SNOW-CSA UI, Navigation and Forms Practice Question
This SNOW-CSA practice question tests your understanding of ui, navigation and forms. 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.
Which THREE actions can be performed using UI policies? (Choose three.)
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
✓
Make a field read-only
Option B is correct because UI policies can set the 'read-only' attribute on a field, preventing users from modifying its value based on conditions. This is a core function of UI policies, which control field behavior on a form without requiring server-side scripting.
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
The trap here is that candidates often confuse UI policies with Data Policies or client scripts, assuming UI policies can set default values or create fields, but UI policies only modify existing field attributes on the client side.
Detailed technical explanation
How to think about this question
UI policies execute client-side JavaScript in the browser, manipulating field attributes like 'readonly', 'mandatory', and 'visible' through the g_form API. They run on form load and on field value changes, but they cannot create or destroy fields because the form structure is defined server-side by the dictionary and form layout. A common real-world scenario is hiding a field like 'State' when a certain category is selected, using a UI policy to set the 'visible' attribute to false.
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.
