If an organization is changing to include Cisco IP phones in its network, what design feature must be considered to ensure voice quality?

• Voice traffic needs to be tagged with the native VLAN.
• A separate VLAN is needed for voice traffic.
• Voice traffic and data traffic require separate trunk links between switches.
• Additional switch ports that are dedicated to Cisco IP phones are required.

Explanation: A PC commonly connects to an IP phone and the IP phone, in turn, connects to a switch. The phone does not require a separate port. Because voice traffic cannot tolerate much packet delay, it needs to be in a separate VLAN. The voice VLAN can be configured to provide quality of service (QoS), which will ensure that the voice traffic has a higher priority than data traffic.
