What do the terms scale up and scale out refer to in Snowflake? (Choose two.)

  1. Scaling out adds clusters of the same size to a virtual warehouse to handle more concurrent queries.
  2. Scaling out adds clusters of varying sizes to a virtual warehouse.
  3. Scaling out adds additional database servers to an existing running cluster to handle more concurrent queries.
  4. Snowflake recommends using both scaling up and scaling out to handle more concurrent queries.
  5. Scaling up resizes a virtual warehouse so it can handle more complex workloads.
  6. Scaling up adds additional database servers to an existing running cluster to handle larger workloads.

Answer(s): A,E

Question 104:

  • Correct answer: D) Multi-Terabyte (TB) Range

  • Brief explanation:
- clustering keys organize data into micro-partitions to improve pruning when queries filter on those columns. - The performance benefit is most significant for very large tables; for small tables the overhead of maintaining clustering outweighs gains. - Therefore, as a best practice, define clustering keys on tables at the TB scale.

Question 3:

  • False is the correct answer (Option B).

Why:
  • In Snowflake, a database is a metadata object that exists within a single Snowflake account. Accounts are isolated—there isn’t one database that lives in multiple accounts.
  • You can access data across accounts via data sharing or database replication, but these create separate database objects in the other accounts (e.g., a database in the consumer account created from a share), not a single shared database across accounts.

So a single database cannot exist in more than one Snowflake account.
