Implementing HP Network Infrastructure Solutions Exam (HP0-Y43) Free Practice Test

Question 1

View the exhibit.

All switches shown in Exhibit 1 are HP Provision ASIC switches, which are implementing IGMP and multicast routing with PIM. Routing switch B has just received the message shown in Exhibit 2 from routing switch A . What can the network administrator assume?

A. A host connected to routing switch B has joined the 239.0.0.1 group, and routing switch B wants to join the RP tree for this group.

B. Previously, routing switch B did not require 239.0.0.1 multicasts, but it now does due to a change in topology or IGMP reports.

C. Routing switch B is responding to routing switch A's state refresh inquiry.

D. A new multicast source for 239.0.0.1 has begun to transmit in a VLAN connected to routing switch B

Correct Answer: A

Question 2

View the exhibit.

Based on the information provided in the exhibit, which IP address should this switch use as its router ID for OSPF?

A. 10.2.0.4

B. 10.1.255.2

C. 10.1.0.3

D. 10.1.1.6

Correct Answer: D

Question 3

A network uses PIM-DM to route multicast traffic. The network administrator has noticed bursts of congestion related to periodic floods of multicast traffic. How can the administrator eliminate these periodic bursts?

A. Leave PIM-DM enabled on the interfaces that face receivers, but enable PIM-SM throughout the core.

B. Enable the state refresh feature on the VLAN interfaces on which PIM-DM is enabled.

C. Decrease the PIM hello timer on VLAN interfaces on which PIM-DM is enabled.

D. Decrease the IGMP robustness variable on VLAN interfaces that connect to receivers.

Correct Answer: B

Question 4

A network administrator wants to configure a Comware switch to send HP Intelligent Management Center (IMC) sFlow samples. Where does a Comware switch direct sFlow samples?

A. To the IP address configured as the sFlowtrap receiver

B. To the IP address configured as the sFlow agent

C. To the multicast address defined for sFlow collector

D. To the IP address configured as the sFlow collector

Correct Answer: D

Question 5

A network administrator wants to configure the precise MAC addresses that are allowed to send traffic on a particular port on an HP 5400 zl Series switch. No other addresses can send traffic. Which task should the administrator complete?

A. Configure MAC lockout on the port, specifying the correct MAC addresses.

B. Configure port security on the port in configured mode, specifying the correct MAC addresses.

C. Configure MAC lockdown on the port, specifying the correct MAC addresses.

D. Configure port security on the port in dynamic mode, specifying the correct MAC addresses.

Correct Answer: B

Question 6

What are functions of Type 9 LSAs in OSPFv3? (Select two.)

A. They enable the graceful restart of the OSPFv3 process.

B. They help OSPF routing devices maintain their neighbors' state during the exchange of database information.

C. They can trigger OSPF routing devices to run the shortest path first (SPF) algorithm again. I- (?!)

D. They provide addressing information for links advertised in Type 1 and 2 LSAs.

E. They advertise the prefixes for stub networks.

Correct Answer: D,E

Question 7

A company has a network that includes HP 5800 and 12500 switches. Usage demands on the company's FTP servers have increased, causing performance issues during peak usage times. While analyzing link utilization, the network administrator noticed that the most heavily utilized links experience bursts of congestion, causing them to drop traffic. The links then experience brief periods of low utilization followed by another burst of congestion. This pattern continues periodically throughout the peak utilization time. What should the network administrator do to attempt to create a more efficient traffic pattern on these links?

A. Apply Weighted Fair Queuing (WFQ) or Weighted Round Robin (WRR) scheduling in preference to Strict Priority (SP) scheduling on the ports in question.

B. Apply a WRED table to the ports in question, optionally adjusting the table values to drop lower priority traffic first.

C. Configure inbound traffic policing policies on ports at the core, setting the CIR at about sixty percent of the ports' capacity and the PIR at about eighty percent. Apply outbound generic traffic shaping (GTS) on ports facing the core ports, setting the CIR equal to the CIR on the core ports.

D. Configure an outbound traffic policing policy on the ports in question, setting the CIR at about sixty percent of the ports' capacity and the PIR at about eighty percent.

Correct Answer: B
