Question 193 of 504
SNOW-CSA UI, Navigation and Forms Practice Question
A user reports that a form loads slowly. The administrator notices several UI Policies and Client Scripts are running on the form. What is the best practice to improve form performance?
⚠ Common exam trap
Watch out — candidates often assume 'fewer scripts' always means better performance, but ServiceNow tests the understanding that conditional execution (not just reducing count) is the correct optimization strategy.
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
✓
Set the UI Policy and Client Script to run only when needed using conditions
UI Policies and Client Scripts execute client-side in the browser, and their conditions determine whether they run on a given form. By setting them to run only when needed (e.g., based on a specific field value or form load event), you reduce unnecessary JavaScript execution, which directly improves form load and interaction performance. This is a best practice in ServiceNow to avoid processing scripts that are irrelevant to the current context.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use only one UI Policy per form
Why it's wrong here
Multiple UI Policies are acceptable if they are conditional; this is not a standard best practice.
- ✓
Set the UI Policy and Client Script to run only when needed using conditions
Why this is correct
Conditional execution reduces unnecessary client scripts, speeding up form loading.
- ✗
Disable all client-side scripts
Why it's wrong here
This would break functionality; performance tuning should be selective.
- ✗
Convert all UI Policies to Business Rules
Why it's wrong here
Business Rules do not reduce client-side processing; they run on the server.
