Midterm Prep: OpenFlow
Mastering OpenFlow: A Midterm Prep Quiz
Test your knowledge of OpenFlow and its role in Software Defined Networking (SDN) with this comprehensive midterm preparation quiz. Dive deep into the concepts, terminologies, and fun
Topics covered include:
- Flow tables and their significance
- Actions and statistics in OpenFlow
- Decoupling hardware and software layers
- Centralized intelligence in network management
OpenFlow exists at the
Northbound Interface of SDN
Southbound Interface of SDN
Driver Side
Agent Side
OpenFlow enables admins to programmatically change the flow tables in different switches and routers
True
False
OpenFlow is made up of
Group Tables
Flow Tables
Group & Flow Tables
SDN-Devices
OpenFlow provides communication between the SDN controller and SDN datapath (containing switches)
True
False
Select the four basic actions of the OpenFlow Action item in the OpenFlow table
Forward to a given port
Forward to a given switch
Forward packet as normal
Drop packet flow
Encapsulate and forward to a controller
Decapsulate and forward to a controller
Route packet through the network
In an OpenFlow network, each OpenFlow switch must contain at least 1 flow table
True
False
What does the statistics item in an OpenFlow table track?
Packets and bytes for each flow
Bandwidth usage
Network access violations
Number of hops to the destination for a flow
None of the above
OpenFlow can be run on very low end PCs running as a controller
True
False
Users can define their own flows and determine best paths by augmenting the routing protocols in OpenFlow
True
False
The OpenFlow application layer handles the business application
True
False
At this layer the hardware is decoupled from software and the control plane is decoupled from the forwarding plane.
Infrastructure layer
Application layer
Control layer
At this layer the centralization of intelligence simplifies provisioning and offers greater performance and simplification of policy management across all network devices
