Questions 5

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)

A. Enable BGP routing on RAGG1

B. Add a null route to 192.0.2.0/24

Questions 7

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.

Questions 9

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.

Questions 10

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

Questions 11

Refer to the exhibit. Exhibit 1

Exhibit 2

Exhibit 1 shows a simplified network topology. All infrastructure devices shown in the exhibit are successfully implementing (OSPF) on the interfaces. The exhibit also shows settings for OSPF areas. Exhibit 2 shows additional settings on IRF. The master within IRF 1 fails. Connectivity is disrupted for about one minute.

What can the network administrator do to prevent this issue occurring again?

A. Set up OSPF Bidirectional Forwarding Detection (BFD) on the routed link aggregation groups between the IRF virtual switches

B. Enable extended Link Access Control Detection Data Units (LACPDUs) on IRF 1 and IRF 4

C. On IRF 1, set up Bidirectional Forwarding Detection (BFD) Multi-Access Detection (MAD) with a dedicated link.

D. On each of the IRF virtual switches, enable opaque LSAs and set the OSPF graceful restart mode to IETF mode.

Questions 12

A company plans to use Intelligent Management Center CMC) Network Traffic Analyzer (NTA) to monitor network utilization. How do HP switches with the solution?

A. Provision switches use the NTA server as their sFlow collector. Comware switches use the NTA server as their NetStream server.

B. Provision switches use the NTA server as their sFlow collector. NetStream server, or both Comware switches use the NTA server as their sFlow collector NetStream server, or both.

C. ProVision switches use the NTA server as their sFlow collector. Comware switches as their sFlow collector, NetStream server, or both.

D. ProVision switches use the NTA server as their sFlow collector, NetStream server, or both. Comware switches use the NTA server as their sFlow collector

Interfaces = 48 and 49 Untagged VUAN = 1 Tagged VLANs = 2-4

How should the administrator complete the setup?

A. Enable link-keepalive on both interfaces in the trunk (48 and 49).

B. Enable link-keepalive on interface 48, specifying the VLAN as 1.

C. On both interfaces in the trunk (48 and 49), enable link-keepalive, specifying the VLAN as 1.

D. Enable link-keepalive on trk1
