SNOW-CSA Database Administration and CMDB Practice Question
This SNOW-CSA practice question tests your understanding of database administration and cmdb. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
You are a ServiceNow administrator for a healthcare organization. The CMDB contains sensitive patient data under strict compliance rules. You need to ensure that only authorized users can view the full details of certain CIs, while still allowing change management to reference the CIs. What is the best practice to achieve this?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Access Controls (ACLs) to restrict read access to the sensitive CI records.
Access Controls (ACLs) are the correct mechanism to restrict read access to sensitive CI records while still allowing Change Management to reference them. ACLs can be configured to grant read access only to authorized users or roles, and the cmdb_ci table or specific CI records can be targeted. This ensures compliance with data privacy rules without removing the CIs from the CMDB or breaking downstream processes like change requests that need to link to those CIs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Move the sensitive CIs to a separate CMDB instance.
Why it's wrong here
Separate instances add complexity and cost; not necessary for access control.
✓
Use Access Controls (ACLs) to restrict read access to the sensitive CI records.
Why this is correct
ACLs can grant selective read access, ensuring only authorized users see sensitive details.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Encrypt the fields containing sensitive data.
Why it's wrong here
Encryption protects data at rest but does not control who can view it in the application.
✗
Remove the sensitive CIs from the CMDB and maintain them externally.
Why it's wrong here
Removing CIs defeats the purpose of a unified CMDB and complicates change management.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse encryption with access control, assuming that encrypting sensitive fields prevents unauthorized viewing, but encryption in ServiceNow does not enforce read permissions—it only protects data at rest, and users with read access can still decrypt and view the data unless ACLs are applied.
Detailed technical explanation
How to think about this question
ServiceNow ACLs operate at the table, record, or field level using conditions and scripts to evaluate user roles, groups, or criteria. For CMDB data, you can create a read ACL on the cmdb_ci table with a condition like 'sys_class_name == sensitive_class' and grant access only to specific roles (e.g., 'cmdb_sensitive_viewer'), while the 'cmdb_read' role or 'change_manager' role can still reference the CI via sys_id without viewing restricted fields. This approach leverages the platform's role-based access control (RBAC) and avoids data duplication or external dependencies.
KKey Concepts to Remember

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
