SNOW-CAD Base table (sys_object) Practice Question
A developer is creating a new custom table for tracking software licenses. The table must inherit the core fields (sys_id, sys_created_by, etc.) and support extensibility for future sub-tables. Which base table should be used?
⚠ Common exam trap
Candidates often mistake sys_db_object for the base record table, but it is a system table for table definitions, not data records. The correct base table is sys_object (the 'Base' table), which is not listed among the options.

Correct answer & explanation
✓
Create a new table that extends directly from sys_db_object
None of the provided options are correct. For a custom table that needs to inherit core system fields (sys_id, sys_created_by, etc.) and support future extensibility, the table should extend from the **Base table** (sys_object). The Base table provides the fundamental record structure and is the recommended starting point for custom tables not tied to specific functionality like tasks or CIs. Extending from sys_db_object (a meta-table for table definitions), cmdb_ci, Task, or cloning Incident all introduce unnecessary overhead or are architecturally incorrect.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the Configuration Item (cmdb_ci) table as a base
Why it's wrong here
Incorrect. The Configuration Item (cmdb_ci) table is designed for CMDB items and includes fields specific to configuration management, not for a generic license tracking table.
- ✓
Create a new table that extends directly from sys_db_object
Why this is correct
Incorrect. Extending from sys_db_object is wrong because sys_db_object is a meta table that holds definitions of all tables, not a data table. It does not provide core record fields.
- ✗
Extend from the Task table
Why it's wrong here
Incorrect. The Task table includes fields for workflow, assignments, and state management that are unnecessary for a simple license table and can cause confusion.
- ✗
Clone the Incident table and remove unnecessary fields
Why it's wrong here
Incorrect. Cloning the Incident table brings all its fields, business logic, and relationships, which is overkill and introduces unnecessary complexity.
