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

A customer is deploying a mobility solution. The IT staff is not experienced in troubleshooting issues with interference and radio frequency (RF) design, and the customer is worried that the wireless connections will not be stable or will not perform well.

Which feature of HP unified Wired-WLAN solutions addresses this customer concern?

A. Hot access controller (AC) backup

B. Wi-Fi Clear Connect integrated intrusion prevention system (IPS)

C. Remote-AP capabilities for branch offices

D. Wi-Fi Clear Connect radio resource management (RRM)

The customer plans to connect 40 Voice over IP (VoIP) phones and 8 security cameras to a switch:

The VoIP phones are Class 2 devices and require a maximum of 4.5W (draw 5w) The security cameras are Class 4 devices and require a maximum of 17W (draw 20W) The network architect is proposinga switch that supports PoE and PoE + and has a PoEPower budget of 370W.

The architect proposes the usage from of power allocation. What are the advantages and disadvantages of this proposal?

A. It allows the switch to run at a lower temperature, saving power and cooling costs, but it decreases the performance for the phones.

B. It allows the switch to connect to the PoE and PoE+ devices on cheaper copper cable, but it limits the distance between the devices.

C. It allows the switch to connect to the PoE and PoE + devices at the same time, but the customer must purchase a redundant power supply.

D. It allows the switch to support the PoE requirements without a redundant power supply, but power might be oversubscribed if conditions change.

A network architect is using the Network Traffic Analyzer (NTA) module for HP Intelligent Management Center (MC) to evaluate traffic patterns in a campus LAN environment. The network architect hopes to use this information to determine whether the current oversubscription is working well or whether the new plan to have less oversubscription.

What will provide the most useful information for this decision?

A. The peak utilization on uplinks

B. The sum of the average utilization on user edge ports

C. The peak utilization on randomly-selected user edge ports

D. The average utilization on uplinks

Organizations can deploy off-the-shelf, virtualized applications on some HP infrastructure devices Which devices support this capability? (Select two )

A. HP MSR3000 Routers

B. HP HSR6800 Routers

C. HP 7500 Switches

D. Hp 11900 Switches

E. HP 5400 z\ Switches

A customer plans to connect 40 Voice over IP (VoIP) phones and 8 security cameras to a switch:

The VoIP phones are Class 2 PoE devices and require a maximum of 45W (draw a maximum of 5w)

The security cameras are Class 4 PoE+ devices and require a maximum of 17W (draw a maximum of 20 W)

The network architect is proposing an HP 5500-48G-PoE switch, which supports PoE and PoE+ and has a PoE power budget of 370W

The customer and architect agree on the class form of power allocation

What else does the solution require?

A. A management module that is PoE+ capable

B. A redundant power supply for the switch that enhances the PoE/PoE+ budget

C. A power converter that enables the switch to provide PoE and PoE+ power at the same time

D. A 208-220V input power service

An implementation plan should include an agreed-on time for the final rollback decision. What should this decision be scheduled?

A. After the cutover to the new solution and the first set of validation tests and just before the user acceptance tests (UATs)

B. after the first steps of the rollback plan have been implemented, about ten minutes before the end of the maintenance window

C. just before the point of no return, which is calculated by subtracting the rollback time from the end of the maintenance window

D. ten minutes before the end of the maintenance window or one hour into the implementation, whichever occur first

Refer to the exhibit.

A network architect is proposing this solution to a customer. The customer network manager has a preference for Cisco VLAN Spanning Tree Plus (PVST+) because this protocol provides for fast convergence when a link fails and also provides per-VLAN load- sharing over links.

How would the network architect explain why the solution fits these requirements?

A. The MSTP component of the solution fulfills the same needs as PVST+ MSTP simply balances traffic per instance rather than per-VLAN

B. The redundant links between the switches are protected by MSTP and the built-in loop guard on HP-3800 switches. MSTP provides load-sharing and loop guard provides resiliency

C. The solution as shown provides the same load-sharing benefits as PVST+. To achieve the same resiliency benefits, the architect can add smart link to the meshed stack

D. The link aggregation between tiers provide even better resiliency and load-sharing than PVST+ while MSTP protects against accidental loops

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

The exhibit shows how two NICs on a physical server connect to two HP 5820 switches. The server supports eight virtual machines (VMs) with VMware version 5.1. The VMware standard virtual switch is bound to NIC and NIC2. This switch implements source MAC load balancing for the NIC team.

What is the proper configuration for ports 1/0/1 and 2/0/1?

A. Place the ports in a bridge aggregation group that does not use LACP

B. Place the ports in a bridge aggregation group that uses LACP

C. Enable LACP on the individual ports

D. Do not place the ports in a bridge aggregation group

Refer to the exhibit.

The customer requirements include resilience for branch communications. If anyone link fails, a branch can still reach the main office servers. In addition either one of the 5920 switches at the core of the WAN should be able to fail with branches still maintaining their connections.

What should the network architect include in the design to meet this requirement?

A. A connection directly to an ISP to each branch router, which also requires the OSPF area to become a not so stubby area (NSSA)

B. Virtual Router Redundancy Protocol (VRRP) enabled and configured in the switches in the 5920 IRF group

C. Graceful restart on the 5920 IRF group in standard IETF mode

D. A floating static route on the branch switches to the 5920 IRF group in case the OSPF solution fails
