149. Frage
What task can a data consumer perform using third-party datasets from the Snowflake Marketplace?
Antwort: B
Begründung:
Snowflake Marketplace allows consumers to discover and access third-party datasets without building separate ingestion pipelines for each provider. Consumers can combine Marketplace data with data already stored in their Snowflake environment and query the combined information to produce new analytics and business insights. The provider continues to control and update the shared data product, while the consumer generally receives read-only access through a listing. Consumers cannot modify the provider's underlying schemas or source data, and imported shared databases cannot be re-shared as the consumer's own listing. Exporting data to local files is not the defining Marketplace capability described in this question. Therefore, integrating third-party Marketplace data with the consumer's existing Snowflake data is the supported task represented by option B.
150. Frage
Network policies can be applied to which of the following Snowflake objects? (Choose two.)
Antwort: D,E
Begründung:
Network policies in Snowflake can be applied to users and accounts.These policies control inbound access to the Snowflake service and internal stages, allowing or denying access based on the originating network identifiers12.

151. Frage
A column named "Data" contains VARIANT data and stores values as follows:
How will Snowflake extract the employee's name from the column data?
Antwort: B
Begründung:
In Snowflake, to extract a specific value from a VARIANT column, you use the column name followed by a colon and then the key. The keys are case-sensitive. Therefore, to extract the employee's name from the "Data" column, the correct syntax is data:employee.name.
152. Frage
What is a key difference between JSON and CSV file formats when loading data? Select TWO.
Antwort: A,D
Begründung:
The correct answers are A. CSV stores flat, tabular data and E. JSON can be loaded into a VARIANT column without predefined schema .
Important correction:
The provided answer A, B is not correct. CSV does not natively support complex semi-structured data types such as arrays and objects. JSON does.
Why A is correct:
CSV is a delimited, flat file format commonly used for structured, tabular data. Each row usually represents a record, and each field is separated by a delimiter such as a comma.
Why E is correct:
JSON is semi-structured data and can be loaded into a Snowflake VARIANT column. This allows Snowflake to store JSON objects and arrays without requiring every nested field to be predefined as a relational column.
Example:
CREATE TABLE json_data (
src VARIANT
);
COPY INTO json_data
FROM @my_stage
FILE_FORMAT = (TYPE = JSON);
Why the other options are incorrect:
B). CSV does not natively support arrays and objects. JSON supports nested structures such as arrays and objects.
C). JSON does not need to be converted to CSV before it can be queried in Snowflake. Snowflake can query JSON data stored in VARIANT, OBJECT, or ARRAY columns.
D). CSV files do not automatically detect and apply Snowflake table data types during loading. The target table schema and file format options control how data is interpreted.
Official Snowflake documentation reference:
Snowflake documentation explains that CSV is used for structured data, while semi-structured formats such as JSON can be loaded into VARIANT columns and queried using semi-structured data syntax.
