Question#1

Which two statements about NETCONF layers are correct? (Choose two.)

A. NETCONF layers use the messages layer to receive RPCs from a remote NETCONF server.

B. NETCONF layers use the messages layer to send RPCs to a remote NETCONF server.

C. NETCONF layers use the operations layer to receive RPCs from a remote NETCONF server.

D. NETCONF layers use the operations layer to send RPCs to a remote NETCONF server.

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.

Question#2

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

A. event

B. SNMP

C. commit

D. operation

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.

Question#3

Exhibit.

Referring to the exhibit, which statement about REST is correct?

A. The device is configured to allow only two simultaneous REST connections.

B. The device is configured to allow connections from the REST API Explorer

C. The device is configured to allow HTTP connections on port 3030.

D. The device is configured to allow HTTPS connections on port 3443.

Question#4

Which two programming languages have a NETCONF library supported by Juniper Networks? (Choose two.)

A. Ruby

B. Python

C. Go

D. SLAX

Explanation:
Juniper Networks supports NETCONF libraries for several programming languages, including:
Python (B): Python has a well-supported NETCONF library called ncclient, which is widely used for automating network configurations across Junos devices.
Go (C): Go also has a NETCONF library (go-netconf), which provides similar functionalities for managing Junos devices.
Ruby (A) and SLAX (D) do not have widely recognized or supported NETCONF libraries directly from Juniper Networks, making Python and Go the correct choices.
Reference: Juniper Networks NETCONF Documentation: Lists supported programming languages and libraries for interacting with NETCONF on Junos devices.
ncclient Documentation: The primary Python library for working with NETCONF.

Question#5

You want to perform a dry run on the myPlays playbook and use a custom inventory file called myRouters.ini.
Which Ansible command would you use in this scenario?

A. ansible-playbook myPlays --check -i myRouters.ini

B. ansible-playbook myPlays ―extra-vars "inventory_file=myRouters .ini"

C. ansible-playbook myPlays ―extra-vars "dry run=True" myRouters.ini

D. ansible-playbook myPlays ―limit myRouters
