Snowflake SnowPro Advanced Administrator ADA-C02 認定 ADA-C02 試験問題 (Q46-Q51):

質問 # 46
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 # 47
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
max_cluster_count = 10
scaling_policy = standard
auto_suspend = 600
auto_resume = false;
B. create or replace warehouse reporting_wh
warehouse_size = xxxlarge
auto_suspend = 60
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 = medium
auto_suspend = 600
auto_resume = true;

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 # 48
DatabaseA has a single schema called Schema1. This schema contains many tables and views. The ANALYST role has privileges to select from all objects in DatabaseA.Schema1. The SYSADMIN role clones DatabaseA to DatabaseA_clone.
What privileges does the ANALYST role have on tables and views in DatabaseA_clone? (Choose two.)

A. SELECT on all tables, and only secure views in DatabaseA_clone.Schema1
B. SELECT on all tables, and only non-secure views in DatabaseA_clone.Schema1
C. USAGE on the database DatabaseA_clone.Schema1
D. USAGE on the schema DatabaseA_clone
E. SELECT on all tables and views in DatabaseA_clone.Schema1

正解：D、E

解説：
When a database is cloned, the privileges granted on objects within the source database are preserved in the cloned database. Roles that had privileges on objects such as tables and views continue to have those privileges on the corresponding cloned objects. Therefore, the ANALYST role retains SELECT privileges on all tables and views within the cloned schema.
In addition, the cloned database and schema inherit the same access control configuration, allowing the role to use the schema within the cloned database.

質問 # 49
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. Wrap the query in a User-Defined Function (UDF) to match syntax execution.
C. Leverage the CURRENT_DATE function for date calculations.
D. Assign everyone on the sales team to the same security role.

正解：C

解説：
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.

質問 # 50
An Administrator has a user who needs to be able to suspend and resume a task based on the current virtual warehouse load, but this user should not be able to modify the task or start a new run.
What privileges should be granted to the user to meet these requirements? (Choose two.)

A. OWNERSHIP on the task
B. OPERATE on the task
C. OWNERSHIP on the database and schema containing the task
D. EXECUTE TASK on the task
E. USAGE on the database and schema containing the task

正解：B、E

解説：
To suspend and resume a task, the user needs the OPERATE privilege on the task. Additionally, USAGE on the database and schema containing the task is required to access it. Granting these together allows control of task state without giving modification or ownership rights.
