In a spine-and-leaf architecture, what is the typical role of the spine switches?

To connect directly to servers and storage

To run the overlay control plane and manage VTEPs

To provide a high-speed, non-blocking backbone that interconnects all leaf switches

To enforce tenant security policies

What is the purpose of BGP route reflection in an IP fabric?

To increase the number of BGP sessions for better redundancy

To reduce the number of BGP sessions required in a full mesh

To filter routes based on community attributes

To encrypt BGP updates between peers

Which protocol is often used as the underlay routing protocol in an IP fabric to scale the control plane?

RIP (Routing Information Protocol)

OSPF (Open Shortest Path First)

IS-IS (Intermediate System to Intermediate System)

What does oversubscription in a data center fabric refer to?

The number of VLANs that can be configured on a switch

The ratio of downstream bandwidth to upstream bandwidth at a leaf switch

The amount of memory allocated for routing tables

The percentage of packets that are dropped during congestion

How does ECMP improve bandwidth utilization in an IP fabric?

By compressing data before transmission

By prioritizing traffic based on QoS markings

By sending all traffic over a single best path

By distributing traffic across multiple equal-cost paths

IP Fabric Scaling JN0-683 Practice Questions (Page 1)

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.
