A DevOps team is building a NETCONF client to manage Junos devices. During initial session establishment, the client receives a hello message from the device listing several capability URIs. What is the correct interpretation of this message?

The device is requesting the client to enable all listed capabilities before any operations can be sent.

The device is advertising the set of capabilities it supports, and the client should only use operations and features within that set.

The device is listing the capabilities that the client must implement to establish a secure SSH transport.

The device is confirming that the client's proposed capabilities were accepted and are now active for the session.

A network team must choose between NETCONF and a REST API for automating Junos device configuration. The team requires atomic multi-step changes with rollback, but also needs to integrate with existing web-based tooling that uses JSON. Which approach best satisfies both requirements?

Use NETCONF and abandon JSON integration.

Use REST API with JSON payloads and implement custom rollback logic.

Use REST API and rely on the device's built-in transaction support.

Use NETCONF with YANG and convert responses to JSON in the orchestration layer.

A network operations team is comparing NETCONF and SNMP for managing Junos devices. They need a protocol that supports configuration management, transactional changes, and the ability to retrieve structured state data. Which protocol should they select, and why?

SNMP, because it supports rollback on configuration errors.

NETCONF, because it uses JSON for data encoding.

SNMP, because it is widely supported and has a simple data model.

NETCONF, because it supports transactional configuration changes and structured data via YANG.

What is the purpose of capabilities in NETCONF?

To define the physical interface types supported by the device

To advertise the set of operations and data models supported by the device

To specify the authentication credentials required for the session

To encrypt the NETCONF messages
