SNOW-CAD Practice Test 16 — 15 Questions

Question 1

A developer builds an application in Studio and wants to ensure all changes are captured in an update set. What is true?

Accepted Answer

Studio automatically creates an update set for the application scope when the application is created.. Studio automatically creates an update set for the application scope when the application is created. Option A is incorrect because the developer does not need to manually set the 'Update Set' field on each record; Studio automatically associates changes with the scope's update set. Option C is incorrect because update sets are used for scoped applications; each application scope has its own update set. Option D is incorrect because Studio automatically creates and assigns the update set; manual creation is not required.

Answer

The developer needs to set the 'Update Set' field on each record to 'Default Update Set'.

Answer

Update sets are not used for scoped applications; only for global scope.

Answer

The developer must manually create a new update set and assign it to the application scope.

Question 2

Which TWO of the following are valid methods to create a new application scope in ServiceNow Studio?

Accepted Answer

Click 'Create Application' in the Studio dashboard.. The valid methods to create a new application scope in ServiceNow Studio are clicking 'Create Application' in the Studio dashboard (D) and cloning an existing application (E). Options A, B, and C are not valid: converting a global table to scoped does not create an application scope; importing from an update set is for updating existing applications, not creating new ones; the Application Creation Wizard is not a method within Studio.

Answer

Convert a global table to scoped.

Answer

Import an application from an update set.

Answer

Use the Application Creation Wizard.

Question 3

A developer has created a custom application and wants to ensure that all changes are captured in an update set for migration. Which practice should be followed?

Accepted Answer

Use the 'Export to Update Set' feature in Studio.. In ServiceNow Studio, the 'Export to Update Set' feature allows developers to capture all changes made to an application and package them into an update set XML for migration. Option A is incorrect because setting an application to 'Published' does not automatically create update sets. Option B is incorrect because the 'Update Sets' module manages existing update sets, not capturing application changes. Option D is incorrect because manually copying changes is error-prone and not a practice for migration.

Answer

Set the application to 'Published' to automatically create update sets.

Answer

Use the 'Update Sets' module to capture all changes from the application.

Answer

Manually copy changes to another instance.

Question 4

A developer is creating a Scheduled Job in Studio that needs to run every hour. Which type of trigger should be selected?

Accepted Answer

Interval. (Interval) is correct because an Interval trigger allows you to specify a repeat interval, such as every 60 minutes, which meets the requirement to run every hour. Option A (Date) runs once at a specific date/time. Option B (Run once) runs a single time. Option D (Daily) runs once per day.

Answer

Date

Answer

Run once

Answer

Daily

Question 5

A developer is designing a UI Policy that should run client-side but references a complex server-side calculation. Which approach is best?

Accepted Answer

Use a client script with GlideAjax.. The correct approach is to use a client script with GlideAjax (Option B) because UI Policies run client-side and cannot directly perform complex server-side calculations. GlideAjax allows asynchronous calls to a server-side script include, enabling the client script to retrieve the result of a complex server-side calculation without a page refresh. Option A is incorrect because Business Rules run server-side and cannot be called directly from a UI Policy; they are triggered by database operations. Option C is incorrect because UI Macros are used for reusable UI components, not for server-side logic. Option D is incorrect because UI Policy condition strings are limited to simple client-side expressions and cannot execute complex server-side calculations.

Answer

Create a Business Rule and call it from UI Policy.

Answer

Use a UI Macro.

Answer

Use a UI Policy condition string.

Question 6

Which THREE considerations are important when designing a scoped application for a customer?

Accepted Answer

Avoid modifying global tables directly.. When designing a scoped application in ServiceNow, it is crucial to avoid modifying global tables directly (B) to prevent unintended side effects and maintain upgradeability. The application name must be uniquely scoped (C) to prevent conflicts with other applications. Including only necessary features (E) reduces complexity and improves performance. Option A is incorrect because minimizing update sets is not a design consideration; update sets are for deployment management. Option D is incorrect because using global Business Rules contradicts the purpose of scoping and can cause cross-scope issues.

Answer

Minimize number of update sets.

Answer

Use global Business Rules for performance.

Question 7

A company needs to store data about employee certifications. Each employee may have multiple certifications. Which approach is best practice?

Accepted Answer

Create a new custom table with a reference field to the User table. Creating a new table with a reference field to the User table allows storing multiple certification records per employee without adding unnecessary fields. Option A is wrong because a multi-select field on the User table cannot effectively store multiple certification records and lacks relational integrity. Option C is wrong because extending the User table would add many unwanted fields from the User table and complicate data management. Option D is wrong because database views are read-only and cannot be used for storing data.

Answer

Add a multi-select field to the User table to store certification IDs

Answer

Extend the User table to store certification fields directly

Answer

Create a database view that joins User and certification data

Question 8

An organization wants to store customer feedback data in a custom table. The feedback will have a large text field for comments, a reference to the customer, and a date field. Which data type should be used for the comments field to support rich text including HTML?

Accepted Answer

HTML. The 'HTML' data type stores rich text with HTML formatting. Option A is wrong because 'String' does not support HTML rendering. Option B is wrong because 'Journal Entry' is for audit trail. Option D is wrong because 'Report Text' is not a valid data type.

Answer

Report Text

Answer

String

Answer

Journal Entry

Question 9

A custom table 'u_asset' extends the 'cmdb_ci' table. Users report that the 'manufacturer' field is not visible on the 'u_asset' form. What is the most likely cause?

Accepted Answer

The u_asset form layout does not include the manufacturer field. The form layout for the custom table 'u_asset' is separate from the parent 'cmdb_ci' form layout. Even though 'manufacturer' is inherited from 'cmdb_ci', it must be explicitly added to the u_asset form layout. Option A is wrong because the manufacturer field is indeed part of the cmdb_ci table. Option C is incorrect because ACLs control access but do not hide fields from the form layout unless configured; ACLs are not the likely cause. Option D is irrelevant because mandatory setting does not affect visibility.

Answer

The manufacturer field is not part of the cmdb_ci table

Answer

An ACL on the u_asset table hides the manufacturer field

Answer

The dictionary entry for manufacturer has mandatory set to false

Question 10

Refer to the exhibit. A developer wrote this script in a Business Rule on the 'incident' table. The script runs but the 'u_field' value is not saved. What is the most likely cause?

Accepted Answer

The u_field is defined as read-only. If the 'u_field' is defined as read-only (e.g., via dictionary attribute or ACL), the setValue method fails silently, meaning the value is not saved but no error is thrown. Option A is incorrect because the script appears syntactically correct. Option B is incorrect because setValue does exist on GlideElement. Option D is incorrect because setValue is the appropriate method for setting field values; setDisplayValue is used for setting display values, not database values.

Answer

The script has a syntax error

Answer

The setValue method does not exist on GlideElement

Answer

The method should be setDisplayValue, not setValue

Question 11

Which TWO of the following are valid table types in ServiceNow?

Accepted Answer

Extendible. Options D and E are correct. 'Extendible' (tables that can be extended) and 'Database view' (virtual tables based on SQL views) are valid table types in ServiceNow. Option A is incorrect because 'Dictionary' is a table that stores system metadata, not a table type. Option B is incorrect because 'Application' is not a table type; applications contain tables. Option C is incorrect because 'UI page' is a UI component, not a table type.

Answer

Dictionary

Answer

Application

Answer

UI page

Question 12

A company needs to create a lookup table to store status codes for incident classification. Which approach is best practice?

Accepted Answer

Use a Choice field with the status codes and labels. Using a Choice field is standard for static lists. Option A is wrong because creating a table is overkill for simple lists. Option C is wrong because it loses referential integrity. Option D is wrong because creating a custom table with a reference field on the Incident table adds unnecessary complexity when a simple Choice field suffices.

Answer

Create a new table using the Label field type

Answer

Store the status codes as a single line of text field

Answer

Create a custom table with a reference field on the Incident table

Question 13

An administrator notices that a custom table called 'u_equipment' does not appear in the 'New Record' context menu of the application navigator. What is the most likely cause?

Accepted Answer

The table was not added to an application menu in the navigation module. Custom tables must be added to an application menu in the navigation module to appear in the 'New Record' context menu. Option B is incorrect because tables extended from a parent table can appear independently if configured. Option C is incorrect because business rules do not affect navigator menu visibility; they only influence record creation actions. Option D is incorrect because the 'Create new' option is not inherited from the parent table; it requires explicit configuration.

Answer

The table is extended from a table that is not in the navigator

Answer

The table has a business rule that prevents new record creation

Answer

The 'Create new' option is inherited from the parent table

Question 14

A company wants to display a list of open incidents on a Service Portal page. Which component should be used?

Accepted Answer

Data Table Widget. The Data Table Widget is the standard component for displaying lists of records in Service Portal, making option B correct. Option A (Map Widget) is used for geospatial data. Option C (Performance Analytics widget) is for analytics dashboards. Option D (List View Widget) is designed for the backend UI, not for portals.

Answer

Map widget

Answer

Performance Analytics widget

Answer

List View Widget

Question 15

A large enterprise runs ServiceNow on a single instance. They have a custom table 'u_project_task' that stores task details for projects. Each project task has a reference field to the 'u_project' table. The 'u_project' table has approximately 50,000 records, and the 'u_project_task' table has about 2 million records. Users report that opening a project record and viewing its related tasks takes over 30 seconds. The system uses an out-of-box related list to display tasks. The instance has standard hardware resources. The administrator has already confirmed that there are no performance issues with the database server or network. Which course of action should the administrator take to improve the performance of the related list?

Accepted Answer

Create a database index on the 'u_project' field in the 'u_project_task' table to speed up the join.. The performance bottleneck is the database query that joins the large 'u_project_task' table (2M records) with the 'u_project' table on the reference field. Without an index on the 'u_project' field in 'u_project_task', the database must perform a full table scan for each related list query. Creating a database index on that foreign key column allows the database to use an index seek, dramatically reducing query time.

Answer

Archive project tasks older than 1 year to a separate table to reduce the data volume.

Answer

Increase the glide.ui.related_list.max_timeout property to allow the query more time.

Answer

Add additional application nodes to the instance to distribute the load.
