Question: 1

Virtual Connect Flex-10 technology can divide a single 10GbE port into how many individual network connections?

A. 2

B. 4

C. 5

D. 10

Answer: B

Explanation:

HP Virtual Connect (VC) Flex-10 technology is a hardware-based solution that lets you split a 10 Gb/s server network connection into four variable partitions.

Question: 2

A network architect is planning an HP MultiService Mobility for a customer. The solution is intended to provide wireless access for employees various branch locations. The solution includes two MSM760 Premium Mobility Controllers, which are deployed at the main office, and 60 MSM 460 Access Points (APs), which are deployed at branches (three at each branch).

The network architect is controlling information about the branch routers and firewalls. What is the one reason that the architect needs this information?

A. To determine whether to add bandwidth to the WAN link because wireless traffic must be tunneled to the controller regardless of its ultimate destination.

B. To determine whether the branch routers support the type of tunnel that is required to connect the MSM APs to the controller.

C. To determine whether the managers needs to open ports on the branch firewalls to allow communications between the APs and the MSM Controller.

D. To determine whether the branch routers need to provide a virtual private gateway (VPN) solution to secure the wireless traffic.

Answer: A

Question: 3

Which switch is best suited to act at the edge of a medium to large HP FlexFabric solution?

A. 10500

B. 5500

C. 9500

D. 5830

Answer: D

Explanation:

D: The HP 5830AF Switch Series is a family of high-density 1 GbE top-of-rack data center and campus switches that are a part of the HP FlexFabric solution module of the HP FlexNetwork architecture. The two models, the 5830AF-48G and 5830AF-96G switches, are ideally suited for deployments at the server access layer in medium-sized and large enterprise data centers and campus networks.

Note: 5830 switches are typically in the edge, not the core.

Note 2: Flatten the network with Intelligent Resilient Framework

Intelligent Resilient Framework (IRF) overcomes the limitations of legacy spanning tree designs by providing rapid failover for delay-sensitive, mission-critical applications and dramatically improving network utilization and performance in the network core.

By deploying IRF in conjunction with highly-scalable 12500 switches in the core and 5830 GbE and 5820 10 GbE series switches in the access layer - IT can completely eliminate the requirement for a dedicated aggr egation layer as they scale-out data centers, and enjoy the benefits of large Layer 2 domains with increased network uptime and simplified management.

IRF is an innovative HP switch platform virtualization technology that allows customers to dramatically simplify the design and operations of their data center and campus Ethernet networks.

Question: 4

A network architect is planning the products that will interconnect a main site campus LAN, Branches, and data center (located at the different site from the main campus). Which customer requirement would cause the network architect to change HP enterprise-class modular routers as opposed to deep-buffer 10G routing switches for this solution?

A. The need for a fully redundant solution with two devices as a team

B. The need for thousands of routers in the routing table

C. The need for high speed routing

D. The need for WAN connections that use T3/E3/J3

Answer: D

Question: 5

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. Replace the modular switches at the access layer with switches that support stacked meshing.

B. Add more bandwidth between each pair of distribution layer switches and the core switches.

C. Add more links between each modular switch at the access layer and its distribution layer switch.

D. Remove the distribution layer since it is not needed on this environment.
