질문 # 22
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. Assign everyone on the sales team to the same virtual warehouse.
B. Leverage the CURRENT_DATE function for date calculations.
C. Assign everyone on the sales team to the same security role.
D. Wrap the query in a User-Defined Function (UDF) to match syntax execution.

정답：B

설명：
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.

질문 # 23
Which actions are considered breaking changes to data that is shared with consumers in the Snowflake Marketplace? (Choose two.)

A. Renaming a table
B. Unpublishing the data listing
C. Deleting data from a table
D. Adding region availability to the listing
E. Dropping a column from a table

정답：A,E

설명：
Dropping a column from a table or renaming a table breaks the shared schema and can cause dependent queries to fail for consumers. These are considered breaking changes to shared data in the Snowflake Marketplace.

질문 # 24
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 block (20 rows);
C. select * from LINEITEM tablesample system (20) seed (1);
D. select * from LINEITEM sample bernoulli (20);

정답：A

설명：
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.

질문 # 25
A Snowflake customer is experiencing higher costs than anticipated while migrating their data warehouse workloads from on-premises to Snowflake. The migration workloads have been deployed on a single warehouse and are characterized by a large number of small INSERTS rather than bulk loading of large extracts. That single warehouse has been configured as a single cluster, 2XL because there are many parallel INSERTS that are scheduled during nightly loads.
How can the Administrator reduce the costs, while minimizing the overall load times, for migrating data warehouse history?

A. The 2XL warehouse should be changed to 4XL to increase the number of threads available for parallel load queries.
B. The warehouse should be kept as a SMALL or XSMALL and configured as a multi-cluster warehouse to handle the parallel load queries.
C. The INSERTS should be converted to several tables to avoid contention on large tables that slows down query processing.
D. There should be another 2XL warehouse deployed to handle a portion of the load queries.

정답：B

설명：
For many small, parallel INSERTS, using a multi-cluster warehouse with smaller size (SMALL or XSMALL) allows more concurrent queries to run efficiently and reduces costs compared to a single large warehouse. This configuration improves concurrency without unnecessary compute expense.

질문 # 26
A company has implemented Snowflake replication between two Snowflake accounts, both of which are running on a Snowflake Enterprise edition. The replication is for the database APP_DB containing only one schema, APP_SCHEMA. The company's time Travel retention policy is currently set for 30 days for both accounts. An Administrator has been asked to extend the time Travel retention policy to 60 days on the secondary database only.
How can this requirement be met?

A. Set the data retention policy on the schemas in the secondary database to 60 days.
B. Set the data retention policy on the primary database to 60 days.
C. Set the data retention policy on the secondary database to 60 days.
D. Set the data retention policy on the primary database to 30 days and the schemas to 60 days.

정답：B

설명：
In Snowflake replication, Time Travel retention is determined by the primary database and is replicated to the secondary. The secondary cannot have a longer retention than the primary. To extend retention to 60 days on the secondary, the primary database’s retention must be increased to 60 days.
