The correct choice is to use $uibModal.open to create a modal with a custom template. This is the standard AngularJS approach within Service Portal because record producers are not native modal components; they require a custom template that embeds the record producer form, and $uibModal.open provides the necessary controller, template, and resolve data to control the modal’s behavior. On the ServiceNow Certified Application Developer CAD exam, this question tests your understanding of how Service Portal widgets leverage AngularJS UI Bootstrap, and a common trap is assuming a simple URL or sys_id parameter can open a record producer in a modal—it cannot, because the modal must be instantiated programmatically. Remember the memory tip: “Modal needs a template, not a parameter”—if you see an option that just passes a sys_id, it’s a distractor; the correct path always involves $uibModal.open with a custom template to render the record producer.
SNOW-CAD Designing interfaces and user experiences Practice Question
This SNOW-CAD practice question tests your understanding of designing interfaces and user experiences. 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 Service Portal widget displays a list of catalog items. Each catalog item should link to a record producer that opens in a modal dialog. Which approach should the developer use to open the modal?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use $uibModal.open to create a modal with a custom template
Option C is correct because Service Portal widgets use AngularJS, and the standard way to open a modal with a custom template (such as a record producer form) is via `$uibModal.open`. This method allows the developer to specify a controller, template, and resolve data, giving full control over the modal's behavior and content. Record producers are typically rendered inside a custom template, not directly via a sys_id parameter.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 $scope.$broadcast to trigger a modal event
Why it's wrong here
Broadcasting events doesn't open a modal; you need a modal service.
✗
Use spModal.open with the record producer sys_id
Why it's wrong here
spModal.open is not a standard ServiceNow API.
✓
Use $uibModal.open to create a modal with a custom template
Why this is correct
$uibModal is the Angular UI Bootstrap service for modals.

✗
Use window.open to open the record producer URL
Why it's wrong here
window.open opens a new window, not a modal.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ServiceNow often tests the distinction between Service Portal-specific utilities (`spModal`) and general AngularJS UI Bootstrap (`$uibModal`), leading candidates to incorrectly choose `spModal.open` for complex modals like record producers.
Detailed technical explanation
How to think about this question
Under the hood, `$uibModal.open` creates a modal instance using Angular UI Bootstrap's modal service, which compiles a template and instantiates a controller in a new child scope. For record producers, the developer typically passes the sys_id as a resolve parameter to the modal controller, which then uses `spUtil.get` or a GlideAjax call to fetch the producer's details and render the form. A subtle behavior is that the modal's scope is isolated, so data must be passed via resolve or `$scope.$close` to return results.

Real-world example
How this comes up in practice
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
