A user is loading JSON documents composed of a huge array containing multiple records into Snowflake.
The user enables the strip__outer_array file format option
What does the STRIP_OUTER_ARRAY file format do?
Answer: A
Explanation:
The STRIP_OUTER_ARRAY file format option in Snowflake is used when loading JSON documents that are composed of a large array containing multiple records. When this option is enabled, it removes the outer array structure, which allows each record within the array to be loaded as a separate row in the table. This is particularly useful for efficiently loading JSON data that is structured as an array of records1.

NEW QUESTION # 277
The fail-safe retention period is how many days?
Answer: D
Explanation:
Fail-safe is a feature in Snowflake that provides an additional layer of data protection. After the Time Travel retention period ends, Fail-safe offers a non-configurable 7-day period during which historical data may be recoverable by Snowflake. This period is designed to protect against accidental data loss and is not intended for customer access.

NEW QUESTION # 278
Which Snowflake layer is associated with virtual warehouses?
Answer: A
Explanation:
The layer of Snowflake ' s architecture associated with virtual warehouses is the Query Processing layer.
Virtual warehouses in Snowflake are dedicated compute clusters that execute SQL queries against the stored data. This layer is responsible for the entire query execution process, including parsing, optimization, and the actual computation. It operates independently of the storage layer, enabling Snowflake to scale compute and storage resources separately for efficiency and cost-effectiveness.

NEW QUESTION # 279
A developer expects Snowflake to refresh a dynamic table incrementally, but Snowflake selects full refresh mode instead.
Which query operator can prevent incremental refresh and cause Snowflake to use full refresh mode when REFRESH_MODE = AUTO?
Answer: A
Explanation:
Snowflake supports incremental refresh for many common query constructs, including supported uses of DISTINCT, GROUP BY, and UNION ALL.
General lateral joins are not supported for incremental dynamic-table refresh. A documented exception exists for supported uses of LATERAL FLATTEN.
When a dynamic table is created with REFRESH_MODE = AUTO, Snowflake analyzes the defining query.
When the query cannot be refreshed incrementally, Snowflake can choose full refresh mode.
When REFRESH_MODE = INCREMENTAL is explicitly requested and the query contains an unsupported construct, dynamic-table creation can fail instead of silently changing the requested refresh mode.

NEW QUESTION # 280
A user needs to MINIMIZE the cost of large tables that are used to store transitory data. The data does not need to be protected against failures, because the data can be reconstructed outside of Snowflake.
What table type should be used?
Answer: D
Explanation:
For minimizing the cost of large tables that are used to store transitory data, which does not need to be protected against failures because it can be reconstructed outside of Snowflake, the best table type to use isTransient. Transient tables in Snowflake are designed for temporary or transitory data storage and offer reduced storage costs compared to permanent tables. However, unlike temporary tables, they persist across sessions until explicitly dropped.
Why Transient Tables:Transient tables provide a cost-effective solution for storing data that is temporary but needs to be available longer than a single session. They have lower data storage costs because Snowflake does not maintain historical data (Time Travel) for as long as it does for permanent tables.
Creating a Transient Table:
To create a transient table, use theTRANSIENTkeyword in the CREATE TABLE statement:
CREATETRANSIENTTABLEmy_transient_table (...);
Use Case Considerations:Transient tables are ideal for scenarios where the data is not critical, can be easily recreated, and where cost optimization is a priority. They are suitable for development, testing, or staging environments where data longevity is not a concern.
Reference:For more details on transient tables and their usage scenarios, refer to the Snowflake documentation on table types: https://docs.snowflake.com/en/sql-reference/sql/create-table.html#table-types
