Snowflake SnowPro Advanced Administrator ADA-C02 認定 ADA-C02 試験問題 (Q60-Q65):

質問 # 60
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(1)));
B. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(),
OBJECT_CONSTRUCT(*)
FROM TABLE(RESULT_SCAN(LAST_QUERY_ID()));
C. SHOW WAREHOUSES;
INSERT INTO VWH_META
SELECT CURRENT_TIMESTAMP(), *
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：B

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 # 61
What are characteristics of data replication in Snowflake? (Choose three.)

A. To start replication run the ALTER DATABASE ... REFRESH command on the account where the secondary database resides.
B. Users must be granted REPLICATIONADMIN privileges in order to enable replication.
C. Replication can only occur within the same cloud provider.
D. Databases created from shares can be replicated.
E. Users can have unlimited primary databases and they can be replicated to an unlimited number of accounts if all accounts are within the same organization.
F. The ALTER DATABASE ... ENABLE REPLICATION TO ACCOUNTS command must be issued from the primary account.

正解：A、D、F

解説：
Replication must be enabled on the primary account using ALTER DATABASE ... ENABLE REPLICATION TO ACCOUNTS.
To refresh replicated data, ALTER DATABASE ... REFRESH is executed on the secondary database.
Databases created from shares can also be replicated.

質問 # 62
An Administrator has been asked to support the company's application team need to build a loyalty program for its customers. The customer table contains Personal Identifiable Information (PII), and the application team's role is DEVELOPER.
CREATE TABLE customer_data (
customer_first_name string,
customer_last_name string,
customer_address string,
customer_email string,
... some other columns,
);
The application team would like to access the customer data, but the email field must be obfuscated.
How can the Administrator protect the sensitive information, while maintaining the usability of the data?

A. Use the CURRENT_ROLE and CURRENT_USER context functions to integrate with a secure view and filter the sensitive data.
B. Use the CURRENT_ROLE context function to integrate with a masking policy on the fields that contain sensitive data.
C. Create a view on the customer_data table to eliminate the email column by omitting it from the SELECT clause. Grant the role DEVELOPER access to the view.
D. Create a separate table for all the non-PII columns and grant the role DEVELOPER access to the new table.

正解：B

解説：
The correct approach is to apply a dynamic data masking policy on the sensitive customer_email column. Using the CURRENT_ROLE context function in the masking policy allows the Administrator to obfuscate the email for the DEVELOPER role while maintaining usability of the data for other authorized roles.

質問 # 63
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. No, because 3.3.3.10 is found in the BLOCKED_IP_LIST of bar_policy.
B. No, because 3.3.3.10 is not found in the ALLOWED_IP_LIST of foo_policy.
C. Yes, because 3.3.3.10 is found in the ALLOWED_IP_LIST of bar_policy.
D. Yes, because 3.3.3.10 is found in the ALLOWED_IP_LIST of foo_policy.

正解：A

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 # 64
What information is required from the Identity Provider (IdP) to enable federated authentication in Snowflake? (Choose two.)

A. IdP account details
B. Authentication certificate
C. URL endpoint for SAML requests
D. IdP encryption key
E. SAML response format

正解：B、C

解説：
Federated authentication in Snowflake using SAML requires the Identity Provider's SAML endpoint URL so Snowflake can send authentication requests to the IdP during the login process.
Snowflake also requires the IdP's signing certificate to validate the authenticity and integrity of the SAML assertions returned by the Identity Provider during authentication.
