overall efficiency of the network infrastructure.

Using PoE switches can lead to improved deployment flexibility, especially in locations where it may be difficult to provide a traditional power source. Additionally, PoE can also help in managing power consumption by enabling network administrators to control power delivery to devices based on their usage needs.

While other options like STP edge ports, QoS, and VLAN tagging are important features for network performance and management, they do not address the specific power delivery requirements of IP phones and WLAN APs. Therefore, supporting PoE is crucial in this context.
