NEW QUESTION # 787
What is a recommended best practice when loading data into Snowflake?
Answer: C
Explanation:
To optimize parallelism and maximize performance, large files should be split into multiple smaller files (ideally 100-250 MB compressed) before loading. This allows Snowflake to load files in parallel using multiple threads or clusters.

NEW QUESTION # 788
How does Snowflake Fail-safe protect data in a permanent table?
Answer: D
Explanation:
Snowflake's Fail-safe provides a 7-day period during which data in a permanent table may be recoverable, but only by Snowflake Support, not by user operations3.
NEW QUESTION # 789
Where can file formats be specified when unloading data from Snowflake? Select TWO.
Answer: C,D
Explanation:
The correct answers are B. In a CREATE STAGE statement and E. In a COPY INTO < location > statement .
When unloading data from Snowflake, file format options can be specified directly in the COPY INTO < location > command or associated with a named stage. Defining the file format in a stage is useful when repeated loads or unloads use the same format settings.
Why B is correct:
A stage can include a file format definition or reference. When data is unloaded to that stage, the file format associated with the stage can be used.
Example:
CREATE STAGE my_stage
FILE_FORMAT = (TYPE = CSV FIELD_DELIMITER = ' , ' );
COPY INTO @my_stage
FROM my_table;
Why E is correct:
The COPY INTO < location > command can specify file format options directly.
Example:
COPY INTO @my_stage/output/
FROM my_table
FILE_FORMAT = (TYPE = CSV COMPRESSION = GZIP);
Why the other options are incorrect:
A). A SELECT statement defines the query result to unload, but file format options are not specified as part of a normal SELECT.
C). A database definition does not define unload file format options.
D). An integration defines access to external services or storage, not the file format used for unloading.
Official Snowflake documentation reference:
Snowflake documentation explains that file format options can be specified in the COPY INTO < location > command or as part of a named stage definition.
Reference: Snowflake Documentation - COPY INTO < location > ; Snowflake Documentation - CREATE STAGE; Snowflake Documentation - File formats; SnowPro Core Study Guide - Data Loading and Unloading.

NEW QUESTION # 790
How can the Query Profile be used to troubleshoot a problematic query?
Answer: D
Explanation:
The Query Profile in Snowflake provides detailed insights into the execution of a query. It helps in troubleshooting performance issues by showing the steps of the query execution and the resources consumed.
One of the key aspects it reveals is whether the virtual warehouse memory was sufficient for the query.
Access Query Profile:Navigate to the Query History page and select the query you want to analyze.
Examine Query Execution Steps:The Query Profile displays the different stages of the query execution, including the time taken and resources used at each step.
Identify Memory Issues:Look for indicators of memory issues, such as spilling to disk or memory errors, which suggest that the virtual warehouse memory might be too small.
