pany has implemented numerous multilayer switches that utilize FIB tables.  Which statement  is true about the Forward Information Base （FIB） table？（）

• A、 The FIB is derived from the IP routing table and is optimized for maximum lookup throughput.  
• B、 The FIB table is derived from the Address Resolution Protocol table， and it contains Layer 2  rewrite （MAC） information for the next hop.
• C、 When the FIB table is full， a wildcard entry redirects traffic to the Layer 3 engine.
• D、 The FIB lookup is based on the Layer 2 destination MAC address.
• E、 None of the other alternatives apply
