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.
A ServiceNow CSA is tasked with ensuring that all CIs in the CMDB have an accurate 'Asset Tag' field. Some records show 'No asset tag' as a value. Which method can prevent this in the future?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a default value for the 'Asset Tag' field
Option C is correct because configuring a default value for the 'Asset Tag' field ensures that when a new CI is created without an explicit asset tag, the system automatically populates the field with a predefined value (e.g., 'No asset tag' or a placeholder). This prevents the field from being left empty or showing an unintended value, as the default is applied at record creation. In ServiceNow, default values are set in the dictionary configuration for the field, making this a simple and effective preventive measure.
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.
✗
Set the 'Asset Tag' field as mandatory
Why it's wrong here
Mandatory forces a value, but users can still enter 'No asset tag'.
✗
Use a workflow to populate the field
Why it's wrong here
Workflow is not designed for field defaults and adds complexity.
✓
Configure a default value for the 'Asset Tag' field
Why this is correct
A default value can be blank or a meaningful value, preventing placeholder entries.

✗
Create a data policy that requires a pattern
Why it's wrong here
Data policy can enforce format but not prevent a specific string.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'mandatory' with 'preventing incorrect values,' but mandatory only ensures a value is entered, not that it is the correct or intended value, while a default value proactively sets the field to a desired state.
Detailed technical explanation
How to think about this question
In ServiceNow, default values are defined in the sys_dictionary record for a field, using the 'Default value' attribute. When a new record is created, the platform applies this default before any business rules or UI policies run, ensuring consistency. A real-world scenario is when asset tags are assigned by an external system; a default value like 'Pending' can be used until the external system updates the field, preventing manual errors.

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.
