Snowflake SnowPro Core Certification Exam Sample Questions (Q255-Q260):

NEW QUESTION # 255
To use the overwrite option on insert, which privilege must be granted to the role?

  • A. UPDATE
  • B. DELETE
  • C. truncate
  • D. SELECT

Answer: B

Explanation:
To use the overwrite option on insert in Snowflake, the DELETE privilege must be granted to the role. This is because overwriting data during an insert operation implicitly involves deleting the existing data before inserting the new data.
* Understanding the Overwrite Option: The overwrite option (INSERT OVERWRITE) allows you to replace existing data in a table with new data. This operation is particularly useful for batch-loading scenarios where the entire dataset needs to be refreshed.
* Why DELETE Privilege is Required: Since the overwrite operation involves removing existing rows in the table, the executing role must have the DELETE privilege to carry out both the deletion of old data and the insertion of new data.
* Granting DELETE Privilege:
* To grant the DELETE privilege to a role, an account administrator can execute the following SQL command:
sqlCopy code
GRANT DELETE ON TABLE my_table TO ROLE my_role;
Reference: For additional details on inserting data with the overwrite option and the required privileges, consult the Snowflake documentation on data loading:

NEW QUESTION # 256
Which of the following Snowflake capabilities are available in all Snowflake editions? (Select TWO)

  • A. Column-level security to apply data masking policies to tables and views
  • B. Object-level access control
  • C. Up to 90 days of data recovery through Time Travel
  • D. Customer-managed encryption keys through Tri-Secret Secure
  • E. Automatic encryption of all data

Answer: B,E

Explanation:
In all Snowflake editions, two key capabilities are universally available:
B . Automatic encryption of all data: Snowflake automatically encrypts all data stored in its platform, ensuring security and compliance with various regulations. This encryption is transparent to users and does not require any configuration or management.
D . Object-level access control: Snowflake provides granular access control mechanisms that allow administrators to define permissions at the object level, including databases, schemas, tables, and views. This ensures that only authorized users can access specific data objects.
These features are part of Snowflake's commitment to security and governance, and they are included in every edition of the Snowflake Data Cloud.

NEW QUESTION # 257
How does the search optimization service help Snowflake users improve query performance?

  • A. II maintains a persistent data structure that keeps track of the values of the table's columns m each of its micro-partitions.
  • B. It scans the micro-partitions based on the joins used in the queries and scans only join columns.
  • C. It scans the local disk cache to avoid scans on the tables used in the Query.
  • D. It keeps track of running queries and their results and saves those extra scans on the table.

Answer: A

Explanation:
The search optimization service in Snowflake enhances query performance by maintaining a persistent data structure. This structure indexes the values of table columns across micro-partitions, allowing Snowflake to quickly identify which micro-partitions contain relevant data for a query. By efficiently narrowing down the search space, this service reduces the amount of data scanned during query execution, leading to faster response times and more efficient use of resources.

NEW QUESTION # 258
If 3 size Small virtual warehouse is made up of two servers, how many servers make up a Large warehouse?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: A

Explanation:
In Snowflake, each size increase in virtual warehouses doubles the number of servers. Therefore, if a size Small virtual warehouse is made up of two servers, a Large warehouse, which is two sizes larger, would be made up of eight servers (2 servers for Small, 4 for Medium, and 8 for Large)2.
Size specifies the amount of compute resources available per cluster in a warehouse. Snowflake supports the following warehouse sizes:

NEW QUESTION # 259
User1, who has the SYSADMIN role, executed a query on Snowsight. User2, who is in the same Snowflake account, wants to view the result set of the query executed by User1 using the Snowsight query history.
What will happen if User2 tries to access the query history?

  • A. User2 will be unable to view the result set of the query executed by User1.
  • B. If User2 has the ACCOUNTADMIN role they will be able to see the results.
  • C. If User2 has the sysadmin role they will be able to see the results.
  • D. If User2 has the securityadmin role they will be able to see the results.

Answer: B

Explanation:
In Snowflake, the query history and the results of queries executed by a user are accessible based on the roles and permissions. If User1 executed a query with the SYSADMIN role, User2 would be able to view the result set of that query executed by User1 only if User2 has the ACCOUNTADMIN role. The ACCOUNTADMIN role has the broadest set of privileges, including the ability to access all aspects of the account's operation, data, and query history, thus enabling User2 to view the results of queries executed by other users.
