SNOW-CAD Practice Test 5 — 25 Questions

Question 1

Refer to the exhibit. A UI Policy is defined on the Incident table. When will the 'assigned_to' field be hidden?

Accepted Answer

When the incident state is 1.. Option A is correct because the UI Policy in the exhibit is configured with a condition that hides the 'assigned_to' field when the 'state' field equals 1 (typically 'New'). UI Policies run client-side and evaluate the condition in real time; when the condition is true, the field is hidden. The exhibit shows the condition 'state = 1' with the 'Hidden' attribute checked, so the field is hidden only when the incident state is 1.

Answer

Never.

Answer

Always.

Answer

When the incident state is not 1.

Question 2

A developer is writing a business rule that should trigger on update of the 'short_description' field of an incident. The rule needs to check if the new value contains 'urgent' and, if so, set the priority to 1. Which TWO statements are true about implementing this rule?

Accepted Answer

The condition 'current.short_description.changes()' can be used to ensure the rule runs only when short_description changes.. Option A is correct because the changes() method on a GlideElement returns true only when the field's value has been modified during the current transaction. Placing `current.short_description.changes()` in the business rule's condition ensures the rule triggers only when the short_description field is updated, not on other field changes. Option B is correct because `current` always holds the updated record after the database write; thus `current.short_description` contains the new value. Options C and D are incorrect: `previous.short_description` holds the old value before the update, and `setValue()` is not a method on GlideRecord fields—priority should be set by direct assignment (e.g., `current.priority = 1`). Option E is incorrect because `current.short_description` is a GlideElement object, not a plain string; the indexOf() method does not exist on GlideElement. To check for a substring, you must convert to string first, e.g., `current.short_description.toString().indexOf('urgent') !== -1`. Therefore, the two true statements are A and B.

Answer

The new value of short_description can be accessed using previous.short_description.

Answer

To set the priority, use current.priority.setValue(1).

Answer

The comparison should use current.short_description.indexOf('urgent') !== -1.

Question 3

A developer needs to display a warning message to the user when the 'priority' field is changed to '1 - Critical'. Which TWO client-side implementations can achieve this?

Accepted Answer

UI Policy with condition: 'Priority changes' and action script to call g_form.showFieldMsg(). Option B is correct because a UI Policy with the condition 'Priority changes' triggers an action script when the priority field is modified, allowing the use of `g_form.showFieldMsg()` to display an inline warning message on the field. Option E is correct because an onChange client script fires when the 'priority' field changes, and within it you can check `newValue` against '1 - Critical' and call `g_form.showFieldMsg()` to show the warning. Both are client-side implementations that respond to field changes without a server round-trip.

Answer

Business Rule with 'when to run' set to 'before' and script to call g_scratchpad.message

Answer

onLoad client script that checks the current value of priority and shows a message

Answer

Data Policy with condition on priority field and message set

Question 4

Which TWO of the following are valid ways to personalize a Service Portal widget without modifying the original widget code?

Accepted Answer

Extend the widget via Widget Library. Options A and D are correct because they allow personalization without altering the original widget code. Option A: Extending the widget via the Widget Library creates a copy that inherits from the original, enabling modifications without touching the source. Option D: Widget Instance options permit overriding properties like CSS, Angular providers, or client scripts at the instance level. Option B is incorrect because Business Rules cannot override a widget's server script; server scripts are tightly coupled to the widget and cannot be replaced by a Business Rule. Option C is incorrect because modifying the HTML template directly in the instance alters the original widget code. Option E is incorrect because creating a new widget from scratch is not a method of personalizing an existing widget; it is building a new one.

Answer

Override the widget's server script via a Business Rule

Answer

Modify the widget's HTML template directly in the instance

Answer

Create a new widget from scratch

Question 5

A developer needs to create a catalog item that requires approval from the user's manager. What is the best practice to configure this?

Accepted Answer

Add an 'Approval' activity in the workflow. Option B is correct because adding an 'Approval' activity in a workflow is the standard and best practice for managing approvals in catalog items in ServiceNow. Option A is incorrect because 'Get Approvals' is not a standard action in Flow; Flow does not have a direct 'Get Approvals' action for approval routing. Option C is incorrect because Client Scripts handle client-side behavior and cannot trigger approval requests; approvals are server-side. Option D is incorrect because Business Rules are not designed for approval routing; they are used for server-side logic on tables, not for orchestrating approval processes.

Answer

Use a Flow with a 'Get Approvals' action

Answer

Use a Client Script to trigger an approval request

Answer

Use a Business Rule to set the approval state

Question 6

A developer needs to capture the time when a field (assigned_to) was last changed. Which approach should be used?

Accepted Answer

Create a business rule on 'after' update that sets a 'last_assigned' field when assigned_to changes.. Option B is correct because a business rule running 'after' update can check if the 'assigned_to' field value changed (using previous()) and set a 'last_assigned' field to the current date/time (gs.nowDateTime()). This server-side, platform-native approach reliably captures the timestamp when the field changes. Option A (calculated field) is incorrect because calculated fields are read-only and derive values from other fields; they cannot set a timestamp when a field changes. Option C (database trigger) is not recommended as it bypasses the ServiceNow platform and could cause synchronization issues. Option D (dictionary override to enable auditing) is incorrect because auditing tracks all changes to the field in the audit table but does not store the last change timestamp in a separate field on the record; it would require querying the audit log to find the last change.

Answer

Create a calculated field using a formula.

Answer

Create a database trigger to log the change.

Answer

Use a dictionary override to enable auditing.

Question 7

A developer is creating a REST API endpoint in ServiceNow that must accept JSON payloads and return a response. Which method should be used to parse the incoming request body?

Answer

JSON.parse(request.body)

Question 8

Which TWO are best practices when implementing data integrations using ServiceNow import sets?

Accepted Answer

Schedule the import to run during off-peak hours. Options A and D are correct. A: Scheduling imports during off-peak hours minimizes impact on system performance and user experience. D: Using coalesce in the transform map on a unique field prevents duplicate records by matching existing records based on that field. B is incorrect because REST API is an alternative integration method, not a performance improvement over import sets. C is incorrect because update sets are used to move configurations between instances, not to manage import set configurations. E is incorrect because while staging tables are commonly used, they are not always required for all data sources.

Answer

Use REST API instead of import sets for better performance

Answer

Use update sets to manage import set configurations

Answer

Always use a staging table for all data sources

Question 9

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. The 400 Bad Request error typically indicates malformed request syntax. A common cause is missing or incorrect Content-Type header. For REST API endpoints expecting JSON payload, the Content-Type header must be set to application/json. Option C is correct because without this header, the server cannot parse the request body and returns 400. Option A is wrong because the HTTP method (POST) is often correct for creating data; PUT would be for updates. Option B is wrong because missing authentication would result in 401 Unauthorized, not 400. Option D is wrong because the Accept header controls response format; setting it to text/plain is not required for JSON requests.

Answer

The HTTP method should be PUT instead of POST

Answer

Missing authentication credentials

Answer

The Accept header should be text/plain

Question 10

As a best practice, which method should be used to schedule recurring data imports from external sources?

Accepted Answer

Configure a scheduled job to use the Import Set API or transform. Option C is correct because a scheduled job can be configured to run at recurring intervals and use the Import Set API or transform to import data from external sources. Option A is incorrect because update sets are used for version control and deployment, not for scheduling data imports. Option B is incorrect because a Flow Designer flow with an HTTP trigger is designed for real-time HTTP requests, not for recurring scheduled imports. Option D is incorrect because business rules trigger on database operations (like insert, update, delete) and are not suited for scheduling recurring imports.

Answer

Deploy an update set for each import

Answer

Use a Flow Designer flow with an HTTP trigger

Answer

Create a business rule that triggers on a condition

Question 11

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 B is correct because reviewing each conflict and choosing the correct version allows the developer to selectively merge changes, preserving important modifications while discarding unwanted ones. Option A is wrong because deleting and re-importing disregards the resolution of conflicts and may lose customizations. Option C is wrong because discarding all local changes removes any work done locally without consideration. Option D is wrong because accepting all remote changes may overwrite intentional local customizations.

Answer

Delete the application and re-import.

Answer

Discard all local changes.

Answer

Accept all remote changes.

Question 12

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 E are best practices. Storing credentials in a credential store or using OAuth (option B) enhances security over basic authentication (option C is incorrect). Using HTTPS (option E) encrypts data in transit, protecting it from interception. Option A is wrong because GlideRecordSecure API is actually recommended for secure REST endpoint operations. Option D is incorrect because the sysparm_query parameter filters records but does not limit the number of records returned; use sysparm_limit for that purpose.

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 13

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?

Answer

The client script is set to run on the 'Load' event instead of 'Change'.

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 14

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 D is correct because directly editing system tables outside of the application scope bypasses version control and can cause conflicts, making it not a recommended practice. Options A, B, and C are all recommended practices for version control in ServiceNow Studio.

Answer

Create a new application version for each major release.

Answer

Track changes using update sets.

Answer

Use application scope to isolate changes.

Question 15

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.. The primary issue is that calling gr.update() inside the while loop on the same GlideRecord object causes an infinite loop. When a business rule or trigger runs on update and re-queries the same set of records, gr.next() may keep returning true as newly updated records might still satisfy the query condition. Option A is incorrect because setValue syntax is correct. Option B is incorrect as next() iterates correctly. Option D is a possible secondary effect but not the primary issue.

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 16

Which of the following is a best practice when creating REST API endpoints?

Accepted Answer

Use versioning in the API path.. Versioning the API path (e.g., /api/now/v1/incident) is a best practice to manage changes without breaking existing consumers.

Answer

Use GET methods for data modification.

Answer

Pass sensitive data in URL parameters.

Answer

Return all data without pagination.

Question 17

In ServiceNow Studio, which role is required to create a new scoped application?

Accepted Answer

Admin role. Option D is correct because only users with the admin role can create scoped applications in ServiceNow Studio. Option A is incorrect because a global scope update set is not a role; it is a type of update set. Option B is incorrect because not all users have the ability to create applications; it requires the admin role. Option C is incorrect because the Application Creator role does not exist as a standard role; the admin role is required.

Answer

A global scope update set

Answer

No special role; any user can create applications

Answer

Application Creator role

Question 18

A developer needs to create a record in the 'task' table when a specific condition is met in a Business Rule. The new record should be linked back to the current record via a reference field. What is the best practice to ensure the new record is created in the same transaction?

Accepted Answer

Use GlideRecord with newRecord() and set values, then call insert().. Option A is correct because using GlideRecord with newRecord() and insert() within the same Business Rule ensures the new 'task' record is created in the same database transaction as the current record. This guarantees atomicity: if the insert fails, the entire transaction rolls back, preventing orphaned records. The reference field linking back to the current record is set synchronously before the insert, maintaining data integrity.

Answer

Use Flow Designer to create the record asynchronously.

Answer

Use the GlideRecord updateMultiple() method.

Answer

Call a Scripted REST API to insert the record.

Question 19

A service catalog item has a variable set that includes a reference field to the 'cmdb_ci' table. The requirement is to show only 'Server' type CI's in the reference field. Which approach should be used?

Accepted Answer

Set a Reference Qualifier on the variable definition that uses the condition 'sys_class_name=Server'.. Option B is correct because a Reference Qualifier on a variable definition allows you to filter the records displayed in a reference field using a condition string. By setting the condition 'sys_class_name=Server', only CI records with that specific sys_class_name will appear, which directly meets the requirement to show only 'Server' type CIs.

Answer

Create a UI Policy that sets the field as read-only and uses a condition to filter.

Answer

Write a Client Script on load that sets the reference qualifier using setRefQual().

Answer

Use a Data Policy to enforce a condition on the field.

Question 20

A company has a requirement that the 'state' field of an incident cannot be changed from 'In Progress' to 'Resolved' if the 'category' field is empty. This validation must be enforced server-side to prevent data integrity issues. Which implementation should be used?

Accepted Answer

Create a 'before' Business Rule that checks if the state is changing to 'Resolved' and if category is empty, aborts the update with an error message.. Option D is correct. A 'before' Business Rule runs server-side and can check if the state is changing to 'Resolved' and if the category field is empty. Using gs.addErrorMessage() and returning false aborts the update, enforcing the validation server-side. Option A (Data Policy) would make category mandatory globally, not only during the specified state transition. Option B (ACL) controls field-level access but cannot validate value transitions. Option C (Client Script) runs client-side and can be bypassed.

Answer

Make the 'category' field mandatory using a Data Policy.

Answer

Configure an ACL on the 'state' field to deny write access when category is empty.

Answer

Create a Client Script on 'state' change that checks if category is empty and shows an error message.
