NEW QUESTION # 778
How should the SPLIT_TO_TABLE(<string>, <delimiter>) function be called?
Answer: B
Explanation:
SPLIT_TO_TABLE() is a table function that splits a string into multiple rows based on a delimiter. To use it correctly in SQL, you must wrap it in a TABLE() clause.
Correct Syntax:
SELECT * FROM TABLE(SPLIT_TO_TABLE('a.b.c', '.'));

NEW QUESTION # 779
A user created a transient table and made several changes to it over the course of several days. Three days after the table was created, the user would like to go back to the first version of the table.
How can this be accomplished?
Answer: A
Explanation:
To go back to the first version of a transient table created three days prior, one can use Time Travel if the DATA_RETENTION_TIME_IN_DAYS was set to at least 3 days. This allows the user to access historical data within the specified retention period. References: [COF-C02] SnowPro Core Certification Exam Study Guide
NEW QUESTION # 780
What actions can be taken to reduce memory spilling for queries that are too large to fit into memory? Select TWO.
Answer: C,D
Explanation:
The correct answers are A. Increase the size of the virtual warehouse and B. Edit the queries to process the data in smaller batches .
Memory spilling occurs when a query requires more memory than is available in the virtual warehouse.
Snowflake may spill intermediate data to local or remote storage, which can slow query performance.
Why A is correct:
Increasing the warehouse size provides more compute and memory resources. This can reduce or eliminate spilling for memory-intensive queries.
Why B is correct:
Rewriting queries to process data in smaller batches reduces the amount of intermediate data held in memory at one time. This can reduce spilling and improve performance.
Important note about option C:
Option C is misleading because a virtual warehouse cluster's size is changed by increasing the warehouse size
. Since option A already says this correctly, option C is not the best answer.
Why the other options are incorrect:
C). "Increase the size of the virtual warehouse clusters" is essentially a less precise duplicate of increasing warehouse size. The exam-style answer is A.
D). Suspending and resuming a warehouse may clear cache, but it does not increase available memory and does not solve memory spilling.
E). Clustering can improve pruning and reduce scanned data for some queries, but it is not the direct general solution for queries that are spilling because they are too large for memory.
Official Snowflake documentation reference:
Snowflake Query Profile documentation explains that spilling to local or remote storage can occur when operations do not fit in memory. Snowflake performance guidance recommends scaling up the warehouse or rewriting queries to reduce the amount of data processed.
