Explanation The option that is NOT a benefit of ZTP (Zero Touch Provisioning) is: 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: 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.
Question 12
Which of the following protocols or standards is NOT used in Model Driven Telemetry?
Correct Answer: A
Explanation CLI is not used in Model Driven Telemetry. Model Driven Telemetry is a technology that uses YANG data models, NETCONF, gRPC and KAFKA to monitor and collect data from network elements. It provides an abstracted view of the network element and is vendor agnostic. Model Driven Telemetry is a method of collecting real-time data from network devices, allowing for more efficient network monitoring and troubleshooting. It uses a variety of protocols and standards, including NETCONF, gRPC, and Kafka. However, CLI is a text-based user interface used for issuing commands to a device, and it is not typically used for collecting telemetry data. According to the Nokia Network Services Platform for industry and the public sector datasheet1, NSP model-driven telemetry framework supports the Nokia SR OS and third-party devices in configuring and collecting performance statistics using gRPC, SNMP, NETCONF and accounting files such as SAP QoS1. It also enables data to be persisted in a database and be made available (e.g., over a Kafka bus) for a variety of use cases1.
Question 13
Which of the following is NOT an example of good coding principles?
Correct Answer: C
Explanation Good coding principles aim to make the code more maintainable and easier to debug. Offloading code and using logging to debug code are both good coding principles, as they make the code more efficient and easier to debug. Adding notes and comments into code is also a good coding practice, as it makes the code more readable and understandable. However, using hard coded values is not a good coding practice, as it makes the code more difficult to maintain and debug.
Question 14
Which of the following system actions will pause a workflow at some point and wait for an operator to confirm or deny a particular course of action?
Correct Answer: C
Explanation This system action allows you to pause a workflow and prompt the user for input. You can use this action to confirm or deny a course of action, or to enter some data that isrequired for the workflow1. For example, you can use nsp.user_input to ask the user if they want to continue with a service deployment or rollback. The other options are not correct because: * std.sleep is a standard Python function that pauses the execution of a script for a specified number of seconds2. * nsp.wait is a system action that waits for an event or condition to occur before resuming the workflow1. For example, you can use nsp.wait to wait for a service activation status change or a network element alarm. * nsp.pause_before is not a valid system action. There is no such action defined in the NSP documentation 1.
Question 15
Which of the following HTTP methods are NOT supported in REST and RESTCONF?
Correct Answer: 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.
