SNOW-CSA UI, Navigation and Forms Practice Question
Which TWO methods allow an administrator to make a field read-only on a form? (Choose two.)
⚠ Common exam trap
Test-takers frequently confuse ACLs (which control write access at the data layer) with UI policies (which control field editability at the presentation layer), leading them to incorrectly select option B as a method to make a field read-only on a form.

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
✓
Create a UI policy that sets the field to read-only when a condition is true
A UI policy can dynamically set a field to read-only based on a specified condition, such as a particular state or value. This allows administrators to control field editability at runtime without permanently altering the field's definition. Option D is correct because setting the 'Read only' attribute in the dictionary entry makes the field read-only globally across all forms and views, providing a static, system-wide restriction.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure the form layout to hide the field
Why it's wrong here
Hiding removes it, not make read-only.
- ✗
Create an ACL that denies write access
Why it's wrong here
ACL would prevent writing but the field may still appear editable.
- ✓
Create a UI policy that sets the field to read-only when a condition is true
Why this is correct
UI policy can change state dynamically.
- ✓
Set the field attribute to 'Read only' in dictionary entry
Why this is correct
This forces the field to be read-only always.
- ✗
Add the field to a related list
Why it's wrong here
Related lists are for related records, not field state.
