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.
Exhibit
```javascript
var gr = new GlideRecord('cmdb_ci');
gr.addQuery('sys_class_name', 'cmdb_ci_server');
gr.addQuery('u_environment', 'production');
gr.setLimit(1);
gr.orderByDesc('sys_updated_on');
gr.query();
if(gr.next()) {
gs.info(gr.getValue('name'));
}
```
Refer to the exhibit. The script runs but no output is produced. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The field 'u_environment' does not exist on records with sys_class_name='cmdb_ci_server'.
Option D is correct because the script uses `getValue('u_environment')` on a GlideRecord query for `cmdb_ci` with `sys_class_name='cmdb_ci_server'`. If the field `u_environment` does not exist on that table or class, `getValue` returns null, and the `gs.print` statement outputs nothing (or an empty string). The script runs without error, but no output is produced because the field is missing, not because the query returns zero rows.
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.
✗
The table 'cmdb_ci' has no records with sys_class_name='cmdb_ci_server'.
Why it's wrong here
There could be servers but the query might still fail due to field issues.
✗
The orderByDesc method is misspelled (should be orderByDescending).
Why it's wrong here
orderByDesc is a valid GlideRecord method.
✗
The script lacks point number of rows (no rows with condition).
Why it's wrong here
This is a restatement, not a root cause.
✓
The field 'u_environment' does not exist on records with sys_class_name='cmdb_ci_server'.
Why this is correct
A missing field causes the query to return no results.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume 'no output' means 'no records matched the query' (Option A), but the real issue is that the script runs successfully yet prints nothing because the field being accessed does not exist on the queried records.
Detailed technical explanation
How to think about this question
In ServiceNow, `getValue()` returns the value of a field as a string, or null if the field does not exist on the table or is not accessible to the current scope. The `sys_class_name` filter restricts records to a specific class in the CMDB hierarchy; if `u_environment` is a custom field that was never added to the `cmdb_ci_server` form or table schema, `getValue` silently returns null. This differs from a database error — ServiceNow does not throw an exception for missing fields; it simply returns null, which can lead to silent failures in scripts that assume the field exists.
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.

What is the correct answer to this question?
The correct answer is: The field 'u_environment' does not exist on records with sys_class_name='cmdb_ci_server'. — Option D is correct because the script uses `getValue('u_environment')` on a GlideRecord query for `cmdb_ci` with `sys_class_name='cmdb_ci_server'`. If the field `u_environment` does not exist on that table or class, `getValue` returns null, and the `gs.print` statement outputs nothing (or an empty string).
