SNOW-CAD Practice Test 16 — 15 Questions

Question 1

Refer to the exhibit. An inbound REST call (GET) to the 'incident' table is returning a 403 error. The ACL shown in the exhibit is the only ACL on the table. The calling user has the 'incident_manager' role. What is the likely cause of the 403 error?

Accepted Answer

The ACL requires the 'admin' role, but the user has 'incident_manager'.. The ACL script explicitly requires the 'admin' role. Since the user has 'incident_manager' but not 'admin', the ACL denies access, resulting in a 403 Forbidden error.

Answer

The ACL script is malformed.

Answer

The ACL operation is 'read' but the REST call is a POST.

Answer

The user does not have the 'rest_api' role.

Question 2

The script above fails with HTTP 400 Bad Request. What is the most likely missing configuration?

Accepted Answer

The Content-Type header is not set to application/json. Option A is correct: missing Content-Type header set to application/json causes 400. Option B is wrong because method is POST, which is correct. Option C is wrong because Accept header is set. Option D is wrong because authentication would cause 401, not 400.

Answer

The HTTP method should be PUT instead of POST

Answer

Missing authentication credentials

Answer

The Accept header should be text/plain

Question 3

In a multi-instance environment, an organization wants to integrate ServiceNow with an on-premise database using JDBC. Which feature is used to establish this connection?

Accepted Answer

External Data Sources. External Data Sources are specifically designed to connect ServiceNow to external databases via JDBC, enabling data synchronization.

Answer

REST API

Answer

Import Set

Answer

SOAP Web Service

Question 4

The transform map fails when the source field 'u_summary' is null. What is the best way to prevent this error?

Accepted Answer

Add a null check before setting: if(source.u_summary) target.setValue('short_description', source.u_summary);. Option D is correct: check for null before setting. Option A is wrong because the script does not need a return. Option B is wrong because setValue is correct method. Option C is wrong because system fields are not the issue.

Answer

Use target.short_description = source.u_summary instead

Answer

Add a 'return true;' statement at the end

Answer

Map to a system field like 'sys_created_by'

Question 5

A developer is investigating why an outbound REST message is not sending data correctly. Which TWO actions should the developer check first? (Choose two.)

Accepted Answer

Check the authentication profile.. The most immediate checks are the endpoint URL to ensure it is correct, and the authentication profile to ensure credentials are valid. These are common causes of failures.

Answer

Restart the web server.

Answer

Reinstall the ServiceNow instance.

Answer

Review the script include for errors.

Question 6

A developer is configuring a REST message to retrieve data from an external system. The external system returns XML responses. Which data format should the developer set the REST message to expect?

Accepted Answer

XML. The REST message must be configured to expect the same data format that the external system returns. Since the external system returns XML, the developer should set the expected format to XML.

Answer

JSON

Answer

Text

Answer

CSV

Question 7

An organization is planning to import a large dataset into ServiceNow using import sets. According to best practices, which TWO actions should the developer take to optimize performance? (Choose two.)

Accepted Answer

Disable business rules and ACLs during import.. Scheduling imports during off-peak hours reduces load on the system. Disabling business rules and ACLs during import speeds up processing by avoiding unnecessary checks.

Answer

Increase the import set table row limit.

Answer

Enable 'Create multiple' for transform maps.

Answer

Use a single transform map for all records.

Question 8

A developer is writing a script to update a large number of records. To avoid hitting the execution time limit, what is the recommended approach?

Accepted Answer

Use GlideRecord with setLimit and a loop to process in batches.. Processing records in batches using setLimit and a loop prevents long-running scripts and allows the system to handle the load efficiently.

Answer

Use a single GlideRecord update with setWorkflow(false).

Answer

Use a scheduled job to run the script asynchronously.

Answer

Use a business rule to trigger the update on save.

Question 9

Which TWO are best practices for integrating with external systems via REST API in ServiceNow?

Accepted Answer

Store credentials in a credential store or use OAuth for authentication.. Options B and C are best practices. Using HTTPS secures data in transit, and using OAuth or a credential store enhances security over basic authentication.

Answer

Avoid using the GlideRecordSecure API for REST endpoints.

Answer

Use basic authentication with username and password for all REST API requests.

Answer

Use the sysparm_query parameter to limit the number of records returned.

Question 10

A company needs to create a new application in ServiceNow Studio. What is the correct first step?

Accepted Answer

Open Studio from the left navigation menu, then click 'Create Application'.. Option A is correct because opening Studio and clicking 'Create Application' is the standard method. Option B is incorrect because the System Applications module is deprecated for creating applications. Option C is incorrect because it creates individual files, not an application. Option D is incorrect because the Application Navigator does not have a 'create application' option.

Answer

Navigate to System Applications > Studio and click 'Create Application'.

Answer

Use the Application Navigator to create a new application.

Answer

Go to Application Files > New and select 'Application'.

Question 11

A developer is experiencing an issue where a client script is not executing in a scoped application. Which TWO of the following could be causing the issue?

Accepted Answer

The script has a syntax error.. Options A and D are correct: script in global scope (not accessible) and syntax error are common causes. Option B is a valid condition. Option C using global variable is fine. Option E is not a role requirement.

Answer

The user does not have the 'client_script_admin' role.

Answer

The script's 'Condition' is set to 'true'.

Answer

The script is using a global variable.

Question 12

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 13

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 14

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.

Question 15

Which of the following is a benefit of using ServiceNow Studio for application development?

Accepted Answer

It provides a guided interface to create application components.. Option D is correct because Studio provides a guided interface for creating application components. Option A is incorrect because developing in production is not recommended. Option B is incorrect as development does not automatically deploy to all instances. Option C is incorrect because Studio supports version control.

Answer

It allows development directly in the production instance.

Answer

It requires no version control.

Answer

It automatically deploys applications to all instances.
