Which two statements about NETCONF layers are correct? (Choose two.)
NETCONF (Network Configuration Protocol) is a standard protocol defined for managing network devices. NETCONF operates in a layered architecture, which includes the following key layers:
Operations Layer: This layer deals with the actual operations like <get-config>, <edit-config>, <copy-config>, and others. It receives RPC (Remote Procedure Call) requests from a remote NETCONF client and processes these requests.
Messages Layer: This layer is responsible for encoding the RPCs and sending them over the network. It handles the communication between the NETCONF client and server, ensuring that the RPC messages are correctly formatted (usually in XML) and transmitted.
Statement B is correct because the Messages layer is responsible for sending RPCs to a remote NETCONF server.
Statement C is correct because the Operations layer is where the NETCONF server receives and processes the RPCs sent by the client.

What will determine which data serialization format is used for interfacing with a system?
Which development model is the classic approach to software development?
What is the default port for NETCONF connections over SSH?

Which type of on-box automation script is designed to run every time a user executes a configuration change?
In Junos OS, a commit script is an on-box automation script that runs every time a configuration change is committed. Commit scripts are used to enforce configuration policies, validate configuration changes, or make automatic adjustments to configurations when certain conditions are met.
Commit Script (C): Executes automatically during the commit process, ensuring that the new configuration adheres to specific rules or conventions before it is applied to the system.
Event, SNMP, and operation scripts are used for other purposes in Junos automation but do not run automatically with every configuration change.

Juniper Networks Documentation: Offers examples and best practices for creating and using commit scripts.
