- A. It is based on the YANG data model.
- B. It is vendor agnostic.
- C. It uses the NETCONF protocol.
- D. It provides an abstracted view of the network element.
Answer: B
Explanation:
Explanation
The Nokia NSP Model-driven Mediation (MDM) framework is based on the YANG data model, uses the NETCONF protocol, and provides an abstracted view of the network element. However, it is designed to be vendor-specific, meaning it is designed to only manage Nokia equipment.
It provides an abstracted view of the network element is FALSE regarding Nokia's Network Services Platform (NSP) Model-driven Mediation (MDM) framework. MDM provides a way to interface between the Nokia NSP and network elements from different vendors. It is based on the YANG data model and uses the NETCONF protocol to provide configuration and management capabilities for network devices. However, MDM does not provide an abstracted view of the network element. Instead, it translates the native configuration of the network element into a standardized YANG model, allowing the NSP to manage the network element in a vendor-agnostic way.
According to the NSP NSD and NRC 18.6 Planning Guide1, Model-Driven Mediation (MDM) is a component within the NSP architecture that provides mediation between model-driven NSP applications and Nokia or third-party network devices. MDM provides an adaptation layer which uses adaptors to convert NSP application requests to device specific directives using standard protocols such as NETCONF, SNMP and CLI over SSH or Telnet12. MDM also provides an abstracted view of the network element3.

Which of the following is NOT a benefit of Intent Manager?
- A. Provides concepts for finding misalignments.
- B. Allows programmable and flexible logic.
- C. Provides flexible capabilities for achieving high-level bus
- D. Allows the parallel execution of many workflows.
Answer: D
Explanation:
Explanation
According to the Nokia NSP Intent Manager Application Help2, Intent Manager has the following benefits:
* It allows programmable and flexible logic. You can use scripts to define how intents are translated into network commands and how they react to network events.
* It provides concepts for finding misalignments. You can use audit and synchronize functions to detect and resolve any discrepancies between intents and network states.
* It provides flexible capabilities for achieving high-level business goals. You can use intents to express complex network behaviors such as service protection, bandwidth optimization, or latency reduction.
Therefore, based on these sources
Allows the parallel execution of many workflows.
This is NOT a benefit of Intent Manager because workflows are not related to intents. Workflows are sequences of tasks that can be executed on NSP using Workflow Manager.
NEW QUESTION # 50
Which of the following commands allows the action associated with a task to be run multiple times over a list of items?
- A. concurrency
- B. retry
- C. with-items
- D. count
Answer: C
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>
