Question 2

Refer to the exhibit.

A team of HP VAN SDN Controllers has been configured. In addition, regions have been configured. The switch shown in the exhibit has two OpenFlow sessions as follows:
Controller1 - Master
Controller2 - Slave
Controller1 is rebooted
What happens?

A. The role orchestration service detects Controller1 failure. Controller2 becomes the master, and Controller1 becomes the slave. Once Controller1 rejoins the team. It joins as the master and Controller2 becomes the slave.

B. The role orchestration service detects Controller1 failure, and Controlle2 becomes the master. Once Controller1 rejoins the team, it joins as the slave controller.

C. The role orchestration service detects Controller1 failure. Controller2 becomes the master and Controller1 becomes the slave. Once Controller1 rejoins the team it no longer communicates with the switch.

D. The role orchestration service detects Controller1 failure, and Controller2 becomes the master. Once Controller1 rejoins the team, it becomes the master, and Controller2 reverts to being the slave.

Question 4

Refer to the exhibit.

The topology shown in the exhibit has the following characteristics:
*The Open Flow enabled switches are running in virtualization mode with member VLAN 10
*All the switches in the topology share the same VLANs.
*All the VLANs are tagged on all the links.
*Each OpenFlow domain is controlled by its own controller and is making independent decisions
*Every switch within the topology has PVST enabled only on VLAN 10
The networking team implementing OpenFlow reports that there are communication problems between the OpenFlow domains. What could be the cause of this communication problem?

A. OpenFlow networks that communicate must use different VLANs.

B. A loop has been formed.

C. OpenFlow requires a dedicated out-of-band management network

D. This is an unsupported topology.
