Key architectural difference between Snowflake and traditional data warehouses

Which architectural feature best distinguishes Snowflake from traditional data warehouses?

A Snowflake separates compute and storage layers allowing independent scaling.

B Snowflake stores data only in on-premises servers for faster access.

C Snowflake requires manual tuning of indexes and partitions.

D Snowflake uses a single monolithic architecture combining compute and storage tightly.

💡 Hint

Think about how Snowflake handles resources compared to older systems.

Snowflake's architecture separates compute and storage, enabling flexible scaling and cost efficiency, unlike traditional warehouses that tightly couple these layers.

Snowflake's handling of concurrent queries vs traditional warehouses

How does Snowflake handle multiple users running queries at the same time compared to traditional data warehouses?

A Snowflake merges all queries into a single process to optimize speed.

B Snowflake queues all queries and runs them one by one to maintain order.

C Snowflake limits the number of concurrent queries to one per account.

D Snowflake creates separate virtual warehouses for each workload to avoid resource contention.

💡 Hint

Consider how Snowflake isolates workloads.

Snowflake uses virtual warehouses that can run independently, allowing many queries to run simultaneously without slowing each other down.

❓ security

Data encryption differences in Snowflake vs traditional warehouses

Which statement correctly describes Snowflake's approach to data encryption compared to traditional data warehouses?

A Traditional warehouses always encrypt data at rest by default, Snowflake does not.

B Snowflake requires manual encryption setup for data at rest but encrypts in transit automatically.

C Snowflake encrypts data at rest and in transit by default without user configuration.

D Snowflake does not support encryption for data in transit.

💡 Hint

Think about default security features in cloud services.

Snowflake automatically encrypts all data stored and moving through its system, enhancing security without extra user steps.

Cost management in Snowflake vs traditional data warehouses

What is a best practice for controlling costs in Snowflake that differs from traditional data warehouses?

A Pause or resize virtual warehouses when not in use to save compute costs.

B Buy fixed hardware upfront to reduce long-term expenses.

C Run all queries on a single large cluster to maximize resource use.

D Store all data in multiple copies to improve query speed.

💡 Hint

Think about how cloud resources can be managed dynamically.

Snowflake allows pausing compute resources when idle, unlike traditional warehouses that run on fixed hardware, helping reduce costs.

❓ Architecture

Impact of Snowflake's multi-cluster shared data architecture on workload isolation

How does Snowflake's multi-cluster shared data architecture improve workload isolation compared to traditional data warehouses?

A It forces all workloads to share a single compute cluster, increasing resource contention.

B It allows multiple independent compute clusters to access the same data without interfering with each other.

C It duplicates data for each cluster, increasing storage costs significantly.

D It requires manual data partitioning to separate workloads.

💡 Hint

Consider how Snowflake handles multiple compute clusters accessing data.

Snowflake's architecture lets many compute clusters run queries on the same data simultaneously without slowing each other down, unlike traditional warehouses.
