Snowflake ARA-C01 Exam With Confidence Using Practice Dumps

This question evaluates deep understanding of Snowflake RBAC, managed access schemas, and privilege inheritance, all of which are core SnowPro Architect topics. The schema DEV_TEST_DB.SCHTEST is created WITH MANAGED ACCESS, meaning that only the schema owner (or a higher role in the hierarchy) can grant object privileges such as SELECT on tables within the schema.

The table CURRENCY is created by the role DEV_PROJ_OWN, making it the table owner. As the owner, DEV_PROJ_OWN implicitly has full privileges on the table, including SELECT. Therefore, option B succeeds because the role selecting the data owns the table.

In option A, DEV_PROJ_OWN explicitly grants SELECT on the table to ANALYST_PROJ. Since this grant is performed by the schema/table owner and the role ANALYST_PROJ already has USAGE on both the database and schema, the subsequent SELECT succeeds. This makes A valid.

Option C fails because SYSADMIN does not inherit privileges from DEV_SYSADMIN or DEV_PROJ_OWN; Snowflake role inheritance is directional and not lateral. Option D fails for the same reason—MAPPING_ROLE has no privileges on the database or schema. Option E fails because ACCOUNTADMIN does not automatically bypass RBAC; without explicit USAGE and SELECT, access is denied.

An external table schema defines the columns and data types of the data stored in an external stage. All external tables include the following columns by default:

VALUE: A VARIANT type column that represents a single row in the external file.

METADATA$FILENAME: A pseudocolumn that identifies the name of each staged data file included in the external table, including its path in the stage.

METADATA$FILE_ROW_NUMBER: A pseudocolumn that shows the row number for each record in a staged data file.

You can also create additional virtual columns as expressions using the VALUE column and/or the pseudocolumns. However, the following columns are not valid for external tables and cannot be included in the schema:

METADATASROW_ID: This column is only available for internal tables and shows the unique identifier for each row in the table.

METADATASISUPDATE: This column is only available for internal tables and shows whether the row was inserted or updated by a merge operation.

METADATASEXTERNAL TABLE PARTITION: This column is not a valid column name and does not exist in Snowflake.

 Introduction to External Tables, CREATE EXTERNAL TABLE

 Option C is the correct answer because it allows the company to share data privately with the customer across different cloud platforms and regions. The company can create a new Snowflake account in Azure East US 2 (Virginia) and set up replication between AWS us-west-2 (Oregon) and Azure East US 2 (Virginia) for the database objects to be shared. This way, the company can ensure that the data is always up to date and consistent in both accounts. The company can then create a share and add the database privileges to the share, and alter the share and add the customer’s Snowflake account to the share. The customer can then access the shared data from their own Snowflake account in Azure East US 2 (Virginia).

Option A is incorrect because the Snowflake Marketplace is not a private way of sharing data. The Snowflake Marketplace is a public data exchange platform that allows anyone to browse and subscribe to data sets from various providers. The company would not be able to control who can access their data if they use the Snowflake Marketplace.

Option B is incorrect because it requires the customer to create a new Snowflake account in Azure East US 2 (Virginia), which may not be feasible or desirable for the customer. The customer may already have an existing Snowflake account in a different cloud platform or region, and may not want to incur additional costs or complexity by creating a new account.

Option D is incorrect because it involves creating a reader account in Azure East US 2 (Virginia), which is a limited and temporary way of sharing data. A reader account is a special type of Snowflake account that can only access data from a single share, and has a fixed duration of 30 days. The company would have to manage the reader account’s URL and credentials, and renew the account every 30 days. The customer would not be able to use their own Snowflake account to access the shared data, and would have to rely on the company’s reader account.
