Architecting HP FlexNetwork Solutions

 

QUESTION 41

A network architect is designing a solution with HP products. A customer has the following requirements for controlling the management access for administrators:

 

clip_image002Administrators are assigned privileges when they log in based on their identity

clip_image002[1]Security policies related to password complexity and password rotation, like the company’s Windows domain policies, are enforced for administrator credentials

clip_image002[2]The company can easily revoke the access of administrator how have the company method

clip_image002[3]Administrator have a backdoor into the management interface in case network connectivity fails in any way

 

Which option meets the company’s requirements?

 

A.

Authentication to a RADIUS server with local authentication as a secondary method

B.

Authentication with a password that meets the complexity requirements and is stored locally on each device

C.

Authentication to local user accounts with TACACS+ authenticates as a secondary method

D.

Authentication to a TACACS+ server

 

Correct Answer: A

 

 

QUESTION 42

A network architect is designing a solution for a customer who wants better security on edge ports. Recently, an unauthorized individual was able to connect a snooping device to an open port (in other words, to a switch port that is active but not connected to a customer device). The customer wants to prevent this from happening again. However, the customer wants to avoid implementing 802.1X on ports because the IT staff is not prepared to deploy and manage such a solution. What is the simplest way to minimize the risk of another unauthorized connection without adding a lot of management overhead?

 

A.

Place open ports in a VLAN that is not carried on uplinks.

B.

Implement MAC lockdown (as opposed to MAC authentication) on all open ports.

C.

Apply MAC authentication to the open ports and allow only known MAC addresses

D.

Apply dynamic port access control lists (ACLs) to open ports.

 

Correct Answer: A

 

 

 

 

 

 

 

 

 

QUESTION 43

HOTSPOT

A network is choosing transceivers for switch-to-switch fiber links. Which factor affects the architect’s choice?

 

clip_image004

 

Correct Answer:

clip_image006

QUESTION 44

An architect is planning an HP Wired-WLAN solution for a customer with Voice over WLAN (VoWLAN) devices, which support 5 GHz and 2.4 GHz, and the laptops. What is a potential advantage of dual-radio 802.1n APs for this environment?

 

A.

They can load balance a single phone’s traffic between the two radios

B.

The can use 802.1n band steering to shift only the laptops to the 2.4 Ghz radio

C.

They can support a single VLAN for phones and laptops, but use load balancing to move all phones to one radio

D.

They can support a voice WLAN on one RADIO and an employee WLAN on the other radio

 

Correct Answer: D

 

 

QUESTION 45

Organizations can deploy off-the-shelf, virtualized application 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 zl Switches

 

Correct Answer: AE

 

 

QUESTION 46

A network architect has designed a two-tier topology for the campus LAN and is planning to implement routing at the core. Which requirement might cause the network architect to consider implementing routing at the access layer?

 

A.

Employees in different VLANs need to use collaboration applications to share high- resolution graphic files

B.

The solution must support an isolated VLAN for wired guest devices

C.

Employees need to be placed in dynamic VLANs, assigned by a RADIUS server in identity, so that network managers can manage the solution more easily

D.

The customer has an HP Unified Wired-WLAN solution, and wireless users need to roam seamlessly across the site

 

Correct Answer: A

 

 

QUESTION 47

Refer to the exhibit. All connections between switches are 10 Gbps. Switch is an Intelligent Resilient Framework (IRF) group with two member. Switch2 is an IRF group with two members.

 

Switch1 and Switch2 route all traffic.

 

A network architect is designing a solution for a finance company. One of the primary applications is a multicast application that delivers stock information to IP video screens across the site. The network architect is seeking a multicast solution that meets these needs:

 

Simple configuration that the customer’s IT staff can manage and troubleshoot No single point of failure for the multicast traffic

 

What is the best solution for this environment and these needs?

 

clip_image008

 

A.

Protocol Independent Multicast (PIM) Dense Mode (DM).

B.

Protocol Independent Multicast (PIM) Sparse Mode (SM) with switch 1 and switch 2 configured as candidate Rendezvous Points (C-RPs), and switch1 and Switch2 also configured as Bootstrap Router (BSRs).

C.

Protocol Independent Multicast (PIM) Dense Mode (DM) with Switch1 and Switch2 set as the DM Master Router. Switch1 has a higher MR priority for an address associated with the multicast application.

D.

Protocol independent Multicast (PIM) Sparse Mode (SM) with switch1 and Switch2 set as the static Rendezvous Points (RPs). Switch1 has a higher RP priority for an address associated with the multicast application.

 

Correct Answer: C

 

 

QUESTION 48

A network architect is designing a redundancy solution for a customer and has learned that there is a single link between two critical network components. During the past 4000 hours of operation, the link has failed twice. The customer estimates that each failure has taken two hours to resolve. Given this information, what is the availability that this link currently provides?

 

A.

Less than 99.99%

B.

99.9%

C.

99.99%

D.

99.999%

 

Correct Answer: B

 

 

QUESTION 49

When does this design benefit a virtualized data center?

 

clip_image010

 

A.

The access layer and core switches use several layers of redundancy protocols, including Multiple Spanning Tree Protocol (MSTP) at Layer 2, Virtual Router Redundancy Procotol (VRRP) at Layer 3, and Intelligent Resilient Framework (IRF) at Layer 4.

B.

The access layer and core switches can connect on link aggregation groups. VLANs can extend across these aggregations, but they are more stable and highly-available than redundant Layer 2 links that use spanning tree.

C.

The access layer switches can integrate their Intelligent Resilient Framework (IRF) capabilities with those on the core switches to create a single CLOS fabric.

D.

The core switches can implement Virtual Ethernet Port Aggregator (VEPA) to extend tunnels for virtualized traffic across the data center backbone.

Correct Answer: B

 

 

QUESTION 50

Which application might drive a company to invest in a campus LAN topology that offers lower latency for east/west?

 

A.

Enterprise-wide VoIP solution

B.

Centralized database servers hosting a rich-media client-server application

C.

External customer-facing rich-media web application

D.

Enterprise-wide collaboration using video and messaging

 

Correct Answer: A
