HOTSPOT
Match the HP power saving technology with the benefit that it provides.

Explanation:
Sensors - Eliminates the risk of surge due to more aggregate power budgeting Dynamic Power Capping dynamically adjusts power to serve components Insight Control - Consolidates information about power usages and presents it for analysis

Refer to the exhibit.

The exhibit shows the uplink that the blade servers use to reach the data center LAN may carry traffic from VLAN2.4.6 or 8, or some combination.
A network architect is planning the Virtual Connect configuration. The configuration should allow the server administration to provision new server ports with the correct VLANs easily. The customer wants to create a redundant solution for the uplinks in which uplinks in both modules are used by the server blades to which they are bound.
Based on these needs, what is the correct design for the shared uplink ser (SUS) or SUSs?

• A.One SUS that has multiple networks, one for each VLAN, and is bound to the uplinks on VC module 1 as well as to the uplinks on VC module 2.
• B.One SUS has multiple networks, one for each VLAN, and is bound to the uplinks on VC module
  1. A different SUS that supports the same VLANs and is bound to the uplinks on VC module 2.
• C.On SUS for each VLAN. Half of the SUSs are bound to the uplinks on VC module 1. The other half of the SUSs are bound to the uplinks on VC module 2.
• D.One SUS that has multiple networks, for half of the VLANs, and is bound to the uplinks on VC module 1. A second SUS that has multiple networks. For the other half of the VLANs, and is bound to the uplinks on VC module2.

Refer to the exhibit.

A network architect is processing to a customer. The customer network manager has a performance for Cisco Per-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 should the network architect explain why the solution fits these requirements?

• A.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.
• B.The redundant links between the switches are protected by MSTP and the built-in loop on HP 3800 switches MSTP provides load-sharing and loop guard provides resiliency.
• C.The link aggregations between tiers provide even better resiliency and load-sharing than PVST+ while MSTP protects against accidental loops.
• D.The MSTP component of the solution fulfils the same needs as PVST+ MSTP simply balances traffic per-instance rather than per-VLAN

A network architect is designing a Multiple Spanning Tree Protocol (MSTP) solution for a network. The network architect plans to create two MSTP instances for 10 VLANs. The network architect also wants to ensure that the best paths are selected when interoperating with other spanning tree regions.
Which guideline aids in this effort?

• A.Use the appropriate cost settings for links as specified IEEE 802.1 standard.
• B.Calculate the traffic load for each VLAN and then distribute them accordingly between each MSTP instance.
• C.Set up the correct priority on the switch that you want to be root in instance 0.
• D.Place five VLANs in one MSTP instance and five in the other instance.

Refer to the exhibit.

A network architect has designed the topology in the exhibit. The Gigabit links between 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 application and have medium utilization needs.
What should the network architect do to resolve a potential issue?

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