What is a key characteristic of a spine-and-leaf data center fabric architecture?

Leaf switches are connected only to each other

The architecture uses a single central switch for all traffic

Spine switches provide the majority of the forwarding capacity

Every leaf switch connects to every spine switch

What is a common design option for the underlay in an IP fabric?

RIP (Routing Information Protocol)

IS-IS (Intermediate System to Intermediate System)

What is a trade-off of using OSPF as the underlay protocol in an IP fabric?

OSPF cannot be used with overlays

OSPF requires careful area design to scale to large fabrics

What is a Clos network in the context of data center fabric design?

A single-switch topology that simplifies management

A ring topology that connects switches in a loop

A multi-stage switching topology that provides multiple paths between any two endpoints

A bus topology where all switches share a common cable

A network architect is designing an IP fabric for a large enterprise. The underlay will use OSPF, and the overlay will use VXLAN with EVPN. The team wants to ensure that the overlay can scale to support thousands of tenants and that the underlay remains stable. Which design decision is most critical to achieve this?

Configure OSPF with a single area to simplify the underlay

Use a dedicated loopback address for each leaf switch as the VXLAN tunnel endpoint (VTEP) source

Enable BGP route reflection only on the spine switches

Use a separate routing instance for each tenant in the underlay

Fabric Architectures JN0-1103 Practice Questions (Page 3)

Part of the Data Center Network Design domain, which makes up ~9% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~3–5 in this domain), expect 1–2 from this objective — we provide 22 practice questions to prepare you well beyond it.
