The answer is Business rules on the cmdb_ci table, along with Access Control Lists (ACLs) and CMDB Health Definitions with remediation tasks. Business rules enforce authorization by running server-side logic before a record is inserted, updated, or deleted, allowing you to validate or reject unauthorized CMDB changes at the database level. ACLs control read and write access to CI records based on user roles and conditions, while Health Definitions can trigger remediation tasks that automatically revert or flag unauthorized attribute modifications when a CI’s health score drops below a threshold. On the ServiceNow Certified System Administrator CSA exam, this question tests your understanding of the three distinct layers of CMDB change control: data-level rules, access-level security, and health-driven compliance. A common trap is to confuse Health Definitions with simple reporting—remember that remediation tasks are the enforcement mechanism. Memory tip: think “Rules, Rights, and Remediation” to recall Business Rules, ACLs, and Health Definitions as the trio for controlling CMDB changes.
SNOW-CSA Database Administration and CMDB Practice Question
This SNOW-CSA practice question tests your understanding of database administration and cmdb. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to ensure that only authorized changes to the CMDB are allowed. Which THREE of the following mechanisms can help enforce this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
CMDB Health Definitions with remediation tasks
Option B is correct because CMDB Health Definitions can include remediation tasks that automatically or manually enforce compliance by correcting unauthorized changes to CI attributes. These tasks are triggered when a health score falls below a threshold, ensuring that only authorized modifications persist in the CMDB.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
The Identification and Reconciliation Engine (IRE)
Why it's wrong here
IRE handles identification and reconciliation, not authorization.
✓
CMDB Health Definitions with remediation tasks
Why this is correct
Health rules can detect and correct unauthorized changes.

✗
Scheduled Discovery jobs
Why it's wrong here
Discovery is a source of changes, not a control mechanism.
✓
Access Control Lists (ACLs) on CMDB tables
Why this is correct
ACLs restrict who can read/write CMDB data.

Business rules on the cmdb_ci table
Why this is correct
Business rules can enforce data integrity and authorization logic.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the IRE's role in data reconciliation with change authorization, or assume that Discovery jobs inherently enforce change control, when in fact neither mechanism validates whether a change is authorized before applying it.
Detailed technical explanation
How to think about this question
Under the hood, CMDB Health Definitions use a scoring system based on rules that check CI attributes against expected values; remediation tasks can be configured to run a fix script or trigger a workflow when a violation is detected. This mechanism is part of the ServiceNow CMDB Health Dashboard, which relies on scheduled jobs to evaluate health scores and execute remediation actions, effectively acting as a post-change enforcement layer rather than a real-time authorization gate.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
