Question 16

A JSON object is loaded into a column named data using a Snowflake variant datatype. The root node of the object is BIKE. The child attribute for this root node is BIKEID.
Which statement will allow the user to access BIKEID?

Correct Answer: C
In Snowflake, when accessing elements within a JSON object stored in a variant column, the correct syntax involves using a colon (:) to navigate the JSON structure. The BIKEID attribute, which is a child of the BIKE root node in the JSON object, is accessed using data:BIKE.BIKEID. This syntax correctly references the path through the JSON object, utilizing the colon for JSON field access and dot notation to traverse the hierarchy within the variant structure.References: Snowflake documentation on accessing semi-structured data, which outlines how to use the colon and dot notations for navigating JSON structures stored in variant columns.

Question 17

When working with table MY_TABLE that contains 10 rows, which sampling query will always return exactly 5 rows?

Correct Answer: C
In Snowflake, SAMPLE (5 ROWS) ensures an exact count of 5 rows is returned from MY_TABLE, regardless of table size. This is different from SAMPLE SYSTEM or SAMPLE BERNOULLI, which use percentage-based sampling, potentially returning varying row counts based on probabilistic methods.
The ROWS option is deterministic and does not depend on percentage, making it ideal when an exact row count is required.

Question 18

What should be considered when deciding to use a secure view? (Select TWO).

Correct Answer: A,C
When deciding to use a secure view, several considerations come into play, especially concerning security and performance:
A . No details of the query execution plan will be available in the query profiler: Secure views are designed to prevent the exposure of the underlying data and the view definition to unauthorized users. Because of this, the detailed execution plans for queries against secure views are not available in the query profiler. This is intended to protect sensitive data from being inferred through the execution plan.
C . Secure views do not take advantage of the same internal optimizations as standard views: Secure views, by their nature, limit some of the optimizations that can be applied compared to standard views. This is because they enforce row-level security and mask data, which can introduce additional processing overhead and limit the optimizer's ability to apply certain efficiencies that are available to standard views.
B . Once created, there is no way to determine if a view is secure or not is incorrect because metadata about whether a view is secure can be retrieved from the INFORMATION_SCHEMA views or by using the SHOW VIEWS command.
D . It is not possible to create secure materialized views is incorrect because the limitation is not on the security of the view but on the fact that Snowflake currently does not support materialized views with the same dynamic data masking and row-level security features as secure views.
E . The view definition of a secure view is still visible to users by way of the information schema is incorrect because secure views specifically hide the view definition from users who do not have the privilege to view it, ensuring that sensitive information in the definition is not exposed.

Question 19

What activities can a user with the ORGADMIN role perform? (Select TWO).

Correct Answer: B,D
The ORGADMIN role in Snowflake is designed to manage organization-level activities. This role can perform several tasks that span across multiple accounts within the organization.
View Usage Information: The ORGADMIN role can view usage statistics and billing information for all accounts within the organization.
-- Example: Viewing usage information
SELECT *
FROM organization_usage_history;
Enable Database Replication: The ORGADMIN role has the authority to enable and manage database replication for accounts within the organization.
-- Example: Enabling database replication
ALTER DATABASE my_database ENABLE REPLICATION TO ACCOUNT other_account; References:
Snowflake Documentation: Organization Administration
Snowflake Documentation: Replication
insert code

Question 20

Which items are considered schema objects in Snowflake? (Select TWO).

Correct Answer: A,B
In Snowflake, schema objects include Pipes and File formats. Pipes are used for continuous data loading, and File formats specify the format of data files used in loading and unloading operations within Snowflake
