You are deploying a new network lo support your Al workloads on devices that support at least 400 Gbps Ethernet. There is no requirement for any Layer 2 VLANs in this network. Which network architecture would satisfy this requirement?
Requirements for AI Workloads:
The scenario requires a network that supports at least 400 Gbps Ethernet and does not require Layer 2 VLANs. This setup is well-suited for a pure Layer 3 network, which can efficiently route traffic between devices without the overhead or complexity of maintaining Layer 2 domains.
Choosing the Right Network Architecture:
Option D: An IP fabric using EBGP (External BGP) is ideal for this scenario. In a typical IP fabric, EBGP is used to handle routing between spine and leaf switches, creating a scalable and efficient network. Since there is no need for Layer 2 VLANs, the pure IP fabric design with EBGP provides a straightforward and effective solution.
Options A, B, and C involve more complex architectures (like VXLAN or EVPN), which are unnecessary when there's no requirement for Layer 2 overlays or VLANs.
Conclusion:
Option D: Correct---An IP fabric with EBGP is the most suitable and straightforward architecture for a network that needs to support high-speed AI workloads without Layer 2 VLANs.
