Controller1 - Master
Controller2 - Slave
Controller1 is rebooted
What happens?

A) 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.
B) 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.
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 Controlle2 becomes the master. Once Controller1 rejoins the team, it joins as the slave controller.

2. Refer to the exhibit.

An SDN developer has tried use RSDoc to dis-cover the datapaths in the network. However, the error in the exhibit is displayed. Why is an error returned rather than the datapaths?

A) Packets and messages destined to the controller are dropped. Flows continue to expire according to their time-outs. This is because the default setting on HP Provision switches is fail-secure.
B) Packets and messages of new flows behave as a legacy switch or router would. Existing flows of this OpenFlow instance are removed. This is because the default setting on HP Provision switches is fail-secure.
