Snowflake SnowPro Advanced: Data Analyst Certification Exam DAA-C01 Prüfungsfragen mit Lösungen (Q42-Q47):

42. Frage
You are working on a data ingestion pipeline that loads data from a CSV file into a Snowflake table called The CSV file occasionally contains invalid characters in the 'Email' column (e.g., spaces, non-ASCII characters). You want to ensure data integrity and prevent the entire load from failing due to these errors. Which of the following strategies, used in conjunction, would BEST handle this situation during the COPY INTO command and maintain data quality?

A. Use the 'ON ERROR = 'CONTINUE" option in the 'COPY INTO' command. Create a separate error queue table and configure the 'COPY INTO' command to automatically insert error records into the queue.
B. Use a file format with 'VALIDATE UTF8 = TRUE, and 'ON ERROR='SKIP FILE". Create a separate stage containing invalid data to be handled at a later stage with another transformation job
C. Use the ERROR = 'SKIP FILE" option in the 'COPY INTO' command along with a file format that specifies 'TRIM SPACE = TRUE and 'ENCODING ='UTF8".
D. Use the 'ON ERROR = 'SKIP FILE" option in the 'COPY INTO' command and then run a subsequent SQL query to identify and correct any invalid email addresses in the 'EmployeeData' table.
E. Employ the 'VALIDATE function during the 'COPY INTO command to identify erroneous Email columns and use the 'ON ERROR = 'CONTINUE" along with using file format that specifies 'TRIM_SPACE = TRUE and ENCODING = 'UTF8".

Antwort: A,E

Begründung:
Options B and E provide the most robust solution. ERROR = 'CONTINUE'' allows the load to proceed despite errors. Creating an error queue (implicitly handled by Snowflake if using allows you to examine and address the problematic records later. By including in the file format definition = TRUE' and 'ENCODING = 'UTF8" and 'VALIDATE' function during the 'COPY INTO command to identify erroneous Email columns, you can standardize character encoding. 'SKIP_FILE (options A, C, and D) might lose valuable data. While correcting data with SQL after the load (option C) is possible, capturing the error data directly during the load is more efficient.

43. Frage
What role does operationalizing data play in maintaining reports and dashboards for business requirements?

A. It restricts data updates, affecting dashboard accuracy.
B. Operationalizing data complicates dashboard management.
C. It limits the usability of reports by narrowing down access.
D. Operationalizing data ensures consistent and efficient usage.

Antwort: D

Begründung:
Operationalizing data ensures consistent and efficient usage of reports and dashboards.

44. Frage
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 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.
B. 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.
C. 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.
D. Using a HAVING clause after grouping by sensor_id to filter out groups where the range of reading_value exceeds a certain threshold.
E. Using window functions to calculate the mean and standard deviation for each sensor, then filtering the results to exclude outliers using a WHERE clause.

Antwort: A,C,E

Begründung:
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.

45. Frage
What actions can be taken when responding to processing failures in data processing solutions?
(Select all that apply)

A. Identify the root cause of failure
B. Resume processing from the point of failure
C. Log error details for analysis
D. Restart the entire data processing flow

Antwort: A,B,C

Begründung:
Responding to processing failures involves logging error details, identifying the root cause, and resuming processing from the failure point.

46. Frage
A data analyst accidentally dropped a crucial table, 'SALES DATA', containing historical sales information. The table was dropped 5 days ago. The data retention period for the Snowflake account is set to the default value. The analyst needs to recover the table with all its data'. What is the MOST efficient and reliable method to recover the 'SALES DATA" table in Snowflake?

A. Request Snowflake Support to restore the table from their backups.
B. Restore the table using the 'UNDROP TABLE SALES DATA' command.
C. Use the 'TIME TRAVEL' function in a SELECT statement to retrieve the data and recreate the table.
D. create a clone of the table using Time Travel at a point in time before it was dropped, using the 'CREATE TABLE CLONE SALES DATA BEFORE(STATEMENT y command.
E. create a clone of the table using Time Travel at a point in time before it was dropped, using the 'CREATE TABLE CLONE SALES DATAAT (OFFSET -86400 5)' command.

Antwort: B

Begründung:
The 'UNDROP TABLE command is the most efficient and direct method to recover a dropped table, as long as it's within the data retention period. Since the table was dropped 5 days ago and the default retention period is typically sufficient (can be up to 90 days in Enterprise Edition), 'UNDROP TABLE should work. While options B and E are valid uses of cloning and time travel, they involve creating a new table and are less direct. Requesting Snowflake support (C) is unnecessary for a simple table recovery. Option D will require data extraction and recreating the table structure, which is tedious and time-consuming compared to 'UNDROP'
