At ValidExamDumps, we consistently monitor updates to the Snowflake DSA-C02 exam questions by Snowflake. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Snowflake SnowPro Advanced: Data Scientist Certification Exam exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Snowflake in their Snowflake DSA-C02 exam. These outdated questions lead to customers failing their Snowflake SnowPro Advanced: Data Scientist Certification Exam exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Snowflake DSA-C02 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
A Data Scientist as data providers require to allow consumers to access all databases and database objects in a share by granting a single privilege on shared databases. Which one is incorrect SnowSQL command used by her while doing this task?
Assuming:
A database named product_db exists with a schema named product_agg and a table named Item_agg.
The database, schema, and table will be shared with two accounts named xy12345 and yz23456.
1. USE ROLE accountadmin;
2. CREATE DIRECT SHARE product_s;
3. GRANT USAGE ON DATABASE product_db TO SHARE product_s;
4. GRANT USAGE ON SCHEMA product_db. product_agg TO SHARE product_s;
5. GRANT SELECT ON TABLE sales_db. product_agg.Item_agg TO SHARE product_s;
6. SHOW GRANTS TO SHARE product_s;
7. ALTER SHARE product_s ADD ACCOUNTS=xy12345, yz23456;
8. SHOW GRANTS OF SHARE product_s;
CREATE SHARE product_s is the correct Snowsql command to create Share object.
Rest are correct ones.

Which one of the following is not the key component while designing External functions within Snowflake?
What is an External Function?
An external function calls code that is executed outside Snowflake.
The remotely executed code is known as a remote service.
Information sent to a remote service is usually relayed through a proxy service.
Snowflake stores security-related external function information in an API integration.
External Function:
An external function is a type of UDF. Unlike other UDFs, an external function does not contain its own code; instead, the external function calls code that is stored and executed outside Snowflake.
Inside Snowflake, the external function is stored as a database object that contains information that Snowflake uses to call the remote service. This stored information includes the URL of the proxy service that relays information to and from the remote service.
Remote Service:
The remotely executed code is known as a remote service.
The remote service must act like a function. For example, it must return a value.
Snowflake supports scalar external functions; the remote service must return exactly one row for each row received.
Proxy Service:
Snowflake does not call a remote service directly. Instead, Snowflake calls a proxy service, which relays the data to the remote service.
The proxy service can increase security by authenticating requests to the remote service.
The proxy service can support subscription-based billing for a remote service. For example, the proxy service can verify that a caller to the remote service is a paid subscriber.
The proxy service also relays the response from the remote service back to Snowflake.
Examples of proxy services include:
Amazon API Gateway.
Microsoft Azure API Management service.
API Integration:
An integration is a Snowflake object that provides an interface between Snowflake and third-party services. An API integration stores information, such as security information, that is needed to work with a proxy service or remote service.
An API integration is created with the CREATE API INTEGRATION command.
Users can write and call their own remote services, or call remote services written by third parties. These remote services can be written using any HTTP server stack, including cloud serverless compute services such as AWS Lambda.
What is the formula for measuring skewness in a dataset?
Since the normal curve is symmetric about its mean, its skewness is zero. This is a theoretical expla-nation for mathematical proofs, you can refer to books or websites that speak on the same in detail.
Mark the Incorrect statements regarding MIN / MAX Functions?
NULL values are ignored unless all the records are NULL, in which case a NULL value is returned
Which of the Following is not type of Windows function in Snowflake?
Window Functions
A window function operates on a group (''window'') of related rows.
Each time a window function is called, it is passed a row (the current row in the window) and the window of rows that contain the current row. The window function returns one output row for each input row. The output depends on the individual row passed to the function and the values of the other rows in the window passed to the function.
Some window functions are order-sensitive. There are two main types of order-sensitive window functions:
Rank-related functions.
Window frame functions.
Rank-related functions list information based on the ''rank'' of a row. For example, if you rank stores in descending order by profit per year, the store with the most profit will be ranked 1; the second-most profitable store will be ranked 2, etc.
Window frame functions allow you to perform rolling operations, such as calculating a running total or a moving average, on a subset of the rows in the window.
