Free Practice Questions for Nokia 4A0-AI1 Exam

An Intent is the master configuration that is synchronized with the network configuration and is stored in the database as the source of truth. Intent Types define the type of Intent, such as a network service or a configuration change, while Metadata is used to store additional information about the Intent, such as its version or author. YANG modules are used to define the data model for a particular technology.

Nokia NSP is a platform that enables management, control and automation of IP/Optical networks. It supports various levels of network automation, from static networking to autonomous networking.

The process of moving to SDN based self-regulated networking involves four stages:

Static networking: The network is manually configured and operated by human operators. There is no automation or intelligence involved.

Action-based networking: The network is partially automated by using predefined actions or scripts that are triggered by events or commands. There is still human intervention required for complex tasks or exceptions.

Adaptive networking: The network is dynamically automated by using policies, analytics and machine learning that can adjust the network behavior based on changing conditions and objectives. There is minimal human intervention required for oversight and validation.

Autonomous networking: The network is fully automated by using artificial intelligence and closed-loop feedback that can optimize the network performance and reliability without any human involvement. The network can self-heal, self-optimize and self-protect.

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 high-level 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.

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. Intent-based 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.

nsp.sr_cli is a nodal communication action that uses the network element’s NE ID to establish communication. It is one of the NSP actions and expression functions that can be used to design workflows for network automation

nsp.netconf is a nodal communication action that uses NETCONF protocol to communicate with network devices. The host input represents the management IP address of the device that is being configured by NSP. It is one of the inputs required for nsp.netconf along with username, password, port and command.

According to the NSP Network Services Platform Release 20.9 User Guide1, the attribute of the target-component that determines the component name displayed in the UI is i18n-text.

The i18n-text attribute specifies a key for a localized text string that is displayed as a label for this component in the UI. The actual text string is retrieved from a resource bundle file based on the user’s locale.

For example, if i18n-text is “Port Id”, then the UI will display “Port Id” as the component name.

SDN does not provide any advantage in terms of having network elements operate autonomously. The other three options are all advantages of SDN over traditional networks.

Network elements operating autonomously is NOT an advantage of Software-defined Networks (SDN) over traditional networks. SDN aims to centralize control plane operations and provide a global view of the network's state, enabling more efficient and flexible network management. By decoupling the control plane from the data plane, SDN separates the management logic from the forwarding hardware, allowing for centralized and programmable network control.

some of the advantages of Software-defined Networks (SDN) over traditional networks are:

Traffic programmability

Agility

Policy-driven network supervision

Network automation

Centralized controller operations

Decoupling of control plane from data plane

Global view of network’s state

orchestration is the automated configuration, coordination, and management of computer systems and software. Orchestration takes advantage of several tasks that are usually automated to create a more complex workflow.

An orchestrator is a software tool that is used to automate the configuration, coordination, and management of large virtualized systems, middleware, and services. The other three options are not related to the automated configuration, coordination, and management of large virtualized systems, middleware, and services.

Orchestrator is described as "the automated configuration, coordination, and management of large virtualized systems, middleware, and services." The orchestrator is a key component of network automation, enabling the automation and management of complex network functions across multiple devices and platforms.

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.
