NEW QUESTION # 21
Which of the following best describes data flow in a workflow?
- A. Transitioning between tasks
B, Passing data between tasks - B. Defines operation to perform
- C. Dependency graph of tasks
Answer: C
Explanation:
Explanation
According to the Nokia NSP Workflow Design and Management course12, a workflow is a sequence of tasks that are executed to achieve a certain goal. Data flow in a workflow refers to passing data between tasks12.
Therefore, the correct answer is B.
Data flow can be defined using input, output, and publish parameters in a workflow definition3. Input parameters are used to pass data into a workflow, output parameters are used to return data from a workflow, and publish parameters are used to share data between tasks within a workflow3.

Which of the following Kafka components represents a stream of messages of a particular category?
- A. Topic
- B. Producer
- C. Broker
- D. Consumer
Answer: A
Explanation:

NEW QUESTION # 24
Which of the following is NOT a building block of NSP automation?
- A. Multi-vendor support
- B. Model-driven mediation
- C. Analytics & telemetry
- D. Terminal emulation configuration
Answer: D
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
