SNOW-CAD Practice Test 5 — 10 Questions

Question 1

A Service Portal widget is failing to update a reference field on a form after a user selects a value from a reference picker. The developer reviews the widget's client controller and sees the following code snippet: $scope.c.data.selectedItem = value; The server script expects 'selectedItem' to be a sys_id string, but it is receiving an object. What is the most likely cause?

Accepted Answer

The reference field returns an object with 'value' and 'display' properties; the code should extract the sys_id.. Option D is correct because when a reference picker returns a value in Service Portal, it typically provides an object containing both the display value and the sys_id (e.g., {value: 'sys_id', display: 'name'}). The client controller code assigns this entire object to $scope.c.data.selectedItem, but the server script expects a plain sys_id string. The developer must extract the sys_id property (e.g., value.sys_id or value.value) before assigning it to the scope variable.

Answer

The server script expects the parameter in a different scope variable, like $scope.c.data.item.

Answer

The $scope.c.data assignment is incorrect; it should be $scope.data.

Answer

The client controller is not allowed to set $scope.c variables.

Question 2

A developer is designing a custom form in the standard UI (UI16) and needs to add a message that displays only when the 'state' field is 'Closed'. Which feature should be used to achieve this without custom scripting?

Accepted Answer

Create a UI Policy that adds a message when the condition state=Closed is true.. UI Policies are the correct declarative feature in UI16 to show a message based on a field value without custom scripting. They run on the client side and can display informational, warning, or error messages when a specified condition (like state=Closed) is met, making option A the appropriate choice.

Answer

Create a form section and set its condition via the 'Conditional' property.

Answer

Write a Client Script that shows a message when state changes to Closed.

Answer

Use a UI Macro with a condition that checks the state field.

Question 3

This client script is attached to the 'category' field on the incident form. When the user changes the category to 'Network', what happens to the short_description field?

Accepted Answer

The short_description is set to 'Category changed to Network'.. Option B is correct because the client script checks if the newValue of the 'category' field is not empty and equals 'Network'. When the user changes the category to 'Network', newValue is 'Network', which passes the empty check (newValue !== ''), and then the condition newValue === 'Network' is true. The script then executes g_form.setValue('short_description', 'Category changed to Network'), which sets the short_description field to that string.

Answer

Nothing happens because newValue equals 'Network' which passes the empty check.

Answer

An error occurs because setValue cannot be called with a string.

Answer

The short_description is cleared.

Question 4

During development, a developer creates a new application module and adds a table 'x_abc_incident' with a reference field to the 'sys_user' table. The developer wants to ensure that when a user is deleted, all related incident records are also deleted. What database constraint should be configured on the reference field?

Accepted Answer

Cascade delete. Option A is correct because a cascade delete constraint ensures that when a record in the parent table (sys_user) is deleted, all child records in the referencing table (x_abc_incident) that have a foreign key pointing to that parent are automatically deleted. In ServiceNow, this is configured on the reference field's 'Delete constraint' property by selecting 'Cascade delete', which enforces referential integrity at the database level.

Answer

No action

Answer

Restrict delete

Answer

Set null on delete

Question 5

A developer needs to import data from a CSV file into a custom table. Which ServiceNow module should be used for this task?

Accepted Answer

Import Sets. Import Sets are the correct ServiceNow module for importing data from a CSV file into a custom table. They provide a structured pipeline that maps CSV columns to table fields, with staging tables for validation before final insertion. This is the standard approach for one-time or recurring data imports in ServiceNow.

Answer

Scheduled Jobs

Answer

Update Sets

Answer

Data Source

Question 6

A developer writes a business rule that queries the 'incident' table using GlideRecord. The script loops through all incidents and updates a field. After running, the developer notices that only a subset of records were updated. What is the most likely cause?

Accepted Answer

The GlideRecord query did not include a condition, so it used a default filter that limited results. Option B is correct because GlideRecord queries in ServiceNow automatically apply a default filter when no explicit condition is set, typically limiting results to records where the `active` field is `true`. This default behavior, known as the 'active filter,' causes the script to only process a subset of incidents (those that are active) rather than all records in the table, explaining why only some were updated.

Answer

The user running the script lacks write ACL on the table

Answer

The field name used in the update was misspelled

Answer

The script did not call getRowCount() before the loop

Question 7

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.. Option B is correct because 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 8

A ServiceNow instance is being integrated with an external HR system using a SOAP message. The SOAP call is failing intermittently. The developer notices that the XML payload contains special characters like '&' and '<'. What is the best practice to handle these characters in SOAP messages?

Accepted Answer

Escape the characters using XML entities (e.g., & for &).. SOAP messages are XML-based, and special characters like '&' and '<' must be escaped using XML entities (e.g., & for &, < for <) to maintain valid XML syntax. This ensures the XML parser correctly interprets the payload without breaking the message structure, which is the standard practice per the XML specification and SOAP protocol.

Answer

Wrap the payload in a CDATA section.

Answer

Encode the entire payload in Base64.

Answer

Use URL encoding for the payload.

Question 9

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 10

A company wants to allow their customers to submit requests via email. The email should create a new record in the 'Request' table. Which component should be used to define the mapping of email fields to the ServiceNow table fields?

Accepted Answer

Inbound Email Action. An Inbound Email Action is the correct component because it defines the mapping of email fields (e.g., subject, body, sender) to ServiceNow table fields (e.g., 'Short description', 'Description', 'Caller'). It uses a script or condition to parse the incoming email and create or update records in a specified table, such as the 'Request' table. This is the standard mechanism for turning an email into a ServiceNow record.

Answer

Email Account

Answer

Inbound Email Script

Answer

Email Notification
