SMD is a smallfile locally managed tablespace with manual segment space management. The SH user receives the following error while inserting data into the sales table: Which three actions can be…

While altering a data file to grow automatically is a valid configuration for future space management, 'resizing' (Option D) is a more direct and immediate action to increase the current available space for an existing file to address an immediate error.

Adding a new data file provides additional physical space to the tablespace, but if the issue is internal fragmentation due to manual segment space management (Option C), or a user's quota (Option E), or the limit of an *existing* data file (Option D), then simply adding a new file might not be the most direct solution.

Changing the segment space management from manual to automatic (ASSM) improves space utilization, reduces fragmentation, and often resolves 'unable to extend' errors by efficiently managing free space within segments.

If an existing data file has reached its current size limit or its autoextend maximum, resizing it to a larger value provides more physical storage space for the tablespace, allowing further data insertion.

If the SH user's allocated space quota on the SMD tablespace has been exhausted, increasing or setting an unlimited quota will allow the user to allocate more segments and insert data.
