- A
The Department table is empty
Why wrong: If the department table is empty, getDepartment() would return null, but the error is specifically for some users, not all.
- B
The script uses incorrect dot-walking syntax; use getValue('department') instead
Why wrong: The dot-walking syntax is correct; gs.getUser().getDepartment().getName() is valid GlideRecord dot-walking.
- C
The user table does not have a department reference field
Why wrong: The sys_user table has a department reference field by default.
- D
Some users do not have a department assigned, and the script does not check for null
When getDepartment() returns null, calling getName() on null causes a NullPointerException. The solution is to add a null check before calling getName().
SNOW-CAD Creating and customizing tables and data Practice Question
This SNOW-CAD practice question tests your understanding of creating and customizing tables and 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.
A developer writes a script to display the department name of the caller on a custom form. The script uses: gs.getUser().getDepartment().getName(). However, the script throws a null pointer exception for some users. Which is the most likely cause and solution?
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 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
Some users do not have a department assigned, and the script does not check for null
Option D is correct because the NullPointerException suggests that getDepartment() returned null for users without a department. Option A is wrong because the script is syntactically correct. Option B is wrong because reference exists. Option C is wrong because department records exist.
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.
