Snowflake SnowPro Advanced Administrator ADA-C02 認定 ADA-C02 試験問題 (Q34-Q39):

質問 # 34
A Snowflake Administrator needs to persist all virtual warehouse configurations for auditing and backups. Given a table already exists with the following schema:
Table Name: VWH_META
Column 1: SNAPSHOT_TIME TIMESTAMP_NTZ
Column 2: CONFIG VARIANT
Which commands should be executed to persist the warehouse data at the time of execution in JSON format in the table VWH_META?

A. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(), *
FROM TABLE(RESULT_SCAN(LAST_QUERY_ID()));
B. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(),
FROM TABLE(RESULT_SCAN(LAST_QUERY_ID(1)));
C. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(),
OBJECT_CONSTRUCT(*)
FROM TABLE(RESULT_SCAN(LAST_QUERY_ID()));
D. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(), *
FROM TABLE(RESULT_SCAN(SELECT LAST_QUERY_ID(-1)));

正解：C

解説：
To persist warehouse configurations in JSON format, the result set from SHOW WAREHOUSES must be captured and converted into a variant object. Using OBJECT_CONSTRUCT(*) with RESULT_SCAN(LAST_QUERY_ID()) stores the full warehouse configuration snapshot as JSON in the CONFIG VARIANT column, along with the timestamp.

質問 # 35
Which type of listing in the Snowflake Marketplace can be added and queried immediately?

A. Monetized listing
B. Standard listing
C. Regional listing
D. Personalized listing

正解：B

解説：
A standard listing in the Snowflake Marketplace can be immediately added to an account and queried without requiring provider approval or additional setup.

質問 # 36
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 ownership privilege to DEV_TEAM on the newly-created schema.
C. Assign usage privilege on the virtual warehouse DEV_WH to the role JDOE_PROFILE.
D. Set up the new schema as a managed-access schema.

正解：A

解説：
Future grants allow privileges to be automatically granted on objects created in the future within a schema. By configuring future grants on the schema, privileges such as SELECT can automatically be granted to the DEV_TEAM role whenever new tables are created. This ensures that all developers using the DEV_TEAM role can access newly created tables without requiring manual privilege grants after each table creation.

質問 # 37
An Administrator needs to configure a virtual warehouse in Snowflake for a new use case with these details:
1. There will be 50-100 concurrent users running reports
2. Minimize costs based on the number of active users at a given time
3. The virtual warehouse should suspend and resume automatically based on user activity
Which configuration will meet these requirements?

A. create or replace warehouse reporting_wh
warehouse_size = xxxlarge
auto_suspend = 60
auto_resume = true;
B. create or replace warehouse reporting_wh
warehouse_size = medium
auto_suspend = 600
auto_resume = true;
C. create or replace warehouse reporting_wh
warehouse_size = medium
max_cluster_count = 10
scaling_policy = standard
auto_suspend = 600
auto_resume = true;
D. create or replace warehouse reporting_wh
warehouse_size = xxxlarge
max_cluster_count = 10
scaling_policy = standard
auto_suspend = 600
auto_resume = false;

正解：C

解説：
Supporting 50-100 concurrent users requires a multi-cluster warehouse so compute resources can scale to handle high concurrency. Setting a maximum cluster count allows Snowflake to automatically add clusters when query demand increases and reduce them when demand drops, which helps minimize cost based on active users. Enabling auto_suspend and auto_resume ensures the warehouse automatically stops when idle and restarts when queries arrive, further optimizing cost and operational efficiency.

質問 # 38
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 frequency of changes to the primary database as a result of data loading or DML operations
E. The amount of table data in the primary database that changes as a result of data loading or DML operations

正解：A、E

解説：
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.
