SNOW-CAD Practice Test 18 — 15 Questions

Question 1

When creating a new table using the 'Create Table' module, which setting determines whether the table will inherit fields from an existing table?

Accepted Answer

Extends. 'Extends,' is correct because it allows the new table to inherit fields from an existing parent table. Option A, 'Application,' defines the application scope, not inheritance. Option C, 'Table name,' is the system name. Option D, 'Table label,' is the display name.

Answer

Application

Answer

Table name

Answer

Table label

Question 2

Refer to the exhibit. The Business Rule is set to run on before update. When a record's category is changed to 'hardware', the assignment group is updated correctly. However, when a record is inserted with category 'hardware', the assignment group is not set. Why?

Accepted Answer

The condition 'current.category.changes()' returns false on insert.. The condition 'current.category.changes()' checks if the category field has changed from its previous value. On insert, there is no previous value, so this condition returns false, causing the business rule to not execute the assignment group update. Option B is incorrect because the business rule does run on insert (it is configured to run on insert as well, despite the stem mentioning only 'before update'), but the condition fails. Option C is incorrect because the rule runs before the database operation. Option D is incorrect because setValue works on insert.

Answer

The Business Rule does not run on insert.

Answer

The Business Rule runs after the database operation.

Answer

The setValue method does not work on insert.

Question 3

A developer wants to customize the appearance of a Service Portal theme. Which approach is recommended to ensure maintainability and scalability?

Accepted Answer

Define CSS custom properties in the theme's stylesheet and use them throughout widgets. The recommended approach because CSS custom properties (CSS variables) allow centralized theme management in the theme's stylesheet, making them reusable across all widgets without duplication. This ensures maintainability and scalability. Option A is incorrect because LESS variables defined in widget styles are scoped to that widget and not shared globally, leading to duplication. Option B is incorrect because editing the default theme record directly can be overwritten during upgrades, causing maintenance issues. Option D is incorrect because inline styles are not scalable, hard to maintain, and cannot be overridden systematically.

Answer

Use LESS variables inside each widget's widget styles

Answer

Edit the default theme record to change primary colors

Answer

Apply inline styles directly in widget templates for fine-grained control

Question 4

An organization has a ServiceNow instance that integrates with an external HR system using a scheduled job that runs every hour. The job uses a REST message to fetch new hire records and creates user accounts in ServiceNow via a transform map. Recently, the number of new hires has increased significantly, and the job now takes over an hour to complete, causing the next job to start before the previous one finishes. The administrator notices that the transform map is using 'Coalesce' set to 'false' because the external system does not provide a unique identifier. The job also creates a large number of intermediate records that are later updated. The administrator wants to optimize the process to prevent overlapping job runs. Which course of action should the administrator take?

Accepted Answer

Set the 'Maximum rows to load' property on the transform map to a value that ensures the job finishes within 60 minutes. Setting the 'Maximum rows to load' property on the transform map limits the number of rows processed per run, ensuring the job completes within the 60-minute window. This prevents overlapping runs by capping the workload, allowing the scheduled job to finish before the next trigger, without requiring changes to the integration logic or external system.

Answer

Increase the scheduled job's interval to run every 2 hours to avoid overlap

Answer

Change the transform map to run asynchronously using a flow triggered by the import set row

Answer

Configure the import set table loader to run in multiple parallel threads to process records faster

Question 5

A data source is configured to import XML files from a REST endpoint. The XML contains nested elements. To properly map the data, which transform map feature is most useful?

Accepted Answer

Scripted transform with GlideRecord queries.. Scripted transforms allow custom JavaScript to parse and map nested XML elements using GlideRecord or other APIs, providing full flexibility when dot-walk notation is insufficient or not supported. Option A is incorrect because field mapping with dot-walk notation may not handle complex nested structures or special cases, and the reference to 'setEngine(false)' is invalid. Option B is incorrect because adjusting XML parsing settings affects parsing but not mapping. Option C is incorrect because choice mapping is for choice fields, not for nested data.

Answer

Field mapping using dot-walk notation in 'Field name to map to' column.

Answer

Adjust the data source's 'XML parsing' settings.

Answer

Use 'Choice mapping' to map nested values.

Question 6

A developer needs to expose a custom table's data via REST API in ServiceNow Studio. Which approach should they use?

Accepted Answer

Create a Scripted REST API in Studio.. The correct approach is to create a Scripted REST API in Studio (Option B). Studio provides a dedicated module for building custom REST APIs that can expose table data. Option A is incorrect because the system Web Services menu is not part of Studio and is used for configuring base REST APIs, not custom ones. Option C is wrong because generating an API from the Application Menu is not a standard Studio feature. Option D is incorrect because the table API requires additional configuration (ACLs) and is not directly accessible without setting up an endpoint.

Answer

Configure a REST API from the system Web Services menu.

Answer

Generate an API from the Application Menu.

Answer

Use the table API directly without any configuration.

Question 7

A developer is troubleshooting an issue where a business rule is not firing. Which TWO steps should the developer take to diagnose the problem? (Choose two.)

Accepted Answer

Ensure the business rule has a condition.. Options B and D are correct. To diagnose why a business rule is not firing, the developer should first verify that the business rule is active (D) and ensure it has a condition that evaluates to true (B). Checking the order (A) is only relevant when multiple business rules conflict, not a primary diagnostic step. Business rules cannot be run manually (C is incorrect), and table locking (E) is not related to business rule execution.

Answer

Check the business rule order.

Answer

Run the business rule from the context menu.

Answer

Check if the table is locked.

Question 8

A custom table 'u_incident' has a 'priority' field that should be set to 1 when the 'category' is 'Critical', otherwise 3. Which is the most efficient way to implement this default?

Accepted Answer

Define a default value script in the dictionary for the priority field. The most efficient way is to define a default value script in the dictionary for the 'priority' field. This script runs server-side during record insertion and sets the priority based on the category without additional database operations. Option A (Business Rule) works but adds overhead compared to a dictionary default. Option B (Client Script) is client-side and can be bypassed or not execute. Option C (UI Policy) only affects client-side behavior and does not set field values on the server.

Answer

Create a Business Rule on 'Before Insert' that sets the priority

Answer

Create a Client Script that runs onLoad and sets priority

Answer

Use a UI Policy to set priority based on category

Question 9

A company uses a business rule to set a field on the Incident table based on the caller's department. However, the rule runs correctly on insert but not on update. The developer suspects the condition is incorrect. The current script uses: if (current.operation() == 'insert' && gs.getUser().getDepartment() == 'IT'). What might be the issue?

Accepted Answer

The condition should check current.caller_id.department instead. The business rule should check the department of the caller associated with the incident record, not the logged-in user. The condition `current.caller_id.department` retrieves the department value from the caller's user record via a dot-walk to the sys_user table, ensuring the rule triggers based on the incident's caller, not the session user. The current script incorrectly uses `gs.getUser().getDepartment()`, which returns the department of the user running the update, which may differ from the caller's department, causing the rule to fail on update.

Answer

The rule is set to run only on insert

Answer

The script uses synchronous business rule instead of asynchronous

Answer

The condition should use current.operation() == 'update' as well

Question 10

Which TWO of the following are valid methods to create a custom table in ServiceNow?

Accepted Answer

Importing a CSV file via Import Set and selecting 'Create table automatically'.. Correct: B and D. Option B is valid because importing a CSV via an Import Set with the 'Create table automatically' option generates a new table based on the data structure. Option D is valid because the 'Create Table' module in System Definition provides a standard UI to create custom tables. Incorrect options: A is wrong because client scripts run in the browser and cannot create database tables. C is wrong because directly inserting into 'sys_db_object' bypasses required table creation processes and is not supported. E is wrong because a database view is a virtual representation of data from existing tables, not a physical table.

Answer

Using a client script to create a table on the fly.

Answer

By updating the 'sys_db_object' table directly with a new entry.

Answer

Using a database view to combine existing tables and then creating a table from the view.

Question 11

Which TWO are required for a reference field to automatically filter its choices based on the value of another field on the form (cascading)?

Accepted Answer

The reference qualifier must be a script that uses the parent field's value. Options B and E are correct. For a reference field to filter its choices based on the value of another field (cascading), the reference qualifier must be a script that uses the parent field's value (B). Additionally, the parent field must be present on the form containing the reference field (E). Option A is incorrect because the parent field does not need to be a reference field; it can be any field type. Option C is incorrect because, although the fields are on the same form, this condition is already covered by E. Option D is incorrect because there is no requirement for matching field names on the reference table.

Answer

The dependent field (parent) must be a reference field

Answer

Both fields must be on the same form

Answer

The reference table must have a field with the same name as the parent field

Question 12

A senior developer advises an associate to create a new table for storing incident-related attachments metadata. The table should not have its own workflow or assignments but should be related to incidents. Which table creation approach is best?

Accepted Answer

Create a table with a reference field to the Incident table.. The best approach is to create a custom table with a reference field to the Incident table (Option D). This allows storing metadata related to incidents without inheriting Incident's workflow, assignments, or other behaviors. Option A is incorrect because a database view is read-only and cannot store new data. Option B is incorrect because extending the Attachment table would inherit attachment-specific behaviors and is not appropriate for custom metadata. Option C is incorrect because extending the Incident table would inherit all Incident's features, including workflow and assignments, which the requirement specifically avoids.

Answer

Create a database view that joins Incident and Attachment tables.

Answer

Create a table that extends the Attachment table class.

Answer

Create a table that extends the Incident table.

Question 13

Which THREE of the following attributes can be set on a dictionary entry to affect how a field behaves?

Accepted Answer

Mandatory. Options B, C, and D are correct dictionary attributes that affect field behavior. 'Mandatory' (B) forces the field to be required. 'Default value' (C) sets an initial value for the field. 'Calculated' (D) enables a scripted calculated value, directly affecting how the field's value is determined. Option A ('Display') is a dictionary attribute that primarily controls which field to display in a reference field, not directly affecting field behavior. Option E ('Reference qualifier') is also a dictionary attribute, but it filters the records shown in a reference field, affecting record selection rather than the field's own behavior.

Answer

Display

Answer

Reference qualifier

Question 14

Which table property can be set to limit the creation of new records to certain roles?

Accepted Answer

Create access. The 'Create access' property on a table specifies which roles are allowed to create new records. Option A is incorrect: 'Allow attachment' controls whether users can add attachments to records, not creation. Option B is incorrect: 'Abbreviated table' sets a short name or prefix for the table, not access control. Option D is incorrect: 'Effective access' is a read-only property showing the user's current access rights, not a setting to restrict creation.

Answer

Allow attachment

Answer

Abbreviated table

Answer

Effective access

Question 15

A table 'u_inventory' has a reference field to the 'Location' table. The developer wants the reference field to display the location name instead of the sys_id in the form. Which attribute should be configured?

Accepted Answer

Reference display field. 'Reference display field'. This attribute on the dictionary entry of the reference field specifies which field from the referenced table (Location) to display in the form. Option A is wrong because 'Default value' sets a default value for the field, not the display. Option B is wrong because 'Reference qualifier' filters which records are available in the reference field. Option D is wrong because the 'Display' field on the Location table controls the default display of that table's records globally, but for a specific reference field, the 'Reference display field' overrides it.

Answer

Default value

Answer

Reference qualifier

Answer

Display field in the Location table
