Snowflake SnowPro Advanced: Data Analyst Certification Exam Sample Questions (Q19-Q24):

NEW QUESTION # 19
A financial institution is migrating its transactional data warehouse to Snowflake. They need to optimize query performance for daily reporting on customer spending habits. The current data model is a highly normalized relational model with numerous joins across multiple tables. The reporting requirements include frequent aggregations and filtering on customer demographics, transaction types, and date ranges. Which data modeling approach would be MOST effective in this scenario, considering Snowflake's architecture and the need for performant reporting?

A. Create a snowflake schema with several layers of normalized dimensions to reduce storage costs.
B. Maintain the existing highly normalized model and rely solely on Snowflake's query optimizer to handle the joins.
C. Implement a star schema with a central fact table for transactions and dimension tables for customer demographics, transaction types, and dates.
D. Denormalize the data into a single, wide fact table containing all necessary attributes to avoid joins during reporting.
E. Use a third normal form (3NF) data model to minimize data redundancy and ensure data integrity.

Answer: C

Explanation:
A star schema is generally the most effective for Bl reporting in Snowflake. It simplifies query complexity by reducing the number of joins, which improves query performance. Snowflake handles wide tables well, but a single, wide fact table (option B) might become unwieldy. Maintaining the existing normalized model (option A) will likely lead to poor performance. 3NF(Option D) is suitable for OLTP, not OLAP. Snowflake schemas (Option E), while saving storage costs, introduce more joins and can negatively impact performance compared to the Star schema.

NEW QUESTION # 20
You are developing a data pipeline that involves loading data from multiple CSV files stored in an Amazon S3 bucket into a Snowflake table. The files have different schemas (different column names and data types), but all files contain a common column named 'record_type' that identifies the schema of the data in that file. You need to create a single Snowflake table that can store data from all the files, while ensuring data integrity and proper data typing based on the 'record_type'. Which of the following approaches is the MOST efficient and scalable method to achieve this in Snowflake?

A. Create multiple Snowflake tables, one for each 'record_type', with the corresponding schema. Use a Snowflake task that runs periodically to identify new files in the S3 bucket, determine their 'record_type', and load them into the appropriate table using a dynamic SQL query.
B. Create a single, wide Snowflake table with all possible columns from all CSV files, defining all columns as VARCHAR. Load all data into this table, then create views for each 'record_type' that cast the data to the correct data types.
C. Create a single external table pointing to the S3 bucket. Use a Snowflake stream on the external table to track changes. Implement a series of tasks, one for each 'record_type', that transform data from the stream and load into a single target table with appropriate datatypes.
D. Create a single Snowflake table with a VARIANT column to store the raw data. Use a Snowpipe to load the data continuously. Implement a stored procedure that is triggered by the Snowpipe to parse the VARIANT data based on 'record_type' and insert it into correctly typed columns in the same table.
E. Use Snowflake's VARIANT data type for a single column in the Snowflake table. Load the entire CSV file content as a JSON string into this column. Create views to extract and cast the data based on the 'record_type'.

Answer: A

Explanation:
The most efficient and scalable method involves creating multiple Snowflake tables, one for each 'record_type'. Loading data into correctly typed tables, using a task to dynamically identify files and load them into the appropriate table, leverages Snowflake's strengths. While VARIANT can store different schemas, querying and processing data in VARIANT columns are less performant than querying and processing data with correct data types. A single wide table with all VARCHAR columns requires extensive casting in views. External tables with streams can work, but creating multiple tasks for each record type becomes complex. Choosing the correct data type at load time and having well-defined schemas will minimize transformation later.

NEW QUESTION # 21
Which action is essential in performing exploratory ad-hoc analyses?

A. Analyzing a small subset of the available data
B. Relying solely on predefined queries without exploration
C. Focusing solely on established trends without investigating anomalies
D. Utilizing ad-hoc queries to examine patterns and anomalies

Answer: D

Explanation:
Ad-hoc analysis involves using queries to explore patterns and anomalies beyond predefined routines.

NEW QUESTION # 22
You have a Snowsight dashboard that visualizes daily sales trends. Business users complain that the dashboard takes too long to load, especially when filtering by specific product categories. The underlying data resides in a large table partitioned by 'sale date'. Which of the following actions would BEST improve the dashboard's performance, assuming the filters are appropriately configured in the dashboard and the virtual warehouse size is already appropriately sized?

A. Increase the virtual warehouse size used by Snowsight.
B. Create a materialized view that pre-aggregates the data used by the dashboard, including the dimensions used in the filters.
C. Convert the dashboard into a Streamlit application for improved rendering performance.
D. Use query acceleration on the base table to improve the speed of underlying queries when the filter are being applied by users.
E. Implement result caching by setting = TRUE at the session level.

Answer: B

Explanation:
Creating a materialized view pre-aggregates the data, significantly reducing query execution time. The materialized view stores the result of a query, and Snowflake automatically refreshes it when the underlying data changes. Since the product categories are used as filters, pre- aggregating along these dimensions directly addresses the slow loading times. Increasing warehouse size (B) only helps if the compute resources are a bottleneck, which might not be the primary issue. Converting to Streamlit (C) changes the presentation layer but doesn't inherently improve data retrieval. Query Acceleration (D) can help, but only if it properly sized and configured. Session level caching (E) might only benefit the same user, but if multiple users are accessing the same dashboard, the best way would be through pre-aggregated results in a materialized view.

NEW QUESTION # 23
What critical role do user-defined functions (UDFs) play in SQL for advanced data analysis?

A. UDFs hinder query optimization in SQL.
B. UDFs only handle basic data manipulation tasks.
C. They enable customized operations on data, extending SQL functionalities.
D. UDFs are limited to specific data types.

Answer: C

Explanation:
UDFs extend SQL functionalities by enabling customized operations on data, going beyond standard SQL capabilities.
