Snowflake SnowPro Core Certification Exam Sample Questions (Q1093-Q1098):

NEW QUESTION # 1093
What information does the Query Profile provide?

Answer: D

Explanation:
The Query Profile in Snowflake provides a graphical representation and statistics for each component of the query's execution plan. This includes details such as the execution time, the number of rows processed, and the amount of data scanned for each operation within the query. The Query Profile is a crucial tool for understanding and optimizing the performance of queries, as it helps identify potential bottlenecks and inefficiencies.
Reference:
Snowflake Documentation: Understanding the Query Profile


NEW QUESTION # 1094
A user needs to load Snowflake files from a stage that contains data from the past 5 years while using the least amount of operational overhead. The file names follow a specific format, such as files ending in _01.gz.
Which command should be used to load the data from 2024?

Answer: A

Explanation:
The correct answer is B. Use the COPY INTO command using the PATTERN parameter to define the needed files .
The PATTERN parameter in the COPY INTO < table > command allows Snowflake to load only files whose names match a specified regular expression. This is useful when a stage contains many files and the required files can be identified by a naming pattern, such as year or suffix.
Why B is correct:
The user needs to load a subset of staged files from a 5-year collection and wants the least operational overhead. Using PATTERN avoids manually listing files, removing files, or downloading and restaging data.
Example concept:
COPY INTO target_table
FROM @my_stage
PATTERN = ' .*2024.*_01[.]gz ' ;
Why the other options are incorrect:
A). Individually loading files creates more manual work and higher operational overhead.
C). Removing unwanted files is risky and unnecessary. It also changes the staged file set.
D). Downloading files with GET, creating a new stage, and reloading files adds unnecessary operational complexity.
Official Snowflake documentation reference:
Snowflake documentation explains that the PATTERN option in COPY INTO < table > specifies a regular expression pattern used to match staged file names for loading.
Reference: Snowflake Documentation - COPY INTO < table > ; Snowflake Documentation - PATTERN copy option; SnowPro Core Study Guide - Data Loading and Unloading.

These actions help manage and control resource usage and costs within Snowflake.

Snowflake Documentation: Resource Monitors
