• B.  The CLOS fabric can dynamically shut down power to unused switch ports, proving better energy efficiency.
• C.  The CLOS fabric can integrate with a virtual switch, which is deployed in a virtualized server.
• D.  The CLOS fabric is a requirement for an Intelligent Resilient Framework (IRF) virtual switch with more than two members.
