Snowflake SnowPro Advanced: Data Analyst Certification Exam Sample Questions (Q25-Q30):

NEW QUESTION # 25
A single variant data column table RAW_SOURCE has the following JSON records:

A Data Analyst needs to get the value of the "f" field and have it in a consumable, tabular format. Which query should be used to meet this requirement?

A. select src.events:f::number from raw_source src;
B. select value:f::number from raw_source, lateral flatten( input => data:events );
C. select data:events:f::number from raw_source;
D. select value:f::number from raw_source, lateral flatten( input => data );

Answer: B

Explanation:
Working with nested semi-structured data requires a deep understanding of Snowflake's FLATTEN function and path notation. In the provided JSON exhibit, the data is hierarchical: the root contains a key named
"events", which is an array containing multiple objects. Each object within that array contains the target field
"f".
To transform this into a "consumable, tabular format" where each instance of "f" appears as a separate row, the Data Analyst must "explode" the array. Simply using path notation like data:events:f (Option A) will fail or return NULL because the engine cannot directly map a single path through an array structure to multiple scalar results without an explicit relational transformation.
The LATERAL FLATTEN function is the standard tool for this task. It takes a semi-structured column (or a specific path within it) as an input and returns a relational result set. By specifying input => data:events, the Analyst instructs Snowflake to look specifically at the array. For every element found in that array, FLATTEN generates a new row in the result set. The output of the flatten operation includes a column named VALUE, which represents the specific element (in this case, an object) currently being processed.
Evaluating the Options:
* Option A and C are incorrect because they attempt to use direct pathing on an array. Without flattening, the query engine sees the array as a single block of data and cannot reach the "f" key inside individual array elements.
* Option B is incorrect because it flattens the root data object. While this works for top-level keys, it wouldn't automatically iterate through the "events" array to expose the "f" values inside it; it would treat the entire array as a single value.
* Option D is the 100% correct answer. It correctly targets the "events" array for flattening and then utilizes path notation (value:f) followed by the appropriate type casting (::number) to produce the final tabular output. This is a core competency for any SnowPro Advanced Data Analyst handling modern telemetry or event-based data.

NEW QUESTION # 26
You have developed a Snowsight dashboard for your marketing team that contains sensitive customer data'. You need to share this dashboard with a specific group of users, but ensure that they can only view the data and cannot modify the dashboard itself or the underlying queries. Which of the following steps should you take to securely share the dashboard?

A. Share the dashboard with the group using the 'Can edit' permission. Then, grant the users in the group the 'USAGE' privilege on the database and schema containing the data.
B. Share the dashboard with the group using the 'Can view' permission. Ensure the group has the 'SELECT' privilege on the tables/views used in the queries and the ' USAGE privilege on the database and schema. Also ensure that any intermediate tables created by the dashboard are also granted these privleges.
C. Create a scheduled task to export the dashboard as a PDF and email it to the group on a daily basis.
D. Share the dashboard with 'Can view' permission and no further action is required.
E. Share the dashboard with the group using the 'Can view' permission. Then, grant the users in the group the 'MONITOR privilege on the virtual warehouse used by Snowsight.

Answer: B

Explanation:
Sharing with 'Can view' (B) ensures the users cannot modify the dashboard itself. Granting 'SELECT on the underlying tables/views and USAGE' on the database/schema allows them to see the data when the dashboard executes queries on their behalf. 'Can edit' (A) would allow them to modify the dashboard, which is not desired. 'MONITOR (C) is for monitoring warehouse usage, not data access. Exporting as PDF (D) is a workaround, but it loses interactivity and isn't a direct sharing method. E isn't correct because permissions on the data sources must be granted separately.

NEW QUESTION # 27
Consider a scenario where you have a table 'CUSTOMER ORDERS' with columns 'CUSTOMER ID', 'ORDER DATE' , 'ORDER TOTAL' , and 'PRODUCT CATEGORY'. You want to create a materialized view that calculates the sum of order totals for each customer, grouped by product category, and refreshed automatically on a daily basis. However, you are also concerned about minimizing the cost of materialized view maintenance. Which of the following strategies would be MOST cost-effective while still providing reasonably up-to-date data?

A. Create a materialized view and set the refresh schedule to 'ON CHANGE'.
B. Create a materialized view without specifying a refresh schedule, and manually refresh it whenever the report is run.
C. Create a materialized view and schedule a daily refresh at a time of low system activity.
D. Create a materialized view and set the refresh schedule to 'ON CHANGE' with a clustering key on
E. Create a standard view with the same aggregation logic and optimize the underlying table using clustering.

Answer: C

Explanation:
Scheduling a daily refresh allows the materialized view to be updated regularly without incurring the overhead of 'ON CHANGE' refreshes, which can be very costly if the underlying table is frequently updated. Manual refreshes would not provide up-to-date data automatically. 'ON CHANGE' without further optimization can be extremely expensive. A standard view wouldn't provide the performance benefits of a materialized view. Clustering on CUSTOMER ID might improve performance but would not address the refresh cost directly.

NEW QUESTION # 28
You are working with a large dataset of website clickstream data'. You need to perform several data transformation steps, including filtering, aggregating, and joining with other tables. You want to ensure that your data cleaning and transformation process is idempotent, meaning that running the same transformation pipeline multiple times will produce the same result, even if the input data changes slightly. Which of the following strategies contribute to building an idempotent data transformation pipeline in Snowflake? (Select all that apply)

A. Always truncating the target table before inserting transformed data.
B. Using temporary tables instead of permanent tables for transformation.
C. Relying solely on 'INSERT INTO' statements for data loading.
D. Using clones of source tables as input to the transformation pipeline, ensuring that the source data remains unchanged during the process.
E. Using 'MERGE statements with appropriate matching conditions to update or insert records based on the latest data.

Answer: A,D,E

Explanation:
Options A, B, and D are correct. Truncating the target table (A) before each run ensures a clean slate. Using 'MERGE statements (B) handles both updates and inserts, ensuring that the target table reflects the latest data state regardless of previous runs. Using clones (D) protects the original source data from unintended modifications during the transformation process, contributing to idempotency. Option C using just INSERT INTO is not idempotent as it will duplicate data on rerun. Option E, while useful for performance and cleanup, doesn't directly contribute to idempotency. The use of temporary tables alone does not guarantee idempotency if the operations performed on them are not idempotent. You might still see inconsistencies in data if the operations are not carefully designed. Truncating permanent table before adding data using MERGE is more reliable and ensures consistent result even on multiple runs.

NEW QUESTION # 29
What factors should be considered when evaluating which transformations are required in data discovery? (Select all that apply)

A. Data normalization
B. Data redundancy
C. Business use cases
D. Data consistency

Answer: A,C,D

Explanation:
Evaluating necessary transformations involves considering data consistency, normalization, and alignment with business use cases.
