Juniper Exam JN0-683 Topic 2 Question 5 Discussion

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.
