Free HP HPE2-Z38 Exam Dumps Questions & Answers

A college is implementing HP Network Protector SDN Application to mitigate network attacks.
To conserve bandwidth, the college wants to prevent students from accessing social media web sites while the students are connected to the college network. However, the college wants to give professors more flexibility, while still protecting the network.
Which configuration meets these requirements?

• A.  Add the professors as exceptions to the college's blacklist.
• B.  Create different groups for students and professors, and define a customized blacklist for the student group.
• C.  Create a customized greylistfor professors.
• D.  Place all professors in one VLAN and exclude that VLAN from the flows defined for HP Network Protector SDN Application.

A network environment consists of multiple switches. Some of the switches are configured for OpenFlow 1.0, and some of the switches are configured for OpenFlow 1.3. These switches are configured to communicate with an HP VAN SDN Controller team.
What is the result of the negotiation?

• A.  All OpenFlow switches successfully negotiate to use OpenFlow 1.3 with the controller, and OpenFlow 1.0 switches ignore OpenFlow 1.3 extensions.
• B.  OpenFlow 1.3 switches successfully negotiate to use OpenFlow 1.3 with the controller, and the OpenFlow 1.0 switches fail to connect.
• C.  All switches negotiate to use OpenFlow 1.0 as the highest common version.
• D.  OpenFlow 1.3 switches negotiate to use OpenFlow 1.3, and OpenFlow 1.0 switches negotiate to use OpenFlow 1.0.

Refer to Exhibit:




A network administrator successfully creates a region on a controller team. Switch1 is part of this region. In the region, controllers are listed in this priority order: Controller 6,
Controller 8, Controller 5.
The exhibit shows the controller information on Switch 1. The switch loses its connection to
Controllers 6 and 8. What happens?

• A.  Switch1 selects Controller 8 as its new master. After a timeout period, Switch1l selects
  Controller 5 as its master.
• B.  Switch1 temporarily enters a failover mode, in which it continues to use existing flow entries but does not accept new ones. After a timeout period, it contacts first Controller 8.
  and then Controller 5.
• C.  Controller 6 communicates with other controllers to determine which of them have connectivity with the switch. Controllers advertises itself as the master for this switch.
• D.  Controller operations are suspended. Switch1 enters a failover mode, in which it continues to use existing flow entries but does not accept new ones, until it can reach at least two controllers.

Which feature of the HP Network Protector SDN Application prevents intensive DNS traffic from impacting application performance?

• A.  Meters
• B.  Rate limiting
• C.  Inspection throttling
• D.  QoS policies

What does this exhibit indicate?

• A.  The controller and switch did negotiate the OpenFlow version but could not program the flows yet.
• B.  The controller and switch do not support hybrid OpenFlow mode.
• C.  The controller and switch have not yet negotiated the OpenFlow version.
• D.  The controller and switch have negotiated the OpenFlow version as 1.0.
