Snowflake SnowPro Advanced Architect Certification 認定 ARA-C01 試験問題 (Q55-Q60):

質問 # 55
How is the change of local time due to daylight savings time handled in Snowflake tasks? (Choose two.)

A. A task scheduled in a UTC-based schedule will have no issues with the time changes.
B. Task schedules can be designed to follow specified or local time zones to accommodate the time changes.
C. A task schedule will follow only the specified time and will fail to handle lost or duplicated hours.
D. A task will move to a suspended state during the daylight savings time change.
E. A frequent task execution schedule like minutes may not cause a problem, but will affect the task history.

正解：A、B

解説：
According to the Snowflake documentation1 and the web search results2, these two statements are true about how the change of local time due to daylight savings time is handled in Snowflake tasks. A task is a feature that allows scheduling and executing SQL statements or stored procedures in Snowflake. A task can be scheduled using a cron expression that specifies the frequency and time zone of the task execution.
* A task scheduled in a UTC-based schedule will have no issues with the time changes. UTC is a universal time standard that does not observe daylight savings time. Therefore, a task that uses UTC as the time zone will run at the same time throughout the year, regardless of the local time changes1.
* Task schedules can be designed to follow specified or local time zones to accommodate the time changes. Snowflake supports using any valid IANA time zone identifier in the cron expression for a task. This allows the task to run according to the local time of the specified time zone, which may include daylight savings time adjustments. For example, a task that uses Europe/London as the time zone will run one hour earlier or later when the local time switches between GMT and BST12.

質問 # 56
What is a key consideration when setting up search optimization service for a table?

A. The table must be clustered with a key having multiple columns for effective search optimization.
B. Search optimization service can help to optimize storage usage by compressing the data into a GZIP format.
C. Search optimization service works best with a column that has a minimum of 100 K distinct values.
D. Search optimization service can significantly improve query performance on partitioned external tables.

正解：C

解説：
A: The Search Optimization Service is designed to accelerate the performance of queries that use filters on large tables. One of the key considerations for its effectiveness is using it with tables where the columns used in the filter conditions have a high number of distinct values, typically in the hundreds of thousands or more.
This is because the service creates a map-reduce-like index on the column to speed up queries that use point lookups or range scans on that column. The more unique values there are, the more effective the index is at narrowing down the search space.References: Snowflake documentation and best practices on the Search Optimization Service, which would be covered under the SnowPro Advanced: Architect certification materials.

質問 # 57
Data loading transformation as part of copying data to a table from stage supports selecting data from user stage and named stages(internal and external) only

A. FALSE
B. TRUE

正解：B

質問 # 58
At which object type level can the APPLY MASKING POLICY, APPLY ROW ACCESS POLICY and APPLY SESSION POLICY privileges be granted?

A. Database
B. Schema
C. Table
D. Global

正解：D

解説：
The object type level at which the APPLY MASKING POLICY, APPLY ROW ACCESS POLICY and APPLY SESSION POLICY privileges can be granted is global. These are account-level privileges that control who can apply or unset these policies on objects such as columns, tables, views, accounts, or users.
These privileges are granted to the ACCOUNTADMIN role by default, and can be granted to other roles as needed. The other options are incorrect because they are not the object type level at which these privileges can be granted. Database, schema, and table are lower-level object types that do not support these privileges. References: Access Control Privileges | Snowflake Documentation, Using Dynamic Data Masking

質問 # 59
A table, EMP_ TBL has three records as shown:

The following variables are set for the session:

Which SELECT statements will retrieve all three records? (Select TWO).

A. SELECT * FROM EMP_TBL WHERE identifier(Scol_ref) IN ('Namel','Name2', 'Name3');
B. Select * FROM Stbl_ref WHERE Scol_ref IN ('Name1','Nam2','Name3');
C. SELECT * FROM identifier($tbl_ref) WHERE ID IN Cvarl','var2','var3');
D. SELECT * FROM identifier<Stbl_ref> WHERE NAME IN ($var1, $var2, $var3);
E. SELECT * FROM $tb1_ref WHERE $col_ref IN ($var1, Svar2, Svar3);

正解：A、E

解説：
* The correct answer is B and E because they use the correct syntax and values for the identifier function and the session variables.
* The identifier function allows you to use a variable or expression as an identifier (such as a table name or column name) in a SQL statement. It takes a single argument and returns it as an identifier. For example, identifier($tbl_ref) returns EMP_TBL as an identifier.
* The session variables are set using the SET command and can be referenced using the $ sign. For example, $var1 returns Name1 as a value.
* Option A is incorrect because it uses Stbl_ref and Scol_ref, which are not valid session variables or identifiers. They should be $tbl_ref and $col_ref instead.
* Option C is incorrect because it uses identifier<Stbl_ref>, which is not a valid syntax for the identifier function. It should be identifier($tbl_ref) instead.
* Option D is incorrect because it uses Cvarl, var2, and var3, which are not valid session variables or values. They should be $var1, $var2, and $var3 instead. References:
* Snowflake Documentation: Identifier Function
* Snowflake Documentation: Session Variables
