UPDATE - DO CHECK THE ANNOUNCEMENT SECTION. DATABRICKS NOTEBOOKS ADDED IN EACH CODE-BASED QUESTION. Passing an exam is not an easy task and acing it is even more difficult and that is why we, at Certification Champs, offer Practice exams that are right from the top drawer of the top shelf.These carefully handcrafted 180 questions distributed in 3 practice tests in accordance with the Databricks exam syllabus give you an integrated feel of the actual exam. Each question is made to test one of the topics of the actual exam and gives you a detailed explanation for every question. These practice exams enable you to clear the certification on your first attempt.The explanation part of the questions not only gives you an in-depth explanation but also explains the concept behind the question in detail. Also, each code-based question has a Databricks Notebook attached to it. You can easily import the Notebook into your Databricks account to play around the code.Let's get you started with a sample question from the practice exam.Question: A query is created for sending notifications to the team when the number of pending orders is more than 100 for a manufacturing startup. The query is set to refresh every hour. For the past 10 hours, the pending_orders column returned the following values:120, 115, 109, 98, 67, 101, 121, 98, 79, 131How many times the notification would be sent to the team if Just once is selected in the When triggered, send notification field?3 times1 time5 timesNo notification will be sent6 timesCorrect Option: Option 3 (5 times)Explanation: In the above question, Just once is selected in the When triggered, send notification field. Let us look at the status after every hour:120 -> Changed to TRIGGERED (Notification is sent for the first time)115 -> Remains in the TRIGGERED state109 -> Remains in the TRIGGERED state98 -> Changed to OK (Notification is sent for the second time)67 -> Remains in the OK state101 -> Changed to TRIGGERED (Notification is sent for the third time)121 -> Remains in the TRIGGERED state98 -> Changed to OK (Notification is sent for the fourth time)79 -> Remains in the OK state131 -> Changed to TRIGGERED (Notification is sent for the fifth time)This analysis makes it clear that while using Just Once, the notification is sent to the team whenever the status is changed from OK to TRIGGERED or TRIGGERED to OK. Moreover, if the status remains in the TRIGGERED or OK state for more than one hour, the notification will be sent only for the first hour. For instance, in the first 3 hours, the status remains TRIGGERED but the notification is sent only for the first hour. Similarly, the status remains OK for the next 2 hours but the notification will be sent for the first time the state is changed i.e. in the fourth hour.CERTIFICATION SYLLABUSThe certification syllabus is distributed in five sections:Databricks Tooling - 12 questions i.e. 20%Data Processing - 18 questions i.e. 30%Data Modeling - 12 questions i.e. 20%Security and Governance - 6 questions i.e. 10%Monitoring and Logging - 6 questions i.e. 10%Testing and Deployment - 6 questions i.e. 10%IMPORTANT NOTEAlthough the passing percentage is just 70% you should consider getting at least 85% in each practice exam before going for the actual exam.DISCLAIMERThese questions are designed by our team to give you a feel of the level of questions asked in the actual exam.
