    Designing and Creating an Application

    Before any script runs, you decide whether ServiceNow fits the problem, how the tables relate, and which scope owns the work. Those choices are tested directly and shape every later domain.

    Inside this domain

    • Determine if an application is a good fit with ServiceNow
    • Design and implement a data model
    • Create modules
    • Use Application scope

    Watch for Inherit from the closest-looking table

    Application User Interface

    This domain tests whether you put logic in the right place: form layout or dictionary, client or server, UI policy or script. Most wrong answers here work, but run in the wrong layer.

    Inside this domain

    • Create, design, and customize forms
    • Add/Remove fields from forms and tables
    • Write, test, and debug client-side scripts for desktop
    • Write, test, and debug server-side scripts
    • and 1 more objectives

    Security and Restricting Access

    Security questions ask who can reach which application, record and field, and why. You need the access control evaluation rules and scope settings precise enough to predict the outcome.

    Inside this domain

    • Restrict access to applications and application modules
    • Manually and automatically create, test, and debug Access Controls
    • Use GlideSystem methods to script security
    • Use Application Scope to protect application artifacts

    Watch for Role passes, so access passes

    Application Automation

    Automation questions ask what should trigger work, where reusable logic lives, and how users hear about it. You choose between flows, events, scheduled jobs, script includes, notifications and reports.

    Inside this domain

    • Write, test, and debug Workflow and Flow Designer
    • Create and use Application Properties
    • Create Events, Scheduled Script Executions (Scheduled Jobs), and Utils (application) Script Includes
    • Send and receive email
    • and 1 more objectives

    Working with External Data

    Two objectives, both practical: load spreadsheet data cleanly through import sets, and call or test a REST service. The exam centers on coalesce, transform scripts and reading REST responses.

    Inside this domain

    • Import data in CSV or Excel format
    • Integrate to, including testing and debugging, an external data source using REST

    Managing Applications

    Once an application works, it must be shared, installed and changed safely by more than one developer. This domain tests installation paths, delegated development and Git source control.

    Inside this domain

    • Download and install applications
    • Use Delegated Development to manage source code and code review
    • Use the ServiceNow Git integration to manage source code

Practice questionDomain 1: Designing and Creating an Application

A facilities team wants an application to track equipment loan requests. Each request must be assigned to a group, move through states, record work notes and support SLAs. Which data-model choice meets these needs with the least custom work?

One trap from every domain

The answer that looks right, and the clue that gives it away.

  • Domain 1

    Inherit from the closest-looking table

    Clue The scenario describes a new, non-IT process that needs assignment, states or SLAs.

  • Domain 2

    Client-side check as enforcement

    Clue The requirement says the rule must apply however records are created or updated.

  • Domain 3

    Role passes, so access passes

    Clue The access control in the scenario has a condition or script in addition to a role.

  • Domain 4

    Business rule for time

    Clue The trigger is a date or time being reached, not a user or integration updating the record.

  • Domain 5

    Duplicates blamed on the file

    Clue The same rows appear twice after a repeated import and a unique identifier column exists.

  • Domain 6

    Admin for a contractor

    Clue The scenario stresses limiting the person to one application or certain file types.
