SNOW-CAD Practice Test 31 — 15 Questions

Question 1

Match each ServiceNow portal widget property to its purpose.

Accepted Answer

Name: A unique identifier used to reference the widget in code. The correct matches are: Name as a unique identifier used in code, ID as the system-assigned sys_id, Roles as access control, and Filter Condition as display condition. Common confusions include swapping Name and ID or mixing Roles with Filter Condition.

Answer

Name: The unique system identifier assigned automatically

Answer

Roles: A condition that determines when the widget is displayed

Question 2

A ServiceNow instance needs to expose a REST API endpoint for external applications to query incident data. The developer creates a Scripted REST API and needs to ensure that only authorized applications can access it. Which THREE methods can be used to secure the Scripted REST API?

Accepted Answer

Require the request to include a valid ServiceNow username and password (Basic Authentication). ServiceNow supports HTTP Basic Authentication, which requires the request to include a valid ServiceNow username and password in the Authorization header. This is a standard method for securing Scripted REST APIs, as the platform validates credentials against its user table before processing the request.

Answer

Require a valid SAML 2.0 assertion in the request body

Answer

Require that the request originates from an IP address within a specified LDAP directory

Question 3

Which TWO of the following are valid ways to reference a sys_id of a record in a business rule? (Choose two.)

Accepted Answer

current.getUniqueValue(). Options B, C, and E are all valid ways to reference the sys_id of a record in a business rule. Option B uses the `getUniqueValue()` method, which returns the sys_id even for new unsaved records. Option C uses `current.get('sys_id')` to retrieve the sys_id field value. Option E directly accesses the `sys_id` field via dot notation. All three methods correctly return the unique identifier of the current record.

Answer

current.number

Answer

current.getRow()

Question 4

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?

Accepted Answer

Use $uibModal.open to create a modal with a custom template. Service Portal widgets use AngularJS, and the standard way to open a modal with a custom template (such as a record producer form) is via `$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.

Answer

Use $scope.$broadcast to trigger a modal event

Answer

Use spModal.open with the record producer sys_id

Answer

Use window.open to open the record producer URL

Question 5

Refer to the exhibit. A Business Rule in the same scope calls this script include using 'var total = new MyUtils().getTotal("invoice", "state=paid");' but gets '0' even though there are records. What is the most likely cause?

Accepted Answer

The 'amount' field is not numeric in the invoice table.. The Business Rule calls `getTotal` which uses `GlideAggregate` to sum the `amount` field. If the `amount` field is not numeric (e.g., it is a string or another non-numeric type), `GlideAggregate.addAggregate('SUM', 'amount')` will return `0` because it cannot perform a numeric aggregation on non-numeric data. This matches option B.

Answer

The getTotal method is not properly defined.

Answer

The GlideAggregate query syntax is incorrect.

Answer

The script include is not accessible from the Business Rule's scope.

Question 6

A multinational corporation uses a single ServiceNow instance for IT service management. The ServiceNow portal serves thousands of users across multiple departments (HR, Finance, IT, Legal). Each department requires a customized portal experience: specific branding, tailored service catalog, and unique knowledge bases. The current implementation uses a single portal with multiple widgets that conditionally display content based on user group membership. Users have reported slow page loads and inconsistent styling across departments. The ServiceNow administrator must redesign the portal architecture to improve performance and maintainability while accommodating each department's requirements. Which approach should the administrator take?

Accepted Answer

Maintain a single portal but leverage ServiceNow's branding records and theme variants to apply department-specific styling; optimize widgets with client-side caching and lazy loading.. By maintaining a single portal and using ServiceNow's branding records and theme variants, the administrator can apply department-specific styling centrally without fragmentation. Optimizing widgets with client-side caching and lazy loading addresses performance issues. Option B is incorrect because creating separate portals per department leads to significant maintenance overhead and configuration fragmentation. Option C is incorrect because standardizing without customization ignores departmental requirements, resulting in poor user experience. Option D is incorrect because extensive client scripts for styling and content are inefficient, difficult to maintain, and still degrade performance.

Answer

Create a separate portal for each department, each with its own theme and set of widgets to fully isolate customizations.

Answer

Standardize all departments onto a single, simple portal with no customizations to reduce complexity and improve load times.

Answer

Keep one portal with a single theme and use extensive client scripts to alter styling and content based on the user's department.

Question 7

When creating a custom table to extend an existing table, which TWO considerations should be evaluated to ensure optimal performance and maintainability? (Choose two.)

Accepted Answer

The number of records in the parent table may impact query performance when retrieving child records. Options D and E are correct. When extending a table, the number of records in the parent table can impact query performance when retrieving child records because child tables inherit the parent table's data, and queries may need to scan the parent table as well. Adding too many fields to an extended table can degrade performance (more data to store and process) and increase complexity (harder to maintain relationships and ACLs). Option A is incorrect because while ServiceNow suggests a naming convention with 'u_' for custom tables, it is not a strict requirement for performance or maintainability. Option B is incorrect because the table should be created in the same scope as the application it belongs to, not necessarily global scope. Option C is incorrect because a reference field back to the parent table is not required; the table extension itself establishes the relationship via inheritance.

Answer

The table must have a unique name starting with 'u_'

Answer

The table should be created in the global scope to ensure universal access

Answer

The table must have a reference field back to the parent table

Question 8

Which THREE conditions must be met for a user to successfully see a record in a ServiceNow list view?

Accepted Answer

The user has read permission on the table via an ACL.. ServiceNow uses Access Control Lists (ACLs) to enforce read permissions on tables. Without a read ACL that evaluates to true for the user, the system will not display any records from that table in a list view, regardless of other conditions.

Answer

The user has write permission on the table.

Answer

The user has configured a personalized list view for the table.

Question 9

A ServiceNow developer is integrating with an external system using a REST message. The external system requires a custom header 'X-API-Key' to be included in every request. Where should the developer configure this header to ensure it is automatically included in all REST messages that call this endpoint?

Accepted Answer

In the 'HTTP Headers' tab of the REST message definition. The 'HTTP Headers' tab in a REST message definition allows you to define custom headers that are automatically included in every request sent to that endpoint. This is the standard location for headers like 'X-API-Key' that must accompany all calls, as they are part of the HTTP request metadata, not query parameters or authentication credentials.

Answer

In the 'Query Parameters' tab of the REST message definition

Answer

In the 'Authentication Profile' associated with the REST message

Answer

In the Scripted REST API used to create the endpoint

Question 10

A developer is building a custom application in ServiceNow Studio. The application requires a table that stores incident-like records but with additional custom fields. The developer wants to leverage existing functionality such as assignment rules, escalation, and SLA tracking. Which approach should the developer take?

Accepted Answer

Extend the Incident table and add custom fields to the extended table.. Extending the Incident table (Option A) is correct because it allows the developer to inherit all existing Incident functionality—such as assignment rules, escalation, and SLA tracking—while adding custom fields. In ServiceNow, table extension creates a child table that inherits all business rules, ACLs, and workflows from the parent, ensuring the custom application leverages the full Incident lifecycle without reimplementation.

Answer

Clone the Incident table and rename it, then modify the clone.

Answer

Create a new table from scratch and manually add all necessary fields and business rules.

Answer

Use the Configuration Management Database (CMDB) to store the records.

Question 11

A developer implemented an ACL to restrict read access on the 'incident' table. The condition script checks if the user is a member of the 'incident_manager' group. However, users who are not in the group are still able to see incidents. What is the most likely reason?

Accepted Answer

There is another ACL with a lower order that grants read access to all users, and the evaluation never reaches the scripted ACL.. ACLs in ServiceNow are evaluated in order of their 'Order' field (lower numbers first). If a lower-order ACL grants read access to all users, the evaluation stops at that ACL and never reaches the scripted ACL that restricts access to the 'incident_manager' group. This is the most common reason for an ACL appearing to not work — a broader, higher-priority ACL is allowing access before the restrictive one is evaluated.

Answer

The ACL is cached and users need to log out and back in for changes to take effect.

Answer

The condition script returns 'true' for users in the group but does not return 'false' for others, so the ACL defaults to 'no decision' and access is allowed.

Answer

The ACL is set to 'Inactive' so it does not apply, leaving access open.

Question 12

A new custom table is being created in ServiceNow. Which two attributes must be defined during table creation? (Choose two.)

Accepted Answer

Table label. The table label (A) is the human-readable name displayed in the ServiceNow UI, such as in lists and forms, and is required for user interaction. The table name (E) is the system name used internally in the database (e.g., 'u_custom_table'), and it must be unique within the instance. Both are mandatory fields when creating a new custom table in ServiceNow.

Answer

Access control rules

Answer

Extensible checkbox

Answer

Application scope

Question 14

A Script Include is defined as 'Scoped' and has 'Accessible from' set to 'All applications'. It contains a function that uses 'gs.getUser()'. When the Script Include is called from a Business Rule in a different application scope, what is the result?

Accepted Answer

The function runs successfully and gs.getUser() returns the current user from the caller's session.. A Script Include defined as 'Scoped' with 'Accessible from' set to 'All applications' is explicitly made available to other application scopes. When called from a Business Rule in a different scope, the function executes in the context of the caller's session, so `gs.getUser()` returns the current user from the caller's session, not from the Script Include's own scope. This behavior is governed by the scoping rules that allow cross-application access when the property is set accordingly.

Answer

An error occurs because scoped Script Includes cannot be called from other applications.

Answer

The function runs but gs.getUser() returns the user from the Script Include's application scope, not the caller.

Answer

The function runs but returns null because gs is not available in scoped applications.

Question 15

A ServiceNow instance has a custom application for managing IT assets. The application uses a custom table 'u_asset' with fields: u_asset_tag (string), u_model (string), u_assignee (reference to sys_user), u_status (choice: In Use, In Stock, Retired). The application requires that when an asset is retired, the assignee field must be cleared. The developer created a Business Rule on the 'u_asset' table that runs before update. The script checks if the status changes to 'Retired' and sets the assignee to empty. However, the assignee is not being cleared when the status is changed to 'Retired'. The Business Rule is active and runs before update. What is the most likely cause?

Accepted Answer

The script sets the field using 'current.u_assignee = null;' instead of 'current.setValue("u_assignee", "");'.. In ServiceNow Business Rules, setting a field to null using direct assignment (e.g., current.u_assignee = null) does not trigger the platform's update logic; the change is not persisted to the database. The correct method is to use current.setValue('u_assignee', '') which properly marks the field for update and clears the reference.

Answer

The Business Rule is set to run after the record is saved, so changes are overwritten.

Answer

The condition 'current.u_status.changesTo("Retired")' is incorrect.

Answer

The Business Rule runs after update instead of before update.
