Snowflake SnowPro Advanced Administrator ADA-C02 認定 ADA-C02 試験問題 (Q39-Q44):

質問 # 39
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 context function to integrate with a masking policy on the fields that contain sensitive data.
B. Create a separate table for all the non-PII columns and grant the role DEVELOPER access to the new table.
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. Use the CURRENT_ROLE and CURRENT_USER context functions to integrate with a secure view and filter the sensitive data.

正解：A

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 # 40
A Snowflake customer is experiencing higher costs than anticipated while migrating their data warehouse workloads from on-premises to Snowflake. The migration workloads have been deployed on a single warehouse and are characterized by a large number of small INSERTS rather than bulk loading of large extracts. That single warehouse has been configured as a single cluster, 2XL because there are many parallel INSERTS that are scheduled during nightly loads.
How can the Administrator reduce the costs, while minimizing the overall load times, for migrating data warehouse history?

A. The warehouse should be kept as a SMALL or XSMALL and configured as a multi-cluster warehouse to handle the parallel load queries.
B. The INSERTS should be converted to several tables to avoid contention on large tables that slows down query processing.
C. There should be another 2XL warehouse deployed to handle a portion of the load queries.
D. The 2XL warehouse should be changed to 4XL to increase the number of threads available for parallel load queries.

正解：A

解説：
For many small, parallel INSERTS, using a multi-cluster warehouse with smaller size (SMALL or XSMALL) allows more concurrent queries to run efficiently and reduces costs compared to a single large warehouse. This configuration improves concurrency without unnecessary compute expense.

質問 # 41
Which commands can be performed by a user with the ORGADMIN role but not the ACCOUNTADMIN role? (Choose two.)

A. SELECT SYSTEM$GLOBAL_ACCOUNT_SET_PARAMETER('ACCOUNT_LOCATOR','ENABLE_ACCOUNT_DATABASE_REPLICATION','true');
B. SHOW ORGANIZATION ACCOUNTS;
C. SHOW REGIONS;
D. GRANT ROLE ORGADMIN TO USER <username>;
E. SHOW USERS;

正解：B、C

解説：
Only the ORGADMIN role can run SHOW REGIONS and SHOW ORGANIZATION ACCOUNTS, which provide organization-wide information. These commands are not available to the ACCOUNTADMIN role.

質問 # 42
What information is required from the Identity Provider (IdP) to enable federated authentication in Snowflake? (Choose two.)

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

正解：D、E

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.

質問 # 43
A Snowflake account is configured with SCIM provisioning for user accounts and has bi-directional synchronization for user identities. An Administrator with access to SECURITYADMIN uses the Snowflake UI to create a user by issuing the following commands:
use role USERADMIN;
create or replace role DEVELOPER_ROLE;
create user PTORRES PASSWORD = 'hello world!' MUST_CHANGE_PASSWORD = FALSE
default_role = DEVELOPER_ROLE;
The new user named PTORRES successfully logs in, but sees a default role of PUBLIC in the web UI. When attempted, the following command fails:
use DEVELOPER_ROLE;
Why does this command fail?

A. The DEVELOPER_ROLE needs to be granted to SYSADMIN before user PTORRES will be able to use the role.
B. The new role will only take effect once the identity provider has synchronized by way of SCIM with the Snowflake account.
C. USERADMIN needs to explicitly grant the DEVELOPER_ROLE to the new USER.
D. The new role can only take effect after USERADMIN has logged out.

正解：C

解説：
Creating a user in Snowflake does not automatically grant them roles beyond PUBLIC. To use DEVELOPER_ROLE, the USERADMIN (or another role with MANAGE GRANTS privilege) must explicitly grant DEVELOPER_ROLE to PTORRES. Without this grant, the user cannot assume the role.
