A customer is seeking an upgrade for their campus LAN network. Currently, the customer has access layer switches that support 18.10/100/1000 Mbps ports and one Gigabit uplink. The customer wants better 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 is 650 Mbps on a Gigabit uplink. On most days, the utilization peaks at about 400 Mbps. Peaks usually occur briefly. For switches on Floo2, the peak utilization is 800 Mbps on a Gigabit Uplink. During active periods, the utilization often remain near 800.
What is most appropriate plan for oversubscription in the new access layer? (For this question, think only about oversubscription and not customer needs for redundancy)

A customer requires high availability for wireless services at branches. The customer also wants to centralize management and traffic distribution as much as possible. What should the architect suggest?
3.
A network architect is designing a redundancy solution for a customer and has learned that there is a single link between two critical network components. During the past 4000 hours of operation, the link has failed twice. The customer estimates that each failure has taken two hours to resolve.
Given this information, what is the availability that this link currently provides?

An architect is planning an HP Wired-WLAN solution for an office with approximately 4000 users who will use the wireless network rather heavily and also need to roam seamlessly. The solution will have 256 MSM 460 access points (APs). What is one reason for using two Hp Wired-WLAN controllers for this solution?
5.
A network architect is choosing fabric module for an HP 10500 Series Switch. Which factors affect the choice?
6.
A network architect is compiling information about the total cost ownership (TCO) for a proposal. Which factors play a role in TCO?
7.
An architect is planning an HP Wired-WLAN solution for a customer with Voice over WLAN (VoWLAN) devices, which support 5 GHz and 2.4 GHz, and the laptops. What is a potential advantage of dual-radio 802.1n APs for this environment?
8.
A network architect has created a quality of service (QoS) for an HP 5900 Series switch that uses four traffic classes. Class of Service (CoS) 5 for voice traffic. CoS 4 for Video traffic. And CoS 0 for everything else. The switch ports implement strict priority (SP) queuing.
What would be an advantage of enabling weighted fair queuing (WFQ) instead of SP?

A customer has a virtualized data center that uses Microsoft Hyper-V Windows Server 2012. The customer has provided this information about the hosts for the VMs:
Each host has a network (Hyper-V virtual switch) that supports VM production traffic and own two server 10G NICs
Each host has a network (Hyper-V virtual switch) that supports management traffic to the parent partition and owns two server Gigabit NICs
In each rack, the network architect plans to deploy two HP 5920 Series switches, acting as an Intelligent Resilient Framework (IRF) switch.
Which additional information does the architect need in order to plan the connection to each host?
