問題 #838
The effects of query pruning can be observed by evaluating which statistics? (Select TWO).
答案：B,E
問題 #839
What Snowflake features allow virtual warehouses to handle high concurrency workloads? (Select TWO)
答案：A,D
解題說明：
Snowflake's architecture is designed to handle high concurrency workloads through several features, two of which are particularly effective:
* B. The use of warehouse auto scaling: This feature allows Snowflake to automatically adjust the compute resources allocated to a virtual warehouse in response to the workload. If there is an increase in concurrent queries, Snowflake can scale up the resources to maintain performance.
* D. Use of multi-clustered warehouses: Multi-clustered warehouses enable Snowflake to run multiple clusters of compute resources simultaneously. This allows for the distribution of queries across clusters, thereby reducing the load on any single cluster and improving the system's ability to handle a high number of concurrent queries.
These features ensure that Snowflake can manage varying levels of demand without manual intervention, providing a seamless experience even during peak usage.

問題 #840
Which cache type is used to cache data output from SQL queries?
答案：B
解題說明：
The Result cache is used in Snowflake to cache the data output from SQL queries. This feature is designed to improve performance by storing the results of queries for a period of time. When the same or similar query is executed again, Snowflake can retrieve the result from this cache instead of re-computing the result, which saves time and computational resources.

問題 #841
How can a Snowflake user access a JSON object, given the following table? (Select TWO).
答案：B,E
解題說明：
To access a JSON object in Snowflake, dot notation is used where the path to the object is specified after the column name containing the JSON data. Both lowercase and uppercase can be used for attribute names, so both "name" and "Name" are valid. References: [COF-C02] SnowPro Core Certification Exam Study Guide
