A hospital CIO tells the network architect that the current network solution is not performing well.
The hospital has access layer that supports 48 10/100/1000 Mbps ports and one Gigabit uplink.
The hospital is seeking an upgrade to provide better performance and redundancy. The CIO
cannot provide the network architect more detailed information about traffic patterns and utilization
but does not want the network architect to install Intelligent Management Center (IMC) and
analyze the network.
The CIO does indicate that these applications are important:
Voice over IP(VoIP)
Scheduling and buildingapplications
Patient data logging
Medical imaging
The network architect needs to plan appropriate oversubscription ration for access layer uplinks.
What is one piece of information that the architect should collect for this task?

A.
Which 802.1p value the VoIP applications use to mark their traffic

B.
How much bandwidth the medical imaging applications require.

C.
Whether the billing applications and patient data require encryption.

D.
Whether the VoIP traffic must be forwarded at Layer 2 or whether it can be routed.
