A company is designing a leaf-spine fabric for a storage workload that requires high bandwidth and low latency. They plan to use 25GbE links between leaves and spines. Which design consideration is most important to meet the workload requirements?

Use a single 100GbE link between each leaf and spine.

Configure BGP route reflection on all leaves.

Use multiple 25GbE links between each leaf and spine and enable ECMP.

Deploy EVPN-VXLAN on the underlay.

A data center operator is expanding a leaf-spine fabric from 4 to 8 spine switches. Each leaf currently has a single 100GbE uplink to each spine. The operator wants to increase inter-leaf bandwidth without changing the spine count. Which action directly increases the available ECMP paths between any two leaves?

Increase the BGP local-preference on all leaf routes.

Add additional 100GbE links from each leaf to each spine and enable ECMP.

Enable EVPN-VXLAN on the overlay to load-balance traffic.

Configure BGP route reflection on the spine switches.

How do BGP confederations help scale an IP fabric?

By combining multiple ASes into a single AS to simplify routing

By enabling BGP to use OSPF as the underlying transport

By using a single router to reflect routes for the entire network

By dividing an AS into sub-ASes to reduce the number of iBGP sessions

What is a primary benefit of using EVPN in an IP fabric?

It requires a full mesh of VXLAN tunnels between all leaf switches

It eliminates the need for any routing protocol in the fabric

It only supports Layer 2 bridging and cannot handle Layer 3 routing

It provides a unified control plane for both Layer 2 and Layer 3 services

What is the primary purpose of scaling an IP fabric in a data center network?

To simplify the network by reducing the number of routing protocols used

To reduce the number of network devices required in the data center

To eliminate the need for a separate management network

To increase the number of supported end hosts and aggregate bandwidth while maintaining a predictable, uniform network design

IP Fabric Scaling JN0-683 Practice Questions (Page 4)

Part of the Layer 3 Fabrics domain, which makes up ~23% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~8–14 in this domain), expect 1–2 from this objective — we provide 32 practice questions to prepare you well beyond it.
