Which Open Flow plane is responsible for forwarding the packets?

• A.Control plane
• B.Data plane
• C.Application plane
• D.Management plane

Which protocol is used to discover directly connected links between OpenFlow devices?

• A.SNMP
• B.OF-CONFIG
• C.CDP
• D.LLDP

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. What is the result of the negotiation?

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

An HP VAN SDN Controller team is configured consisting of three controllers, using default settings.
-The first controller is configured with IP address 10.1.1.1 and priority 10. -The second controller is configured with IP address 10.1.1.2 and priority 20. -The third controller is configured with IP address 10.1.1.3 and priority 30.
Currently the third controller (IP address 10.1.1.3) is the leader device. An administrator reboots the third controller.
Which controller will be the leader once this controller comes back online?

• A.The leader role will be shared amongst all team members.
• B.the controller with the IP address 10.1.1.2
• C.the controller with the IP address 10.1.1.3
• D.the controller with the IP address 10.1.1.1

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