Snowflake SnowPro Advanced: Data Analyst Certification Exam Sample Questions (Q44-Q49):

NEW QUESTION # 44
How does the utilization of Regular views differ from Materialized views in data analysis?

A. Materialized views provide a persisted snapshot, unlike Regular views.
B. Materialized views offer limited data accessibility compared to Regular views.
C. Regular views are exclusively used for exploratory analyses.
D. Regular views offer better query performance compared to Materialized views.

Answer: A

Explanation:
Materialized views provide a persisted snapshot of data, differentiating them from Regular views.

NEW QUESTION # 45
Why is the Parquet format preferred for complex data sets?

A. It supports efficient compression and encoding schemes
B. It changes data colors for differentiation
C. It has visually appealing data presentation
D. It randomly alters data for testing

Answer: A

NEW QUESTION # 46
A marketing company is analyzing customer purchase data stored in Snowflake to understand which customer demographics are most likely to purchase a newly launched product. The 'CUSTOMERS table has columns: 'customer_id', 'age' , 'gender' , 'location' , and 'household income'. The 'PURCHASES' table has columns: 'customer_id', 'purchase_date', and 'product id'. Which SQL query would most effectively identify the top three age groups with the highest purchase rate for the new product (product_id = 'NEW PRODUCT')?

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

Answer: B

Explanation:
Option D is the most effective because it calculates the purchase rate by dividing the count of distinct customers who purchased the new product by the total number of customers in each age group. This provides a normalized purchase rate for each age group, allowing for a fair comparison regardless of the size of each group. Options A and C only provide the raw count of purchases or unique purchasers, which doesn't account for the size of each age group. Option B uses 'SUM(CASE...V , which can work, but is less efficient than using 'COUNT(DISTINCTV in combination with a left join to account for all customers, even those who didn't make any purchases. Option E would produce an incorrect rate as it is dividing a customer's count by the distinct count of each customer, resulting in a rate close to 1.0 for each customer that made a purchase.

NEW QUESTION # 47
How does leveraging partition pruning enhance query performance in Snowflake?

A. Speeds up data loading processes significantly
B. Optimizes query planning by eliminating unnecessary partitions
C. Reduces metadata storage requirements
D. Limits data access for specific user roles

Answer: B

Explanation:
Partition pruning optimizes query planning by excluding unnecessary partitions from query execution, improving query performance by focusing on relevant data subsets.

NEW QUESTION # 48
The following code is run:

Then this statement is executed:

What will be the output of this statement?

Answer: D

Explanation:
To determine the correct output, a Data Analyst must understand the behavior of the ILIKE operator, wildcard characters, and the ESCAPE clause in Snowflake.
