Optimizing Performance and Availability for VoIP and Existing Data Networks
Question
A company is deploying a new VoIP phone system.
They require 99.999% uptime for their phone service and are concerned about their existing data network interfering with the VoIP phone system.
The core switches in the existing data network are almost fully saturated.
Which of the following options will pro-vide the best performance and availability for both the VoIP traffic, as well as the traffic on the existing data network?

A. B. C. D.A.
Option A: Put the VoIP network into a different VLAN than the existing data network. This option involves segregating the VoIP traffic onto a separate VLAN from the existing data network. This approach can provide better performance and availability for both the VoIP traffic and the traffic on the existing data network. By segregating the traffic, the VoIP traffic can be prioritized, which can help to ensure that the call quality remains high, even during periods of high network utilization. Furthermore, this approach can help to prevent the VoIP traffic from interfering with the data traffic and vice versa. This option is a good choice, and it is a standard practice in many networks.
Option B: Upgrade the edge switches from 10/100/1000 to improve network speed. This option involves upgrading the edge switches to a faster speed. While this approach can help to improve network speed, it may not be the best option for improving performance and availability for both the VoIP traffic and the traffic on the existing data network. Additionally, upgrading the edge switches may not solve the core switch saturation issue. While this option can help to provide better network speed, it is not the best choice for meeting the uptime requirements for VoIP.
Option C: Physically separate the VoIP phones from the data network. This option involves physically separating the VoIP phones from the data network. While this approach can help to prevent interference between the VoIP traffic and the data traffic, it may not be the best option for providing the best performance and availability for both the VoIP traffic and the traffic on the existing data network. Physically separating the VoIP phones may require additional cabling and infrastructure, which can be costly and time-consuming.
Option D: Implement flood guards on the data network. This option involves implementing flood guards on the data network. Flood guards are designed to prevent denial-of-service (DoS) attacks by limiting the amount of traffic that can be sent to a specific network device. While implementing flood guards can help to prevent network attacks, it may not be the best option for providing the best performance and availability for both the VoIP traffic and the traffic on the existing data network. Additionally, it may not address the core switch saturation issue.
In conclusion, the best option for providing the best performance and availability for both the VoIP traffic and the traffic on the existing data network is to segregate the VoIP traffic onto a separate VLAN from the existing data network (Option A). This approach can provide better call quality for VoIP traffic, prevent interference between the VoIP traffic and the data traffic, and is a standard practice in many networks.
