A data center is upgrading its leaf switches from a model with 48x10GE ports to a new model with 48x25GE ports. The existing interface map was created for the old model. The engineer needs to update the interface map to support the new hardware. What is the correct approach?

Create a completely new interface map from scratch and delete the old one.

Keep the old interface map and change the device profile in the blueprint to the new model.

Modify the existing interface map to reference the new device profile and adjust the port speeds accordingly.

Update the device profile to match the old interface map's port speeds.

What does interface map validation in Apstra check?

That all devices have the latest software version

That the routing protocol is correctly configured

That the blueprint has no IP address conflicts

That the interface map is consistent with device capabilities and cabling

An engineer is creating an interface map for a new fabric. The design calls for leaf devices with 48x10GE ports. The engineer wants to assign the first 40 ports as 'access' and the remaining 8 ports as 'server'. However, the engineer accidentally assigns the 'server' role to ports 1-8 and 'access' to ports 9-48. What is the most efficient way to correct this error?

Ignore the error and manually configure the devices after the blueprint is applied.

Edit the interface map and reassign the correct port ranges to the correct roles.

Change the device profile to match the incorrect mapping.

Delete the interface map and create a new one from scratch.

What is the result of applying an interface map to a blueprint in Apstra?

The blueprint automatically configures IP addresses on all interfaces

The blueprint generates a cabling diagram for the data center

The blueprint uses the interface map to assign logical roles to physical interfaces on devices

The blueprint validates the device credentials for all devices

In Apstra, what is the primary purpose of an interface map?

To map physical device interfaces to logical roles used in the design

To configure IP addressing on physical interfaces

To assign VLANs to physical interfaces

To monitor interface statistics and traffic flow

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 28 practice questions to prepare you well beyond it.
