What is the primary role of a spine switch in a spine-leaf fabric?

To aggregate traffic from multiple leaves and send it to the core.

To provide a gateway for traffic leaving the data center.

To connect directly to servers and provide access to the network.

To act as the fabric backbone, interconnecting all leaf switches.

How does spine-leaf architecture optimize east-west traffic?

By providing a single high-speed path between any two leaves.

By connecting all servers to a single leaf switch.

By using a centralized controller to route all traffic.

By providing multiple equal-cost paths between any two leaves.

What is the purpose of Equal-Cost Multipathing (ECMP) in a spine-leaf fabric?

To reduce the number of routing entries in the forwarding table.

To ensure that all traffic uses the shortest path.

To load-balance traffic across multiple spine switches.

To provide a backup path in case the primary path fails.

Which statement about spine switches in a spine-leaf fabric is true?

They do not need to run routing protocols because they only forward frames.

They are typically configured with more ports than leaf switches.

They are connected to every leaf switch in the fabric.

They are responsible for connecting to servers and other end devices.

What is east-west traffic in a data center context?

Traffic between servers within the data center.

Traffic between the data center and the internet.

Traffic between the core and aggregation layers.

Traffic between different data centers.

IP Fabric Architectures (Spine/Leaf) JN0-281 Practice Questions (Page 2)

Part of the Data Center Architectures domain, which makes up ~30% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~11–18 in this domain), expect 2–4 from this objective — we provide 30 practice questions to prepare you well beyond it.
