Which of the following statements about the NSP Kafka service is FALSE?
Correct Answer: D
Explanation The NSP Kafka service is a distributed messaging system that allows different applications to publish and subscribe to different event types. It provides an API client to receive event or alarm notifications and subscribe to different event types. However, it does not use NETCONF based operations and YANG models. Instead, it uses the Kafka protocol to send and receive messages between producers and consumers.
4A0-AI1 Exam Question 37
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.
