What kind of performance can DHCP enhance in a VoIP setup?

The correct choice highlights how DHCP (Dynamic Host Configuration Protocol) can significantly improve the efficiency and speed of configuring devices within a VoIP (Voice over Internet Protocol) setup. DHCP automates the process of assigning IP addresses and other network configuration parameters to devices on a network, which reduces the time and effort needed for manual configurations.

In a VoIP environment, where multiple devices like IP phones, softphones, and other endpoints are connected to the network, deploying DHCP allows these endpoints to dynamically acquire their network settings without the need for a network administrator to manually configure each device. This contributes to faster deployment of VoIP services and optimizes the network for voice communication by ensuring that devices can quickly connect to the network and begin functioning with minimal delay.

The other options do not accurately reflect the role of DHCP in a VoIP setup. While DHCP improves network efficiency, it does not enhance the bandwidth speed of individual sessions or eliminate network latency entirely—these factors are influenced by other network elements and configurations. Additionally, DHCP is designed specifically to reduce the need for manual IP configuration rather than require it, making the chosen statement about decreasing setup time the most relevant in this context.
