Snowflake SnowPro Advanced Administrator ADA-C02 ADA-C02 Prüfungsfragen mit Lösungen (Q41-Q46):

41. Frage
DatabaseA has a single schema called Schema1. This schema contains many tables and views. The ANALYST role has privileges to select from all objects in DatabaseA.Schema1. The SYSADMIN role clones DatabaseA to DatabaseA_clone.
What privileges does the ANALYST role have on tables and views in DatabaseA_clone? (Choose two.)

A. USAGE on the schema DatabaseA_clone
B. SELECT on all tables and views in DatabaseA_clone.Schema1
C. USAGE on the database DatabaseA_clone.Schema1
D. SELECT on all tables, and only secure views in DatabaseA_clone.Schema1
E. SELECT on all tables, and only non-secure views in DatabaseA_clone.Schema1

Antwort: A,B

Begründung:
When a database is cloned, the privileges granted on objects within the source database are preserved in the cloned database. Roles that had privileges on objects such as tables and views continue to have those privileges on the corresponding cloned objects. Therefore, the ANALYST role retains SELECT privileges on all tables and views within the cloned schema.
In addition, the cloned database and schema inherit the same access control configuration, allowing the role to use the schema within the cloned database.

42. Frage
An Administrator needs to create a sample of the table LINEITEM. The sample should not be repeatable and the sampling function should take the data by blocks of rows.
What select command will generate a sample of 20% of the table?

A. select * from LINEITEM tablesample block (20 rows);
B. select * from LINEITEM tablesample system (20) seed (1);
C. select * from LINEITEM sample system (20);
D. select * from LINEITEM sample bernoulli (20);

Antwort: C

Begründung:
SYSTEM sampling performs block sampling, meaning Snowflake selects entire blocks of rows rather than evaluating each row individually. This satisfies the requirement that the sampling function take data by blocks of rows. Using SYSTEM (20) returns approximately 20% of the table and, since no seed value is specified, the result is not repeatable.

43. Frage
A team is provisioning new lower environments from the production database using cloning. All production objects and references reside in the database, and do not have external references.
What set of object references needs to be re-pointed before granting access for usage?

A. Sequences, storage integrations, views, secure views, and materialized views
B. Sequences, views, secure views, and materialized views
C. There are no object references that need to be re-pointed
D. Sequences, views, and secure views

Antwort: C

Begründung:
When cloning a database in Snowflake, all objects - including sequences, views, secure views, and materialized views - are fully contained within the cloned database. Since there are no external references, no object references need to be re-pointed before granting access.

44. Frage
An Administrator has been asked to support the company's application team need to build a loyalty program for its customers. The customer table contains Personal Identifiable Information (PII), and the application team's role is DEVELOPER.
CREATE TABLE customer_data (
customer_first_name string,
customer_last_name string,
customer_address string,
customer_email string,
... some other columns,
);
The application team would like to access the customer data, but the email field must be obfuscated.
How can the Administrator protect the sensitive information, while maintaining the usability of the data?

A. Use the CURRENT_ROLE and CURRENT_USER context functions to integrate with a secure view and filter the sensitive data.
B. Use the CURRENT_ROLE context function to integrate with a masking policy on the fields that contain sensitive data.
C. Create a view on the customer_data table to eliminate the email column by omitting it from the SELECT clause. Grant the role DEVELOPER access to the view.
D. Create a separate table for all the non-PII columns and grant the role DEVELOPER access to the new table.

Antwort: B

Begründung:
The correct approach is to apply a dynamic data masking policy on the sensitive customer_email column. Using the CURRENT_ROLE context function in the masking policy allows the Administrator to obfuscate the email for the DEVELOPER role while maintaining usability of the data for other authorized roles.

45. Frage
The following SQL command was executed:
Use role SECURITYADMIN;
Grant ownership
On future tables
In schema PROD.WORKING
To role PROD_WORKING_OWNER;
Grant role PROD_WORKING_OWNER to role SYSADMIN;
Use role ACCOUNTADMIN;
Create table PROD.WORKING.XYZ (value number);
Which role(s) can alter or drop table XYZ?

A. SECURITYADMIN, SYSADMIN, and ACCOUNTADMIN can alter or drop table XYZ.
B. PROD_WORKING_OWNER, ACCOUNTADMIN, and SYSADMIN can alter or drop table XYZ.
C. Because ACCOUNTADMIN created the table, only the ACCOUNTADMIN role can alter or drop table XYZ.
D. Only the PROD_WORKING_OWNER role can alter or drop table XYZ.

Antwort: B

Begründung:
Although ACCOUNTADMIN created the table, the future ownership grant ensures ownership of new tables in PROD.WORKING is assigned to PROD_WORKING_OWNER. Since PROD_WORKING_OWNER was granted to SYSADMIN, both roles, along with ACCOUNTADMIN (which always has ultimate rights), can alter or drop the table XYZ.
