SNOW-CAD Practice Test 5 — 10 Questions

Question 1

A developer wants to add a new field to a table that is part of a scoped application. What is the correct method in Studio?

Accepted Answer

Create a new field in the application's schema.. In a scoped application, the proper method to add a new field is to create it in the application's schema within Studio. Option A is incorrect because right-clicking a table does not provide an 'Add Field' option. Option C is incorrect because Application Builder is used for building applications, not adding fields directly. Option D is incorrect because System Definition > Tables is for global tables, not scoped application tables.

Answer

In Studio, right-click the table and select 'Add Field'.

Answer

Use the Application Builder to add a table extension.

Answer

Navigate to System Definition > Tables and add the field.

Question 2

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

Accepted Answer

They can use AngularJS services like $http and $timeout.. 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 3

Which TWO application file types can be exported as XML from Studio?

Accepted Answer

Business Rules. Options A and D are correct because Business Rules and UI Policies are standard application files that can be exported as XML from Studio. Option B (Reports) is wrong because Reports are not application files; they are stored separately. Option C (System Properties) is wrong as they are configuration items, not exported via Studio. Option E (Homepages) is wrong because Homepages are not application files and cannot be exported as XML from Studio.

Answer

Reports

Answer

System Properties

Answer

Homepages

Question 4

Which TWO approaches are valid for importing data from an external database into ServiceNow on a recurring basis? (Choose two.)

Accepted Answer

Set up a MID Server to run a scheduled transform map from an external SQL query.. A MID Server can execute a scheduled SQL query against an external database and then run a transform map to map the retrieved data into ServiceNow tables. This approach is a standard pattern for recurring data imports using the MID Server's JDBC capabilities combined with scheduled import sets.

Answer

Use a REST API with a periodic flow that calls an external endpoint.

Answer

Write a business rule that triggers on an external event via web service.

Answer

Use an email inbound action to parse CSV attachments from the external system.

Question 5

A developer is troubleshooting a client script that hides a field on a form when a condition is met, but it is not working. The script is attached to the 'g_form' object in Studio. What is the most likely reason?

Accepted Answer

The client script is set to run on the 'Load' event instead of 'Change'.. The most likely reason because client scripts that need to react to a condition change must be set to run on 'Change' event rather than 'Load'. If the script runs only on 'Load', it executes once when the form loads and will not re-run when the condition changes, so the field remains visible. Option B is incorrect because the API for hiding fields (e.g., g_form.setVisible) is not deprecated. Option C is incorrect because client scripts do not have a 'Run As' role; that applies to server-side scripts. Option D is incorrect because client scripts can access any field present on the form regardless of the field's scope.

Answer

The script is using a deprecated API.

Answer

The script is not running due to a missing 'Run As' role.

Answer

The field is not part of the application scope.

Question 6

A company has a business rule on the Task table that runs on 'before' insert. The rule uses current.gotoField('short_description') and current.setValue('short_description', 'Default'). The rule is ordered to run at 500. However, a second business rule on the same table with order 100 also sets the short_description. What will be the final value of short_description?

Accepted Answer

'Default'. Business rules execute in ascending order based on their 'order' field. The rule at order 100 runs first and sets the short_description. Then the rule at order 500 runs and overrides that value with 'Default' using current.setValue(). Since both are 'before' insert rules, the final value written to the database is the one set by the last-executed rule, which is order 500.

Answer

Both values will be concatenated

Answer

The value set by the rule at order 100

Answer

The field will be empty because gotoField() clears it

Question 7

A large financial institution has a custom application for managing trade requests. The application uses a business rule on the 'Trade' table that calculates and sets the 'net_value' field based on 'quantity' and 'price'. Recently, traders have reported that when they update existing trades via a REST API integration, the 'net_value' field is not being recalculated. The business rule is set to run 'before' insert and 'before' update. The REST API uses GlideRecord to update the trade records. Upon investigation, the developer finds that the business rule script includes a check: 'if (current.changes('quantity') || current.changes('price')) { // recalculate }'. The script works correctly when updates are made from the UI. What is the most likely cause of the issue?

Accepted Answer

The GlideRecord used in the REST API does not load the record's previous values, so changes() returns false.. The GlideRecord API used in REST API integrations does not automatically load the previous values of fields into the `changes()` method. When a record is updated via GlideRecord in a scripted REST API, the `current` object in the business rule does not have the 'previous' values populated, so `current.changes('quantity')` and `current.changes('price')` both return `false`. This causes the recalculation logic to be skipped, even though the business rule is set to run 'before update'. In contrast, UI updates load previous values correctly, making `changes()` work as expected.

Answer

The business rule is set to run 'before' update, but the REST API triggers 'after' update.

Answer

The REST API sends the update request to a different instance, bypassing the business rule.

Answer

The condition 'current.changes('quantity') || current.changes('price')' is incorrectly formatted; it should use 'current.changes('quantity') || current.changes('price')'.

Question 8

A team is using a SOAP web service integration. The response contains namespaced XML, and the script that parses it is not extracting values correctly. What is the most likely issue?

Accepted Answer

Missing or incorrect namespace prefix handling in the script. Namespaced XML requires proper namespace prefix handling to extract values; if the script lacks or mismatches prefixes, parsing fails. Option A is incorrect because WSDL caching affects endpoint updates, not parsing. Option B is incorrect because SOAP version mismatch typically causes communication errors, not parsing issues. Option C is incorrect because HTTP timeout would result in no response, not incorrect value extraction.

Answer

WSDL caching prevents updated endpoint

Answer

SOAP version mismatch between request and response

Answer

HTTP timeout during response retrieval

Question 9

A company has a custom table 'u_employee' with fields: 'first_name', 'last_name', 'department'. They want to create a unique index on the combination of 'last_name' and 'department' to prevent duplicate entries. Where should this index be defined?

Accepted Answer

In the table's dictionary record via the Indexes related list. In ServiceNow, a unique index on a custom table is defined in the table's dictionary record via the Indexes related list. This is the correct location because ServiceNow uses the table's dictionary metadata to manage indexes, and the Indexes related list allows you to specify unique constraints directly on the table definition, ensuring the database enforces uniqueness on the combination of 'last_name' and 'department'.

Answer

In the table schema map

Answer

In the dictionary entry for each field

Answer

In the sys_dictionary table directly

Question 10

Which record type should be used to customize the look and feel of the UI16 interface?

Accepted Answer

UI Theme (sys_ui_theme). UI Theme (sys_ui_theme). In ServiceNow, the UI16 interface's look and feel is customized using UI Themes, which are stored in the 'sys_ui_theme' table. Option A (UI Script) is incorrect because UI Scripts are used for client-side JavaScript functions, not for theming. Option B (Portal Theme) is meant for Service Portal configurations, not the UI16 interface. Option D (Branding) handles logos, colors, and fonts but does not provide the full theme customization capabilities of UI Themes.

Answer

UI Script (sys_ui_script)

Answer

Portal Theme (sp_theme)

Answer

Branding (sys_brand)
