A security team requires that all API access to Junos devices be authenticated using certificates. They are implementing the Junos REST API and need to ensure that only devices with a valid client certificate can access the API. Which configuration should be applied?

Enable HTTPS and use basic authentication.

Enable NETCONF over SSH with certificate authentication.

Enable HTTPS and configure a certificate authority (CA) to verify client certificates.

Enable HTTP and use API tokens.

A NETCONF client receives an with error-tag 'operation-failed' and error-message 'configuration database is locked'. The client is the only process using the device. What is the most likely cause?

The client is using an incorrect NETCONF version.

The client does not have permission to lock the configuration.

Another user has an active configuration session.

In the Junos XML API, what is the purpose of an RPC (Remote Procedure Call)?

To translate XML into JSON format

To establish a secure connection to the device

To request a specific operation, such as retrieving or modifying data

To define the XML schema for configuration data
