質問 1:
A company has implemented Snowflake replication between two Snowflake accounts, both of which are running on a Snowflake Enterprise edition.

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

質問 4:
A retailer uses a TRANSACTIONS table (100M rows, 1.2 TB) that has been clustered by the STORE_ID column (varchar(50)). The vast majority of analyses on this table are grouped by STORE_ID to look at store performance.
There are 1000 stores operated by the retailer but most sales come from only 20 stores. The Administrator notes that most queries are currently experiencing poor pruning, with large amounts of bytes processed by even simple queries.
Why is this occurring?
A. Sales across stores are not uniformly distributed.
B. The table is not big enough to take advantage of the clustering key.
C. The cardinality of the stores to transaction count ratio is too low to use the STORE_ID as a clustering key.
D. The STORE_ID should be numeric.
正解:A

質問 5:
A team of developers created a new schema for a new project. The developers are assigned the role DEV_TEAM which was set up using the following statements:
USE ROLE SECURITYADMIN;
CREATE ROLE DEV_TEAM;
GRANT USAGE, CREATE SCHEMA ON DATABASE DEV_DB01 TO ROLE DEV_TEAM;
GRANT USAGE ON WAREHOUSE DEV_WH TO ROLE DEV_TEAM;
Each team member's access is set up using the following statements:
USE ROLE SECURITYADMIN;
CREATE ROLE JDOE_PROFILE;
CREATE USER JDOE LOGIN_NAME = 'JDOE' DEFAULT ROLE='JDOE_PROFILE';
GRANT ROLE JDOE_PROFILE TO USER JDOE;
GRANT ROLE DEV_TEAM TO ROLE JDOE_PROFILE;
New tables created by any of the developers are not accessible by the team as a whole.
How can an Administrator address this problem?
A. Set up future grants on the newly-created schemas.
B. Assign usage privilege on the virtual warehouse DEV_WH to the role JDOE_PROFILE.
C. Set up the new schema as a managed-access schema.
D. Assign ownership privilege to DEV_TEAM on the newly-created schema.

質問 6:
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.
正解:B

質問 7:
When does auto-suspend occur for a multi-cluster virtual warehouse?
A. When the minimum number of clusters is running and there is no activity for the specified period of time.
B. Auto-suspend does not apply for multi-cluster warehouses.
C. When there has been no activity on any cluster for the specified period of time.
D. After a specified period of time when an additional cluster has started on the maximum number of clusters specified for a warehouse.
正解:A
