A data center fabric uses eBGP as the underlay. A leaf switch is advertising a summary route for its loopbacks, but the spines are not installing the summary route. The engineer verifies that the summary route is in the leaf's routing table. What is the most likely cause?

The spines have a higher local preference for the summary route

The summary route is not in the BGP table

The import policy on the leaf rejects the summary route

The export policy on the leaf does not allow the summary route

In a spine-and-leaf data center architecture, what is the primary role of IP fabric routing?

To segment tenant traffic using VLANs and VXLAN encapsulation

To provide a Layer 2 loop-free topology using Spanning Tree Protocol

To establish a scalable, loop-free Layer 3 underlay that provides optimal path selection between leaf and spine switches

To replace the need for any routing protocol by using static routes on all switches

What is a common method used by Juniper switches to load balance traffic across ECMP paths in an IP fabric?

Load balancing based on the packet size

Hash-based load balancing using packet header fields

Per-packet round-robin forwarding

Random path selection for each packet

IP Fabric Routing 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 27 practice questions to prepare you well beyond it.
