In a Clos-based IP fabric, what is the primary role of a leaf device?

To act as the centralized control plane for all routing decisions in the fabric

To provide out-of-band management access to all fabric devices

To connect to servers, storage, and other endpoints, and to provide the fabric's edge services

To provide the high-speed forwarding backbone that interconnects all leaf devices

An engineer is configuring eBGP as the underlay protocol for an IP fabric. The engineer wants to ensure that the loopback interfaces of the leaf devices are advertised into BGP so that they can be used as VTEP source addresses. Which configuration is required on the leaf devices?

Configure the loopback interface as a passive BGP peer.

Configure the loopback interface with an IP address in the same subnet as the spine interfaces.

Add the loopback interface to the BGP export policy.

Enable BGP on the loopback interface using the 'set protocols bgp group underlay neighbor' command.

Which design principle is a key characteristic of an IP fabric built with a spine-and-leaf architecture?

Leaf devices are interconnected in a full mesh to provide redundancy

All devices in the fabric are connected in a ring topology to minimize cabling

Spine devices connect directly to servers, while leaf devices only connect to other leaves

Every leaf device connects to every spine device, providing multiple equal-cost paths

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 16 practice questions to prepare you well beyond it.
