Architecting HP FlexNetwork Solutions

 

QUESTION 21

Refer to the exhibits. 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?

 

Exhibit 1

Exhibit 2

clip_image004

 

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

 

Correct Answer: D

 

 

QUESTION 22

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

 

Correct Answer: D

 

 

 

 

 

 

 

 

 

 

QUESTION 23

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 n
ew 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?

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.

 

Correct Answer: B

 

 

QUESTION 24

The exhibit shows the topology for an enterprise customer LAN with an on-site data center. The Intelligent Resilient Framework (IRF) group switches supports a group of computers that very high availability to the data center. Therefore the customer has requested a backup that extends directly between the IRF group and the data center core. All of the VLAN interfaces and routed link aggregations that are shown implement Open Shortest Path First (OSPF) in a single area. Which tasks should the network architect complete to ensure that the HP 5500 IRF group selects the correct path to the data center during (Select two).

 

A.

Change the reference bandwidth to 80000 on all routing devices.

B.

Configure the VLAN 101 interfaces as silent interfaces.

C.

Change the reference bandwidth on the VLAN 101 interfaces to 1000.

D.

Set the cost on the VLAN 100 interfaces to 2Set the cost for the VLAN 101 interfaces to 80.

E.

Change the reference bandwidth on the VLAN 100 interfaces to 20000.

 

Correct Answer: CE

 

 

QUESTION 25

What is a common management problem in modern networks?

 

A.

Many vendors do not provide management tools for their devices, preventing configuration automation

B.

Management tools do not provide proper encryption and authentication options.

C.

Many technologies and solutions require their own management interfaces, resulting in too much complexity.

D.

Administrators spend so much time planning for the future that they cannot react to current problems.

 

Correct Answer: D

 

 

QUESTION 26

A network architect is planning an update of the server access layer in a data center. Currently, the access layer switches have 10G links to distribution layer switches. In the new solution, HP 5930 Switches act as top of rack (ToR) switches with 40G links to core switches. Which factor must the network architect consider when designing solution?

 

A.

Whether the data center cabling provides enough fiber strands to the racks to support the 40G links

B.

Whether the new switches 40G transceivers are on the chassis front or back, the transceivers must be on the same side as servers air outtakes

C.

Whether the servers connecting to the new switches use Ethernet Virtual Bridging (EVB)/Virtual Ethernet Port Aggregate (VEPA), which is not compatible with 40G

D.

Whether the servers connecting to the new switches have NICs that support Converged Enhanced Ethernet (CEE)

 

Correct Answer: A

 

 

QUESTION 27

A network architect is planning a guest solution for a group of ports in a conference room. Guests should have access to the Internet only. The company wants a simple solution and prefers not to burden visitors with login requests. Which solution would best meet the company’s requirements for a gust network?

 

A.

Place the ports in a black-hole VLAN that is not carried on Switch-to-Switch links. Apply a dynamic VLAN for guests who pass web authentication to a server that allows MAC registration

B.

Place the guest ports that is allowed access only to the internet. Optionally configure port isolation.

C.

Apply MAC lockdown to the guest ports. Configure switches to place unknown MAC addresses in a VLAN with access only to the internet

D.

Apply web authentication to the guest ports. Use the built-in guest accounts for HP switches to authenticate the users
