Exam N10-009 topic 1 question 89 discussion

The question is asking how to keep the network itself running under heavy load, not how to improve VoIP performance. In that case, the correct answer is to place limits on the bandwidth which is A

A. A VLAN with 100Mbps speed limits. Explanation: Creating a VLAN specifically for the phones and configuring speed limits (such as 100Mbps) can help manage traffic and ensure that the network remains stable under high load conditions. VLANs segment traffic, which improves performance and reduces congestion by isolating specific types of traffic, such as VoIP and videoconferencing

A is the most correct Answer.

When deploying HD videoconferencing phones, Quality of Service (QoS) and traffic management become essential to ensure the network can handle increased traffic without degradation. Here's why a VLAN with traffic limits is the best solution

C Creating a VLAN with speed limits helps the network engineer manage HD videoconferencing traffic effectively, addressing the concern about excessive network usage while maintaining overall network performance.

The correct answer is: B. An IP helper to direct VoIP traffic Explanation: Configuring an IP helper can assist in directing VoIP traffic to specific devices or servers (such as DHCP, TFTP, or call controllers) and ensure that network resources are properly allocated for VoIP operations. Additionally, implementing Quality of Service (QoS) in conjunction with IP helpers can prioritize VoIP traffic, which is sensitive to delays, jitter, and packet loss, ensuring that videoconferencing traffic does not degrade the overall network performance.

D. Full duplex on all user ports. is the answer, because by configuring full duplex on all user ports, the network can handle more traffic efficiently, just like how super walkie-talkies make conversations smoother!

The speed limit for VOIP traffic makes no sense. B is correct as per chat gpt
