질문 # 41
When building a Snowsight dashboard that will allow users to filter data within a worksheet, which Snowflake system filters should be used?

A. Include the :daterange system filter in a WHERE clause, and include the :datebucket system filter in a GROUP BY clause.
B. Include the :datebucket system filter in a WHERE clause, and include the :daterange system filter in a SELECT clause.
C. Include the :datebucket system filter in a WHERE clause, and include the :daterange system filter in a GROUP BY clause.
D. Include the :daterange system filter in a SELECT clause, and include the :datebucket system filter in a GROUP BY clause.

정답：A

설명：
Snowsight provides special System Keywords that allow analysts to create dynamic, interactive dashboards without hard-coding dates. Two of the most critical keywords are :daterange and :datebucket.
The :daterange keyword is designed to filter the volume of data based on a time period selected by the user in the dashboard UI (e.g., "Last 30 days" or "Current Year"). Because it acts as a filter on the underlying data, it must be placed in the WHERE clause of the SQL statement (e.g., WHERE created_at = :daterange). This ensures that only the records within the selected timeframe are processed by the query.
The :datebucket keyword is used for time-series aggregation. It allows the user to dynamically change the granularity of the data-for example, switching a chart from "Daily" to "Monthly" views without rewriting the query. To achieve this, :datebucket is used inside a date-truncation function in the SELECT list and, crucially, must be included in the GROUP BY clause to correctly aggregate the metrics (e.g., GROUP BY 1 or GROUP BY :datebucket).
Evaluating the Options:
* Option A is incorrect because :datebucket is for grouping/truncation, not for filtering in a WHERE clause.
* Option B is incorrect because :daterange is a filter (returning a range), not a scalar value suitable for a SELECT list.
* Option C is incorrect for the same reasons as A and B.
* Option D is the 100% correct answer. It follows the standard Snowsight design pattern: :daterange restricts the data rows in the WHERE clause, while :datebucket defines the temporal aggregation level in the GROUP BY clause.

질문 # 42
A company stores sensor data, including timestamps (ts), sensor ID (sensor_id), and readings (reading_value), in a Snowflake table named 'sensor_data'. Due to sensor malfunctions, some readings are significantly higher or lower than expected (outliers). Which of the following approaches are suitable in Snowflake to calculate the average reading value for each sensor, EXCLUDING readings that fall outside of two standard deviations from the mean for that sensor?

A. Using window functions to calculate the mean and standard deviation for each sensor, then filtering the results to exclude outliers using a WHERE clause.
B. Using a HAVING clause after grouping by sensor_id to filter out groups where the range of reading_value exceeds a certain threshold.
C. Using a LATERAL FLATTEN function to transform reading values into an array, calculate the mean and standard deviation in a JavaScript UDF, then use ARRAY SLICE to remove outliers before calculating the average.
D. Using a QUALIFY clause with window functions to filter out the outlier readings based on their distance from the mean, prior to calculating the final average.
E. Calculating the mean and standard deviation for each sensor in a subquery, then joining the results with the original data and filtering based on the calculated values.

정답：A,D,E

설명：
Options A, B and C provides valid ways to determine outliers. A is based on direct filtering based on standard deviation on the original table using window function. B uses Sub query approach and filtering. C allows to use QUALIFY clause with window functions for filtering before aggregation. D attempts to filter groups based on range which is not the intent of the original question to filter on a per reading basis if its an outlier or not. Option E, although technically possible, introduces significant complexity and performance overhead with the use of UDF and array manipulation for a task achievable with standard SQL.

질문 # 43
How can automated and repeatable tasks contribute to maintaining reports and dashboards in meeting business requirements?

A. Automated tasks ensure consistency and reduce manual effort.
B. They solely increase the complexity of dashboard management.
C. Repeatable tasks hinder data updates in dashboards.
D. They limit the scalability of dashboards and reports.

정답：A

설명：
Automated tasks ensure consistency and reduce manual effort in maintaining reports and dashboards.

질문 # 44
You are analyzing customer order data in Snowflake. A column 'ORDER DATE' is stored as VARCHAR. You notice inconsistencies: some dates are in 'YYYY-MM-DD' format, others in 'MM/DD/YYYY', and some have missing values represented by 'N/A'. You need to standardize the 'ORDER DATE' column into a DATE format and handle missing values. What is the most efficient and robust Snowflake SQL statement to achieve this, ensuring no data is lost and that invalid dates are replaced with NULL?

A. Option C
B. Option E
C. Option B
D. Option A
E. Option D

정답：B

설명：
Option B is the most robust and efficient because it uses REGEXP LIKE to validate the date formats before attempting to convert them using TRY_TO_DATE. It also directly creates a temporary table to perform the transformation, minimizing the risk of data loss during the process. Then the old table is replaced with the content of the temp table.

질문 # 45
How does understanding and analyzing the Query Profile contribute to query optimization in Snowflake?

A. Limits query access for specific user roles
B. Facilitates query planning and execution analysis
C. Provides real-time data updates
D. Validates query result consistency

정답：B

설명：
Analyzing the Query Profile aids in understanding query planning and execution, offering insights into optimizing query performance in Snowflake by identifying execution steps and bottlenecks.
