B. KVM Version 2.4.5-1 and greater

C. Parallels 8 0 and greater

D. VMware ESXi Versions 5.0.0. 5.0.1. and greater

A network integrator plans to implement the HP Network Protector SDN application in a network. What is a key consideration with regards to the OpenFlow protocol implementation and switch selection?

A. If the access switch supports PACKETIN

B. If the core switch supports PACKETIN

C. If the access switch supports FORWARD_NORMAL

D. if the core switch supports FORWARD_NORMAL

A customer wants to implement an OpenFlow solution where packets that do not match any flow entries in the OpenFlow table on the switch are not sent to the controller Rather, packets not matching should be handled normally by the switch. Which command enables this functionality on an HP 3800 series switch?

A. openflow instance sales mode active

B. openflow instance sales mode normal

C. openflow instance sales mode passive

D. openflow instance sales mode hybrid

Refer to the exhibit.

A network administrator is trying to install a new internal application on the HP VAN SDN Controller and receives the error shown in the exhibit. Which valid options are available to ensure that the application is installed successfully? (Select two.)

A. Set up an internal CA server and digitally sign the application. This will be accepted by the HP VAN SDN Controller without further configuration.

B. Use the HP VAN SDN Controller software to digitally sign the application

C. Modify the /opt/sdn/virgo/configuration/serviceability .xml configuration file and include this line: Dsdn signedJar=none

D. Modify the /opt/sdn/virgo/bin'dmk sh script and include this line: Dsdn.signedJar=none

E. Ensure the application is signed by a CA recognized by the HP VAN SDN Controller.

Refer to the exhibit.

A network engineer wants to use dpctl to make flow modifications directly on an HP 3800 switch flow table. Can the engineer make the changes using dpctl on the switch in the exhibit?

A. The engineer is unable to connect to the switch directly. Dpctl requires OpenFlow 1.0, and (he switch is currently configured to use OpenFlow 1.3.

B. The engineer is able to connect to the switch directly using dpctl, but is unable to use dpctl to update the flow entries on the switch. Ovs-ofctl is required to make flow modifications when using OpenFlow

1.3.

C. The engineer is able to connect to the switch directly using dpctl. The engineer will then need to use the correct OpenFlow 1 3 syntax to make flow modifications using dpctl.

D. The engineer is unable to connect to the switch directly. Once the correct configuration is completed on the switch, the engineer will be able to connect directly and then use the correct OpenFlow 1.3 syntax to make flow modifications using dpctl

A multicast application is used in a customer's environment that relies on IGMP. On an edge switch an Openflow 1.3 instance is configured in aggregation mode. By default, what happens to the IGMP traffic if no matching flow entry exists?

A. IGMP traffic is forwarded on the data plane.

B. IGMP traffic is forwarded to the SON Controller.

C. IGMP traffic is dropped.

D. IGMP traffic is forwarded on the control plane.
