4A0-AI1 Practice Exam Questions with Answers Nokia NSP IP Network Automation Professional Composite Exam Certification

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.

The HTTP methods that are supported by REST/RESTCONF are:

• GET: Used to retrieve a representation of a resource.
• PUT: Used to replace a resource or create it if it does not exist.
• DELETE: Used to delete a resource.
• PATCH: Used to apply a partial update to a resource.

The HTTP method ADD is not a standard HTTP method and is not supported by REST/RESTCONF.

According to the Workflow Manager User Guide from Nokia, the correct answer is C. Published. When a workflow is in the Published state, it can be executed by users who have the appropriate permissions. The Draft state is used during the creation of a new workflow, while the Deprecated state indicates that a workflow is no longer supported and should not be used. The Released state is not mentioned in the context of workflow execution.

Terminal emulation configuration is not one of the building blocks of NSP automation. The building blocks of NSP automation are Model-driven mediation, Analytics & telemetry, Multi-vendor support and Automation scripting. Model-driven mediation enables the automation of common tasks across multiple vendors and devices, and analytics & telemetry enables the gathering of critical data to ensure service quality. Multi-vendor support enables the automation of tasks across multiple vendors, and automation scripting enables the development of robust and secure automation scripts.

NSP automation is based on four key building blocks:

• Model-driven mediation: This enables NSP to communicate with various network devices and protocols using a common data model and abstraction layer. It supports YANG models, NETCONF, RESTCONF, SNMP, TL1 and CLI2.
• Analytics & telemetry: This enables NSP to collect and analyze network data using streaming telemetry, SNMP polling, syslog and other methods. It supports various analytics applications such as Network Insight, Service Assurance and Traffic Engineering2.
• Multi-vendor support: This enables NSP to manage and automate networks that consist of devices from different vendors and technologies. It supports Nokia SROS devices as well as third-party routers, switches and optical equipment3.
• Programmable APIs: This enables NSP to expose its functionality and data to external applications or systems using RESTful APIs. It supports various use cases such as network supervision, service fulfillment, fault management and workflow management2.

The value type attributes of the target-component can be assigned either a boolean or a string data type. The boolean data type can be used to indicate whether a certain attribute is enabled or not, while the string data type can be used to store textual information. Numbers and other data types are not supported.

Service Fulfilment API does not provide alarm monitoring; rather, it allows customers to quickly and easily order and provision services from a single interface, allowing for increased service agility and reduced human error.

According to the Nokia NSP Service Fulfilment API User Guide, Service Fulfilment API offers the following benefits:

A. Increases service agility by providing a programmable interface for automated service provisioning and management, allowing network operators to quickly respond to customer demands and network changes.

B. Reduces human errors by automating the service provisioning process, which minimizes the risk of manual configuration errors and improves service quality.

C. Allows multi-vendor service provisioning by providing a vendor-agnostic interface that supports different types of network equipment and technologies, reducing vendor lock-in and enabling greater network flexibility.

According to the Nokia NSP Intent Manager Application Help2, an intent has the following characteristics:

• It is stored in the database as the source of truth.
• It is an instance of an intent type, which defines the structure and logic of an intent.
• It can be created and deleted through RESTCONF API or through the Intent Manager GUI.
• It can involve services, nodes, links, paths, or any other network elements.
