  A. The Web server must be able to ping IP addresses in the Web-Auth subnet on each switch.

  B. The server must have a certificate that is signed by a CA certificate loaded on the access layer switches.

  C. The login pages must exactly match template pages provided by HP. with the exception of the logo image.

  D. The login pages must use specific names, which are documented in switch manuals.

  Correct Answer: A

• Question 32:

  What distinguishes an HP switch with a CLOS fabric from an HP switch with a crossbar fabric?

  A. The CLOS fabric can integrate with a virtual switch, which is deployed in a virtualized server.

  B. The CLOS fabric is a requirement for an Intelligent Resilient Framework (IRF) virtual switch with more than two members.

  C. The CLOS fabric can dynamically shut down power to unused switch ports, proving better energy efficiency.

  D. The CLOS fabric can dynamically load-balance internal traffic over many paths, helping the switch support 40G/100G.

  Correct Answer: D

• Question 33:

  HP Comware Switch 1 connects to switch 2 on GigabitEthernet 1/0/1. Swutch 2 implements an inbound rate limit of 600 Mbps. The network administrator wants switch 1 to buffer traffic that exceeds the Switch 2 rate limit of 600 Mbps and send the traffic at 600 Mbps. All traffic has the same 802.1p priority and is forwarded in priority queue 2. What should the administrator apply to the Switch 1 interface GigabitEthernet 1/0/1?

  A. A line rate limit of 600 Mbps on queue 2

  B. A QoS policy with a classifier that matches all traffic and a CAR behavior that sets a CIR of 600 Mbps

  C. A weighted random early discard (WRED) table with a limit of 600 for queue 2

  D. A traffic shaping rate limit of 600 Mbps on queue 2

  Correct Answer: D

• Question 34:

  Two HP 10500 Series Switches connect on a 10G fiber link. One of the two fibers in the link breaks, and a broadcast storm occurs. How could a network administrator prevent a problem like this from happening again?

  A. Configure Device Link Detection Protocol (DLDP) on both sides of the link.

  B. Use Rapid Per VLAN Spanning Tree Plus (RPVST+) instead of Multiple Spanning Tree Protocol (MSTP).

  C. Implement sFlow or NetStream on both sides of the link, setting the collector to an Intelligent Management Center (IMC) server.

  D. Add another 10G link and create a link aggregation group on each switch that includes both links.

  Correct Answer: A

• Question 35:

  Refer to the exhibit.

  

  A network administrator up a remote mirroring on the HP Comware switches in the exhibit. The administrator must define several port while entering mirroring- group commands on these switches. Which port should be the reflector port (sometimes called monitor-egress port)?

  A. Switch 1, G1/0/2

  B. Switch3, T1/0/4

  C. Switch 1, T1/0/25

  D. Switch 1, G1/0/1

  Correct Answer: B

• Question 36:

  A company needs a simple authenticate solution for guests. The HP Comware access layer switches will implement portal authentication (or Web-Auth). The network administrator wants the switch to host the login web page on an IP address that not used for any other purpose.

  What should the administrator do to accomplish this goal?

  A. Set the IP address when defining the local portal server, and create a loopback interface for the address

  B. Create RADIUS scheme that specifies this IP address for the authentication server. Select this scheme for portal authentication in the default domain

  C. Create a layer 3 interface for the guest VLAN and assign the desired IP address. Activate local portal authentication on this interface.

  D. Set the IP address when defining the local portal server, and the switch automatically begins using that address.

  Correct Answer: C

• Question 37:

  Refer to the exhibit.

  

  These three routers are currently configured for BGP. They do not apply any routing policy in terms of BGP on routes or attributes advertised to an received from peers. How can the network administrator for Router 1 cause Router 1 to advertise 192.0.2.0/24 to Router 2 and Router 3?

  A. Enable BGP routing on RAGG1

  B. Add a null route to 192.0.2.0/24

  C. Apply route policy 1 as an inbound policy for both peers

  D. Apply route policy 1 as an outbound policy for both peers

  Correct Answer: B

• Question 38:

  Refer to the exhibit.

  

  An HP Comware Switch connects to Voice over (VoIP) phones. The phones connect to user's computes, so each switch port connects a computer and a phone. These are the specifications:

  The VLAN for data traffic is VLAN3

  The VLAN for traffic VoIP is VLAN11

  The phones support Link Layer Discovery Protocol (LLDP) Media Endpoint Detection (MED).

  The network administrator wants to use LLDP-MED to advertise the voice VLAN ID and priority settings to the phones. The phones will then send tagged traffic in that VLAN. The switch should not check the incoming traffic's MAC address

  against its voice OID list. The exhibit shows the applicable switch port configuration.

  Which additional step must the administrator complete to accomplish this?

  A. Enable voice VLAN 11 (voice vlan 11 enable)

  B. Change the port to trunk mode (port link-type trunk)

  C. Enable LLDP compatibility with Cisco Discovery Protocol (CDP) (lldp compliance admin-status cdp txrx)

  D. Enable the port to advertise voice VLAN 11 with LLDP (lldp voice-vlan 11)

  Correct Answer: D

• Question 39:

  A company uses 802.1X authentication to force users to authenticate to connect to the network. The company uses HP IMC User Access manager (UAM) as the RADIUS server. The company wants to assign users to VLANs based on their identity. For example, contractor should be assigned in VLAN 20. Assume that VLANs are extended correctly across the network infrastructure.

  Where does a network administrator configure the VLAN policy?

  A. In the access device configuration UAM

  B. In local-user accounts for contractors, which are configured on access layer switches

  C. In an authorized VLAN list, which is applied to access layer switches edge ports

  D. In an access rule on UAM, which will be selected in the contractor service policy

  Correct Answer: D

• Question 40:

  How does virtual output queuing (VoQ) help switches avoid head-of-line blocking and enhance throughput?

  A. It divides each port ingress queue into different queues based on the priority and egress port of each packet

  B. It establishes a matrix of connections to multiple cross-bar switches within the switch backplane

  C. It considers traffic congestion, queues traffic, and informs the ingress port when it can use the crossbar

  D. It allows the ingress port to fragment packets and send the fragments in multiple queues over different crossbars

  Correct Answer: A
