NO.15 You’re tasked with creating a Snowsight dashboard to monitor the performance of different ETL pipelines. The dashboard needs to display the average run time and the number of errors for each pipeline over the last 7 days. The data is stored in a table called ‘ETL LOGS’ with columns ‘end_time’, and ‘error_flag’ (boolean). You need to present this information in a way that users can easily compare the performance of different pipelines. Which of the following SQL queries, used as the basis for a Snowsight tile, would be MOST appropriate for this dashboard?

NO.16 You’re working with product catalog data in Snowflake. The product information is stored in a table named ‘PRODUCTS’ , and a key attribute, ‘attributes’ , contains a semi-structured JSON object for each product. This ‘attributes’ object can have varying keys, but you are interested in extracting specific keys and pivoting them into columns. The relevant JSON structure is as follows : { “color”: “red”, “size”: “L”, “material”: “cotton”, “style”: “casual”} ‘”What method is the MOST efficient to transform this data to a relational structure, assuming you want to analyze product attributes such as ‘color’ and ‘size’ as separate columns?

NO.17 When handling erroneous data in Snowflake, what approaches can be employed to effectively address data anomalies and ensure data integrity? (Select all that apply)

NO.18 A Data Analyst wants to transform query results. Which transformation option will incur compute costs?

NO.19 The following code is run:

Then this statement is executed:

What will be the output of this statement?

NO.20 What distinguishes Materialized views from Secure views in the context of data analysis?

NO.21 You are tasked with analyzing website clickstream data stored in a Snowflake table called ‘clickstream_events’. Each row represents a click event and contains a ‘session_id’ , and a ‘properties’ column of type VARIANT that stores key-value pairs related to the event (e.g., ‘(page’: ‘[product/123’, ‘element’: You need to extract the ‘page’ and ‘element’ values from the ‘properties’ column and identify the most common ‘page’-‘element’ combinations for each ‘session_id’. Furthermore you need to limit the results of your data to the top 5 pages element pair. How can this task be accomplished using Snowflake table functions and analytical functions?

NO.23 You are a data analyst for an e-commerce company. You need to create a dashboard visualizing sales performance. The dashboard requires two key features: 1) users should be able to filter the data by product category dynamically using a dropdown list. 2) The dashboard should efficiently handle large datasets (millions of rows) without performance degradation. Which Snowflake features and techniques would you use to achieve these requirements most effectively?

NO.24 You have a stored procedure written in Python within Snowflake that needs to process a large dataset. The procedure’s performance is critical, and you want to optimize it for speed. Which of the following strategies would be MOST effective in improving the performance of your Python stored procedure when dealing with large datasets in Snowflake? (Select TWO)

NO.25 When cleaning data, what role does using clones play in specific use-cases?

NO.26 You are tasked with designing a Snowflake data model for a system that tracks changes to product information. You need to store both the current and historical states of the ‘PRODUCTS’ table. Which of the following strategies, regarding primary keys and table structures, is the MOST appropriate for efficiently querying the current product state and historical changes, considering best practices for Snowflake and minimizing storage costs? Select all that apply.

NO.27 When planning for data volume collection, what is an important consideration to ensure scalability and performance?

NO.28 A Data Analyst is working with three tables:

Which query would return a list of all brokers, a count of the customers each broker has. and the total order amount of their customers (as shown below)?

NO.29 When evaluating and selecting data for building dashboards, what factors should be considered for ensuring data relevance and usefulness? (Select all that apply)

NO.30 How does leveraging Time Travel feature in Snowflake aid in query optimization and historical data analysis?

NO.31 You are tasked with loading data from a REST API that returns data in a deeply nested JSON format. The API requires authentication via an API key passed in the header. The JSON response contains an array of objects, each representing a customer order. You need to load only orders placed in the last 7 days. Which of the following steps and techniques would you use in Snowflake to achieve this?

NO.32 When maintaining reports and dashboards, why is it crucial to configure subscriptions and updates?

NO.33 There are two similarly-structured and sized tables, Table_a and Table_b, in a schema with data populated in both tables. A Data Analyst is running queries as part of a preliminary analysis of the data to check the MAX value of a numeric column named num which is present in both the tables:
* Query 1: SELECT MAX(num) FROM Table_a;
* Query 2: SELECT MAX(num) FROM Table_b;
After running the queries, the Analyst observed that Query 2 ran significantly slower than Query 1. Why is this occurring?

NO.34 You are working with a table ‘ORDERS’ containing order data, and a table ‘CUSTOMER SEGMENTS containing customer segment information. The ‘ORDERS’ table has columns ‘ORDER ID’, ‘CUSTOMER ID, and ‘ORDER AMOUNT’. The ‘CUSTOMER SEGMENTS’ table has columns ‘CUSTOMER ID’, ‘SEGMENT ID’, and ‘SEGMENT NAME’. You need to create a query that enriches the ‘ORDERS’ table with the customer segment information. However, a customer can belong to multiple segments. You want to include all segments a customer belongs to in the enriched data, resulting in potentially multiple rows per order if the customer is in multiple segments. The output should include ‘ORDER ID, ‘ORDER AMOUNT, ‘SEGMENT ID’, and ‘SEGMENT NAMES. Which SQL statement would correctly enrich the ORDERS table without losing any order information, even if customers belong to multiple segments?

NO.35 A Data Analyst needs to temporarily hide a tile in a dashboard. The data will need to be available in the future, and additional data may be added. Which tile should be used?

NO.36 You are creating a Snowsight dashboard to display the results of an A/B test on a website. You have the following tables: (columns: ‘USER_ID’, ‘VARIANT’ (VARCHAR, either ‘A’ or ‘B’), ‘CONVERSION’ (BOOLEAN), ‘TIMESTAMP’) ‘USER DEMOGRAPHICS’ (columns: ‘USER_ID, ‘REGION’, ‘DEVICE) The stakeholders want to see the following visualizations: 1. Overall conversion rate for each variant. 2. Conversion rate for each variant broken down by region. 3. A table showing the statistical significance (p-value) of the difference in conversion rates between variants for each region, using a Chi-Square test. (Assume you have access to a stored procedure CHI SQUARE TEST(variant_a_conversions INT, variant_a_total INT, variant_b_conversions INT, variant b total INT) that returns the p-value.) Which combination of queries and Snowsight features will achieve the desired outcome with optimal performance and maintainability?
