Which interface configuration practice is important for stability and optimal performance in an IP fabric underlay?

Setting the MTU to the default value of 1500 bytes.

Enabling spanning-tree protocol on all fabric links to prevent loops.

Disabling spanning-tree protocol on all fabric links.

Configuring all fabric interfaces as trunk ports.

Which statement correctly describes a key design principle of an IP fabric using a spine-and-leaf topology?

Spine switches are used only for management traffic, while leaf switches handle all data traffic.

Leaf switches connect only to a single spine to simplify the underlay routing configuration.

Spine switches connect to each other to provide a backup path if a leaf fails.

Every leaf switch connects to every spine switch, and spines do not interconnect with each other.

What is the primary purpose of separating the underlay and overlay in an IP fabric design?

To allow the underlay to carry only tenant traffic and the overlay to carry only control traffic.

To enable the overlay to provide network virtualization and multi-tenancy while the underlay provides simple, scalable IP connectivity.

To eliminate the need for routing protocols in the data center.

To ensure that all switches in the fabric are in a single Layer 2 domain.

What is the purpose of configuring a loopback interface on each switch in an IP fabric?

To enable VXLAN encapsulation on the switch.

To provide a stable router ID and a consistent source address for BGP sessions.

To connect the switch to the management network.

To provide a default gateway for tenant devices.

IP Fabric Best Practices 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 14 practice questions to prepare you well beyond it.
