Free HP HP2-Z31 Exam Dumps Questions & Answers

A company has video, voice, and collaboration applications. The company is looking for a solution that improves performance. Which benefit does software-defined networking (SDN) provide tor this company?

• A.  SDN applications can determine which traffic flows require prioritization and then program the infrastructure to prioritize these flows.
• B.  SDN establishes a loop-free, non-baking architecture using Transparent interconnection of Lots of Links (TRILL) or Shortest Path Bridging (SPF3), as the company chooses.
• C.  SDN applications can automate the scripting of CLI commands- that adjust QoS policies as necessary
• D.  SDN adds three additional priority classes, specific to voice, video and collaboration, in addition to the eight classes provided by traditional QoS mechanisms.

How does an HP Provision OpenFlow device treat packets received on a port blocked by Spanning Tree Protocol?

• A.  All Layer 2 frames are submitted to the controller for processing
• B.  Packets are not submitted to the OpenFlow pipeline for processing.
• C.  Packets are submitted to the OpenFlow pipeline for processing.
• D.  BPDU frames are submitted to The OpenFlow pipeline for processing.

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. Controller2 becomes the master, and Controller1 becomes the slave. Once Controller1 rejoins the team. It joins as the master and Controller2 becomes 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 no longer communicates with the switch.
• D.  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.

A single HP VAN SDN Controller is used to control OpenFlow enabled switches that operate in virtualization mode. An internal application is installed on the controller that redirects classified traffic to a specific VLAN. The connection between the controller and the network is lost. The HP OpenFlow enabled switches' connection interruption mode is set to standalone mode.
What is the forwarding behavior of the OpenFlow enabled switches?

• A.  Based on the timeout values, the flow entries age out, and only OpenFlow traffic is discarded
• B.  Based on the timeout values, the flow entries are removed from the flow tables, and all traffic is discarded on the switches.
• C.  All flow entries are removed, and traffic is forwarded using normal switch processing.
• D.  All flow entries are set not to age out, and the classified traffic is still redirected.

A customer has a network consisting of 90 switches running OpenFlow 1.0. High Availability is not required as a hybrid network is being used. Which license types does the customer need to purchase? (Select two.)

• A.  HP VAN SDN Ctrl 100-node E-LTU
• B.  HP VAN SDN Ctrl 50-node E-LTU
• C.  HP VAN SDN Ctrl HA E-LTU
• D.  HP VAN SDN Ctrl Base SW w/ 50-node E-LTU
• E.  HP VAN SDN Ctrl Base SWw/ 100-node E-LTU
