Junos PyEZ uses YAML (YAML Ain't Markup Language) files to define the format for tables and views when working with operational and configuration data. YAML is a human-readable data format that is commonly used for configuration files, making it suitable for defining data structures in PyEZ.

Option B (YAML)is correct because PyEZ tables are defined using YAML files.

Options A (JSON), C (txt), and D (IXML)are incorrect in this context, as YAML is the standard format used.

Junos PyEZ Tables Documentation:Explains the use of YAML files for formatting tables and views in Junos PyEZ.

In Junos, theJET (Junos Extension Toolkit)API supports direct modification of theEphemeral database. The Ephemeral database is a temporary configuration database used in Junos OS, allowing for changes that do not persist after a reboot unless explicitly committed to the permanent configuration.

JET API: Allows for high-performance interactions with Junos, including the ability to make changes to the Ephemeral database, which is useful for temporary configurations, dynamic policies, and other operational tasks.

Other options like WebSocket, SOAP, and REST do not provide direct access to the Ephemeral database in Junos.

Juniper Networks JET Documentation: Details how JET API interacts with the Ephemeral database.

Junos Automation and DevOps Documentation: Discusses the use of JET for automation and dynamic configuration.

The NETCONF protocol, used for network management, utilizes XML for encoding the RPC (Remote Procedure Call) requests and responses. XML is chosen because of its flexibility and ability to represent hierarchical data structures, making it well-suited for representing network configurations and states.

Option Bis correct because XML is the standard format used for NETCONF RPC payloads.

Options A (YAML), C (JSON), and D (HTML)are incorrect because these formats are not used by NETCONF for its RPC payloads.

RFC 6241 - NETCONF Protocol:This RFC describes the use of XML for encoding NETCONF messages.
