A data center operator is designing an IP fabric to support a large number of tenants, each with multiple VLANs. The underlay will use BGP, and the overlay will use EVPN-VXLAN. What is the primary role of the underlay in this design?

To provide Layer 2 connectivity between all servers in the fabric.

To isolate tenant traffic using VLANs.

To advertise tenant MAC addresses across the fabric.

To provide IP connectivity between switches, enabling the overlay to function.

A data center architect is designing a new IP fabric for a high-performance computing (HPC) environment that requires extremely low latency and high throughput for east-west traffic. The design will use spine-and-leaf topology. Which placement and design choice is most critical to meet the latency requirements?

Place spine switches in the middle of the data center and connect each leaf to every spine with equal-cost links.

Use a single spine switch to reduce the number of hops.

Place all servers in the same rack and connect them to a single leaf switch.

Use a 3-tier architecture with core, aggregation, and access layers.

How does an overlay network interact with the underlay in an IP fabric?

The overlay provides physical connectivity for the underlay

The overlay replaces the underlay routing protocols

The overlay and underlay operate independently without interaction

The overlay encapsulates tenant traffic and transports it across the underlay

A data center operator is designing a new IP fabric to support both traditional VM workloads and containerized microservices. The VMs require Layer 2 adjacency across racks, while the containers only need Layer 3 connectivity. The design must minimize the number of protocols and simplify operations. Which approach is most appropriate?

Use a pure Layer 3 fabric with VXLAN and EVPN to provide both Layer 2 and Layer 3 services.

Use a traditional spanning-tree-based Layer 2 fabric for VMs and a separate routed fabric for containers.

Use OSPF for the underlay and static routes for the overlay.

Use a single OSPF instance for both underlay and overlay, with VLANs for tenant isolation.

In a spine-and-leaf IP fabric, what is the recommended placement of spine switches to ensure predictable latency and scalability?

In a central aggregation layer between leaf switches and the core

As a set of switches that each connect to every leaf switch, forming a uniform layer

At the top of each rack, directly connecting to servers

As a full mesh of switches connecting every leaf to every other leaf

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.
