The answer is that the setLimit(10) method restricts the number of records returned by the GlideRecord query. When you call setLimit(10) on a GlideRecord object, it explicitly caps the result set to a maximum of 10 records, regardless of how many records actually match the query conditions. In this scenario, the script correctly queries for active priority 1 incidents, but because setLimit(10) is applied, only 10 of those incidents are returned, even though more exist in the database. On the ServiceNow Certified Application Developer CAD exam, this question tests your understanding of GlideRecord query limits and common pitfalls—many developers mistakenly assume the query itself is flawed or that setLimit affects date filtering. A frequent trap is confusing setLimit with setWindow, which controls pagination rather than a hard cap. Memory tip: think of setLimit as a bouncer at a club—no matter how many people are on the list, only the first 10 get in.
SNOW-CAD Working with Data Practice Question
This SNOW-CAD practice question tests your understanding of working with data. 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
var gr = new GlideRecord('incident');
gr.addQuery('active', true);
gr.addQuery('priority', '1');
gr.setLimit(10);
gr.query();
while(gr.next()) {
gs.info(gr.number);
}
Refer to the exhibit. A developer runs this script and notices it only returns 10 incidents even though there are more than 10 active priority 1 incidents. What is the reason?
var gr = new GlideRecord('incident');
gr.addQuery('active', true);
gr.addQuery('priority', '1');
gr.setLimit(10);
gr.query();
while(gr.next()) {
gs.info(gr.number);
}
A
The script only gets incidents from the current session.
Why wrong: Session does not affect query results.
B
The script only retrieves incidents created today.
Why wrong: No date filter is applied.
C
The incident table is not joined with any other table.
Why wrong: Joins are not causing the limit.
D
The setLimit(10) method limits the number of records returned.
setLimit restricts the GlideRecord query to 10 records.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The setLimit(10) method limits the number of records returned.
Option B is correct because setLimit(10) limits the result set to 10 records. Option A is wrong because the query is correct. Option C is wrong because setLimit does not restrict to today's records. Option D is wrong because there is no join.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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-CAD 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.
