SNOW-CAD Practice Question: Automating application logic with business rules and scripts
This SNOW-CAD practice question tests your understanding of automating application logic with business rules and scripts. 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
Business Rule: "Update CI on Incident Update"
Table: Incident
When: After update
Script:
(function executeRule(current, previous /*null when async*/) {
if (current.state.changesTo('Resolved')) {
var ci = current.cmdb_ci;
if (ci) {
var gr = new GlideRecord('cmdb_ci_server');
gr.get(ci);
gr.operational_status = 'In Use';
gr.update();
}
}
})(current, previous);
Refer to the exhibit. The business rule is intended to update the CI's operational status when an incident is resolved. However, the CI is not being updated. What is the most likely reason?
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.
Business Rule: "Update CI on Incident Update"
Table: Incident
When: After update
Script:
(function executeRule(current, previous /*null when async*/) {
if (current.state.changesTo('Resolved')) {
var ci = current.cmdb_ci;
if (ci) {
var gr = new GlideRecord('cmdb_ci_server');
gr.get(ci);
gr.operational_status = 'In Use';
gr.update();
}
}
})(current, previous);
A
The business rule runs after the record is saved, so changes to the CI are not saved
Why wrong: After rules can update other records; changes are saved.
B
The script does not include a condition to check if the CI belongs to the cmdb_ci_server table
If the CI is not a server, the GlideRecord may fail to find it.
C
The business rule runs synchronously, so it cannot update another record
Why wrong: Synchronous rules can update other records.
D
The script uses gr.update() without checking if the CI record exists
Why wrong: While true, the most likely cause is the table mismatch.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The script does not include a condition to check if the CI belongs to the cmdb_ci_server table
The script assumes the CI record is of type 'cmdb_ci_server'. If the CI is a different class (e.g., cmdb_ci_router), the GlideRecord will not find it. Option A is incorrect because after business rules can update other records. Option B is not the root cause. Option C is false because synchronous rules can update other records.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
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.
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.
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.
