D.

Does the company have an existing RADIUS server?

E.

Do users devices support Secure Shell (SSH)?

 

Correct Answer: AD

 

 

QUESTION 12

Which task does the HP Software-Defined Networking (SDN) Developer Support Description service help a customer perform?

 

A.

Replace existing virtual switches with HP-supported software-based switches.

B.

Create, test, and troubleshoot SDN applications

C.

Determine whether the company’s network infrastructure is ready for SDN.

D.

Develop a migration plan to an SDN environment.

 

Correct Answer: A

 

 

QUESTION 13

The customer wants to assign users to VLANs dynamically based on their Windows group. The company Windows Network Policy server provide the assignments. Each of the Windows groups includes between 100 to 600 users. Which issue does the architect need to resolve?

 

clip_image002

 

A.

The proposed dynamic VLANs have too many potential users for the proposed subnets.

B.

The plan for the edge ports is incorrect they should be trunk ports that support multiple VLANs.

C.

The switch-to-switch links should not carry so many VLANs.

D.

The proposed switches do not accept dynamic VLAN assignments from Windows NPS servers.

 

Correct Answer: A

 

 

QUESTION 14

The exhibit shows the topology for a network with 30 access layer switches (only two are shown).Every switch-to-switch link is a Gigabit link. Every area network (VLAN) interface runs. Open Shortest Path First (OSPF) and has the IP address shown in the exhibit. The other interface settings are defaults. The access layer switches support several more VLANs not shown in the exhibit and also run Multiple Spanning Tree protocol (MSTP) loops. What is one recommendation for enhancing convergence time and resiliency for this solution?

 

clip_image004

 

A.

Place all of the switch-to-switch links in the same VLAN.

B.

Lower the cost of the VLAN interfaces to reflect the high speed of the links.

C.

Add a BPDU filter to the VLAN interfaces shown in the exhibit.

D.

Raise the OSPF times on the VLAN interfaces.

 

Correct Answer: D

 

 

QUESTION 15

A network architect is compiling information about the total cost ownership (TCO) for a proposal. Which factors play a role in TCO?

 

A.

Cost of remediation due to a future security breach

B.

Cost of regulatory fines associated with non-compliance

C.

Cost of upgrading modules for the proposal

D.

Cost of powering the solution

 

Correct Answer: D

 

 

QUESTION 16

Customer has a virtualized data center Microsoft Hyper-V Windows Server 2012. The customer has provided this information about the Ms:

 

clip_image006Each host has a network (Hyper-V virtual switch) that supports VM productions traffic and owns two server 10G NICs.

clip_image006[1]Each host has a network (Hyper-V virtual switch) that supports management traffic to the parent partition and owns two server Gigabit NICs.

clip_image006[2]Each rack, the network architect plans to deploy two HP 5920 Series switches, acting as an Intelligent Resilient Framework (IRF) switch.

 

Which additional information does the architect need in order to plan the connections to each host?

 

A.

Whether the virtual switches use sFlow or Net Stream to load balance traffic over the NICs

B.

Whether the virtual switches use Virtual Ethernet Port Aggregator (VEPA) VLAN tagging

C.

Whether the virtual switches use generic or dynamic NIC teaming (Link Aggregation Control [(LACP)] and their hashing method

D.

Whether the virtual switches support standard Spanning Tree Protocol (STP) or Cisco Per-VLAN Spanning Tree Protocol Plus (PVST+)

 

Correct Answer: C

 

 

QUESTION 17

A customer has an 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 links that in the existing solution if an access layer uplink fails, failover occurs in less than a second.

 

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?

 

clip_image008

clip_image009

 

A.

Although the solution offers slower failover for the access layer uplinks, it is simpler and eliminates VRRP.

B.

STP eliminates the loops on the access layer uplinks and handles failover for them, which speeds convergence.

C.

Failover for an access layer uplink occurs in milliseconds, and router redundancy does not require VRRP.

D.

IRF handles loop elimination and link failover, which lets VRRP handle router redundancy more efficiently.

 

Correct Answer: C

 

 

QUESTION 18

Refer to the exhibit. A network architect has planned redundant links as shown in the exhibit. What should the network architect do to ensure that the redundant link design is truly resilient?

 

clip_image011

 

A.

Implement the features such as link aggregation, backplane stacking, and intelligent Resilient Framework (IRF)

B.

Add another link between the Layer 2 switches and the core so that up to the two links can fail

C.

Implement a feature such as bidirectional forwarding detection (BFO) on each redundant link

D.

Make sure that each HP 10508 switch is configured as a root in one Multiple Spanning Tree Protocol (MSTP) ins
tance

 

Correct Answer: C

 

 

QUESTION 19

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

 

Correct Answer: B

 

 

 

QUESTION 20

A customer prefers fixed-port switches at the campus access layer. The network architect wants to propose access layer switches simplifying network architecture and network management. Which technologies should the network architect consider? (Select two.)

 

A.

Multiple Protocol Label Switching (MPLS)

B.

Virtual Routing and Forwarding (VRF)

C.

Intelligent Resilient Framework (IRF)

D.

Backplane stacking

E.

Net Stream

 

Correct Answer: CD
