A network administrator is replacing old switches to support a VoIP deployment. Based on this parameter, which of the following is MOST likely to be implemented on these new switches?

The correct answer is A. PoE. Power over Ethernet (PoE) delivers electrical power through Ethernet cabling, which is essential for VoIP IP phones - it eliminates the need for separate power adapters at each phone. When deploying VoIP, PoE-capable switches are the standard requirement. STP (Spanning Tree…

Explanation

Power over Ethernet (PoE) delivers electrical power through Ethernet cabling, which is essential for VoIP IP phones - it eliminates the need for separate power adapters at each phone. When deploying VoIP, PoE-capable switches are the standard requirement. STP (Spanning Tree Protocol, B) prevents switching loops and is common but not VoIP-specific. NAT (C) translates IP addresses and operates at the router level. VTP (VLAN Trunking Protocol, D) manages VLAN configurations across Cisco switches but is not a VoIP-specific requirement.
