SNOW-CAD Practice Test 14 — 15 Questions

Question 1

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 2

A service desk manager wants to create a report that shows the number of incidents assigned to each support group over the past month. The manager wants the report to update automatically every week and be emailed to the team leads. The developer needs to implement this efficiently without creating custom tables or scheduled jobs. Which approach should the developer take?

Accepted Answer

Create a report using the 'Report' module and schedule it to run weekly with email delivery.. The correct option is C: creating a report with the 'Report' module and scheduling it to run weekly with email delivery. This approach directly satisfies the requirement for automatic weekly updates and email distribution to team leads, and it avoids custom tables or scheduled jobs as the scenario demands. The Report module natively supports aggregation of incidents by assignment group and built-in scheduling with email delivery, making it the most efficient solution. Option A is incorrect because a database view with a data export still requires external scheduling and does not natively email recipients. Option B is incorrect because it involves creating a scheduled job, which the scenario explicitly says to avoid. Option D is incorrect because it requires creating a custom table and a transform map, adding unnecessary complexity and violating the no-custom-tables constraint.

Answer

Create a database view that aggregates the data and schedule a data export.

Answer

Create a scheduled job that runs a report and emails the results.

Answer

Create a transform map to import the incident data into a custom table and then report.

Question 3

A developer needs to import user records from a CSV file. The CSV contains a field 'department' that should map to a reference field 'department' on the sys_user table. However, the CSV contains department names, not sys_ids. What is the best approach to map the department names to the correct sys_ids?

Accepted Answer

Use a transform script to query the department table and set the reference field.. When importing data with a reference field that contains display values (like department names) instead of sys_ids, a transform script is needed to query the referenced table (e.g., cmn_department) to find the matching sys_id and set the reference field. This is done in the 'onBefore' transform script, where you can use GlideRecord to look up the department by name and assign its sys_id to the target field.

Answer

Set a default value for the department field in the transform map.

Answer

Use a coalesce field mapping on the department field.

Answer

Add a reference qualifier to the department field in the target table.

Question 4

A developer is troubleshooting a UI policy that sets a field to mandatory when another field equals 'Yes'. The UI policy works on desktop but not on the mobile app. What is the most likely cause?

Accepted Answer

The UI policy is set to 'Run on desktop' only.. UI policies have a 'Run on desktop' and 'Run on mobile' checkbox. By default, a new UI policy is set to run on desktop only. If the developer did not explicitly check the 'Run on mobile' option, the policy will not execute on the mobile app, causing the mandatory behavior to be absent on mobile while working on desktop.

Answer

The UI policy is set to 'Run on mobile' but the script is incompatible.

Answer

The field is not available on the mobile form.

Answer

The mobile app uses a different table.

Question 5

Which THREE are true about Data Policies? (Choose three.)

Accepted Answer

They can be used to enforce field requirements.. Data Policies are server-side validation rules in ServiceNow that enforce data integrity before a record is written to the database. Option A is correct because Data Policies can enforce field requirements, such as making a field mandatory or read-only, on specified tables. Option B is correct because Data Policies can reference the current record's values to conditionally apply those requirements based on the data being submitted. Option D is correct because Data Policies can be applied to specific user roles, allowing different enforcement for different groups of users. Option C is incorrect because Data Policies can fire on insert and update, not insert only. Option E is incorrect because Data Policies run on the server side, not the client side only.

Answer

They can fire on insert only.

Answer

They run on the client side only.

Question 6

A business rule updates a field on the incident table after submission. However, the updated value is not displayed on the form when the record is opened again. What is the most likely cause?

Accepted Answer

A client script (onLoad) is setting the field back to its original value.. A client script (onLoad) that sets the field back to its original value is the most likely cause because onLoad scripts execute when the form loads, and if the script explicitly sets the field to a previous value, it will override the business rule's update. This is a common conflict between server-side business rules and client-side scripts.

Answer

The form is not refreshing after submission.

Answer

The business rule is set to run asynchronously.

Answer

A UI Policy is hiding the field.

Question 7

Which THREE statements are true about database views in ServiceNow?

Accepted Answer

Database views can have fields from multiple tables. Option A is correct because a ServiceNow database view is built by joining two or more tables (via a Database View definition with a where clause and left join), so its fields can be drawn from multiple tables. Option C is correct because database views appear as a table-like data source and can be selected as the source when creating reports in the Report Designer. Option D is correct because database views are read-only constructs; records returned by a view cannot be inserted, updated, or deleted directly through the view. Option B is incorrect because ServiceNow database views only join tables within the same instance, not tables from different instances or external databases. Option E is incorrect because, since views are read-only, business rules cannot be used to update records through the view.

Answer

Database views can reference tables from different instances or databases

Answer

Database views can be updated via business rules

Question 8

A UI Macro that displays a custom header is not appearing on the form. The macro is referenced in a UI16 theme. What is the first troubleshooting step?

Accepted Answer

Examine the UI Macro record for syntax errors in the HTML or Jelly script.. The first troubleshooting step is to examine the UI Macro record for syntax errors in the HTML or Jelly script, because a syntax error will prevent the macro from rendering entirely. This is the most direct way to identify why the macro is not appearing, as it checks the macro's definition before investigating integration points.

Answer

Check the browser's HTML source for the macro's placeholder.

Answer

Ensure the UI Macro is in the global scope.

Answer

Verify that all referenced UI Scripts are loaded.

Question 9

A company uses ServiceNow to manage IT assets. An integration sends asset data from an external CMDB to ServiceNow via REST API. The external system sends a payload that includes the asset's serial number, location, and status. The developer has created a Scripted REST API to receive this data. However, when testing, the external system receives an HTTP 500 error. The developer inspects the script log and sees the error: 'java.lang.NullPointerException' at line 10 of the script. The script uses the GlideRecord API to query for an existing asset by serial number. The relevant code is: var gr = new GlideRecord('alm_asset'); gr.get('serial_number', request.body.serial); What is the most likely cause of the NullPointerException?

Accepted Answer

The request body is not being parsed; 'request.body' is null because the content type is not set to JSON or the API is not expecting a body. The NullPointerException occurs when trying to access a property of a null object. In this case, `request.body` is null, meaning the request body was not parsed into a JavaScript object. This typically happens when the Content-Type header is not set to `application/json` or the Scripted REST API endpoint is not configured to expect a request body, so `request.body.serial` evaluates to `null.serial`, causing the exception.

Answer

The 'serial_number' field in the 'alm_asset' table does not exist or is misspelled

Answer

The GlideRecord.get() method is incorrectly used; it should be gr.get('serial_number') without the value

Answer

The external system is sending the serial number as part of the URL instead of the request body

Question 10

Drag and drop the steps to create a new Notification in ServiceNow into the correct order.

Accepted Answer

Navigate to Notifications, then click New, then set the table and name, then define the condition, then configure email details, then submit.. The sequence: navigate to Notifications, create new, set table and name, define conditions, configure email details, and submit.

Answer

Navigate to Notifications, then click New, then configure email details, then define the condition, then set the table and name, then submit.

Answer

Navigate to Notifications, then click New, then define the condition, then set the table and name, then configure email details, then submit.

Answer

Click New, then navigate to Notifications, then set the table and name, then define the condition, then configure email details, then submit.

Question 11

A UI Policy is used to make a field mandatory when another field has a specific value. The policy is not triggering. What is the first step to troubleshoot?

Accepted Answer

Review the UI Policy conditions and the order of policies on the form. When a UI Policy is not triggering, the first step is to review the UI Policy conditions and the order of policies on the form. This ensures the condition is correctly set and not overridden by other policies. Option A is incorrect because script includes are not typically used in UI Policy conditions; UI Policies use simple conditions or scripts that can access script includes, but verifying accessibility is not the first step. Option B is incorrect because the 'Mandatory' attribute on the dictionary is a different configuration; UI Policy can make a field mandatory irrespective of dictionary attributes. Option C is incorrect because ACLs control access, not mandatory behavior; they do not prevent UI Policy from making a field mandatory.

Answer

Verify that a script include used in the condition is accessible

Answer

Ensure the field has a 'Mandatory' attribute on the dictionary

Answer

Check if the 'Mandatory' ACL on the field prevents modification

Question 12

Which TWO data types are available in ServiceNow for storing date and time values?

Accepted Answer

Date/Time. ServiceNow provides two dedicated data types for storing date and time values: 'Date' for calendar dates without time, and 'Date/Time' for combined date and time values. These are the correct choices because they directly map to the platform's field types used in tables like Task and Incident for tracking creation and due dates.

Answer

Time

Answer

Duration

Answer

Timestamp

Question 13

A developer needs to add a custom button to the incident form that executes a script when clicked. Which mechanism should be used?

Accepted Answer

Create a UI Action.. The correct answer is C, Create a UI Action. A UI Action is the ServiceNow mechanism specifically designed to add buttons, links, or context menu items to a form, and it can be configured with a client-side script that runs when the button is clicked. This directly satisfies the requirement of a custom button on the incident form that executes a script. Option A is incorrect because client scripts cannot add buttons to a form; they only run on form events like onLoad, onChange, or onSubmit. Option B is incorrect because form layout controls field placement, not button widgets. Option D is incorrect because a UI Policy dynamically changes field behavior (mandatory, read-only, visible) and does not create buttons.

Answer

Write a client script that adds a button dynamically.

Answer

Modify the form layout to include a button widget.

Answer

Configure a UI Policy.

Question 14

A business rule on the Change Request table needs to update a field on the same record after the record is updated. Which 'When' option should be used?

Accepted Answer

After. 'After' runs after the database operation and is appropriate for updating the same record after the fact. Option A is incorrect because 'Display' runs when the form is displayed, not after the record is updated. Option C is incorrect because 'Async' runs asynchronously, but 'After' is the appropriate synchronous choice for updating after the record is saved. Option D is incorrect because 'Before' runs before the database operation, not after.

Answer

Display

Answer

Async

Answer

Before

Question 15

A developer is creating a REST API endpoint in ServiceNow that must accept JSON payloads and return a response. Which method should be used to parse the incoming request body?

Accepted Answer

JSON.parse(request.body). In ServiceNow scripted REST APIs, the incoming request body is available as a string via `request.body`. To parse JSON payloads, you must use `JSON.parse(request.body)` to convert the string into a JavaScript object. Option B (`request.body.data`) is not a standard property; the request body is a single string. Option C (`dataString`) is not a property of the request object. Option D (`bodyJSON`) is not a method or property; it does not exist in the ServiceNow REST API context.
