An engineer needs to remove a specific configuration stanza from a Junos device using the XML API. The engineer wants to delete only the 'ge-0/0/1' interface configuration, leaving other interfaces untouched. Which XML operation should be used?

with the full configuration and the interface omitted

with the containing the interface and the operation attribute set to 'delete'

An engineer sends an RPC to change the hostname of a Junos device, but receives an error. The error response contains an element with and elements. What does the element typically indicate?

The specific configuration path that caused the error

A machine-readable error condition

A network team is building a custom automation tool that must manage Junos devices. They need to support both configuration changes and operational data retrieval. The tool will be used in a mixed-vendor environment, so they want to use a standardized protocol where possible. However, they also need Junos-specific extensions for advanced features. Which approach best meets these requirements?

Use only NETCONF standard operations and avoid Junos-specific RPCs.

Use NETCONF as the base protocol and use Junos XML API RPCs for Junos-specific operations.

Use RESTCONF instead of NETCONF, as it is more modern.

Use only the Junos XML API over SSH, avoiding NETCONF entirely.

What is the primary role of the XML API in Junos automation?

To encrypt all management traffic between automation tools and Junos devices

To enable programmatic access to Junos configuration and operational data using structured XML

To provide a human-readable CLI alternative for device configuration

To replace NETCONF as the primary management protocol for Junos devices

Part of the NETCONF and XML API domain, which makes up ~20% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–12 in this domain), expect 2–3 from this objective — we provide 24 practice questions to prepare you well beyond it.
