Databricks Machine Learning Professional Question 116
Single answerYou are designing a machine learning pipeline in Databricks to automate predictions for incoming data. You want to notify an external monitoring system in real-time whenever a model inference job completes successfully. Which of the following describes a valid use case for HTTP webhooks, and where should the Webhook URL be obtained?
- A
Use HTTP webhooks to trigger the external monitoring system, and the Webhook URL should be provided by the external system.
- B
Use HTTP webhooks to trigger the external monitoring system, and the Webhook URL should be generated by Databricks.
- C
Use HTTP webhooks to notify Databricks whenever the external system completes its task, and the Webhook URL should be provided by Databricks.
- D
Use HTTP webhooks to send data directly to a database, and the Webhook URL should be provided by the database.
Show answer and explanation
Correct answer: A
Explanation
HTTP webhooks are used to send real-time notifications from one system to another. In the context of Databricks, they are useful for notifying external systems (such as monitoring tools) about events like the completion of a machine learning inference job. The Webhook URL is always provided by the external system that will receive the notification since it represents the endpoint where the notification is sent.
- A. Correct.
Correct: HTTP webhooks are commonly used to send real-time notifications to external systems. In this case, the Webhook URL must be provided by the external monitoring system as it is the endpoint that listens for incoming requests.
- B. Incorrect.
Incorrect: Databricks does not generate Webhook URLs. The Webhook URL is typically supplied by the external system that will process the notification.
- C. Incorrect.
Incorrect: This reverses the roles of Databricks and the external system. In this scenario, Databricks is the sender of the notification, not the receiver.
- D. Incorrect.
Incorrect: HTTP webhooks are not designed to send data directly to a database. Instead, webhooks are used to notify systems with an HTTP endpoint, such as monitoring systems or APIs.
