SNOW-CSA Database Administration and CMDB Practice Question
An administrator wants to ensure that when a user deletes a CI, all its relationships are also deleted to maintain data integrity. What should the administrator configure?
⚠ Common exam trap
Many exam-takers choose a business rule (Option D) because it seems logical, but ServiceNow's native cascade delete on reference fields is the correct and simpler approach, avoiding the need for custom scripting.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A cascade delete rule on the relationship table
A cascade delete rule on the relationship table (sys_cmdb_rel_ci) ensures that when a CI is deleted, all associated relationship records are automatically removed. This maintains referential integrity in the CMDB without requiring custom scripting or manual cleanup.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A cascade delete rule on the relationship table
Why this is correct
Cascade delete rules are designed for this purpose.
- ✗
An ACL that denies delete unless relationships are removed first
Why it's wrong here
ACLs do not handle cascading deletes.
- ✗
A CMDB health rule that flags orphaned relationships
Why it's wrong here
Health rules only report issues, they do not automatically delete.
- ✗
A business rule on the CI table that deletes relationships on delete
Why it's wrong here
Possible but not the standard approach; cascade delete is built-in.
