Explanation:

Explanation:

In Snowflake, Data Shares can be created and managed in two primary ways:

Via the Snowflake Web Interface (UI): Users can create and manage shares through the graphical interface provided by Snowflake, which allows for a user-friendly experience.
Via SQL commands: Snowflake also allows the creation and management of shares using SQL commands. This method is more suited for users who prefer scripting or need to automate the process.

Options:

A User Defined Function (UDF)

A stored procedure

A single copy_into statement

A single insert__into statement

Discussion

Answer:

Explanation:

Explanation:

Snowpipe is used for continuous, automated data loading into Snowflake. It uses a COPY INTO

statement within a pipe object to load data from files as soon as they are available in a stage. Snowpipe does not execute UDFs, stored procedures, or insert statements. References: Snowpipe | Snowflake Documentation

Question 158

Which of the following is a valid source for an external stage when the Snowflake account is located on Microsoft Azure?

Options:

An FTP server with TLS encryption

An HTTPS server with WebDAV

A Google Cloud storage bucket

A Windows server file share on Azure

Discussion

Answer:

Explanation:

Explanation:

In Snowflake, when the account is located on Microsoft Azure, a valid source for an external stage can be an Azure container or a folder path within an Azure container. This includes Azure Blob storage which is accessible via the azure:// endpoint. A Windows server file share on Azure, if configured properly, can be a valid source for staging data files for Snowflake. Options A, B, and C are not supported as direct sources for an external stage in Snowflake on Azure12. References: [COF-C02] SnowPro Core Certification Exam Study Guide

Question 159

A user has 10 files in a stage containing new customer data. The ingest operation completes with no errors, using the following command:

COPY INTO my__table FROM @my__stage;

The next day the user adds 10 files to the stage so that now the stage contains a mixture of new customer data and updates to the previous data. The user did not remove the 10 original files.

If the user runs the same copy into command what will happen?

Options:

All data from all of the files on the stage will be appended to the table

Only data about new customers from the new files will be appended to the table

The operation will fail with the error uncertain files in stage.

All data from only the newly-added files will be appended to the table.

Discussion

Answer:

Explanation:

Explanation:

When the COPY INTO command is executed in Snowflake, it processes all files present in the specified stage that have not been ingested before or marked as already loaded. Since the user did not remove the original 10 files after the first load, running the same COPY INTO command again will result in all 20 files being processed. This means that the data from the original 10 files will be appended to the table again, along with the data from the new 10 files, potentially leading to duplicate records for the original data set.
