A customer is seeking an upgrade for their campus LAN network. Currently the customer has
access layer switches that support 48 10/100/1000 Mbps ports and one Gigabit uplink. The
customer wants performance in the upgrade but also wants to minimize costs.
The network architect has used the network Traffic Analyzer (NTA) for intelligent Management
Center (IMC) to collect information about the access layer uplinks. These are the results:
For switches on Floor1,the peak utilization in 650 Mbps on a Gigabit uplink.On most days, the
utilization peaksat about 400 Mbps. Peaks usuallyoccur briefly.
Forswitches on Floor 2, thepeak utilizationis 800 Mbpson a Gigabit uplink. During active period,
the utilizationoften remains near 800.
Which is the most appropriate plan for oversubscription in the new access layer? (For this
question, think only about oversubscription and not customer needs for redundancy)

A.
48.1 in all locations

B.
48.1 on floor 1 and 24.1 on floor 2

C.
24.1 on floor 1 and 4.1 on floor 2

D.
24.1 in all locations
