A network automation engineer is writing a script that uses the Junos REST API to reboot a device if a specific condition is met. The script must ensure that the reboot is only triggered once, even if the script is re-run. Which approach should the script use?

Use a state file on the automation server to record that the reboot was sent

Check the device's uptime before sending the reboot request and skip if uptime is low

Use a unique identifier in the reboot request and check the device's logs

Send the reboot request and ignore any errors

Which authentication mechanism is commonly used with the Junos REST API?

OAuth 2.0 with client credentials

API keys generated by Junos Space

HTTP Basic authentication with a username and password

Certificate-based authentication using client certificates

A network engineer is automating the rollout of a new configuration to multiple Junos devices. The engineer wants to ensure that if the commit fails on any device, the script stops and does not continue to the next device. The script uses the REST API. Which approach should the script take?

Check the HTTP status code of each commit response and break the loop if it is not 200

Send all commit requests in parallel and then check the responses

Ignore the HTTP status code and rely on the device's syslog

Use a single commit request for all devices
