Snowflake SnowPro Advanced Administrator ADA-C02 認定 ADA-C02 試験問題 (Q40-Q45):

質問 # 40
What Snowflake capabilities are commonly used in rollback scenarios? (Choose two.)

A. ALTER TABLE prd_table SWAP WITH prd_table_bkp;
B. Contact Snowflake Support to retrieve Fail-safe data.
C. SELECT SYSTEM$CANCEL_QUERY('problematic_query_id');
D. CREATE TABLE prd_table_bkp CLONE prd_table BEFORE (STATEMENT => 'problematic_query_id');
E. CREATE TABLE prd_table_bkp as SELECT * from table(result_scan('problematic_query_id'));

正解：A、D

解説：
Creating a clone of a table at a point in time before a problematic statement uses Snowflake Time Travel to restore the table’s previous state without copying data. This allows recovery of the table as it existed before the issue occurred.
Swapping tables enables a fast rollback by exchanging the original production table with the restored backup table. This operation is metadata-only and allows immediate restoration of the previous version of the data with minimal downtime.

質問 # 41
What are the MINIMUM grants required on the database, schema, and table for a stream to be properly created and managed?

A. Database: Usage
Schema: Usage
Table: Select
B. Database: Usage
Schema: Usage, Create Stream
Table: Select
C. Database: Usage
Schema: Usage
Table: Select, Create Stream
D. Database: Usage, Create Stream
Schema: Usage
Table: Select

正解：B

解説：
Database: USAGE is required to access the database.
Schema: USAGE and CREATE STREAM are required to create streams in the schema.
Table: SELECT is needed so the stream can track changes on the table.

質問 # 42
What are the requirements when creating a new account within an organization in Snowflake? (Choose two.)

A. The account name must be specified when the account is created.
B. The account name must be unique among all Snowflake customers.
C. The account name is immutable and cannot be changed.
D. The account requires at least one ORGADMIN role within one of the organization's accounts.
E. The account name must be unique within the organization.

正解：A、E

解説：
When creating a new account within a Snowflake organization, the account name must be specified at creation and it must be unique within the organization. It does not need to be unique across all Snowflake customers, only within that specific organization.

質問 # 43
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, secure views, and materialized views
B. There are no object references that need to be re-pointed
C. Sequences, storage integrations, views, secure views, and materialized views
D. Sequences, views, and secure views

正解：B

解説：
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.

質問 # 44
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 sample system (20);
D. select * from LINEITEM tablesample system (20) seed (1);

正解：C

解説：
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.
