Snowflake SnowPro Core Certification Exam Sample Questions (Q717-Q722):

NEW QUESTION # 717
When working with table MY_TABLE that contains 10 rows, which sampling query will always return exactly 5 rows?

Answer: B

Explanation:
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.


NEW QUESTION # 718
Regardless of which notation is used, what are considerations for writing the column name and element names when traversing semi-structured data?

Answer: C

Explanation:
When querying semi-structured data in Snowflake, the behavior towards case sensitivity is distinct between column names and the names of elements within the semi-structured data. Column names follow the general SQL norm of being case-insensitive, meaning you can reference them in any case without affecting the query.
However, element names within JSON, XML, or other semi-structured data are case-sensitive. This distinction is crucial for accurate data retrieval and manipulation in Snowflake, especially when working with JSON objects where the case of keys can significantly alter the outcome of queries.

NEW QUESTION # 719
How can network and private connectivity security be managed in Snowflake?

Answer: D

Explanation:
* Snowflake uses network policies to restrict access to specific IP ranges.
* Customers can configure these policies using IPv4 IP addresses to define the allowed or blocked range of addresses for account access.
* This enhances network security by limiting access to trusted networks only.

NEW QUESTION # 720
Which table function will return the output of a previously-run command?

Answer: A


NEW QUESTION # 721
Which semi-structured file format is a compressed, efficient, columnar data representation?

Answer: D

Explanation:
Parquet is a columnar storage file format that is optimized for efficiency in both storage and processing. It supports compression and encoding schemes that significantly reduce the storage space needed and speed up data retrieval operations, making it ideal for handling large volumes of data. Unlike JSON or TSV, which are row-oriented and typically uncompressed, Parquet is designed specifically for use with big data frameworks, offering advantages in terms of performance and cost when storing and querying semi-structured data.
