질문 # 30
A critical database, 'PRODUCTION DB', in your Snowflake account was accidentally dropped. You need to restore it as quickly as possible, but you're unsure if Time Travel retention is sufficient. Which method guarantees restoration of the database even if it falls outside the Time Travel window?

A. Fail-safe cannot be directly accessed by the user for restoration purposes; it is only used by Snowflake Support in extreme disaster recovery scenarios.
B. Restore from a Snowflake-managed backup using the 'CREATE DATABASE ... FROM BACKUP' command. Specify the timestamp before the drop occurred.
C. Utilize the data cloning feature: 'CREATE DATABASE CLONE PRODUCTION_DB BEFORE (STATEMENT 'DROP DATABASE PRODUCTION_DB');'
D. Contact Snowflake Support and request restoration from Fail-safe.
E. Use the 'UNDROP DATABASE PRODUCTION command.

정답：A

설명：
Fail-safe is a last resort for data recovery managed entirely by Snowflake. Users cannot directly access or restore data from Fail- safe. Options B and C are valid for Time Travel, but fail if the data falls outside of that window. Option A is partially correct; you contact Snowflake support, who then might use fail-safe if appropriate, but option E is the most accurate answer. Option D uses Time Travel, which may not work.

질문 # 31
A data engineering team is implementing column-level security on a Snowflake table named 'CUSTOMER DATA containing sensitive PII. They want to mask the 'EMAIL' column for users in the 'ANALYST role but allow users in the 'DATA SCIENTIST role to view the unmasked email addresses. The 'ANALYST role already has SELECT privileges on the table. Which of the following steps are necessary to achieve this using a masking policy?

A. Create a masking policy with a CASE statement that checks the CURRENT ROLE() function to see if it's 'ANALYST'. If true, mask the email; otherwise, return the original email.
B. Create a masking policy that uses the CURRENT_USER() function to check if the current user belongs to the 'ANALYST' role.
C. Create a masking policy that uses the IS_ROLE_IN_SESSION('ANALYST') function to return a masked value if the analyst role is active in current session and the original value otherwise.
D. Create a dedicated view on 'CUSTOMER DATA' for analysts with the 'EMAIL' column masked using a CASE statement within the view's SELECT statement. Grant SELECT privilege to the ANALYST role on the view only.
E. Create a masking policy that uses the CURRENT ROLE() function to return a masked value if the current role is 'ANALYST and the original value otherwise.

정답：A,E

설명：
Options A and D are correct. They both use the 'CURRENT ROLE()' function within the masking policy to conditionally mask the email addresses based on the active role. Option B uses which checks if a role has been granted to the user which is not the intention. CURRENT_USER is not appropriate because the requirement is role-based. Creating a view (option E) is a valid but less scalable and maintainable solution compared to a masking policy. Creating a view will require more maintenance than creating a policy which is more integrated and scalable.

질문 # 32
You have a large dataset stored in AWS S3 in Parquet format. The data is constantly updated by an external process, but you need to run read-only analytical queries against the most current data in Snowflake without ingesting it. Which approach is the MOST efficient and cost-effective way to achieve this, considering minimal latency for query results?

A. Create a Snowflake external table pointing to the S3 location. Manually refresh the external table metadata periodically using the 'ALTER EXTERNAL TABLE REFRESH' command.
B. Use Snowpipe to continuously ingest the Parquet files from S3 into a Snowflake table.
C. Create an external table in Snowflake pointing to the S3 location. Configure automatic data refresh using the 'AUTO REFRESH' parameter and a notification integration.
D. Create a Snowflake internal stage, load the Parquet files into the stage periodically, and create a table from the staged files.
E. Create a view on top of the S3 files using a custom Java UDF to read Parquet data directly. Then, query the view.

정답：C

설명：
Option B is the most efficient. External tables allow querying data directly from S3 without ingestion. 'AUTO_REFRESH' and notification integration ensures the metadata is automatically updated when new files are added to S3, providing near real-time access. Options A and D involve data ingestion, which adds latency and storage costs. Option C requires manual intervention, and Option E using a Java UDF for Parquet reading is inefficient.

질문 # 33
A provider account is sharing a database named 'SHARED DB' through a share named 'MY SHARE. The consumer account has created a database named 'CONSUMER DB' from the share. The provider account revokes access to a table named 'SALES DATA within 'SHARED DB'. What will happen when a user in the consumer account attempts to query 'CONSUMER DB.SHARED SCHEMA.SALES DATA'?

A. The query will fail with an error message indicating that the table does not exist or the user does not have privileges.
B. The query will be automatically re-routed to another available share containing 'SALES DATA'.
C. The query will be cached based on the initial access, so users can continue query previous result based on same SQL
D. The query will execute successfully, but the user will receive an empty result set.
E. The query will execute successfully, but only return data that existed before the access was revoked.

정답：A

설명：
When access to a shared object is revoked in the provider account, the consumer account loses access to that object. Subsequent queries in the consumer account will fail with an error message indicating insufficient privileges or that the object does not exist. Snowflake does not automatically redirect queries to other shares or provide cached result once access is revoked.

질문 # 34
You are tasked with implementing a projection policy in Snowflake to restrict access to certain columns of the 'EMPLOYEE table based on the user's role. The table contains columns like 'EMPLOYEE 'NAME, 'SALARY', and 'DEPARTMENT. Users with the 'HR MANAGER role should have access to all columns, while other users should only be able to see 'EMPLOYEE ID, 'NAME, and DEPARTMENT. The initial attempt to create the projection policy results in an error. What could be the reasons?

A. Projection policies are not supported in Snowflake.
B. Projection policies can only be applied at the database level, not at the table level.
C. The EMPLOYEE table must have row-level security policies enabled before applying a projection policy.
D. The projection policy definition might contain syntax errors or reference non-existent roles or columns.
E. The user attempting to create the projection policy does not have the 'OWNERSHIP' privilege on the 'EMPLOYEE table.

정답：D,E

설명：
Options D and E are correct. To create a projection policy, the user needs the 'OWNERSHIP privilege on the table. A syntax error can cause an error. Option A is incorrect since projection policies are applied at the table or view level. Projection policies exist in Snowflake, and do not depend on Row Access Policies to be enabled so B and C are incorrect.
