Snowflake SnowPro Advanced Administrator ADA-C02 Sample Questions (Q20-Q25):

NEW QUESTION # 20
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, views, and secure views
B. Sequences, storage integrations, views, secure views, and materialized views
C. There are no object references that need to be re-pointed
D. Sequences, views, secure views, and materialized views

Answer: C

Explanation:
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.

NEW QUESTION # 21
An organization's sales team leverages this Snowflake query a few times a day:
SELECT CUSTOMER_ID, CUSTOMER_NAME, ADDRESS, PHONE_NO
FROM CUSTOMERS
WHERE LAST_UPDATED BETWEEN TO_DATE(CURRENT_TIMESTAMP) AND (TO_DATE(CURRENT_TIMESTAMP)-7);
What can the Snowflake Administrator do to optimize the use of persisted query results whenever possible?

A. Leverage the CURRENT_DATE function for date calculations.
B. Assign everyone on the sales team to the same security role.
C. Wrap the query in a User-Defined Function (UDF) to match syntax execution.
D. Assign everyone on the sales team to the same virtual warehouse.

Answer: A

Explanation:
Query result caching in Snowflake requires queries to be textually identical. Using CURRENT_TIMESTAMP causes queries to differ on each execution. By switching to CURRENT_DATE, the query becomes stable within a day, allowing Snowflake to reuse persisted results and improve performance.

NEW QUESTION # 22
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 bernoulli (20);
B. select * from LINEITEM tablesample block (20 rows);
C. select * from LINEITEM tablesample system (20) seed (1);
D. select * from LINEITEM sample system (20);

Answer: D

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 # 23
In general, the monthly billing for database replication is proportional to which variables? (Choose two.)

A. The frequency of the secondary database refreshes from the primary database
B. The number of times data moves across regions and/or cloud service providers between the primary and secondary database accounts
C. The number and size of warehouses defined in the primary account
D. The amount of table data in the primary database that changes as a result of data loading or DML operations
E. The frequency of changes to the primary database as a result of data loading or DML operations

Answer: A,D

Explanation:
Replication billing is proportional to the amount of table data in the primary database that changes and needs to be replicated.
The frequency of secondary database refreshes determines how often changed data is transferred, directly impacting replication costs.

NEW QUESTION # 24
What access control policy will be put into place when future grants are assigned to both database and schema objects?

A. Database, privileges will take precedence over schema privileges.
B. An access policy combining both the database object and the schema object will be used, with the most restrictive policy taking precedence.
C. An access policy combining both the database object and the schema object will be used, with the most permissive policy taking precedence.
D. Schema privileges will take precedence over database privileges.

Answer: D

Explanation:
When future grants are set at both the database and schema levels, schema-level future grants take precedence over database-level grants for objects created within that schema.
