What is a common reason to modify an interface map in Apstra?

To change the IP addressing scheme of the network

To accommodate changes in cabling between devices

To update the device's software version

To change the management protocol used for device access

What is a common cause of interface map errors in Apstra?

Assigning an incorrect VLAN to a logical role

Mapping a logical role to an interface that does not exist on the device

Using an incorrect routing protocol in the blueprint

Configuring an incorrect management IP address

A network architect has created an interface map for a new data center fabric. The blueprint has been created, and the architect now needs to ensure that the interface map is used by the blueprint to configure the devices. What is the required step to associate the interface map with the blueprint?

Create a new device profile that references the interface map.

Reboot the devices after adding the interface map to the blueprint.

Import the interface map into the global catalog, and it will automatically apply to all new blueprints.

Apply the interface map to the blueprint and associate it with the corresponding device profiles.

A data center team is deploying a new leaf-spine fabric using Apstra. The leaf devices have 48x10GE access ports and 6x100GE uplinks. The spine devices have 32x100GE ports. The team wants Apstra to understand which physical ports on the leaves should be assigned the 'access' logical role and which should be 'uplink'. What must the team define first in Apstra to establish this mapping?

Configure the leaf devices manually via out-of-band CLI before adding them to Apstra.

Create an interface map that associates the device profile's physical interfaces with logical roles such as access and uplink.

Define a new device profile that hardcodes the role of each port.

Apply a routing policy to the blueprint that classifies interfaces based on their speed.

An engineer is troubleshooting a blueprint that will not commit. The error message points to an interface map issue. The engineer checks the interface map and notices that the 'uplink' role is assigned to ports that are defined as 'access' in the device profile. What is the most likely root cause?

The interface map has a role assignment that conflicts with the device profile's port definitions.

The cabling between the devices is not physically connected.

The device profile is not assigned to the blueprint.

The interface map is not applied to the blueprint.
