Snowflake SnowPro Core Certification Exam 認定 COF-C02 試験問題 (Q302-Q307):

質問 # 302
The Snowflake VARIANT data Type imposes a 16 MB size limit on what?

A. A view
B. A file in a stage
C. An individual column
D. An individual row

正解：C

解説：
* The VARIANT data type in Snowflake is used for semi-structured data such as JSON, Avro, or Parquet.
* A 16 MB size limit applies to an individual column when storing VARIANT data in a table.
* This size restriction ensures efficient storage and processing of semi-structured data.
References:
* Snowflake Documentation: VARIANT Data Type
* Snowflake Table Storage Limitations

質問 # 303
How many credits does a size 3X-Large virtual warehouse consume if it runs continuously for 2 hours?

A. 0
B. 1
C. 2
D. 3

正解：B

解説：
In Snowflake, the consumption of credits by a virtual warehouse is determined by its size and the duration for which it runs. A size 3X-Large virtual warehouse consumes 128 credits if it runs continuously for 2 hours.
This consumption rate is based on the principle that larger warehouses, capable of providing greater computational resources and throughput, consume more credits per hour of operation. The specific rate of consumption is defined by Snowflake's pricing model and the scale of the virtual warehouse.

質問 # 304
If 3 size Small virtual warehouse is made up of two servers, how many servers make up a Large warehouse?

A. 0
B. 1
C. 2
D. 3

正解：A

解説：
In Snowflake, each size increase in virtual warehouses doubles the number of servers. Therefore, if a sizeSmall virtual warehouse is made up of two servers, a Large warehouse, which is two sizes larger, would be made up of eight servers (2 servers for Small, 4 for Medium, and 8 for Large)2.
Size specifies the amount of compute resources available per cluster in a warehouse. Snowflake supports the following warehouse sizes:

質問 # 305
What target locations can be used when unloading data using the COPY INTO <location> command? (Select TWO)

A. A Snowflake stream
B. A local file system
C. A Snowflake stage
D. Cloud storage in Google (GCP), AWS, or Microsoft Azure
E. A Snowflake schema

正解：C、D

解説：
The COPY INTO <location> command is used to unload data from Snowflake tables to external locations, typically cloud storage or a Snowflake stage. Supported destinations include:
* External stages: e.g., S3, Azure Blob Storage, Google Cloud Storage
* Internal named stages: Snowflake-managed storage
Local file systems are not supported as unload targets.
Reference:
Snowflake Docs: COPY INTO <location> (unloading)
"You can unload data to: Internal Named Stages and External Stages (S3, Azure, GCS)"

質問 # 306
What command is used to export or unload data from Snowflake?

A. COPY INTO @mystage
B. GET @mystage
C. PUT @mystage
D. INSERT @mystage

正解：C

解説：
The command used to export or unload data from Snowflake to a stage (such as a file in an S3 bucket, Azure Blob Storage, or Google Cloud Storage) is the PUT command. The PUT command is designed to upload data files from a local file system (in the case of SnowSQL or other client) or a virtual warehouse to a specified stage. This functionality is critical for scenarios where data needs to be extracted from Snowflake for use in external systems, backups, or further processing.
The syntax for the PUT command follows the structure: PUT file://<local_file_path> @<stage_name>, where <local_file_path> specifies the path to the file(s) on the local file system that you wish to upload, and <stage_name> specifies the destination stage in Snowflake.
It's important to distinguish that the PUT command is used for exporting data out of Snowflake, whereas the COPY INTO <table> command is used for importing data into Snowflake from a stage. The GET command, on the other hand, is used to download files from a stage to the local file system, essentially the inverse operation of the PUT command.
