A fabric has a leaf device that is in an 'error' state. The Apstra event log shows 'LLDP probe failed' for the device. The device is reachable via SSH and its management interface is up. What is the most likely root cause?

The device's BGP sessions are down

The LLDP neighbor information on the device does not match the expected topology in Apstra

The device has been rebooted and is still booting up

The device's management interface is down

In Apstra, what does a device state represent?

The performance metrics of a device over time

The operational status of a managed device within the fabric

The configuration version of a device

The physical location of a device in the data center

Which event would typically trigger a device state transition from 'active' to 'error'?

A device fails to apply a configuration change

A device is gracefully shut down for maintenance

A device is added to the fabric for the first time

A device is removed from the fabric

An administrator is reviewing the device states in an Apstra blueprint and sees that a leaf switch is in the 'error' state. What is the most likely reason for this state?

One or more probes have failed, indicating a problem with the device or its configuration

The device is operating normally but has a minor warning

The device has been removed from the blueprint

The device is not yet configured and is waiting for initial deployment

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 24 practice questions to prepare you well beyond it.
