You are building a blueprint using Juniper Apstra and must change the cable map to match the physical environment. Where in the blueprint UI is this…

In Juniper Apstra, all modifications to a blueprint's design and topology are performed in the 'Staged' environment. The 'Active' environment is a read-only representation of the currently deployed network configuration. To change the physical cabling (the cable map), the operator must navigate to the 'Staged' tab, then select the 'Physical' view, and finally the 'Links' sub-tab. Here, links between device ports can be added, modified, or deleted to match the physical reality before committing the changes to the live network.

A. The 'Active' view is read-only and used for monitoring the current state of the network, not for making configuration changes.

C. 'Connectivity Templates' define logical server attachments, not the physical fabric links. Also, the 'Active' view is read-only.

D. 'Connectivity Templates' are used for defining how servers and external systems connect to the fabric, not for modifying the core spine-leaf cabling map.

1. Juniper Apstra User Guide 4.2.1, "Blueprints > Staged > Physical > Links". This section of the documentation explicitly details the procedure for viewing and editing device-to-device physical links within the staged version of a blueprint.

2. Juniper Networks TechLibrary, "Day One+: Deploying a Data Center with Juniper Apstra", Chapter 4: "Build Your Network Blueprint". This guide illustrates the workflow, showing that all design changes, including physical topology, occur in the 'Staged' section.
