Snowflake SnowPro Advanced Architect Certification 認定 ARA-C01 試験問題 (Q102-Q107):

質問 # 102
USERADMIN and Security administrators (i.e. users with the SECURITYADMIN role) or higher can create roles.

A. FALSE
B. TRUE

正解：B

質問 # 103
Which command will create a schema without Fail-safe and will restrict object owners from passing on access to other users?

A. create TRANSIENT schema EDW.ACCOUNTING WITH MANAGED ACCESS
DATA_RETENTION_TIME_IN_DAYS = 7;
B. create schema EDW.ACCOUNTING WITH MANAGED ACCESS
DATA_RETENTION_TIME_IN_DAYS - 7;
C. create TRANSIENT schema EDW.ACCOUNTING WITH MANAGED ACCESS
DATA_RETENTION_TIME_IN_DAYS = 1;
D. create schema EDW.ACCOUNTING WITH MANAGED ACCESS;

正解：A

解説：
A transient schema in Snowflake is designed without a Fail-safe period, meaning it does not incur additional storage costs once it leaves Time Travel, and it is not protected by Fail-safe in the event of a data loss. The WITH MANAGED ACCESS option ensures that all privilege grants, including future grants on objects within the schema, are managed by the schema owner, thus restricting object owners from passing on access to other users1.

質問 # 104
Is it possible for a data provider account with a Snowflake Business Critical edition to share data with an Enterprise edition data consumer account?

A. If a user in the provider account with role authority to create or alter share adds an Enterprise account as a consumer, it can import the share.
B. A Business Critical account cannot be a data sharing provider to an Enterprise consumer. Any consumer accounts must also be Business Critical.
C. If a user in the provider account with a share owning role which also has override share restrictions privilege share_restrictions set to False when adding an Enterprise consumer account, it can import the share.
D. If a user in the provider account with a share owning role sets share_restrictions to False when adding an Enterprise consumer account, it can import the share.

正解：C

解説：
* Data sharing is a feature that allows Snowflake accounts to share data with each other without the need for data movement or copying1. Data sharing is enabled by creating shares, which are collections of database objects (tables, views, secure views, and secure UDFs) that can be accessed by other accounts, called consumers2.
* By default, Snowflake does not allow sharing data from a Business Critical edition account to a non-Business Critical edition account. This is because Business Critical edition offers higher levels of data protection and encryption than other editions, and sharing data with lower editions may compromise the security and compliance of the data3.
* However, Snowflake provides the OVERRIDE SHARE RESTRICTIONS global privilege, which allows a user to override the default restriction and share data from a Business Critical edition account to a non-Business Critical edition account. This privilege is granted to the ACCOUNTADMIN role by default, and can be granted to other roles as well4.
* To enable data sharing from a Business Critical edition account to an Enterprise edition account, the following steps are required34:
* A user in the provider account with the OVERRIDE SHARE RESTRICTIONS privilege must create or alter a share and add the Enterprise edition account as a consumer. The user must also set the share_restrictions parameter to False when adding the consumer. This parameter indicates whether the share is restricted to Business Critical edition accounts only. Setting it to False allows the share to be imported by lower edition accounts.
* A user in the consumer account with the IMPORT SHARE privilege must import the share and grant access to the share objects to other roles in the account. The user must also set the share_restrictions parameter to False when importing the share. This parameter indicates whether the consumer account accepts shares from Business Critical edition accounts only. Setting it to False allows the consumer account to import shares from lower edition accounts.

質問 # 105
What is the recommended strategy to choose the right sized warehouse to achieve best performance based on query processing?

A. Run homogenous queries on the same warehouse
B. Run heterogenous queries on the same warehouse

正解：A

質問 # 106
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 $tb1_ref WHERE $col_ref IN ($var1, Svar2, Svar3);
B. Select * FROM Stbl_ref WHERE Scol_ref IN ('Name1','Nam2','Name3');
C. SELECT * FROM EMP_TBL WHERE identifier(Scol_ref) IN ('Namel','Name2', 'Name3');
D. SELECT * FROM identifier($tbl_ref) WHERE ID IN Cvarl','var2','var3');
E. SELECT * FROM identifier<Stbl_ref> WHERE NAME IN ($var1, $var2, $var3);

正解：A、C

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:
