A Correct answer
Explanation

Teradata spool space is allocated dynamically from unused permanent disk space. Since the system has 100 GB of total space and 30 GB is used by data, 70 GB remains unused and available for spool space. Stated spool limits restrict individual consumption, but the total physical capacity available for spool queries is 70 GB.

AI explanation

To calculate the total available spool space for user queries, we need to subtract the amount of user data from the reserved spool space.

Given information:

  • Total permanent space = 100 GB
  • Reserved spool space = 50 GB
  • Current user data = 30 GB

To calculate the available spool space, we subtract the current user data from the reserved spool space: Available spool space = Reserved spool space - Current user data

Substituting the given values: Available spool space = 50 GB - 30 GB Available spool space = 20 GB

Therefore, the total available spool space for user queries is 20 GB.
