CompTIA Network+ (N10-009) — Question 158

A network engineer is setting up a new VoIP network for a customer. The current network is segmented only for computers and servers. No additional switch ports can be used in the new network. Which of the following does the engineer need to do to configure the network correctly? (Choose two.)

Answer options

• A. Change network translation definitions.
• B. Enable 802.1Q.
• C. Implement a routing protocol.
• D. Set up voice VLANs.
• E. Reconfigure the DNS.
• F. Place devices in the perimeter network.

Correct answer: B, D

Explanation

The correct answers are B and D. Enabling 802.1Q is essential for VLAN tagging, which allows multiple VLANs to share the same physical switch port, crucial for VoIP traffic. Setting up voice VLANs specifically segregates voice traffic from data traffic, ensuring quality of service. The other options do not directly address the segmentation or configuration necessary for VoIP in a constrained environment.
