최신 SnowPro Core COF-C02 무료샘플문제 (Q623-Q628):

질문 # 623
What is the MAXIMUM size limit for a record of a VARIANT data type?

A. 16MB
B. 128MB
C. 32MB
D. 8MB

정답：A

설명：
The maximum size limit for a record of a VARIANT data type in Snowflake is 16MB. This allows for storing semi-structured data types like JSON, Avro, ORC, Parquet, or XML within a single VARIANT column. References: Based on general database knowledge as of 2021.

질문 # 624
What is a best practice after creating a custom role?

A. Assign the custom role to the SYSADMIN role
B. Add__CUSTOM to all custom role names
C. Assign the custom role to the PUBLIC role
D. Create the custom role using the SYSADMIN role.

정답：A

설명：
Explanation
When creating roles that will serve as the owners of securable objects in the system, Snowflake recommends creating a hierarchy of custom roles, with the top-most custom role assigned to the system role SYSADMIN.
This role structure allows system administrators to manage all objects in the account, such as warehouses and database objects, while restricting management of users and roles to the USERADMIN role.

질문 # 625
In the query profiler view for a query, which components represent areas that can be used to help optimize query performance? (Select TWO)

A. Percentage scanned from cache
B. External bytes scanned
C. Bytes scanned
D. Number of partitions scanned
E. Bytes sent over the network

정답：C,D

질문 # 626
When should a stored procedure be created with caller's rights?

A. When the stored procedure needs to run with the privileges of the role that called the stored procedure
B. When the caller needs to be prevented from viewing the source code of the stored procedure
C. When the stored procedure needs to operate on objects that the caller does not have privileges on
D. When the caller needs to run a statement that could not execute outside of the stored procedure

정답：A

설명：
Stored procedures in Snowflake can be created with either 'owner's rights' or 'caller's rights'. A stored procedure created with caller's rights executes with the privileges of the role that calls the procedure, not the privileges of the role that owns the procedure. This is particularly useful in scenarios where the procedure needs to perform operations that depend on the caller's access permissions, ensuring that the procedure can only access objects that the caller is authorized to access.

질문 # 627
What is it called when a customer managed key is combined with a Snowflake managed key to create a composite key for encryption?

A. Hierarchical key model
B. Tri-secret secure encryption
C. Client-side encryption
D. Key pair authentication

정답：B

설명：
Tri-secret secure encryption is a security model employed by Snowflake that involves combining a customer-managed key with a Snowflake-managed key to create a composite key for encrypting data. This model enhances data security by requiring both the customer-managed key and the Snowflake-managed key to decrypt data, thus ensuring that neither party can access the data independently. It represents a balanced approach to key management, leveraging both customer control and Snowflake's managed services for robust data encryption.
