Snowflake SnowPro Advanced Administrator ADA-C02 Sample Questions (Q55-Q60):

NEW QUESTION # 55
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 sample system (20);
B. select * from LINEITEM tablesample system (20) seed (1);
C. select * from LINEITEM tablesample block (20 rows);
D. select * from LINEITEM sample bernoulli (20);

Answer: A

Explanation:
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.

NEW QUESTION # 56
What steps are required to set up OKTAAPI token integration in Snowflake?

A. create or replace security integration okta_provisioning
type = scim
scim_client = 'okta'
run_as_role = 'OKTA PROVISIONER';
Update this step every 6 months.
B. grant role okta_provisioner to role ACCOUNTADMIN;
create or replace security integration okta_provisioning
type = scim
scim_client = 'okta'
run_as_role = 'OKTA PROVISIONER';
Update these steps every 12 months.
C. use role ACCOUNTADMIN;
select system$ generate_scim_access_token ('OKTA PROVISIONING');
Update these steps every 6 months.
D. use role ACCOUNTADMIN;
select system$ generate_scim_access_token ('OKTA PROVISIONING');
Update these steps every 12 months.

Answer: C

Explanation:
Use the ACCOUNTADMIN role to generate the SCIM access token for Okta with system$generate_scim_access_token.
The access token must be regenerated and updated in Okta every 6 months for continued integration.

NEW QUESTION # 57
The following commands were executed:
Grant usage on database PROD to role PROD_ANALYST;
Grant usage on database PROD to role PROD_SUPERVISOR;
Grant ALL PRIVILEGES on schema PROD.WORKING to role PROD_ANALYST;
Grant ALL PRIVILEGES on schema PROD.WORKING to role PROD_SUPERVISOR;
Grant role PROD_ANALYST to user A;
Grant role PROD_SUPERVISOR to user B;
What authority does each user have on the WORKING schema?

A. Only user B can create tables, because all privileges were transferred to PROD_SUPERVISOR.
B. Tables created by either user A or user B will be visible to both users.
C. All existing tables in schema PROD.WORKING will be visible to both users.
D. Both user A and user B can create tables in the PROD.WORKING schema.

Answer: D

Explanation:
Granting ALL PRIVILEGES on the schema PROD.WORKING to both roles (PROD_ANALYST and PROD_SUPERVISOR) gives each user (A and B) full schema-level rights, including the ability to create tables. Since both roles received these grants independently, both users can create tables in the schema.

NEW QUESTION # 58
What role or roles should be used to properly create the object required to setup OAuth 2.0 integration?

A. Any role with GRANT USAGE on SECURITY INTEGRATION
B. ACCOUNTADMIN only
C. ACCOUNTADMIN and SYSADMIN
D. ACCOUNTADMIN and SECURITYADMIN

Answer: D

Explanation:
Creating an OAuth 2.0 security integration requires elevated security privileges. Snowflake requires either the ACCOUNTADMIN role or the SECURITYADMIN role to properly create and manage the security integration object.

F. SELECT * FROM my_table AT(TIMESTAMP => '2021-01-01 07:00:00'::timestamp);

Answer: B,D,F
