Which of the following is NOT a building block of NSP automation?
- A. Multi-vendor support
- B. Terminal emulation configuration
- C. Model-driven mediation
- D. Analytics & telemetry
Answer: B
Explanation:
Explanation
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 Engineering
* 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 equipment
* 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 management

NEW QUESTION # 24
Which of the following statements best describes the Intent Manager application?
- A. It generates and validates the configuration of the network.
- B. It manages YANG-based telemetry.
- C. It discovers and manages network elements so they can be used by other NSP applications.
- D. It provides the ability to simulate changes in the IP topology.
Answer: A
Explanation:
Explanation
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.
NEW QUESTION # 25
Which of the following commands allows the action associated with a task to be run multiple times over a list of items?
- A. count
- B. with-items
- C. retry
- D. concurrency
Answer: B
Explanation:
Explanation
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:<action_name>
input:
<input_name>:<%item()%>
with-items:itemin<list>
You need to replace <action_name>, <input_name>, and <list> 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.
