Snowflake SnowPro Core Certification Exam COF-C02 Prüfungsfragen mit Lösungen (Q543-Q548):

543. Frage
Which type of workload is recommended for Snowpark-optimized virtual warehouses?

A. Workloads with ad hoc analytics
B. Workloads with unpredictable data volumes for each query
C. Workloads that have large memory requirements
D. Workloads that are queried with small table scans and selective filters

Antwort: C

Begründung:
Snowpark-optimized virtual warehouses in Snowflake are designed to efficiently handle workloads with large memory requirements. Snowpark is a developer framework that allows users to write code in languages like Scala, Java, and Python to process data in Snowflake. Given the nature of these programming languages and the types of data processing tasks they are typically used for, having a virtual warehouse that can efficiently manage large memory-intensive operations is crucial.
* Understanding Snowpark-Optimized Virtual Warehouses:
* Snowpark allows developers to build complex data pipelines and applications within Snowflake using familiar programming languages.
* These virtual warehouses are optimized to handle the execution of Snowpark workloads, which often involve large datasets and memory-intensive operations.
* Large Memory Requirements:
* Workloads with large memory requirements include data transformations, machine learning model training, and advanced analytics.
* These operations often need to process significant amounts of data in memory to perform efficiently.
* Snowpark-optimized virtual warehouses are configured to provide the necessary memory resources to support these tasks, ensuring optimal performance and scalability.
* Other Considerations:
* While Snowpark can handle other types of workloads, its optimization for large memory tasks makes it particularly suitable for scenarios where data processing needs to be done in-memory.
* Snowflake's ability to scale compute resources dynamically also plays a role in efficiently managing large memory workloads, ensuring that performance is maintained even as data volumes grow.

544. Frage
What value provides information about disk usage for operations where intermediate results do not fit in memory in a Query Profile?

A. IO
B. Network
C. Spilling
D. Pruning

Antwort: C

Begründung:
In Snowflake, when a query execution requires more memory than what is available, Snowflake handles these situations by spilling the intermediate results to disk. This process is known as "spilling." The Query Profile in Snowflake includes a metric that helps users identify when and how much data spilling occurs during the execution of a query. This information is crucial for optimizing queries as excessive spilling can significantly slow down query performance. The value that provides this information about disk usage due to intermediate results not fitting in memory is appropriately labeled as "Spilling" in the Query Profile.
Reference:
Snowflake Documentation on Query Profile and Performance: This section explains the various components of the query profile, including the spilling metric, which indicates disk usage for operations where intermediate results exceed available memory.

545. Frage
What MINIMUM permissions are required to create a pipe in Snowflake? (Select TWO).

A. SELECT and INSERT on the table in the pipe definition
B. USAGE on the virtual warehouse
C. CREATE SCHEMA at the database level
D. OWNERSHIP on the table in the pipe definition
E. CREATE PIPE at the schema level

Antwort: A,E

546. Frage
Which table function is used to perform additional processing on the results of a previously-run query?

A. QUERY_HISTORY
B. RESULT_SCAN
C. QUERY HISTORY BY SESSION
D. DESCRIBE_RESULTS

Antwort: B

Begründung:
The RESULT_SCAN table function is used in Snowflake to perform additional processing on the results of a previously-run query. It allows users to reference the result set of a previous query by its query ID, enabling further analysis or transformations without re-executing the original query.
Reference:
Snowflake Documentation: RESULT_SCAN

547. Frage
The following JSON is stored in a VARIANT column called src of the CAR_SALES table:

A user needs to extract the dealership information from the JSON.
How can this be accomplished?

A. select src.dealership from car_sales;
B. select dealership from car_sales;
C. select src:Dealership from car_sales;
D. select src:dealership from car_sales;

Antwort: A

Begründung:
In Snowflake, to extract a specific element from a JSON stored in a VARIANT column, the correct syntax is to use the dot notation. Therefore, the query select src.dealership from car_sales; will return the dealership information contained within each JSON object in the src column.
References: For a detailed explanation, please refer to the Snowflake documentation on querying semi- structured data.
