NEW QUESTION # 769
Which Snowflake command can be used to unload the result of a query to a single file?
Answer: A
Explanation:
The Snowflake command to unload the result of a query to a single file is COPY INTO <internal stage> with SINGLE = TRUE followed by a GET command to download the file.This command unloads the query result into a single file in the specified internal stage
NEW QUESTION # 770
What are key characteristics of virtual warehouses in Snowflake? (Select TWO).
Answer: A,B
Explanation:
Virtual warehouses in Snowflake can be started and stopped at any time, providing flexibility in managing compute resources. They can also be resized at any time, even while running, toaccommodate varying workloads910. References: [ COF-C03 ] SnowPro Core Certification Exam Study Guide
NEW QUESTION # 771
Which Snowflake objects use storage? (Select TWO)
Answer: A,D
NEW QUESTION # 772
Which Snowflake tasks are managed in the cloud services layer? Select TWO.
Answer: B,D
Explanation:
The correct answers are C. Metadata management and E. Query parsing .
Snowflake's architecture has three main layers:
Cloud Services Layer
Query Processing Layer / Compute Layer
Database Storage Layer
The cloud services layer coordinates Snowflake activities and handles services such as authentication, infrastructure management, metadata management, query parsing and optimization, access control, and transaction management.
Why C is correct:
Metadata management is handled by the cloud services layer. This includes metadata about tables, micro- partitions, query optimization statistics, and access-related metadata.
Why E is correct:
Query parsing and optimization are handled by the cloud services layer before execution is assigned to compute resources.
Why the other options are incorrect:
A). Performance tuning is not usually described as a discrete cloud services task. Snowflake automatically optimizes many operations, but this option is too broad.
B). Query acceleration uses additional compute resources and is a performance feature, not a core task of the cloud services layer.
D). Query processing is performed by virtual warehouses in the compute layer, not by the cloud services layer.
Official Snowflake documentation reference:
Snowflake documentation explains that the cloud services layer manages authentication, infrastructure management, metadata, query parsing and optimization, access control, and transaction management.

NEW QUESTION # 773
A reporting dashboard uses a dedicated warehouse that automatically suspends after five minutes of inactivity. Similar queries run sporadically, with gaps exceeding five minutes. Users notice that the first query after suspension takes significantly longer than subsequent queries while the warehouse remains active.
How should query performance be improved?
Answer: D
Explanation:
A running virtual warehouse maintains a local cache of table data. When the warehouse suspends, that cache is dropped. Because the dashboard's query gaps exceed the five-minute auto-suspend period, the warehouse repeatedly suspends, and the first query after each resume runs with a cold cache. This makes it slower than subsequent similar queries. Increasing AUTO_SUSPEND allows the warehouse to remain active longer between dashboard requests and preserves the cache for reuse. Snowflake recommends an auto-suspend value of at least ten minutes for BI and SELECT-oriented query warehouses when cache reuse is important. This setting involves a cost trade-off because an idle but running warehouse continues consuming credits. Therefore, the selected value should reflect the actual interval between dashboard queries.
