Which of the following is NOT part of the Augmented Assurance features provided by the NSP?
C
Explanation:
Augmented Assurance is a feature that provides “extended automated network operations” with
“open APIs and no-code customizable workflows”. Another source2 mentions that NSP offers
“automated repetitive tasks and complex workflows” to reduce operating costs.
The Augmented Assurance features provided by the NSP (Nokia Network Services Platform) include:
A. Sorting NEs by highest severity issues B. Intelligent visualization D. On-demand OAM testing
Which of the following statements about Model-Driven Mediation (MDM) is FALSE?
A
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:
B. 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.

Which of the following statements about REST and RESTCONF is FALSE?
D
Explanation:
REST and RESTCONF APIs provide a single entry point into the consolidated suite of NSP
applications. Another source2 mentions that NSP REST gateway provides access to NSD and NRC
functionalities through REST API services. A third source3 explains that RESTCONF is an HTTP-based
protocol that performs CRUD operations on data using YANG models.
Which of the following is NOT a benefit of ZTP?
B
Explanation:
The option that is NOT a benefit of ZTP (Zero Touch Provisioning) is:
B. Increases network throughput.
ZTP is a network device deployment method that automates the initial configuration process of
network devices, eliminating the need for manual intervention. The benefits of ZTP include:
A. Lowers overall time for network rollout C. Optimizes costs D. Minimizes the amount of commands
typed
ZTP is a method of setting up devices that automatically configures the device using a switch
feature. Another source2 mentions that ZTP helps IT teams quickly deploy network devices in a
large-scale environment, eliminating most of the manual labor involved with adding them to a
network. A third source3 explains that ZTP uses Cisco Plug and Play (Cisco PnP) to verify devices and
perform downloads over a secure, encrypted channel.
Which of the following HTTP methods is NOT supported by REST/RESTCONF?
E
Explanation:
The HTTP methods that are supported by REST/RESTCONF are:
OPTIONS: Used to retrieve the communication options available for a resource.
GET: Used to retrieve a representation of a resource.
PATCH: Used to apply a partial update to a resource.
POST: Used to create a new resource or trigger a specific action.
The HTTP method TRACE is not supported by REST/RESTCONF.
Reference: Nokia NSP IP Network Automation Professional Guide, page 77.
Which of the following HTTP methods are NOT supported in REST and RESTCONF?
D
Explanation:
The HTTP methods that are supported by REST/RESTCONF are:
GET: Used to retrieve a representation of a resource.
PUT: Used to replace a resource or create it if it does not exist.
DELETE: Used to delete a resource.
PATCH: Used to apply a partial update to a resource.
The HTTP method ADD is not a standard HTTP method and is not supported by REST/RESTCONF.
Reference: Nokia NSP IP Network Automation Professional Guide, page 77.
What are the two main functionalities of the NSP REST API gateway services?
1. Versioning model
2. Create subscriptions
3. Location services
4. Authentication and termination services
C
Explanation:
the NSP REST Gateway API provides the entry point for API clients to locate and authenticate REST
client requests to gain access to the various NSP modules that have registered API services.
Which of the following statements about the YANG data modeling language is FALSE?
C
Explanation:
YANG is a data modeling language used to model configuration and state data for network devices. It
defines a tree-like structure for data and is used to store, configure, and retrieve information from
network devices. It is human readable and can be used to define actions and operations.
Which of the following Kafka components represents a stream of messages of a particular category?
C
Explanation:
a Kafka topic is a channel where publishers (producers) publish data and where subscribers
(consumers) receive data. A topic represents a stream of messages of a particular category.
In Kafka, a topic represents a stream of messages of a particular category or type. Producers publish
messages to a specific topic, and consumers subscribe to and read messages from topics. Brokers are
responsible for managing topics and ensuring that messages are distributed efficiently across the
cluster.
Which of the following statements about Kafka is FALSE?
D
Explanation:
Kafka is a distributed messaging system that is open-source and can be used to send real-time
notifications. However, it has more than four components, such as brokers, partitions, replicas,
consumer groups and zookeeper.
