Snowflake SnowPro Advanced: Data Analyst Certification Exam Sample Questions (Q29-Q34):

NEW QUESTION # 29
You are tasked with validating the 'SALES DATA' table containing sales records. One of the columns, 'SALE AMOUNT', is defined as VARCHAR, but it should be a NUMERIC. Some rows contain non-numeric characters and NULL values represented as the string 'NULL'. You need to identify rows that will cause errors when casting 'SALE AMOUNT to NUMERIC, and replace these rows with valid values using Snowflake SQL. Which of the following SQL statements, when executed in sequence, effectively identifies and corrects problematic 'SALE AMOUNT' values? Note: Assume the "REPLACE INVALID CHARACTERS' UDF correctly replaces non- numeric characters with empty strings.

Answer: B

Explanation:
Option D correctly addresses all aspects of the problem. First, it replaces 'NULL' string values with actual NULLs. Then, it creates a temporary table, 'INVALID SALES, containing rows where 'SALE AMOUNT, after removing invalid characters, cannot be converted to a DECIMAL. Finally, it updates these invalid rows in the original table with a default value of '0'. TRY_TO_DECIMAL is important for handling decimal values that cannot be converted

NEW QUESTION # 30
Which statement accurately describes the use of regular views in data analysis?

A. Regular views are exclusively used for administrative tasks.
B. Regular views offer real-time updates to reflect instantaneous database changes.
C. Regular views limit data accessibility for improved security.
D. They simplify complex data structures, aiding ease of analysis.

Answer: D

Explanation:
Regular views aid analysis by simplifying complex data structures, improving comprehension.

NEW QUESTION # 31
Which Snowflake feature or object can be used to dynamically create and execute SQL statements?

A. System-defined functions
B. Stored procedures
C. Tasks
D. User-Defined Functions (UDFs)

Answer: B

Explanation:
While Snowflake provides various ways to encapsulate logic, Stored Procedures are the primary tool for procedural programming and dynamic SQL execution. Unlike standard UDFs, which are generally designed to calculate and return values within a query, stored procedures can execute administrative commands (DDL) and data manipulation (DML) that are not possible in a simple SELECT statement.
Using Snowflake Scripting (or languages like Python, Java, or JavaScript), an analyst can write a procedure that builds a SQL string as a variable and then executes it using the EXECUTE IMMEDIATE command. This is demonstrated in procedural logic flows where inputs determine specific execution paths. While Tasks can be used to schedule the execution of these procedures, the task itself is a scheduling agent and does not provide the logic-driven dynamic string construction inherent to the procedure.

NEW QUESTION # 32
You need to create a dashboard for a logistics company to track delivery performance. The dashboard should display the following information: (1) Total number of deliveries per day, (2) Percentage of deliveries completed on time, (3) Average delivery time per city, (4) Number of deliveries exceeding the SLA (Service Level Agreement) by more than 1 hour. Which of the following chart combinations would be MOST effective to display this information in a clear and concise manner?

A. Area chart for total deliveries per day, scorecard for percentage of on-time deliveries, geographical map with color-coded cities for average delivery time, and a bar chart for deliveries exceeding SLA.
B. Bar chart for total deliveries per day, scorecard for percentage of on-time deliveries, geographical map with color-coded cities for average delivery time, and a table showing deliveries exceeding SLA.
C. Line chart for total deliveries per day, pie chart for percentage of on-time deliveries, bar chart for average delivery time per city, and a table showing deliveries exceeding SLA
D. Time series chart for total deliveries per day, gauge chart for percentage of on-time deliveries, a heat grid showing city vs average delivery time, and a bullet chart for deliveries exceeding SLA target.
E. Time series chart for total deliveries per day, scorecard for percentage of on-time deliveries, geographical map with color-coded cities for average delivery time, and a table showing deliveries exceeding SLA.

Answer: E

Explanation:
A Time series chart is best for showing trends over time (total deliveries per day). A scorecard provides a concise view of a key metric (percentage of on-time deliveries). A geographical map with color-coded cities effectively visualizes location-based data (average delivery time per city). A table provides detailed information on specific instances (deliveries exceeding SLA). Pie Charts are less ideal for percentage since it can be achieved better using Scorecard, heat grid not the best choice when geo is involved and it is less readable.

NEW QUESTION # 33
You are loading data from a series of CSV files into Snowflake using Snowsight. The files have varying column orders and some files are missing certain columns. You need to ensure that all data is loaded into a consistent table schema, handling missing columns gracefully.
Which of the following strategies is MOST effective in Snowsight to achieve this?

A. Pre-process the CSV files before loading using a scripting language (e.g., Python) to standardize the column order and add missing columns with NULL values. Then, load the pre-processed files into Snowflake using Snowsight.
B. Create multiple file formats, one for each unique CSV file structure. Use Snowsight's 'Load Data' wizard to load each set of files with the corresponding file format. Use UNION ALL to combine the data from multiple tables into a single view.
C. Define a file format with 'SKIP HEADER = 1', "FIELD OPTIONALLY ENCLOSED BY = and "NULL _ IF = (", 'NULL')'. Create a single table with all columns defined and use Snowsight's 'Load Data' wizard to load the CSV files. Columns not present in a given CSV file will automatically be populated with NULL.
D. Load the data into a staging table with a single VARIANT column. Then, use SQL with 'CASE statements and 'GET ' function to extract data from the VARIANT column into the target table with the desired schema.
E. Define a file format with 'SKIP_HEADER = 1 ' and load all CSV files into a single table with all possible columns defined as VARCHAR. After loading, use SQL queries with and to convert the data to the appropriate data types.

Answer: C

Explanation:
Option D is the most effective strategy. By defining the file format with 'SKIP_HEADER = , FIELD_OPTIONALLY_ENCLOSED_BY ' and 'NULL_IF = (", 'NULL')', Snowflake can handle missing columns by populating them with NULL values during the load process. Creating a single table with all columns defined ensures data consistency. Option A works, but the type conversion after loading is less efficient and more error-prone. Option B requires managing multiple file formats and using UNION ALL, which can be complex. Option C using VARIANT will work, but adds extra complexity. Option E requires an external preprocessing step, which is less desirable.
