file actions are NSP actions that provide access to files and folders on the NSP server. The file actions can access all directories on the NSP server, but they are restricted by the permissions of the user who runs them. For example, if a file action is run by a user who does not have write permission to a directory, the action will fail.

Workflow Manager is a tool that allows users to design and execute workflows for network automation using NSP actions and expression functions. The Workflow Manager supports data encoding/decoding formats such as JSON, CSV, XML and Base64. However, it does not support BER (Basic Encoding Rules), which is a format used for encoding data structures for transmission or storage.

This system action allows you to pause a workflow and prompt the user for input. You can use this action to confirm or deny a course of action, or to enter some data that isrequired for the workflow1.

For example, you can use nsp.user_input to ask the user if they want to continue with a service deployment or rollback.

The other options are not correct because:

std.sleep is a standard Python function that pauses the execution of a script for a specified number of seconds2.

nsp.wait is a system action that waits for an event or condition to occur before resuming the workflow1. For example, you can use nsp.wait to wait for a service activation status change or a network element alarm.

nsp.pause_before is not a valid system action. There is no such action defined in the NSP documentation1.

Comparing the actual and desired state of a network and taking action if they are not in sync. Intentbased networking is a method of managing a network by defining the intent of the network and then continuously comparing the actual and desired state of the network. If the two states are not in sync, the system will take action to bring the actual state in line with the desired one. This is different from manual processes of configuring networks or reacting to network issues. It also differs from dynamically changing the network infrastructure in real-time through one centralized location, or automatic discovery of cross domain links between IP and optical networks.

Intent is a high-level description of the desired outcome or state of the network. It allows users to specify what they want to achieve rather than how to achieve it. The intent is then translated into network configurations and policies that are used to configure the network infrastructure. Intentbased networking provides a higher level of abstraction than traditional network configuration methods, making it easier for users to specify their requirements and automate the configuration process.

Virtualization is not a characteristic of intent-based networking, but rather a technology that enables it. Virtualization is the process of creating virtual versions of physical resources, such as servers, storage, or networks1. Virtualization allows for more flexibility and scalability in network design and management, but does not imply any automation or intelligence.

The statement that best describes the Intent Manager application is: "It generates and validates the configuration of the network." Intent Manager is responsible for collecting the user's intent, verifying the user's input, and converting the user's intent into a device-specific configuration. It uses a highlevel language to abstract the network complexity, enabling the network operator to define intent in simple terms. Once the intent is defined, Intent Manager automatically generates a device-specific configuration for each network element. It then validates the intent by checking the network's current state against the user's desired intent. If there is a mismatch, it will take corrective action to bring the network to the desired intent state.

Infrastructure Lure Intents are a type of Network Intent that describe how network resources should be allocated and configured for a specific service or application.

L2/L3 VPN configuration of multiple services is NOT a characteristic of Infrastructure Lure Intents, because it is more related to service provisioning than resource allocation.
