Databricks Certified Data Engineer Professional — Question 122

What is the first line of a Databricks Python notebook when viewed in a text editor?

Answer options

• A. %python
• B. // Databricks notebook source
• C. # Databricks notebook source
• D. -- Databricks notebook source

Correct answer: C

Explanation

The correct answer is C, as the first line of a Databricks Python notebook is marked with a '#' to indicate a comment. Options A and B are incorrect because they do not represent the correct syntax for a Databricks notebook, and D is also incorrect since '--' is not used for comments in this context.
