Snowflake SnowPro Advanced: Data Analyst Certification Exam Sample Questions (Q46-Q51):

NEW QUESTION # 46
In data presentations for business use analyses, what significance do identifying patterns and trends hold?

A. Patterns and trends don't impact business use analyses significantly.
B. Identifying patterns and trends aids in insightful analyses.
C. Recognizing patterns and trends limits data exploration.
D. It complicates data analysis, hindering decision-making.

Answer: B

Explanation:
Identifying patterns and trends aids in insightful analyses in business use scenarios.

NEW QUESTION # 47
What does the "SQL keyword" refer to in the context of adding filters to a worksheet?

A. The name of the function used to generate the filter
B. The filter name to be inserted into queries
C. The table name containing the static filter "key" values
D. The name of a User-Defined Function (UDF) used to define the filter "key" values

Answer: B

Explanation:
In Snowsight (Snowflake's web interface), Data Analysts can create interactive dashboards and worksheets using Filters. When you define a filter (such as a Date Range or a list of Regions), you must assign it a SQL Keyword.
This "SQL Keyword" acts as a variable placeholder within your SQL code. For example, if you create a filter for "Customer Region" and set the SQL keyword to :my_region, you can then write a query like:
SELECT * FROM sales WHERE region = :my_region. When a user interacts with the UI and selects "North America" from the dropdown, Snowsight automatically injects "North America" into every instance where :
my_region appears in the worksheet's SQL.
Evaluating the Options:
* Option A is incorrect because the keyword is a label/variable, not the underlying function code.
* Option C and Option D are incorrect as they confuse the data source of the filter values with the reference name used in the SQL code.
* Option B is the correct answer. The SQL Keyword is specifically the identifier (prefixed with a colon in the code) that allows the analyst to link the UI element (the filter) to the execution logic of the query.
This is a fundamental skill for the Data Presentation and Data Visualization domain, ensuring reports are dynamic and user-friendly.

NEW QUESTION # 48
You are tasked with ingesting data from a REST API that provides daily sales reports in JSON format. The API has rate limits (100 requests per minute) and returns a large dataset (approximately 5GB per day). The data needs to be processed within 2 hours of its availability. You want to leverage Snowflake external functions and tasks. Which approach balances efficiency, cost, and adherence to rate limits?

A. Call API directly from a scheduled task without considering Rate Limit. Persist the data using COPY INTO command.
B. Create a single Snowflake task that calls an external function which iterates through all API pages sequentially in a single execution to retrieve and load all the data. Rely on Snowflake's automatic scaling to handle the load.
C. Create a Snowflake external function that directly connects to the API and loads data into a staging table. Use Snowpipe with auto-ingest to continuously load the data as it arrives. Ignore the API Rate limits; assume they will be handled by API itself.
D. Create a Snowflake task that calls an external function. This external function calls an intermediate service (e.g., AWS Lambda, Azure Function) which is responsible for fetching the data in batches, respecting the API rate limits, and storing the data in cloud storage. Snowpipe then loads the data from cloud storage into Snowflake.
E. Create a Snowflake task that triggers an external function which retrieves only the metadata (e.g., total records, page count) from the API. Then, create a dynamic number of child tasks, each responsible for retrieving a subset of the data, using the metadata to respect the API rate limits.

Answer: D

Explanation:
Option D is the most balanced approach. It leverages an intermediate service to handle the complexities of API interaction (rate limits, pagination), decouples the data retrieval from Snowflake compute, and uses Snowpipe for efficient bulk loading. This approach addresses I both the rate limits and processing time requirements effectively.

NEW QUESTION # 49
How do row access policies and Dynamic Data Masking affect the creation and maintenance of reports and dashboards?

A. They enhance data visibility without any restrictions.
B. Row access policies limit data visibility based on user privileges.
C. Dynamic Data Masking doesn't impact dashboard creation or maintenance.
D. Both policies restrict data visibility for better security.

Answer: B

Explanation:
Row access policies restrict data visibility based on user privileges, ensuring better security in creation and maintenance of reports and dashboards.

NEW QUESTION # 50
What is the primary benefit of connecting BI tools to Snowflake for dashboard creation?

A. BI tools restrict dashboard customization
B. Improved data security in dashboards
C. Simplified data access for all users
D. Seamless integration and data visualization

Answer: D

Explanation:
Connecting BI tools to Snowflake enables seamless integration and data visualization in dashboard creation.
