Snowflake SnowPro Advanced Administrator ADA-C02 認定 ADA-C02 試験問題 (Q29-Q34):

質問 # 29
A user with the proper role issues the following commands when setting up and activating network policies:
CREATE OR REPLACE NETWORK POLICY foo_policy
ALLOWED_IP_LIST = ('1.1.1.0/24', '2.2.2.0/24', '3.3.3.0/24')
BLOCKED_IP_LIST = ('1.1.1.1')
COMMENT = 'Account level policy';
ALTER ACCOUNT SET NETWORK_POLICY=foo_policy;
CREATE OR REPLACE NETWORK POLICY bar_policy
ALLOWED_IP_LIST = ('3.3.3.0/24')
BLOCKED_IP_LIST = ('3.3.3.10')
COMMENT = 'user level policy';
ALTER USER user1 SET NETWORK_POLICY=BAR_POLICY;
Afterwards, user1 attempts to log in to Snowflake from IP address 3.3.3.10.
Will the login be successful?

A. Yes, because 3.3.3.10 is found in the ALLOWED_IP_LIST of foo_policy.
B. No, because 3.3.3.10 is found in the BLOCKED_IP_LIST of bar_policy.
C. Yes, because 3.3.3.10 is found in the ALLOWED_IP_LIST of bar_policy.
D. No, because 3.3.3.10 is not found in the ALLOWED_IP_LIST of foo_policy.

正解：B

解説：
Although 3.3.3.10 is in the ALLOWED_IP_LIST, it is also explicitly listed in the BLOCKED_IP_LIST of the user-level policy (bar_policy). Blocked IPs always take precedence over allowed IPs in Snowflake network policies, so the login attempt will fail.

質問 # 30
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(),
OBJECT_CONSTRUCT(*)
FROM TABLE(RESULT_SCAN(LAST_QUERY_ID()));
B. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(), *
FROM TABLE(RESULT_SCAN(SELECT LAST_QUERY_ID(-1)));
C. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(),
FROM TABLE(RESULT_SCAN(LAST_QUERY_ID(1)));
D. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(), *
FROM TABLE(RESULT_SCAN(LAST_QUERY_ID()));

正解：A

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 # 31
A user has enrolled in Multi-factor Authentication (MFA) for connecting to Snowflake. The user informs the Snowflake Administrator that they lost their mobile phone the previous evening.
Which step should the Administrator take to allow the user to log in to the system, without revoking their MFA enrollment?

A. Alter the user and set MINS_TO_BYPASS_MFA to a value that will disable MFA long enough for the user to log in.
B. Alter the user and set DISABLE_MFA to true, which will suspend the MFA requirement for 24 hours.
C. Instruct the user to append the normal URL with /?mode=mfa_bypass&code= to log on.
D. Instruct the user to connect to Snowflake using SnowSQL, which does not support MFA authentication.

正解：A

解説：
The correct step is to use ALTER USER ... SET MINS_TO_BYPASS_MFA = <minutes> which temporarily suspends MFA for the specified duration, allowing the user to log in and reconfigure their MFA without revoking enrollment. This preserves MFA setup and is the supported method in Snowflake.

質問 # 32
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. Leverage the CURRENT_DATE function for date calculations.
B. Assign everyone on the sales team to the same virtual warehouse.
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.

正解：A

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 # 33
A Snowflake Administrator needs to set up Time Travel for a presentation area that includes facts and dimensions tables, and receives a lot of meaningless and erroneous IoT data. Time Travel is being used as a component of the company's data quality process in which the ingestion pipeline should revert to a known quality data state if any anomalies are detected in the latest load. Data from the past 30 days may have to be retrieved because of latencies in the data acquisition process.
According to best practices, how should these requirements be met? (Choose two.)

A. Only TRANSIENT tables should be used to ensure referential integrity between the fact and dimension tables.
B. The fact and dimension tables should be cloned together using the same Time Travel options to reduce potential referential integrity issues with the restored data.
C. Related data should not be placed together in the same schema. Facts and dimension tables should each have their own schemas.
D. The fact and dimension tables should have the same DATA_RETENTION_TIME_IN_DAYS.
E. The DATA_RETENTION_TIME_IN_DAYS should be kept at the account level and never used for lower level containers (databases and schemas).

正解：B、D

解説：
To ensure consistent recovery, fact and dimension tables must have the same DATA_RETENTION_TIME_IN_DAYS, so they can be restored to the same point in time.
Cloning the fact and dimension tables together with consistent Time Travel options ensures data integrity and avoids referential mismatches when reverting to a prior state.
