質問 # 1034
What persistent data structures are used by the search optimization service to improve the performance of point lookups?
正解：C
解説：
The search optimization service in Snowflake uses persistent data structures known as search access paths to improve the performance of point lookups. These structures enable efficient retrieval of data by reducing the amount of data scanned during queries.
Search Access Paths:
Search access paths are special indexing structures maintained by the search optimization service.
They store metadata about the distribution of data within tables, enabling faster lookups for specific values.
Point Lookups:
Point lookups involve searching for a specific value within a column.
By leveraging search access paths, Snowflake can quickly locate the exact micro-partition containing the value, minimizing the amount of data scanned.
Performance Improvement:
The use of search access paths significantly reduces query execution time for point lookups.
This is especially beneficial for large tables where scanning all micro-partitions would be computationally expensive.

質問 # 1037
What information is stored in the ACCESS_HlSTORY view?
正解：A
解説：
Details around the privileges that have been granted for all objects in an account. The ACCESS_HISTORY view in Snowflake provides a comprehensive log of access control changes, including grants and revocations of privileges on all securable objects within the account. This information is crucial for auditing and monitoring the security posture of your Snowflake environment.
Here's how to understand and use the ACCESS_HISTORY view:
Purpose of ACCESS_HISTORY View: It is designed to track changes in access controls, such as when a user or role is granted or revoked privileges on various Snowflake objects. This includes tables, schemas, databases, and more.
Querying ACCESS_HISTORY: To access this view, you can use the following SQL query pattern:
SELECT * FROM SNOWFLAKE.ACCOUNT_USAGE.ACCESS_HISTORY WHERE EVENT_TYPE = 'GRANT' OR EVENT_TYPE = 'REVOKE'; Interpreting the Results: The results from the ACCESS_HISTORY view include the object type, the specific privilege granted or revoked, the grantee (who received or lost the privilege), and the timestamp of the event. This data is invaluable for audits and compliance checks.
質問 # 1038
What happens to the objects in a reader account when the DROP MANAGED ACCOUNT command is executed?
正解：D
解説：
When the DROP MANAGED ACCOUNT command is executed in Snowflake, it removes the managed account, including all objects created within the account, and access to the account is immediately restricted2.
