3 questions from the free diagnostic, with answers and explanations.

Question 1 · Snowflake AI Data Cloud Features and Architecture

Which three layers make up the Snowflake architecture?

  1. Database storage, compute (virtual warehouses) and cloud services
  2. Data lake, data warehouse and data mart, each billed separately
  3. Ingestion, transformation and reporting, run on shared servers
  4. Bronze, silver and gold tables, stored in separate accounts
Show answer

Answer: A (Database storage, compute (virtual warehouses) and cloud services)

Storage, compute and cloud services are separate layers that scale independently; cloud services handles metadata, optimization, security and transactions.

Question 2 · Snowflake AI Data Cloud Features and Architecture

A virtual warehouse resumes, runs one query for 10 seconds and then suspends. How is its compute billed for this run?

  1. For 60 seconds, the minimum each time a warehouse starts, then per second
  2. For 10 seconds only, since billing is always strictly per second of runtime
  3. For a full hour, since warehouses are billed in hourly blocks
  4. Not at all, since queries under a minute are free of charge
Show answer

Answer: A (For 60 seconds, the minimum each time a warehouse starts, then per second)

Warehouse credits are billed per second with a 60-second minimum each time the warehouse starts or resumes.

Question 3 · Snowflake AI Data Cloud Features and Architecture

A team stages intermediate data that can be rebuilt from source and wants to avoid Fail-safe storage costs, while keeping the table across sessions. Which table type fits?

  1. A transient table
  2. A temporary table
  3. A permanent table
  4. An external table
Show answer

Answer: A (A transient table)

Transient tables persist across sessions but have no Fail-safe and at most 1 day of Time Travel; temporary tables disappear when the session ends.
