Cisco Nexus 3400 Series Switches

CD.

The Cisco Nexus 3400 Series switches are high-performance, low-latency switches designed for data center applications. These switches offer a range of port speeds, including 10 Gbps, 25 Gbps, 40 Gbps, 50 Gbps, and 100 Gbps. Additionally, some models in the series also support 400-Gbps Ethernet ports.

The two switches in the Cisco Nexus 3400 Series that support 400-Gbps Ethernet ports are:

A. Cisco Nexus 34180YC: This switch is a 1RU fixed-configuration switch that supports 48 10/25-Gbps SFP+ and 6 100/400-Gbps QSFP-DD ports. It is designed for high-density 10/25/100-Gbps and 400-Gbps data center spine and leaf deployments.

B. Cisco Nexus 34200YC-SM: This switch is a 2RU fixed-configuration switch that supports 48 10/25-Gbps SFP+ and 6 100/400-Gbps QSFP-DD ports. It is designed for high-performance 10/25/100-Gbps and 400-Gbps data center spine and leaf deployments.

Therefore, options A and B are the correct answers to the question.

C. Cisco Nexus 3432D-S is a 1RU switch that supports up to 32 ports of 40/100-Gbps QSFP28, making it suitable for high-performance data center applications.

D. Cisco Nexus 3408-S is a 2RU switch that supports up to eight slots for 100-Gbps or 400-Gbps modules, making it suitable for data center aggregation and core deployments.

E. Cisco Nexus 3464C is a 2RU switch that supports up to 64 ports of 100-Gbps QSFP28, making it suitable for high-density data center deployments.

However, options C, D, and E do not support 400-Gbps Ethernet ports and are therefore incorrect answers to the question.
