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, 131

How many times the notification would be sent to the team if Just once is selected in the When triggered, send notification field?

1. 3 times

2. 1 time

3. 5 times

4. No notification will be sent

5. 6 times

Correct 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 state

109 -> Remains in the TRIGGERED state

98 -> Changed to OK (Notification is sent for the second time)

67 -> Remains in the OK state

101 -> Changed to TRIGGERED (Notification is sent for the third time)

121 -> Remains in the TRIGGERED state

98 -> Changed to OK (Notification is sent for the fourth time)

79 -> Remains in the OK state

131 -> 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.
