A virtual warehouse is created using the following command:

Create warehouse my_WH with -
warehouse_size = MEDIUM

What action should be taken to address this situation?

  1. Increase the warehouse size from Medium to 2XL.
  2. Increase the value for the parameter MAX_CONCURRENCY_LEVEL.
  3. Configure the warehouse to a multi-cluster warehouse.
  4. Lower the value of the parameter STATEMENT_QUEUED_TIMEOUT_IN_SECONDS.

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.
