An OpenFlow controller controls several switches that operate in pure OpenFlow mode. Based on this
scenario, what is the controller required to do?
A.
Configure a table miss entry with the Normal action for each switch.
B.
Configure flow entries to handle any loops in the topology.
C.
Use either OpenFlow 1.0 or OpenFlow 1.3, but not both versions.
D.
Ensure that each switch uses a single OpenFlow table.
Explanation:
Answer D
In a pure OpenFlow environment, flow tables are used by devices rather than routing or MAC address tables. In other words, a switch has an OpenFlow pipeline for processing packets, rather than a traditional pipeline using traditional switching mechanisms

option C (use either open flow 1.0 or 1.3 but not both)is also in line with option D
