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 applications can automate the scripting of CLI commands- that adjust QoS policies as necessary
• C.  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.
• 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 is a leader elected in an HP VAN SDN Controller team by default?

• A.  by the lowest priority value
• B.  by the highest priority value
• C.  by the highest IP address value
• D.  by the lowest IP address value

Which technology can be used in OpenFlow 1.3 that allows rate limiting of packets that are sent to the SDN Controller?

• A.  sFlow support
• B.  Slicing
• C.  Meter on IP ToS/DSCP bits
• D.  Meter table

Refer to the exhibits.


What happens when the switch shown in the exhibit loses connectivity to the HP VAN SDN Controller?

• A.  The switch uses the normal forwarding process and does not delete the flow entries.
• B.  The switch removes all flow entries and reverts to the normal forwarding process,
• C.  The switch removes all flow entries and continues to use the OpenFlow pipeline.
• D.  The switch forwards traffic based on flow tables and does not delete unexpired flow entries.

Which statement best describes software-defined networking (SDN)?

• A.  SDN is another name for OpenFlow, a protocol that lets switches handle traffic with OpenFlow tables rather than MAC forwarding tables and routing tables.
• B.  SDN allows software to leverage the network infrastructure, enabling a centralized and policy-based approach to network provisioning and traffic forwarding.
• C.  SDN allows administrators to share software, policies, templates, and applications between multiple virtual machines that are running on the same network.
• D.  SDN lets IT developers manage physical infrastructure devices directly without pre-defined templates or intermediary devices.
