• Question 13:

  An architect is planning an HP Wired-WLAN solution for an office with approximately 4000 users. The solution will have 256 MSM460 APs WLAN controllers. Users must be able to roam seamlessly around the site. Which strategy meets these needs?

  A. Assign users to different VLANs based on the APs to which they connect, and distribute traffic centrally at the controller.
  B. Assign users to different VLANs based on the APs to which they connect, and distribute traffic locally at the AP.
  C. Assign all users to the same VLAN, and distribute traffic locally at the AP.
  D. Assign all users to the same VLAN and distribute traffic centrally at the controller.
  D. Assign all users to the same VLAN and distribute traffic centrally at the controller.

• Question 14:

  A network architect is designing a solution with HP products. A customer has the following requirements for controlling the management access for administrators:

  Administrators are assigned privileges when they log in based on their identity Security policies related to password complexity and password rotation, like the company's Windows domain policies, are enforced for administrator credentials The company can easily revoke the access of administrator how have the company method Administrator have a backdoor into the management interface in case network connectivity fails in any way

  Which option meets the company's requirements?

  A. Authentication to a RADIUS server with local authentication as a secondary method
  B. Authentication with a password that meets the complexity requirements and is stored locally on each device
  C. Authentication to local user accounts with TACACS+ authenticates as a secondary method
  D. Authentication to a TACACS+ server
  A. Authentication to a RADIUS server with local authentication as a secondary method

• Question 15:

  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 who need to roam seamlessly. The solution will have 256 MSM 460 APs. What is one reason for using two HP Wired- WLAN controllers for this solution?

  A. Each Wired-WLAN controller can only support 2000 users.
  B. The customer needs fast roaming, which requires a mobility solution between two controllers.
  C. Forwarding traffic trough two controllers can prevent a bottleneck due to heavy usage.
  D. Each Wired-WLAN controller can only support 128APs.
  C. Forwarding traffic trough two controllers can prevent a bottleneck due to heavy usage.

• Question 16:

  What is the preferred time for completing racking and labeling of equipment for a new implementation?

  A. After the scheduled outage has begun and initial tests have indicated success
  B. Before the scheduled outage
  C. At any time between the beginning of the scheduled outage and the point of no return
  D. At the beginning of the scheduled outage
  B. Before the scheduled outage

• Question 17:

  Refer to the exhibit.

  

  The network architect is planning network addresses for the VLANs shown. The company is using the private 10.0.0.0/8 space. Which guidelines should the network architect follow?

  A. Use a/22 subnet for each VLAN to ensure enough IP addresses for each large modular switch
  B. Implement the port isolation feature and apply several /30 subnets to each VLAN
  C. Use a/25 subnet for each VLAN to conserve the limited IP addressing space
  D. Use a /24 subnet for each VLAN for simplicity and scalability
  D. Use a /24 subnet for each VLAN for simplicity and scalability

• Question 18:

  Which two requirements of a modern data center make Spanning Tree Protocol (STP) and other traditional loop elimination protocols for that environment?

  A. Requirement to implement routing clustering virtual machines
  B. Need to consolidate traffic on a single path thorough the network
  C. Greater reliance on direct attached storage
  D. Need for faster convergence times
  E. Need to support delay-sensitive applications
  B. Need to consolidate traffic on a single path thorough the network
  E. Need to support delay-sensitive applications

• Question 19:

  A data center has a traditional three-tier network design with routing at the distribution layer. The customer is virtualizing its servers and adding technologies such as live migration of virtual machines (VMs). How well does the architecture (topology) meet the needs of the customer's changing environment?

  A. This topology is not ideal in supporting the low-latency Layer 2 communications that this environment requires
  B. This topology is ideal because it enforces consolidation of virtualized server domains
  C. This topology is not ideal because it enforces consolidation of virtualized server domains
  D. This topology is not ideal for supporting the Secure Virtualization Framework (SVF) required to protect the virtual servers
  A. This topology is not ideal in supporting the low-latency Layer 2 communications that this environment requires

• Question 20:

  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. 48 1 on floor 1 and 24 1 on floor 2
  B. 24.1 on floor 1 and 4.1 on floor 2
  C. 48 1 in all locations
  D. 24 1 in all locations
  A. 48 1 on floor 1 and 24 1 on floor 2
