Which of the following is NOT a benefit of virtualization?
Answer : D
some of the benefits of virtualization are:
Reduced capital and operating costs
Better scalability
Higher availability and resiliency
Environmentally friendly
Virtualization enables decoupling of the software and hardware components, so that software can be deployed on any hardware platform without requiring the hardware to be specifically designed for the software. The other three options are all benefits of virtualization.
Software and hardware are tightly coupled is NOT a benefit of virtualization. Virtualization allows software to run independently of the hardware, enabling greater flexibility and scalability. This leads to reduced capital and operating costs, as well as vendor agnostic solutions.
"The automated configuration, coordination, and management of large virtualized systems, middleware, and services" describes which of the following?
Answer : B
orchestrationis the automated configuration, coordination, and management of computer systems and software. Orchestration takes advantage of several tasks that are usually automated to create a more complex workflow.
An orchestrator is a software tool that is used to automate the configuration, coordination, and management of large virtualized systems, middleware, and services. The other three options are not related to the automated configuration, coordination, and management of large virtualized systems, middleware, and services.
Orchestrator is described as 'the automated configuration, coordination, and management of large virtualized systems, middleware, and services.' The orchestrator is a key component of network automation, enabling the automation and management of complex network functions across multiple devices and platforms.
Which Workflow state allows a Workflow to be executed?
Answer : C
According to the Workflow Manager User Guide from Nokia, the correct answer is C. Published. When a workflow is in the Published state, it can be executed by users who have the appropriate permissions. The Draft state is used during the creation of a new workflow, while the Deprecated state indicates that a workflow is no longer supported and should not be used. The Released state is not mentioned in the context of workflow execution.
Which of the following statements about Nokia's Network Services Platform (NSP) Model-driven Mediation (MDM) framework is FALSE?
Answer : D
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 asNETCONF, SNMP and CLI over SSH or Telnet12.MDM also provides an abstracted view of the network element3.
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
Answer : C
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 best describes data flow in a workflow?
Answer : B
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 topassing data between tasks12. Therefore, the correct answer is B.
Data flow can be defined usinginput,output, andpublishparameters 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 is NOT a benefit of ZTP?
Answer : B
The option that is NOT a benefit of ZTP (Zero Touch Provisioning) is:
1. 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:
2. 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 source2mentions 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 source3explains that ZTP uses Cisco Plug and Play (Cisco PnP) to verify devices and perform downloads over a secure, encrypted channel.
