Which TWO of the following are valid ways to trigger a business rule? (Choose two.)

Which THREE of the following are best practices when writing business rules? (Choose three.)

A ServiceNow administrator notices that a business rule designed to update the 'short_description' field on the 'incident' table is not executing when a user changes the field via a custom UI page that uses GlideRecord. The script in the business rule uses current.setValue() and current.update(). What is the most likely cause?

Which TWO statements are true about using GlideAggregate in business rules?

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?

A ServiceNow developer needs to implement a business rule that automatically sets the 'state' field to 'In Progress' when a user is assigned to an incident. The rule should run only when the 'assigned_to' field changes, and should not run on any other updates. Which condition type and condition script should be used?

Refer to the exhibit. The business rule is intended to update the CI's operational status when an incident is resolved. However, the CI is not being updated. What is the most likely reason?

In a large enterprise environment, the ServiceNow instance is heavily customized. A business rule on the Change Request [change_request] table runs on after update to initiate a complex workflow involving multiple approvals and updates to Configuration Items (CIs). Recently, the IT operations team noticed that the workflow fails to start for many change requests. The system logs show the error: "Business rule script error: Cannot read property 'sys_id' of null". The developer inspects the business rule script and sees the following code snippet: var task = new GlideRecord('task'); task.get(current.sys_id); var relatedCI = task.cmdb_ci; // The rest of the script uses relatedCI to update the CI's status. The developer knows that change requests are not stored in the task table; they are in change_request. However, the script was written by a previous developer and has been working for months. The developer must fix the script to ensure the workflow starts correctly. Which action should the developer take?

A mid-sized company heavily relies on ServiceNow for incident management. They have a business rule that runs before insert on the Incident table. The rule dynamically sets the assignment group based on the category of the incident and the location of the caller. To determine the correct group, the script performs a GlideRecord query against a custom table called "u_group_mapping", which contains approximately 5000 records mapping category-location pairs to groups. During peak business hours, when many incidents are created simultaneously, the business rule causes significant delays and occasional timeouts, impacting user experience. The development team has been tasked with optimizing this business rule without changing its functionality. The current script structure is roughly: (function executeRule(current, previous) { var gr = new GlideRecord('u_group_mapping'); gr.addQuery('category', current.category); gr.addQuery('location', current.caller_id.location); gr.query(); if (gr.next()) { current.assignment_group = gr.assignment_group; } })(current, previous); The team wants to reduce the database access overhead. Which optimization technique should the developer implement?

A small IT department uses ServiceNow for incident management. They have a business rule that runs after insert on the Incident table. The rule is intended to send an email notification to the assignment group whenever a new incident is created. The rule uses a standard "send event" method, and the email notification is set up in the system mail properties. Recently, the group leader noticed that some incidents are not triggering emails. The developer investigates the business rule and confirms that the script executes without errors, but the email is not sent for those specific incidents. The developer checks the email notification configuration and finds that it is set to send to the "assigned user" rather than the "assigned group". After correcting this, the emails start working. However, the developer wants to understand why only some incidents were affected. Which of the following best explains the issue?

A ServiceNow instance has a business rule named 'Update CI Status' that runs on the 'Change Request' table after insert. The rule is intended to update the 'Configuration Item' record's 'Operational Status' to 'Under Maintenance' when a change request is created. The business rule uses the following script: (function executeRule(current, previous != null)) { var gr = new GlideRecord('cmdb_ci'); gr.get(current.cmdb_ci); gr.operational_status = 'Under Maintenance'; gr.update(); })(current, previous); After a recent upgrade to the Vancouver release, the business rule stopped working. The change request is created successfully, but the CI's operational status remains unchanged. The system logs show no errors. What is the most likely cause and the correct fix? A. The business rule is running asynchronously; change it to synchronous. B. The condition field is empty; add 'gs.action() === 'insert'' as the condition. C. The 'current.cmdb_ci' field is not populated; check that the field is required on the form. D. The script uses 'previous' incorrectly; remove 'previous != null' from the function signature.

A senior developer has created a complex business rule called 'Asset Assignment' on the 'alm_asset' table that runs after insert. The rule queries the 'User' table to find a manager and assigns the asset to that manager's department via a GlideRecord update. The rule has an order of 100. Another business rule called 'Asset Log' on the same table also runs after insert with an order of 200, which logs the assignment in a separate table. After deploying to production, the 'Asset Log' rule executes but the assignment update from 'Asset Assignment' fails silently. The developer discovers that the 'Asset Assignment' rule has a condition script that references a new field that was not added to the 'alm_asset' table in production. The field exists in the developer's instance but not in production. The developer wants to minimize disruption and fix the issue quickly. Which action should the developer take? A. Change the condition script to check if the field exists before using it, and if not, exit the script gracefully. B. Reorder the business rules so that 'Asset Log' runs first and 'Asset Assignment' runs second, and add a condition to 'Asset Log' to only run if the assignment succeeded. C. Remove the condition from 'Asset Assignment' and move the field existence check into the script, setting the field value only if it exists. D. Deactivate the 'Asset Assignment' business rule until the field is added to the table in production, then reactivate it after the next maintenance window.

A company has a business rule that should update the 'priority' field on the Incident table whenever the 'impact' field is changed to 'High'. However, the business rule is not firing. The business rule is set to run 'before' insert/update, with condition 'current.impact.changes()'. The 'impact' field is of type 'choice' with values 'Low', 'Medium', 'High'. Which of the following is the most likely cause?

Which two of the following are best practices when writing Script Includes in ServiceNow? (Choose two.)

Refer to the exhibit. The script runs as a business rule on the incident table. What will happen when this script executes?

You are a ServiceNow administrator for a large organization that uses a custom application to manage IT assets. The application has a business rule on the 'asset' table that runs 'after update' and logs changes to a separate audit table. Recently, users have reported that saving an asset record takes over 30 seconds, and the system performance has degraded. Upon investigation, you find that the business rule contains a GlideRecord query that retrieves all related asset history records for each update, and then performs additional calculations. The asset table has over 500,000 records, and each asset has an average of 50 history records. The business rule is triggered on every field update, including minor changes like last modified date. You need to improve the response time without losing the audit functionality. Which course of action should you take?
