- A
Set the 'Asset Tag' field as mandatory
Why wrong: Mandatory forces a value, but users can still enter 'No asset tag'.
- B
Use a workflow to populate the field
Why wrong: Workflow is not designed for field defaults and adds complexity.
- C
Configure a default value for the 'Asset Tag' field
Why wrong: Configuring a default value only sets an initial value but does not prevent users from overwriting it with 'No asset tag'. It does not enforce data quality.
- D
Create a data policy that requires a pattern
A data policy with a pattern or condition script can reject entries that match disallowed values like 'No asset tag', proactively preventing incorrect data.
Question 226 of 520
CMDB Field Default Value: Preventing 'No Asset Tag'
This SNOW-CSA practice question tests your understanding of database administration and cmdb. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a data policy that requires a pattern
Option D is correct because a data policy can enforce that the 'Asset Tag' field does not contain the specific string 'No asset tag' by using a condition script. Default values only populate the field at creation but do not prevent users from manually entering unwanted values like 'No asset tag' later. A data policy with a pattern requirement can block such invalid entries, ensuring data integrity.
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

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap is that default values are often thought to solve all empty-field issues, but they do not block manually entered invalid values. Data policies are needed to enforce specific patterns or values.
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- 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 practitioner preparing for the SNOW-CSA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
