A data center fabric currently has 4 spines and 20 leaves. The organization expects a 50% increase in server traffic over the next year. To scale the fabric while minimizing the impact on existing operations, which approach is most effective?

Increase the link speed between spines and leaves from 40 GbE to 100 GbE.

Add more leaf switches and connect them to all existing spines.

Replace all leaf switches with higher-capacity models.

Add more spine switches and connect them to all existing leaves.

A network team is deploying a new IP fabric and wants to ensure that the design is easy to operate and troubleshoot. Which best practice should be followed?

Disable all logging to reduce overhead.

Use different routing protocols on each leaf to provide diversity.

Use a different configuration template for each switch to avoid conflicts.

Use a consistent naming convention for all switches and interfaces.

A large enterprise is deploying a new IP fabric with 64 leaf switches and 8 spine switches. The design requires fast convergence and support for ECMP to utilize all available paths. The network team is familiar with OSPF but is considering BGP for the underlay. Which routing protocol choice is most appropriate for this underlay?

BGP with a private AS number per leaf and a common AS for spines.

RIP for simplicity, since the fabric is small.

OSPF with multiple areas to reduce the routing table size.

Static routing with default routes to the spines.

A network engineer is troubleshooting an IP fabric where BGP sessions between leaves and spines are flapping. The underlay uses eBGP with a private ASN per leaf. The engineer notices that the BGP timers are set to aggressive values. What is the most likely cause of the flapping?

The BGP keepalive timer is too short, causing the session to be reset frequently.

The BGP update timer is too long, delaying route advertisements.

The BGP hold timer is too long, causing sessions to stay up even when the link is down.

The BGP connect timer is too short, causing rapid reconnection attempts.

A small data center is deploying a spine-and-leaf fabric with 2 spines and 8 leaves. The design must be resilient to a single spine failure without causing significant traffic loss. Which placement and redundancy strategy should be used?

Place spines in the same rack and connect each leaf to both spines, but use a single link for redundancy.

Place both spines in the same rack and connect each leaf to only one spine to save ports.

Use a single spine and rely on leaf-to-leaf links for redundancy.

Place spines in different racks and connect each leaf to both spines using ECMP.

IP Fabric Implementation JN0-1103 Practice Questions (Page 1)

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 23 practice questions to prepare you well beyond it.
