Administrator

1.When a role is dropped, which role inherits ownership of objects owned by the dropped role? A. The SYSADMIN role B. The role above the dropped role in the RBAC hierarchy C. The role executing the command D. The SECURITYADMIN role Answer: B Explanation: According to the Snowflake documentation1, when a role is dropped, ownership of all objects owned by the dropped role is transferred to the role that is directly above the dropped role in the role hierarchy. This is to ensure that there is always a single owner for each object in the system. 1: Drop Role | Snowflake Documentation 2.Company A uses Snowflake to manage audio files of call recordings. Company A hired Company B, who also uses Snowflake, to transcribe the audio files for further analysis. Company A's Administrator created a share. What object should be added to the share to allow Company B access to the files? A. A secure view with a column for file URLs. B. A secure view with a column for pre-signed URLs. C. A secure view with a column for METADATA$FILENAME. D. A secure view with a column for the stage name and a column for the file path. Answer: B Explanation: According to the Snowflake documentation1, pre-signed URLs are required to access external files in a share. A secure view can be used to generate pre-signed URLs for the audio files stored in an external stage and expose them to the consumer account. Option A is incorrect because file URLs alone are not sufficient to access external files in a share. Option C is incorrect because METADATA$FILENAME only returns the file name, not the full path or URL. Option D is incorrect because the stage name and file path are not enough to generate pre-signed URLs. 3.A retailer uses a TRANSACTIONS table (100M rows, 1.2 TB) that has been clustered by the STORE_ID column (varchar (50)). The vast majority of analyses on this table are grouped by STORE_ID to look at store performance. There are 1000 stores operated by the retailer but most sales come from only 20 stores. The Administrator notes that most queries are currently experiencing poor pruning, with large amounts of bytes processed by even simple queries. Why is this occurring? A. The STORE_ID should be numeric. B. The table is not big enough to take advantage of the clustering key. C. Sales across stores are not uniformly distributed. D. The cardinality of the stores to transaction count ratio is too low to use the STORE_ID as a clustering key. Answer: C Explanation: According to the Snowflake documentation1, clustering keys are most effective when the data is evenly

A. Reset a Snowflake user's password B. Manage system grants C. Create new users D. Create new roles Answer: B Explanation: According to the Snowflake documentation1, the SECURITYADMIN role is responsible for managing all grants on objects in the account, including system grants. The USERADMIN role can only create and manage users and roles, but not grant privileges on other objects. Therefore, the function that is unique to the SECURITYADMIN role is to manage system grants. Option A is incorrect because both roles can reset a user’s password. Option C is incorrect because both roles can create new users. Option D is incorrect because both roles can create new roles. 6.An Administrator has a table named SALES_DATA which needs some edits, but the Administrator does not want to change the main table data. The Administrator decides to make a transient copy of this table and wants the transient table to have all the same permissions as the original table. How can the Administrator create the transient table so it inherits the same permissions as the original table, and what considerations need to be made concerning the requirements? (Select TWO). A. Use the following SQL command: create transient table TRANSIENT_SALES_DATA as select * from SALES_DATA; B. Use the following SQL command: create transient table TRANSIENT SALES DATA as select * from SALES_DATA copy grants; C. Use the following SQL commands: create transient table TRANSIENT_SALES_DATA like SALES_DATA copy grants; insert into TRANSIENT_SALES_DATA select * from SALES_DATA; D. Transient tables will persist until explicitly dropped and contribute to overall storage costs. E. Transient tables will be purged at the end of the user session and do not have any Fail-safe period. Answer: BD Explanation: According to the Snowflake documentation1, the COPY GRANTS option can be used to copy all privileges, except OWNERSHIP, from the existing table to the new transient table. This option also preserves any future grants defined for the object type in the schema. Option A is incorrect because it does not copy any grants from the original table. Option C is incorrect because it does not copy the data from the original table, only the structure and grants. Option E is incorrect because transient tables are not session-based and do not have a Fail-safe period, but they do have a Time Travel retention period2. 1: CREATE TABLE | Snowflake Documentation 2: Working with Temporary and Transient Tables | Snowflake Documentation 7.Which actions are considered breaking changes to data that is shared with consumers in the Snowflake Marketplace? (Select TWO). A. Dropping a column from a table

B. Deleting data from a table C. Unpublishing the data listing D. Renaming a table E. Adding region availability to the listing Answer: AD Explanation: According to the Snowflake documentation1, breaking changes are changes that affect the schema or structure of the shared data, such as dropping or renaming a column or a table. These changes may cause errors or unexpected results for the consumers who query the shared data. Deleting data from a table, unpublishing the data listing, or adding region availability to the listing are not breaking changes, as they do not alter the schema or structure of the shared data. 1: Managing Data Listings in Snowflake Data Marketplace | Snowflake Documentation 8.What are the MINIMUM grants required on the database, schema, and table for a stream to be properly created and managed? A. Database: Usage Schema: Usage Table: Select, Create Stream B. Database: Usage Schema: Usage Table: Select C. Database: Usage, Create Stream Schema: Usage Table: Select D. Database: Usage Schema: Usage, Create Stream Table: Select Answer: A 9.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. 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. B. Create a separate table for all the non-Pll columns and grant the role DEVELOPER access to the new
