Which data type can be used to store geospatial data in Snowflake?

Variant
Variant
Object
Object
Geometry
Geometry
Geography
Geography
Suggested answer: D

Explanation:

Snowflake supports two geospatial data types:GEOGRAPHYandGEOMETRY. TheGEOGRAPHYdata type is used to store geospatial data that models the Earth as a perfect sphere, which is suitable for global geospatial data. This data type follows the WGS 84 standard and is used for storing points, lines, and polygons on the Earth's surface. TheGEOMETRYdata type, on the other hand, represents features in a planar (Euclidean, Cartesian) coordinate system and is typically used for local spatial reference systems.Since the question specifically asks about geospatial data, which commonly refers to Earth-related spatial data, the correct answer isGEOGRAPHY3.References:[COF-C02] SnowPro Core Certification Exam Study Guide

What is the Fail-safe period for a transient table in the Snowflake Enterprise edition and higher?

0 days
0 days
1 day
1 day
7 days
7 days
14 days
14 days
Suggested answer: A

Explanation:

The Fail-safe period for a transient table in Snowflake, regardless of the edition (including Enterprise edition and higher), is 0 days. Fail-safe is a data protection feature that provides additional retention beyond the Time Travel period for recovering data in case of accidental deletion or corruption. However, transient tables are designed for temporary or short-term use and do not benefit from the Fail-safe feature, meaning that once their Time Travel period expires, data cannot be recovered.

TABLES
TABLE_STORAGE_METRICS
TABLE_STORAGE_METRICS
STORAGE_DAILY_HISTORY
STORAGE_DAILY_HISTORY
STORAGE USAGE
STORAGE USAGE
Suggested answer: B

Explanation:

The TABLE_STORAGE_METRICS view can be used to determine if a table has frequent row updates or deletes. This view provides detailed metrics on the storage utilization of tables within Snowflake, including metrics that reflect the impact of DML operations such as updates and deletes on table storage. For example, metrics related to the number of active and deleted rows can help identify tables that experience high levels of row modifications, indicating frequent updates or deletions.
