NEW QUESTION # 263
Which privilege is required to use the search optimization service in Snowflake?
Answer: C
Explanation:
To utilize the search optimization service in Snowflake, the correct syntax for granting privileges to a role involves specific commands that include adding search optimization capabilities:
Option C: GRANT ADD SEARCH OPTIMIZATION ON SCHEMA <schema_name> TO ROLE <role>. This command grants the specified role the ability to implement search optimization at the schema level, which is essential for enhancing search capabilities within that schema.
Options A and B do not include the correct verb "ADD," which is necessary for this specific type of grant command in Snowflake. Option D incorrectly mentions the database level, as search optimization privileges are typically configured at the schema level, not the database level.References: Snowflake documentation on the use of GRANT statements for configuring search optimization.
NEW QUESTION # 264
What command is used to unload data from a Snowflake table to a local file system?
Answer: C
Explanation:
The GET command is used to download (i.e., unload) files from a Snowflake internal stage to the local file system . COPY INTO writes to stages, not directly to local disk.
Reference:
Snowflake Docs: GET Command
NEW QUESTION # 265
Which table type stores a catalog of staged files in cloud storage?
Answer: D
Explanation:
The correct answer is B. Directory table .
A directory table is not a regular user-created table like a permanent, transient, or temporary table. It is an implicit object associated with a stage. It stores file-level metadata about staged files in cloud storage.
Directory tables are useful when users need to query information about files stored in a stage, such as file names, sizes, last modified timestamps, and relative paths.
Why B is correct:
A directory table stores a catalog of staged files in cloud storage. It allows users to query metadata about files in a stage using SQL.
Example concept:
SELECT *
FROM DIRECTORY(@my_stage);
This returns metadata about files stored in the stage.
Why the other options are incorrect:
A). Transient table stores user data but does not store a catalog of staged files.
C). Temporary table stores session-specific user data and disappears at the end of the session.
D). Permanent table stores persistent user data and supports Fail-safe, but it is not specifically used to catalog staged files.
Official Snowflake documentation reference:
Snowflake documentation describes directory tables as objects that store a catalog of staged files in cloud storage. Directory tables are associated with stages and can be queried to retrieve file metadata.
Reference: Snowflake Documentation - Directory tables; Snowflake Documentation - Stages; SnowPro Core Study Guide - Data Loading and Unloading.
NEW QUESTION # 266
Which SQL command can be used to see the CREATE definition of a masking policy?
Answer: A
Explanation:
The SQL command GET_DDL can be used to retrieve the CREATE definition of a masking policy in Snowflake.This command generates the DDL statement required to recreate the masking policy
NEW QUESTION # 267
Which queries can execute eligible portions in parallel by using the Query Acceleration Service? (Choose two.)
Answer: C,E
Explanation:
The Query Acceleration Service uses serverless compute resources to execute eligible portions of a query plan in parallel with the virtual warehouse. Snowflake identifies two primary eligible patterns:
large scans containing an aggregation or highly selective filter, and large scans that insert or copy many new rows. These patterns correspond directly to options B and E. Query acceleration is most useful for outlier queries with substantial scan work, unpredictable data volumes, or selective processing that can be divided across additional compute resources. Small scans generally do not contain enough parallelizable work to benefit. Complex joins on small tables are also not the primary eligibility pattern. Eligibility is determined at the query-plan level, so enabling the service does not guarantee that every submitted query will use it.
