NEW QUESTION # 51
Which of the following is NOT an example of good coding principles?
- A. Adding notes/comments into code
- B. Using logging to debug code
- C. Using hard coded values
- D. Offloading code
Answer: C

. WFM supports a variety of use cases such as node software upgrades, service activation tests, service fulfillment and mass migration of services . WFM uses actions and expressions that are extensible using Python1. A workflow action can run against RESTCONF APIs as well as other protocols such as SNMP, NETCONF and CLI1.
NEW QUESTION # 57
Which of the following files contains all the back end implementations required for Intent configurations to be performed?
- A. util.js
- B. script-content.js
- C. meta-info.json
- D. yang-patch.json
Answer: B
Explanation:
Explanation
The script-content.js file contains all the back end implementations required for Intent configurations to be performed.
The script-content.js file is a JavaScript file that defines the logic for creating, updating, deleting and synchronizing intents. It also defines the validation rules and error handling mechanisms for intents.
For example, a script-content.js file could contain:
function createIntent(intent) { // logic for creating an intent }
function updateIntent(intent) { // logic for updating an intent }
NEW QUESTION # 58
Which of the following is the master configuration that is synchronized with the network configuration and is stored in the database as the source of truth?
- A. Intent Type
- B. Intent
- C. Metadata
- D. YANG module
Answer: B
Explanation:
Explanation
An Intent is the master configuration that is synchronized with the network configuration and is stored in the database as the source of truth. Intent Types define the type of Intent, such as a network service or a configuration change, while Metadata is used to store additional information about the Intent, such as its version or author. YANG modules are used to define the data model for a particular technology.

Answer: D
Explanation:
Explanation
According to the NSP Intent Manager Application Help12, if you select "Modify" under "Behavior" in the WebUI and successfully modify an intent, the intent is updated in the Intent Manager database and compared with the configuration on the target node. This will change the intended configuration for the audit and synchronize operations
NEW QUESTION # 61
Which of the following is NOT an advantage of Software-Defined Networks (SDN) over traditional networks?
- A. Network logic is centrally integrated at the controller level
- B. Applications communicate directly with the controller
- C. An integrated control plane and data plane
- D. Greater agility in automating, monitoring, and provisioning network infrastructure
Answer: C
Explanation:
Explanation
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
NEW QUESTION # 62
Which of the following operations CANNOT be performed on an Intent?
- A. Synchronize
- B. Audit
- C. Phase-out
- D. Mark as misaligned
Answer: C
Explanation:
Explanation
some of the operations that can be performed on an Intent are:
* Create
* Synchronize
* Audit
* Update
* Delete
Therefore, based on this source, the answer that CANNOT be performed on an Intent is C. Phase-out.
NEW QUESTION # 63
Which of the following statements about Model-Driven Mediation (MDM) is FALSE?
- A. It is the foundation for supporting multi-vendor device management.
- B. It provides the translation between the AMI and device model.
- C. It can interface with devices that support OpenConfig gRPC Network Management Interface.
- D. It CANNOTcommunicatesthrough devices that only support CLI.
Answer: D
Explanation:
Explanation
Model-Driven Mediation (MDM) is a component that provides mediation between model-driven NSP applications and Nokia or third-party network devices. It uses adaptors to convert NSP application requests to device specific directives using standard protocols such as NETCONF, SNMP and CLI over SSH or Telnet.
This statement is false because MDM can communicate with devices that only support CLI (Command Line Interface) using a translation module that converts CLI commands to NETCONF or RESTCONF protocols.
MDM acts as a mediator between the northbound system and the southbound devices by translating device configuration to a standard format that can be consumed by the northbound system.
The other statements are true:
It is the foundation for supporting multi-vendor device management. C. It provides the translation between the AMI and device model. D. It can interface with devices that support OpenConfig gRPC Network Management Interface.
NEW QUESTION # 64
Which of the following scripting languages can be used to extend WFM actions and expressions?
- A. Groovy
- B. Perl
- C. Python
- D. PHP
Answer: A
Explanation:
Explanation
According to the Nokia NSP Programmable Network Automation website , NSP API documentation and downloadable sample codes are available on the Nokia Network Developer Portal.
