Juniper Automation and DevOps, Associate (JNCIA-DevOps) Sample Questions (Q31-Q36):

NEW QUESTION # 31
Which type of on-box automation script is designed to run every time a user executes a configuration change?

Answer: C

Explanation:
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.
Reference:
Junos OS Automation Scripts Guide: Provides details on different types of scripts, including commit scripts, and their use cases.
Juniper Networks Documentation: Offers examples and best practices for creating and using commit scripts.


NEW QUESTION # 32
Which two programing languages would be used for on-box scripting with Junos devices? (Choose two.)

Answer: A,C


NEW QUESTION # 33
Which two statements about NETCONF layers are correct? (Choose two.)

Answer: B,C

Explanation:
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.
Supporting Reference:
Juniper Networks NETCONF Documentation: Provides a detailed breakdown of the NETCONF protocol layers and their functions.
RFC 6241: The official specification for NETCONF, which describes the layered architecture, including the operations and messages layers.


NEW QUESTION # 34
You are asked to use the REST API to retrieve interface configuration information from your Junos device. You decide to use a cURL HTTP GET command to retrieve this information.
In this scenario, which two statements are correct? (Choose two.)

Answer: C,D

Explanation:
When using the REST API to retrieve interface configuration information from a Junos device:
Data Formats (C): The information can be retrieved in XML or JSON formats. These are the two standard data formats supported by the Junos REST API for representing configuration and operational data.
Authentication (D): For each HTTP request, especially when using tools like cURL, authentication information must be included. This is typically done using basic authentication (username and password) or an authentication token.
Option A is incorrect because HTML is not a supported format for REST API data retrieval in Junos, and Option B is incorrect because SSH is not required for REST API requests; the REST API typically uses HTTP/HTTPS.
Reference:
Junos REST API Documentation: Details the data formats (XML, JSON) supported by the Junos REST API and the need for authentication.
cURL Usage with REST API: Provides examples of how to use cURL with Junos REST API, including the necessity of providing authentication.


NEW QUESTION # 35
