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. 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

I don’t agree. Voice and data traffics are already separated by VLANs. They cannon have the same VLAN. Physically separate the VoIP phones from the data network means to connect a phone and a computer by two different cables, not by one. This will improve performance and availability. The core switches are full, but there is no word about access switches, those might have additional free ports for such configuration.
My answer is C.
I think question is trying to measure understanding about VLAN and network segmentation by this way. So looking at it from this angle A is the right answer.
Ok we need 99.99% availability. That is very high. That is wy I think it is physically separate.
We can eliminate D. Since it has no bearing and it should be there either way.
That leaves A, B and C.
It is not A since the switches are saturated already. So putting the VoiP on a separate VLAN will not help the switch.
Now it is could be B, but you are at risk of not achieving the High Availablity (HA).
So I think best answer is C. since you have the best chance out of all options to achieve the highest availability and you do not have traffic from other networks affecting your switch.
Anyone agrees ?
I agree. C.
