"The automated configuration, coordination, and management of large virtualized systems, middleware, and services" describes which of the following?
Correct Answer: B
Explanation orchestration is 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.
Question 17
Which of the following is NOT a valid flow control attribute?
Correct Answer: A
Explanation According to the Mistral Workflow Language (v2) documentation1, which is one of the technologies that can be used in a NSP workflow2, flow control attributes are used to define how a task behaves depending on its execution status. The valid flow control attributes are on-success, on-error, on-complete, and on-cancel1. Therefore, the correct answer is A.
Question 18
Which of the following is NOT a building block of NSP automation?
Correct Answer: A
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
Question 19
Which of the following is NOT an advantage of Software-Defined Networks (SDN) over traditional networks?
Correct Answer: C
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
Question 20
Which of the following statements about NSP APIs is FALSE?
Correct Answer: B
Explanation NSP APIs allow for supervision of network elements, help with the definition and activation of network services, and allow for an OSS and NSP server to talk to each other. However, they do not support GraphQL, which is a query language for APIs. According to Nokia NSP IP Network Automation Professional guide, NSP APIs support REST/RESTCONF, SOAP/XML and GraphQlll, and help with the definition and activation of network services, and they also allow for supervision of network elements and an OSS and NSP server to talk to each other. Therefore, statement B is false as it states that NSP APIs support Kafka which is not mentioned in the guide as a supported API.
