Question 2

Refer to the exhibit.

The switches in the diagram are connected to each other using two physical cables. The network consists of two HP 3800 series switches and two HP 5900 series switches. Why is only one link displayed between switches in the OpenFlow Topology diagram on the HP VAN SDN Controller?

A. Link aggregation is being used OpenFlow only displays information about the logical interface and not the physical interfaces. The HP VAN SDN Controller only displays a single link between switches B. Spanning tree is blocking one of the ports. The HP VAN SDN Controller. Only displays the active link in the OpenFlow Topology diagram. C. Link aggregation is being used. One of the Interfaces in the bundle is down, and OpenFlow has updated the HP VAN SDN Controller with this information The HP VAN SDN Controller only displays the active link in the OpenFlow Topology diagram D. The SPF algorithm used by the HP VAN SDN Controller only supports a single link between switches and blocks other links to stop loops. The HP VAN SDN Controller only displays the single active link between the switches

Question 4

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

Question 6

What are challenges when selecting traffic from UC&C soft devices for marking, in order to apply the appropriate prioritization? (Select two.)

A. UC&C traffic can share a port, mac, and VLAN combination with non-UC&C traffic. B. UC&C traffic uses well-known port numbers. C. UC&C traffic is routable. D. UC&C traffic is not peer-to-peer E. UC&C traffic uses dynamic port numbers.

Question 8

Refer to the exhibits.

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

A. The switch forwards traffic based on flow tables and does not delete unexpired 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 uses the normal forwarding process and does not delete the flow entries.

Question 9

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. Use the HP VAN SDN Controller software to digitally sign the application B. Set up an internal CA server and digitally sign the application. This will be accepted by the HP VAN SDN Controller without further configuration. C. Modify the /opt/sdn/virgo/bin'dmk sh script and include this line: Dsdn.signedJar=none D. Ensure the application is signed by a CA recognized by the HP VAN SDN Controller. E. Modify the /opt/sdn/virgo/configuration/serviceability .xml configuration file and include this line: Dsdn signedJar=none
