HP HP Certifications HP0-Y52 Questions & Answers

• Question 1:

  Refer to the Exhibit.

  

  A network administrator has configured an HP Comware switch to act as the DHCP server for VLAN 12, but the switch is not responding to clients' DHCPDISCOVER messages. Based on the exhibit, what is the problem with the DHCP configuration?

  A. DHCP is not enabled globally on the switch.

  B. DHCP relay is not enabled on VLAN 12.

  C. DHCP server is not enabled on VLAN 12.

  D. DHCP server ping timeout setting is set too high.

  Correct Answer: A

• Question 2:

  A network administrator configures this command on an HP ProVision switch:

  vlan 30 ip helper-address 10.0.3.253

  The switch is able to ping 10.0.3.253. After the administrator configures the command, users in VLAN 30 report that their PCs fall to acquire addresses using DHCP.

  What should the administrator ensure?

  A. that the switch is configured with a dynamic IP routing protocol

  B. that the switch has DHCP relay functions enabled

  C. that the switch has DHCP server functions enabled

  D. that the switch has an IP address on VLAN 30

  Correct Answer: A

• Question 3:

  Which statement is true concerning spanning tree protocols and HP switches?

  A. ProVision switches use non-standard default cost values

  B. Comware switches have spanning tree enabled, by default

  C. ProVision switches, by default, auto-sense edge ports

  D. Comware switches use their serial number as the switch identifier in the bridge ID

  Correct Answer: C

• Question 4:

  In the HP Software-defined Networking (SDN) architecture, what connects the Application layer to the physical device or Infrastructure layer?

  A. HP Network Automation

  B. HP SDN Controller

  C. HP IMC Virtual Network Manager (VNM)

  D. HP IMC SDN Manager

  Correct Answer: B

• Question 5:

  Refer to the exhibit.

  

  The topology shown in this exhibit implements Multiple Spanning Tree Protocol (MSTP), where all the switches are in the same region.

  How many MSTP instances, besides the Internal Spanning Tree (IST) or instance 0, does this network need in order to have effective load sharing on the uplinks from the access switches?

  A. two

  B. three

  C. four

  D. five

  Correct Answer: D

• Question 6:

  Refer to the exhibit.

  

  A network administrator wants to create a routed topology that ensures redundant connections between User Group 1 and User Group 2. Based on this information, how many broadcast domains should the administrator create?

  A. Two

  B. Three

  C. Four

  D. Seven

  Correct Answer: B

• Question 7:

  Refer to the exhibit.

  

  All four switches run MSTP. Switch_A, Switch_B, and Switch_C are configured with this MSTP information:

  -Config name = "Region 1"

  -Revision number= 1

  -

  Instance 1 = VLANs 10, 12

  -

  Instance 2 = VLANs 11, 13

  -IST instance = VLANs 1-9, 14-4094

  Switch_D is configured with this MSTP information:

  -Config name = "Region1"

  -Revision number= 1

  -

  Instance 1 = VLANs 10, 12

  -

  Instance 2 = VLANs 11, 13, 14, 15

  -

  IST instance = VLANs 1-9, 16-4094

  Based on this information, what is the result of this MSTP configuration?

  A.

  Switch_D load balances VLAN traffic to Switch_A and Switch_B.

  B.

  Switch_D disables the links to Switch_A and Switch_B.

  C.

  Switch_D becomes a root switch.

  D.

  Switch_D causes a loop.

  Correct Answer: A

• Question 8:

  Refer to the exhibit.

  

  Examine the HP Comware switch output shown in the exhibit. Based on this output, what is a correct description of the IRF topology with which this switch is associated?

  A. This is a failed IRF daisy chain topology.

  B. This is a functioning IRF chain topology.

  C. This is a functioning IRF ring topology.

  D. This is a failed IRF ring topology.

  Correct Answer: C

• Question 9:

  Refer to the exhibit.

  

  An HP Comware switch is using its default user-interface settings. The network administrator then enters the commands shown in the exhibit. What correctly describes how an admin user must now log in?

  A. When the admin user logs in to the console port, the admin user must enter either a password of password1 or password2.

  B. When the admin user logs in using Telnet, the admin user must enter either a password of password1 or password2.

  C. When the admin logs in using Telnet, the admin user must enter a password of password1 and is given level 1 privileges.

  D. When the admin user logs in to the console port, the admin user must enter a password of password1 and is given level 3 privileges.

  Correct Answer: D

• Question 10:

  Refer to the exhibit.

  

  MSTP is configured on all switches shown in the exhibit. The Comware-1, Comware-3, and Comware-4 switches are set up for OSPF. Comware-1 and Comware-4 switches fail to achieve neighbor adjacency. The network administrator analyzes the issue and determines that MSTP is blocking on port gigabitethernet1/0/2 on Comware-1.

  Which configuration should the administrator configure on ports g1/0/1 and g1/0/2 to allow Comware-1 to form the correct OSPF adjacencies with Comware-3 and Comware-4?

  A. interface g1/0/1spanning-tree bpdu-filterquitinterface g1/0/2spanning-tree bpdu-filterquit

  B. interface g1/0/1undo stp enablequitinterface g1/0/2undo stp enablequit

  C. interface g1/0/1stp link-mode routequitinterface g1/0/2stp link-mode routequit

  D. interface g1/0/1stp bpdu-filterquitinterface g1/0/2stp bpdu-filterquit

  Correct Answer: A
