4A0-AI1 Nokia NSP IP Network Automation Professional Questions and Answers

The character used to separate the attributes of a Target with multiple attributes is /.

For example, a Target with multiple attributes could be: /network=IP/service=VPN.

An integrated control plane and data plane is NOT an advantage of Software-Defined Networks (SDN) over traditional networks. SDN separates the control plane from the data plane, enabling more efficient and flexible network management. By centralizing the network logic at the controller level, applications can communicate directly with the controller, allowing for greater agility in automating, monitoring, and provisioning network infrastructure.

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

According to the NSP Network Services Platform Release 20.6 Intent Manager Application Help1, an intent type consists of four components: general metadata, target, YANG model and script. The metadata in the meta-info.Json file appears in the General and Resources panels of the Edit Intent Type window

According to the NSP Intent Manager Application Help1, an intent type consists of four components: general metadata, target, YANG model and script. The resources component is used to store files that are required by the script component1. Therefore, A. Framework files is NOT a category of files found in the intent-type resources directory.

According to the Mistral Workflow Language (v2) documentation1, which is one of the technologies that can be used in a NSP workflow2, flow control attributes are used to define how a task behaves depending on its execution status. The valid flow control attributes are on-success, on-error, on-complete, and on-cancel1. Therefore, the correct answer is A.

The Nokia NSP is an IP network automation platform that provides a unified view of the network and enables end-to-end automation of IP networks. It is designed to be vendor-agnostic and can manage a wide range of equipment from various vendors, making it the Source of Truth for the entire network. It uses NETCONF and YANG to provision the network and can act as a Path Computation Element (PCE).

Nokia NSP is a network automation platform that supports multi-vendor network infrastructure. It acts as the "Source of Truth" for the network, uses NETCONF and YANG to provision the network, and can act as a Path Computation Element (PCE) to optimize traffic flow across the network. It supports a wide range of network devices, including those from third-party vendors, making it a flexible and vendor-agnostic solution for network automation.

some of the statements about the Nokia NSP are:

• It is a platform that provides service automation and network optimization across multiple network layers and domains.
• It uses NETCONF and YANG to provision the network and supports various protocols such as BGP-LS, PCEP, SNMP, etc.
• It can act as a Path Computation Element (PCE) and provide end-to-end path computation for traffic engineering applications.
• It can manage equipment from multiple vendors and supports open interfaces and standards.

NSP Workflow Manager (WFM) is a module that allows users to create and execute automated procedures using NSP or third-party APIs. A workflow is a sequence of actions that can be performed on various targets such as:

• NSP applications: These are the applications that run on NSP such as Network Insight, Service Assurance, Traffic Engineering and others. They can be accessed by using RESTful APIs2.
• Network elements: These are the devices that are managed by NSP such as routers, switches and optical equipment. They can be accessed by using CLI, NETCONF, RESTCONF, SNMP or TL12.
• UNIX servers: These are the servers that run UNIX-based operating systems such as Linux or Solaris. They can be accessed by using SSH or SCP2.

According to the Mistral Workflow Language (v2) documentation1, which is one of the technologies that can be used in a NSP workflow2, with-items is a task property that allows the action associated with a task to be run multiple times over a list of items1. The syntax for using with-items is:

task_name:

action:

input:

:<%item()%>

with-items:itemin

You need to replace , , and  with your desired values. You can also use other properties such as concurrency, retry, or count to control how many iterations are executed in parallel, how many times an iteration is retried if it fails, or how many times an iteration is executed respectively1.
