SNOW-CAD Practice Test 28 — 15 Questions

Question 1

An administrator notices that a scheduled job, 'Update Asset Status', fails every night with a 'Script timeout' error. The job updates a large number of records in the Asset table. Which approach should the administrator take to resolve the timeout issue?

Accepted Answer

Rewrite the job to use GlideAggregate with query and update in bulk. Option D is correct because the script timeout error indicates that the scheduled job is taking too long to process individual record updates. Rewriting the job to use GlideAggregate with bulk update operations reduces the number of database round-trips and processes records in batches, which is the standard approach for handling large data sets in ServiceNow without hitting script timeout limits.

Answer

Add a business rule to run asynchronously for each update

Answer

Increase the timeout value in the scheduled job configuration

Answer

Split the job into multiple smaller jobs running sequentially

Question 2

A developer needs to create a service catalog variable that allows the user to select multiple values from a predefined list. Which variable type should be used?

Accepted Answer

Multiple Choice (Checkbox). Option D is correct because the Multiple Choice (Checkbox) variable type in ServiceNow allows users to select multiple values from a predefined list. This is the only variable type that supports multi-select behavior, which is required when a user needs to choose more than one option from a set of choices.

Answer

Single Line Text

Answer

Radio Button

Answer

Select Box

Question 3

A developer is creating a catalog item that requires a user to upload a file. Which variable type should be used?

Accepted Answer

Attachment. The Attachment variable type is specifically designed for file uploads in ServiceNow catalog items. It provides a built-in file picker and stores the uploaded file as an attachment on the requested record, enabling users to submit documents directly through the catalog form.

Answer

Multi Line Text

Answer

Single Line Text

Answer

Checkbox

Question 4

The Business Rule above runs on the 'incident' table. It is set to run 'before' update. What is the most likely issue with this script?

Accepted Answer

The script will cause a recursive loop because it updates incident records within a Business Rule that runs on the same table.. Option C is correct because updating the same table (incident) within a 'before update' Business Rule that runs on that table creates a recursive loop. Each time the script calls gr.update() on an incident record, it triggers the same Business Rule again, leading to infinite recursion until the system enforces a governor limit or stack overflow. ServiceNow detects and prevents such loops by throwing an error, but the design is fundamentally flawed.

Answer

The script should use 'current' instead of 'gr' to update records.

Answer

The script has a syntax error: missing semicolon after the while loop.

Answer

The script does not commit the changes because it uses 'gr.update()' instead of 'current.update()'.

Question 5

Which THREE of the following are correct statements about Service Portal client controllers?

Accepted Answer

They can use AngularJS services like $http and $timeout.. Option A is correct because Service Portal client controllers are AngularJS controllers that run in the browser. They can use standard AngularJS services such as $http for making AJAX calls to external APIs or the instance, and $timeout for delaying execution, which are both injected as dependencies.

Answer

They run on the server and are called via server-side includes.

Answer

They must define a $scope variable explicitly to bind data to the template.

Question 6

A developer runs this widget server script and expects data.count to be the number of active incidents. However, the widget displays 'undefined' for data.count. What is the most likely cause?

Accepted Answer

The script is missing the function parameters (options, data) that provide the data object.. In ServiceNow widget server scripts, the function signature must include the parameters (options, data) to access the data object that is passed to the client script. Without these parameters, the data variable is undefined, causing data.count to display 'undefined'. The script likely defines the function without parameters or with incorrect ones, so the data object is not available.

Answer

The addQuery method syntax is incorrect; it should use a condition string.

Answer

The while loop uses next(); it should use hasNext() instead.

Answer

GlideRecord requires an initialize() call before query.

Question 7

A developer is creating a scoped application and needs to reference a global table (e.g., 'sys_user') from a business rule. Which TWO statements are true regarding cross-scope access?

Accepted Answer

To write to a global table, the application must be granted the 'global' scope or have appropriate ACLs.. Option C is correct because scoped applications operate within an access control framework that restricts direct writes to global tables. To write to a global table like 'sys_user', the application must either be granted the 'global' scope (which removes scoping restrictions) or have appropriate ACLs that explicitly allow the write operation. Without these, a scoped application's GlideRecord write will fail due to cross-scope access controls enforced by the ServiceNow platform.

Answer

Scoped applications can create records in global tables via GlideRecord without restrictions.

Answer

Scoped applications can call global script includes by default.

Answer

Scoped applications can update global tables without any additional configuration.

Question 8

An organization has a custom table 'u_incident_task' that extends 'task'. They need to allow users to create records in this table from the 'Incidents' module. The 'u_incident_task' table should appear as a related list on the incident form. However, the related list is not showing the 'New' button. What is the most likely cause?

Accepted Answer

There is no reference field on 'u_incident_task' pointing to the incident table. The 'New' button appears on a related list only when there is a reference field on the target table (u_incident_task) that points back to the source table (incident). Without this reference field, the platform cannot automatically populate the parent record's sys_id when creating a new child record, so it suppresses the 'New' button. This is a core requirement for related list creation in ServiceNow.

Answer

The table is in a different application scope

Answer

The table does not extend 'incident'

Answer

The user does not have the required role

Question 9

A developer created a UI Script and a Client Script as shown. Both scripts set urgency and impact to '1' when priority is '1'. However, when the priority is changed to '1' on an existing record, the urgency and impact fields do not update. What is the most likely cause?

Accepted Answer

The UI Script is not being called because it is not associated with any form or event. A UI Script is a reusable client-side script that must be explicitly called from a Client Script, UI Policy, or form event to execute. In this scenario, the UI Script is not associated with any form or event, so it never runs when the priority field changes. The Client Script alone cannot invoke the UI Script without a direct call, leaving the urgency and impact fields unupdated.

Answer

The priority field is not a choice field, so onChange does not fire

Answer

The Client Script function name is incorrect; it should be 'onChangePriority'

Answer

The g_form API is deprecated and no longer works

Question 10

A developer is creating a new table 'u_incident_custom' to extend the Incident table. Which TWO configurations will ensure that the new table inherits the correct behavior and displays in the application navigator?

Accepted Answer

Set 'Application' to the desired scope and check 'Display in application navigator'. Option A is correct because setting 'Application' to the desired scope ensures the table belongs to the correct application context, and checking 'Display in application navigator' makes the table visible in the application navigator menu. Option D is correct because setting 'Extends' to 'Incident' establishes the inheritance relationship, allowing the new table to inherit all fields, business rules, and behaviors from the Incident table, which itself extends Task.

Answer

Create a module pointing to the new table

Answer

Set 'Label' to 'Incident Custom'

Answer

Set 'Extends' to 'Task'

Question 11

Which TWO of the following are valid ways to create a Business Rule? (Choose two.)

Accepted Answer

Navigate to 'System Definition > Business Rules' and click 'New'.. Option B is correct because navigating to 'System Definition > Business Rules' and clicking 'New' is the standard module-based method for creating a Business Rule in ServiceNow. This path directly accesses the Business Rule table (sys_script) and opens a new record form, which is a valid and documented approach.

Answer

From the Business Rules list, right-click and select 'New'.

Answer

Type 'business_rule.do' in the navigator filter.

Answer

Create a Client Script and convert it to a Business Rule.

Question 12

Which THREE of the following are true about ACLs (Access Control Lists)? (Choose three.)

Accepted Answer

ACLs can include conditions that must be met for access.. ACLs (Access Control Lists) in ServiceNow are used to enforce security by specifying conditions that must be met for a user to access a record, field, or script. Option A is correct because an ACL defines a condition (typically a script or a set of conditions) that evaluates to true or false, and only when the condition is met is access granted or denied. This is the core mechanism of ServiceNow's role-based and condition-based access control.

Answer

ACLs are evaluated on the client side.

Answer

ACLs are only applicable to system tables.

Question 13

A Service Portal widget is not updating data on the page after the user clicks a button that calls a server-side function. The client controller uses $scope.server.get() to call the server. The server script updates a global variable in glideRecord and returns it. However, the widget view does not reflect the change. What is the most likely issue?

Accepted Answer

The client controller is not handling the promise returned by $scope.server.get(); the scope update should be inside the success callback.. Option C is correct because `$scope.server.get()` returns a promise, and the scope variables must be updated inside the `.then()` success callback to ensure the changes are applied after the asynchronous server response is received. Without handling the promise, the client controller executes the next line immediately, and the scope update happens before the server data is available, so the widget view never reflects the change.

Answer

The widget template is not bound to the correct scope variable.

Answer

The client controller should use $scope.server.update() instead of $scope.server.get().

Answer

The server script is not allowed to modify data from a widget server script.

Question 14

A company needs to automatically update the 'Assignment group' field on the Change Request table to 'Change Management' when the 'Category' field is set to 'Network'. Which type of business rule should be used?

Accepted Answer

Before business rule. A Before business rule (Option D) is correct because it runs before the record is saved to the database, allowing you to set the 'Assignment group' field value based on the 'Category' field before the insert or update operation completes. This ensures the assignment group is correctly populated in the same database transaction, avoiding the need for a separate update.

Answer

Display business rule

Answer

Async business rule

Answer

After business rule

Question 15

A developer needs to create a new table in ServiceNow to track project milestones. The table should have a reference field to the Project table and a date field for the milestone date. Which data type should be used for the reference field?

Accepted Answer

Reference. Option D is correct because in ServiceNow, a reference field is specifically designed to create a relationship between two tables by storing the sys_id of the referenced record. This allows the developer to link a project milestone record to a specific project record in the Project table, enabling dot-walking and data integrity through referential integrity constraints.

Answer

GlideRecord

Answer

Integer

Answer

String
