Exam DAA-C01 Topic 1 Question 66 Discussion

Actual exam question for Snowflake's DAA-C01 exam
Question #: 66
Topic #: 1
You are tasked with creating a dashboard to visualize website traffic data'. The data is stored in a Snowflake table 'WEB EVENTS' with the following columns: 'EVENT_ID', 'USER_ID', 'EVENT_TIMESTAMP', 'PAGE_URL', 'SESSION_ID', and 'DEVICE_TYPE. You need to calculate the average session duration for each device type, but the 'WEB EVENTS' table only contains individual events, not session start and end times. Assume a session is defined by a unique 'SESSION ID' for each 'USER ID. You are given a window function to calculate the start time and end time for a given 'SESSION ID': First_value and last_value. What steps are crucial to calculate average session duration by 'DEVICE TYPE?

Suggested Answer: B Vote an answer

Option B correctly identifies the steps to calculate session duration. First determine Session Start and End time. 1) Use window functions to identify the start and end timestamp for a given SESSION ID. 2) Calculate the difference between these timestamps. 3) Group by device type to arrive at the averages for session duration across the device_type. Option A is incorrect as it does not represent the session duration which needs to be calculated for a given Session_ID.
