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)
