Which benefit is directly associated with scaling an IP fabric in a data center?

It reduces the number of IP addresses required for the underlay

It allows the network to grow without requiring a complete redesign

It guarantees zero packet loss during any link failure

It eliminates the need for network monitoring

Which mechanism is commonly used to scale an IP fabric by providing multiple equal-cost paths for load balancing?

Network Address Translation (NAT)

A data center architect is designing a new IP fabric. They need to scale the fabric to support thousands of virtual networks and MAC addresses. They plan to use a simple underlay with only loopback addresses and iBGP. Which scaling approach should they use for the overlay?

Add more spine switches to increase ECMP paths.

Increase the MTU on all underlay links.

Use EVPN-VXLAN to carry MAC and IP routes over the underlay.

Configure BGP confederations on the underlay.

A data center operator is designing a fabric where each leaf has two 40GbE uplinks to each of two spines. They want to ensure that a single link failure does not cause traffic to be dropped. Which design feature provides this redundancy?

BGP route reflection on the spines.

Which element is part of the overlay network in an IP fabric?

IP addresses assigned to loopback interfaces

IP Fabric Scaling JN0-683 Practice Questions (Page 6)

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.
