After a large-scale agent installation, an engineer notices that several devices show as 'connected' in the Apstra UI but have no system ID assigned. What is the most likely explanation?

The devices are in a different Apstra blueprint

The devices are running an unsupported Junos version

The devices are not fully registered with Apstra

The system IDs were manually deleted

An engineer is planning to deploy a new fabric using ZTP. The engineer is concerned about system ID conflicts because the devices were previously used in another fabric. What should the engineer do to avoid conflicts?

Manually assign system IDs to each device before ZTP

Change the device hostnames before ZTP

Reset the devices to factory defaults before ZTP

Use a different ZTP server for each device

A network engineer is setting up a new data center fabric and wants to automate the installation of Apstra agents on all devices. The devices are factory-default and will be connected to the network for the first time. Which method should the engineer configure to achieve this?

Pre-configure each device with the agent image via console

Use Ansible to push the agent to each device

Manually install the agent on each device via the Apstra UI

Configure ZTP on the devices and the network

After installing the agent on a new device, an engineer checks the Apstra UI and sees that the device is listed but the agent status shows 'disconnected'. What is the most likely cause?

The device's management IP has changed

The device is not compatible with the agent

The device has a system ID conflict

The agent is not running on the device

A data center team is deploying a new leaf switch that is not factory-default; it has an existing configuration. The team wants to install the Apstra agent on this device. Which method should they use?

Copy the agent image to the device using SCP and run it manually

Manually install the agent via the Apstra UI using SSH credentials

Use ZTP by resetting the device to factory defaults

Use DHCP to provide the agent image to the device

Fabric Device Management (install Agents, System IDs) JN0-481 Practice Questions (Page 1)

Part of the Apstra Build and Deploy Phases domain, which makes up ~14% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–8 in this domain), expect 1–2 from this objective — we provide 19 practice questions to prepare you well beyond it.
