Snowflake SnowPro Certification Practice Test

Which of the following describes Snowflake's concurrency feature?

1. Limited concurrent queries

2. High concurrency support

3. Dedicated user sessions only

4. Restricted data access

The correct answer is: High concurrency support

Snowflake's concurrency feature is characterized by high concurrency support, allowing multiple users to query the database simultaneously without performance degradation. Unlike traditional databases that may struggle with too many concurrent queries leading to contention and locked resources, Snowflake utilizes its unique architecture to hold and manage workloads efficiently. This high degree of concurrency is made possible by separating compute from storage, whereby compute resources can scale independently of data storage. This means that Snowflake can allocate additional virtual warehouses to handle increased query loads without impacting other users. As a result, many users can submit queries and perform operations at the same time, empowering teams to work collaboratively without hindrance. In this context, options reflecting limited concurrent queries, dedicated user sessions only, or restricted data access do not align with Snowflake's design and capabilities, which emphasize flexibility and robust support for concurrent user activities.
