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 provide the best performance and availability for both the VoIP traffic, as well as the traffic on the existing
data network?
A.
Put the VoIP network into a different VLAN than the existing data network.
B.
Upgrade the edge switches from 10/100/1000 to improve network speed
C.
Physically separate the VoIP phones from the data network
D.
Implement flood guards on the data network
Answer is C. Physically separate the VoIP phones from the data network.
The core switches are almost fully saturated already. Though separating VoIP from data by using VLAN architecture is common practice, the same switches are used. In this case the switches are “almost fully saturated”, assuming they mean processor bandwidth. Added VoIP to a separate VLAN would still be tasking the processor of the switch, thus high availability would not be achieved. The best answer is to physically separate the traffic.
