Which statement about the Layer 3 card on the Cisco Nexus 5500 Series Switch is true?

A.
BGP support is not provided, but RIP, EIGRP, and OSPF support is provided.

B.
Up to two 4-port cards are supported with up to 160 Gb/s of Layer 3 forwarding capability.

C.
Up to 16 FEX connections are supported.

D.
Port channels cannot be configured as Layer 3 interfaces.

Explanation:
From the Cisco NX-OS 5.1(3)N1(1) release and later releases, each Cisco Nexus 5500 Series device
can manage and support up to 24 FEXs without Layer 3. With Layer 3, the number of FEXs supported
per Cisco Nexus 5500 Series device is 8. With Enhanced vPC and a dual-homed FEX topology each
FEX is managed by both Cisco Nexus 5000 Series devices. As a result, one pair of Cisco Nexus 5500
Series devices can support up to 24 FEXs and 16 FEXs for Layer 2 and Layer 3.
