Questions & Answers for HP HP2-Z31

Showing 1-15 of 90 Questions

Question #1

What happens to an incoming packet that does not have a match in any of the Open Flow
tables on an HP Provision switch that operates in passive mode?

A. The packet is forwarded using legacy forwarding mechanisms.

B. The packet is forwarded to the HP VAN SDN Controller.

C. The packet is sent to the control plane of the switch.

D. The packet is dropped.

Question #2

Refer to exhibit.

Which HP VAN SDN Controller interface can a network administrator use to troubleshoot
the southbound interface of the controller and displays the output shown in the exhibit?

A. Audit Log

B. OpenFlow Monitor

C. OpenFlow Tracer

D. Dissector

Question #3

Which services does HP IMC SDN Manager provide? (Select two.)

A. Managing switch listeners

B. Updating Topology Service discovery protocol

C. Managing OpenFlow enabled SDN resources

D. Creating and maintaining flow policies

E. Managing and maintaining application awareness

Question #4

What are internal applications that are included with the HP VAN SDN Controller? (Select
three.)

A. Capacity Planner

B. OpenFlow Daemon

C. Topology Manager

D. Node Manager

E. Path Daemon

F. Time Daemon

Question #5

Which environmental component is used to handle authentication requests to the HP VAN
SDN Controller?

A. Zookeeper

B. Cassandra

C. Neutron

D. Keystone

Question #6

What is an advantage of using the HP Network Optimizer SDN application with UC&C
applications rather than just the SDN applications?

A. It enables the QoS trust boundary to be shifted to the switch.

B. It enables the UC&C Client to select the UC&C application server optimally located for them.

C. It removes the need for queuing.

D. It enables QoS verification for BYOD.

Question #7

Refer to the exhibit.

A team of HP VAN SDN Controllers has been configured. In addition, regions have been
configured. The switch shown in the exhibit has two OpenFlow sessions as follows:
Controller1 - Master
Controller2 - Slave
Controller1 is rebooted
What happens?

A. The role orchestration service detects Controller1 failure, and Controller2 becomes the master. Once Controller1 rejoins the team, it becomes the master, and Controller2 reverts to being the slave.

B. The role orchestration service detects Controller1 failure, and Controlle2 becomes the master. Once Controller1 rejoins the team, it joins as the slave controller.

C. The role orchestration service detects Controller1 failure. Controller2 becomes the master, and Controller1 becomes the slave. Once Controller1 rejoins the team. It joins as the master and Controller2 becomes the slave.

D. The role orchestration service detects Controller1 failure. Controller2 becomes the master and Controller1 becomes the slave. Once Controller1 rejoins the team it no longer communicates with the switch.

Question #8

A customer writes an internal application that does not run properly and crashes. Which
component of the HP VAN SDN Controller framework offers protection so that other
applications continue to function?

A. OSGi

B. Zookeeper

C. Cassandra

D. Keystone

Question #9

Refer to the exhibit.

A network engineer wants to use dpctl to make flow modifications directly on an HP 3800
switch flow table. Can the engineer make the changes using dpctl on the switch in the
exhibit?

A. The engineer is unable to connect to the switch directly. Dpctl requires OpenFlow 1.0, and (he switch is currently configured to use OpenFlow 1.3.

B. The engineer is able to connect to the switch directly using dpctl, but is unable to use dpctl to update the flow entries on the switch. Ovs-ofctl is required to make flow modifications when using OpenFlow 1.3.

C. The engineer is able to connect to the switch directly using dpctl. The engineer will then need to use the correct OpenFlow 1 3 syntax to make flow modifications using dpctl.

D. The engineer is unable to connect to the switch directly. Once the correct configuration is completed on the switch, the engineer will be able to connect directly and then use the correct OpenFlow 1.3 syntax to make flow modifications using dpctl

Question #10

What is a key feature of cloud computing?

A. server virtualization

B. network management virtualization

C. user self-provisioning

D. software-defined networking

Question #11

Which command installs the HP VAN SDN Controller software?

A. sudo dpkg -1 *hp-sdn-ctl

B. sudo dpkg -i hp-sdn-ctl_2.0.0.4253_amd64.deb

C. sudo dpkg -P hp-sdn-ctl_2.0.0.4253_amd64.deb

D. sudo dpkg -1 hp-sdn-ccl 2.0.0.4253 amd64.deb

Question #12

Which HP IMC SDN Manager functionally provides a detailed overview of flow entry
history?

A. SDN Manager service flow management

B. SDN Manager Open Flow device management

C. SDN Manager dashboard

D. SDN Manager flow entry management

Question #13

HP IMC provides comprehensive Fault Configuration, Accounting. Performance and
Security functionality. Which functionality does the HP IMC SDN Manager provide? (Select
three.)

A. Accounting

B. Reporting

C. Performance

D. Fault

E. Configuration

Question #14

Which OpenFlow version introduces multiple flow tables?

A. 1.0

B. 1.1

C. 1.2

D. 1.3

Question #15

A controller is able to register for asynchronous messages from an OpenFlow switch, but
when the controller attempts a flow_mod. the OpenFlow command is rejected. Which mode
is the controller in from the switch point of view?

A. Leader

B. Slave

C. Master

D. Equal
