A network architect is explaining Apstra reference designs to a colleague. The architect needs to describe the key components of a data center reference design in Apstra. Which statement accurately describes these components?

A reference design is a set of monitoring and alerting rules for the fabric

A reference design is a list of supported hardware models that can be used in the fabric

A reference design includes the fabric topology, device roles, underlay configuration, and overlay configuration

A reference design is a set of physical cabling instructions that must be followed exactly

A data center design requires high availability for server-to-server traffic and must support a large number of leaf switches. Which reference design should be selected?

Superspine design without leaf switches

Spine-and-leaf with redundant spine switches

A large cloud provider is building a new data center campus that will eventually support over 100,000 servers. The design will use a 5-stage Clos topology. In Apstra, what is the correct way to model this architecture?

Use the 'Multi-Fabric' feature to link multiple 3-stage fabrics into a single logical 5-stage fabric

Create a single 5-stage fabric blueprint with spine, superspine, and leaf roles

Create two separate 3-stage fabric blueprints and interconnect them with a Layer 3 link

Create a single 3-stage fabric blueprint and add the superspine devices as 'external routers'

In the context of Apstra, what is the primary purpose of a data center reference design?

To replace the need for any network monitoring or telemetry after the fabric is deployed

To serve as a mandatory hardware specification that dictates the exact vendor and model for every switch in the fabric

To provide a pre-validated blueprint that defines the structure, protocols, and operational policies for a data center fabric

To provide a static configuration file that must be manually applied to each device without modification

Part of the Apstra Design Phase 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 21 practice questions to prepare you well beyond it.
