• Question 21:

  Refer to the exhibit.

  

  The exhibit shows a network with HP 3500 yl Series switches at the access layer and HP 8206 zl switches at the core. The customer with this solution has logged several support calls, which were eventually tracked down to spanning tree issues. How can a network architect adjust the solution to prevent the issue in the failure?

• Question 23:

  A customer has Voice IP (VoIP) phones that support Link Layer Discovery Protocol Media Endpoint Discovery (LLDP-MED). The phase need to receive their VLAN ID using this protocol. The network architect is proposing HP 5500-48G-PoE +EI switches. Each user computer connects to the phone, which then connects to the Ethernet jack. LLDP is enabled on the switch. Each Edge port is trunk port that permits VLAN 10 (the user VLAN) and VLAN 20 (the voice VLAN).

  Which other setting recommended on the edge port?

  A. The voice VLAN is enabled
  B. The PVID is set to VLAN 20
  C. LLDP Cisco Discovery Protocol (CDP) compliance enabled
  D. The LLDP voice VLAN ID is set to 20
  D. The LLDP voice VLAN ID is set to 20

• Question 24:

  Refer to the exhibit.

  

  A network architect has designed the topology shown in the exhibit. The Gigabit links between distribution layer and the core uses OM3 grade multi-mode fiber between 100m and 150m long.

  The solution is for an enterprise customer whose employees use mostly HTTP-based applications and have medium utilization needs.

  What should the network architect do to resolve a potential issue?

  A. Add more bandwidth between each pair of distribution layer switches
  B. Add more links between each modular switch at the access layer and its distribution layer switch
  C. Replace the modular switches at the access layer with switches that support stacked meshing
  D. Remove the distribution layer since it is not needed in this environment
  C. Replace the modular switches at the access layer with switches that support stacked meshing

• Question 25:

  Refer to the exhibit.

  

  A customer has the solution in the exhibit, which includes more access layer switches than are shown. Members of the customer network team mention they are considering access layer routing for a new solution to eliminate Spanning Tree Protocol (STP) and Virtual Router Redundancy protocol (VRRP). However they are concerned about meaning the routing solution. The network architect proposes a solution that eliminates STP and VRRP without requiring routing at the access layer, although the solution can use access layer routing.

  Which solution fits that description?

  A. Two HP 10500 Series, using intelligent Resilient Framework (IRF) at the core, HP S400 zl Series switches at the access layer
  B. Two HP 10500 Series switches, using Hot Standby Router Protocol (HSRP), at the core. HP 2600 Series switch at the access layer
  C. Two HP 8200 zl Series switches, using distributed Trunking, at the core. HP 5400 zl Series switches at the access layer
  D. Two HP zl Series switches, using backplane stacking, at the core. HP 5400 zl Series switches, using the backbone stacking at the access layer
  B. Two HP 10500 Series switches, using Hot Standby Router Protocol (HSRP), at the core. HP 2600 Series switch at the access layer

• Question 26:

  Refer to the exhibits. Exhibit 1

  

  Exhibit 2

  

  A customer has a existing solution, which is shown in Exhibit 1. (The solution actually includes more access layer switches than shown) in the existing solution, each access layer switch routes traffic.

  A network architect is proposing the HP FlexCampus solution shown in exhibit 2 in this proposed solution, the core intelligent Resilient Framework (IRF) virtual switch routes traffic, but the access layer switches do not.

  The customer likes that in the existing solution STP does not block either access layer uplink. The customer also likes that the existing solution does not require Virtual Router Redundancy Protocol (VRRP).

  What should the architect tell the customer about the benefits of the proposed solution?

  A. Although the IRF core must implement VRRP, STP does not block either access layer uplink, letting failover occur more quickly
  B. STP does not block either access layer uplink, and routing redundancy is provided without VRRP
  C. Although the IRF core must implement VRRP, VRRP is easier to set up than a dynamic routing protocol on all the switches
  D. STP will block one uplink on each access layer switch, but IRF enables failover to occur much more quickly
  D. STP will block one uplink on each access layer switch, but IRF enables failover to occur much more quickly

• Question 27:

  A network architect is explaining the differences between deploying two switches in an HP Intelligent Resiliency Framework (IRF) virtual switch and deploying two switches that implement standard Virtual Routing Redundancy Protocol (VRRP). Which statement correctly describes an advantage of IRF?

  A. IRF failover occurs in 3 to 4 seconds, whereas VRPF failover occurs in 10 or more seconds
  B. Unlike VRRP, which requires as least two addresses to be listed. Dynamic Host Configuration Protocol (DHCP) scopes list a single IP address for the default gateway
  C. The IRF virtual switch runs a separate routing in each member, which enhances the redundancy and reliability of the overall solution
  D. Multiple IRF members can actively route traffic for the same subnet and use the same IP address and routing control plane
  D. Multiple IRF members can actively route traffic for the same subnet and use the same IP address and routing control plane

• Question 28:

  When does an architect need to plan fast roaming for the wireless solution?

  C. When wireless devices use 802 11n and associate with APs that support both 24 GHz and 5GHz with band steering
  D. When wireless devices use voice and real-time applications, and their WLAN enforces Wi-Fi Protected Access (WPA)
  D. When wireless devices use voice and real-time applications, and their WLAN enforces Wi-Fi Protected Access (WPA)

• Question 29:

  If a network architect is planning a secure device management policy, why would administrators need to generate SSH keys on network infrastructure devices?
