Practice questionDomain 1: Snowflake AI Data Cloud Features and Architecture

A data team must run a resource-intensive data science workload at the same time as a separate business reporting workload, and neither should slow the other down. Both need access to the same data. What is the BEST approach in Snowflake?

One trap from every domain

The answer that looks right, and the clue that gives it away.

  • Domain 1

    Resize instead of isolate

    Clue Two workloads must run at once without competing.

  • Domain 2

    Resize for repeat queries

    Clue The same query runs repeatedly on unchanged data.

  • Domain 3

    Fail-safe for recent recovery

    Clue The user needs to restore recent data themselves.

  • Domain 4

    COPY INTO for continuous arrival

    Clue Files arrive continuously and should load automatically.

  • Domain 5

    Share with a non-customer via direct share

    Clue The consumer is not a Snowflake customer.
