SNOW-CAD Application development using ServiceNow Studio Practice Test 3 — 15 Questions

Question 1

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.. Option B is correct because Studio's 'Export to Update Set' feature packages all application changes into an update set XML. Option A is manual and error-prone, C is not a built-in feature, and D may miss scope-specific changes.

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 2

In ServiceNow Studio, when developing a flow that requires a decision based on a record's category, which component should be used?

Accepted Answer

Condition. Option A is correct because a Condition component is used to evaluate criteria and branch the flow. Action performs operations, Trigger initiates the flow, and Flow Logic is not a component.

Answer

Action

Answer

Flow Logic

Answer

Trigger

Question 3

A developer wants to create a new UI action that appears on the form only when the record is in a specific state. Which property should be configured?

Accepted Answer

Script condition. Option B is correct because the 'Script condition' property allows writing a script to dynamically determine visibility based on state. Option A is for simple conditions but not always sufficient, and C and D are unrelated.

Answer

Condition field

Answer

Form context menu

Answer

Insert field

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. Option A is correct because an Interval trigger allows specifying a repeat interval, e.g., every 60 minutes. Daily runs once per day, Date runs at a specific date/time, and Run once runs one time.

Answer

Date

Answer

Run once

Answer

Daily

Question 5

When building a custom application using ServiceNow Studio, which of the following is NOT a recommended practice for version control?

Accepted Answer

Directly edit system tables outside of the application scope.. Option C is correct because directly editing system tables outside the application scope can cause conflicts and is not version-controlled within the application. Options A, B, and D are recommended practices.

Answer

Create a new application version for each major release.

Answer

Track changes using update sets.

Answer

Use application scope to isolate changes.

Question 6

A developer needs to implement a server-side validation that prevents update to a record if a related record's status is 'Closed'. Where should this logic be placed?

Accepted Answer

Business rule. Option A is correct because a business rule runs server-side when a record is updated and can enforce the validation before the update occurs. Client scripts and UI policies are client-side and can be bypassed. ACLs are for access control, not validation.

Answer

ACL

Answer

Client script

Answer

UI policy

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 C are correct. The business rule must be active and must have a condition that evaluates to true. Option A (order) matters only if multiple rules conflict, but is not the first check. Option D is not possible; business rules cannot be run manually. Option E is not relevant.

Answer

Check the business rule order.

Answer

Run the business rule from the context menu.

Answer

Check if the table is locked.

Question 8

In ServiceNow Studio, which TWO elements can be created directly from the 'Create Application File' wizard? (Choose two.)

Accepted Answer

Table. Options A and D are correct. Tables and Business Rules are standard application files that can be created via the wizard. Update Sets (B) are not created as application files; they are containers for changes. System Properties (C) and Flows (E) are created through other modules (e.g., sys_properties, Flow Designer).

Answer

Flow

Answer

System Property

Answer

Update Set

Question 9

A developer is creating an application in ServiceNow Studio and needs to ensure that all new records created in a custom table are automatically assigned a number. Which THREE methods can be used to achieve this? (Choose three.)

Accepted Answer

Use a default value on the number field.. Options A, B, and C are correct. A business rule can set the number via script, a flow can assign a number using a 'Create Record' step, and a default value on the number field will apply automatically. Option D (client script) is unreliable because it runs client-side and can be bypassed. Option E (database view) does not generate numbers.

Answer

Use a database view to generate numbers.

Answer

Use a client script to set the number on load.

Question 10

Refer to the exhibit. What is the primary issue with this script if it is intended to update all incidents in state 'New' (state=1) to priority 2?

Accepted Answer

The script will cause an infinite loop.. Option A is correct. Using gr.update() inside the while loop on the same GlideRecord object can cause an infinite loop if any business rule or trigger re-queries the same record set. This is a known anti-pattern. Option B is incorrect because setValue syntax is fine. Option C is partially true but not the primary issue. Option D is incorrect because next() iterates correctly.

Answer

The script will not update any records because of a syntax error in setValue.

Answer

The script will update only the first record because next() is used incorrectly.

Answer

The script will update records but may cause performance issues.

Question 11

Refer to the exhibit. The above JSON represents an application manifest generated by Studio. What does the dependency on 'global' with version '>=3.0.0' indicate?

Accepted Answer

The application must be installed on an instance with ServiceNow version 3.0.0 or later.. Option B is correct. In ServiceNow application manifests, a dependency on 'global' refers to the platform version (ServiceNow release). It means the application requires the instance to be at least version 3.0.0. Option A confuses update sets, C misinterprets scope, and D is incorrect.

Answer

The application requires an update set from global scope.

Answer

The application depends on another application with scope 'global' that must be at least version 3.0.0.

Answer

The application's global update set must be at version 3.0.0.

Question 12

Refer to the exhibit. What does this script do?

Accepted Answer

Updates the state of incident INC001234 to 2.. Option A is correct. The script retrieves the incident with number 'INC001234', sets its state to 2, and updates the record. Option B would require deleteRecord(), C would require insert(), and D is false because get returns true if found.

Answer

Does nothing because get returns false.

Answer

Creates a new incident.

Answer

Deletes the incident.

Question 13

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.. Option A is correct because Scripted REST API allows creating custom endpoints in Studio. Option B is wrong as the table API requires ACLs and is not directly available. Option C is wrong because configuring from the system Web Services menu is not part of Studio. Option D is wrong because generating an API from the Application Menu is not a standard Studio feature.

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 14

After importing an update set from another instance, a scoped application shows multiple conflicts in Studio. What is the best first step to resolve?

Accepted Answer

Review each conflict and choose the correct version.. Option C is correct because reviewing each conflict and choosing the correct version ensures no unintended changes. Option A is wrong because blindly accepting remote changes may overwrite necessary local modifications. Option B is wrong because discarding local changes could lose important work. Option D is wrong as it is drastic and unnecessary.

Answer

Delete the application and re-import.

Answer

Discard all local changes.

Answer

Accept all remote changes.

Question 15

A developer is building a scoped application in Studio that needs to access global records. Which application property should be enabled?

Accepted Answer

Allow read/write access to tables in global scope.. Option B is correct because 'Allow read/write access to tables in global scope' permits the application to interact with global tables. Option A is wrong as it is not a valid property. Option C is wrong because 'Export table data' is for data export. Option D is wrong as it controls access from other scopes.

Answer

Allow access to this application from all scopes.

Answer

Allow access to all scoped applications.

Answer

Export table data.
