Which two Cisco Nexus 3400 Series switches support 400-Gbps Ethernet ports? (Choose two.)

The Cisco Nexus 3400 Series includes specific models designed for high-density 400-Gbps Ethernet. The Cisco Nexus 3432D-S is a 1-Rack-Unit (1RU) fixed switch that provides 32 dedicated 400G QSFP-DD ports. The Cisco Nexus 3408-S is a 4RU modular chassis that supports 400G line cards, such as the N34-S-400G-L, which provides 8 ports of 400G Ethernet. Both are part of the Nexus 3400-S platform, which is built to handle high-bandwidth data center requirements.

A. The Cisco Nexus 34180YC supports port speeds up to 100 Gbps (QSFP28), not 400 Gbps.
B. Cisco Nexus 34200YC-SM is not a recognized model within the official Cisco Nexus 3400 Series product line.
E. The Cisco Nexus 3464C supports port speeds up to 100 Gbps (QSFP28), not 400 Gbps.
