ServiceNow ACLs (Access Control Lists) determine whether a user can perform an operation (read, write, create, delete, etc.) on a table, record, or field. When an ACL includes multiple types of checks, the platform evaluates them in a defined sequence. ServiceNow documentation describes permission evaluation using rule types and indicates that Role checks are evaluated first, followed by additional rule criteria such as conditions, and finally scripts when present. This order matters for both security and performance. Role evaluation is typically fastest and can short-circuit further checks. If the user does not meet the role requirement, the platform does not need to evaluate the condition or run a script. Conditions are then evaluated to confirm record-based or context-based requirements. If the ACL still requires deeper logic beyond roles and conditions, a script can be executed last to decide access (often setting an answer value or returning true/false depending on the ACL type). Therefore, among the provided choices, the correct sequence is Roles → Conditions → Script.

In ServiceNow, extending a table means creating a new table (child class) that inherits properties from an existing table (parent class). This inheritance includes fields, business logic, and other configurations, allowing for efficient reuse and customization.

Key Points:

Field Inheritance: The child table inherits all fields from the parent table. For example, if you extend the Task table, your new table will include fields like "short_description" and "priority."

Business Logic Inheritance: The child table also inherits business rules, client scripts, and other logic defined on the parent table, ensuring consistent behavior across related tables.

Access Controls: Access controls are not ignored; instead, the child table inherits the parent table's access controls. However, you can define additional access controls specific to the child table as needed.

Customization: While the child table inherits many properties, you can add new fields, scripts, and behaviors to tailor it to specific requirements without affecting the parent table.

ServiceNow is optimized for building applications that manage structured data in tables and provide consistent user experiences through lists and forms. A core reason to develop on the platform is when the solution naturally fits the record-based model: users create, review, and update records through forms, and those records drive reporting, auditing, and process automation. That makes option C a direct match to how ServiceNow applications are designed and delivered. Another primary platform strength is workflow automation, including Flow Designer, approvals, task orchestration, notifications, and integration actions that coordinate work across teams and systems. If the solution requires repeatable, governed process automation, option D aligns with the platform’s purpose and capabilities. In contrast, “multimedia features” is not a platform driver for application development; while media can be displayed, it is not the typical reason to choose ServiceNow. Similarly, requiring low-level programming libraries is generally a mismatch, since ServiceNow development focuses on platform APIs and configuration patterns rather than direct access to low-level system libraries.

From the list below, the following is a reason an application might not be a good fit with ServiceNow:

Requires “as-is” use of low-level programming libraries. This is the correct answer because ServiceNow is a high-level platform that abstracts away the low-level details of the underlying infrastructure and technology stack. ServiceNow provides a rich set of APIs, tools, and features that allow users to develop applications without coding or with minimal coding. However, ServiceNow does not support the direct

The following are debugging strategies for client-side scripts, which run in the web browser and manipulate the user interface:

g_form.addInfoMessage(). This is a client-side API that displays an information message at the top of the form.

Field Watcher. This is a debugging tool that displays the current and previous values of one or more fields on a form.

jslog(). This is a client-side API that writes a message to the browser console.

The following is not a debugging strategy for client-side scripts, but for server-side scripts, which run on the ServiceNow platform and manipulate the database:

gs.log(). This is a server-side API that writes a message to the system log. References: Client-Side Scripting APIs, Debugging Client Scripts

The ServiceNow App Repository is a central repository for all scoped applications that are published by all ServiceNow customers. It enables ServiceNow customers to upload and distribute applications between their instances. It also provides entitlements and version control for the applications.
