Question #21
Refer to the exhibits on the Exhibit 1 and Exhibit 2 tabs.
Exhibit 1 -

Exhibit 2 -

Network clients are configured to use the switch as their default gateway in VLAN 2. The HP Comware switch places VLAN 2 in OpenFlow instance 1. An SDN application has created the flow entry shown in Exhibit 1 to route traffic from 10.1.2.0/24 to 10.1.3.0/24. Exhibit 1 does not show the output interface for the flow.
Which output interface supports the needs of this scenario?

Which output interface supports the needs of this scenario?
- ACONTROLLER
- BANY
- CNORMAL
- DTABLE
Correct Answer:
C
NORMAL: Represents the traditional non-OpenFlow pipeline of the switch.
Can be used only as an output port and processes the packet using the normal pipeline. If the switch cannot forward packets from the OpenFlow pipeline to the normal pipeline, it must indicate that it does not support this action.

Question #23
What correctly describes the role of OpenFlow in an SDN solution?
- AOpenFlow regulates the communications among teamed SDN controllers, as well as between an SDN controller and a network infrastructure device.
- BOpenFlow integrates the SDN controller into a larger management suite, such as the one provided in the HP Helion CloudSystem solution.
- COpenFlow is an open standard technology that regulates how the SDN control plane and the application plane communicates.
- DOpenFlow is a communication protocol that an SDN controller can use to control how network devices forward traffic.

Question #25
A company is using HP Network Visualizer to monitor traffic transmitted and received by users in specific Active Directory user groups. The company wants to send traffic to a different server from the controller and have that server store the captured packets in PCAP format. How would the network administrator configure this solution to meet these requirements?
- Aby setting up a remote mirroring session
- Bby setting the destination server’s IP address in the capture session
- Cby setting up a managed remote destination
- Dby setting up a remote syslog server to receive controller log messages
Correct Answer:
B
Create Capture Session wizardStep-by-step configuration wizard to create a new capture session. The following modes of configuration are supported:
* CustomConfigure the Source/Destination IP address, Source/Destination MAC address, Port, and Protocol for capture session.
* UserConfigure the user, user group, device(s), and application for capture session.
