SNOW-CAD Practice Test 19 — 15 Questions

Question 1

A developer is building a custom scoped application for tracking IT assets. The application includes a table named 'u_asset' and a related table named 'u_asset_audit' that extends 'u_asset'. The developer needs to ensure that whenever a record is inserted into 'u_asset_audit', a corresponding record is automatically created in a separate 'u_asset_history' table. The developer writes a Business Rule on 'u_asset_audit' with the 'after insert' timing. However, during testing, the history record is not being created. The developer confirms that the Business Rule is active, the condition is empty, and the script contains no errors. What is the most likely reason the Business Rule is not executing?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

The Business Rule is set to run 'after insert' but the developer is testing by updating an existing record, not inserting a new one.. The correct answer is that the Business Rule is set to run on insert, but the developer is testing by updating a record. Business Rules are operation-specific: an 'after insert' rule only triggers when a new record is inserted. If the developer is updating an existing record, the rule will not fire. This is a frequent mistake when testing Business Rules, as developers may not realize the operation being performed does not match the rule's timing. The other options are incorrect because they either misrepresent ServiceNow capabilities or assume test conditions that contradict the scenario.

Answer

Business Rules on extended tables do not inherit to child tables unless the 'Inherit' check box is selected on the parent table's Business Rule.

Answer

The 'after insert' Business Rule is not triggered because the 'u_asset_audit' table is a child table and ServiceNow does not allow Business Rules on child tables.

Answer

The Business Rule is not executing because the 'u_asset_audit' table does not have any records inserted into it.

Question 2

A developer is creating a new script include in ServiceNow Studio for a scoped application. The script include must be callable from a client script running in the same application. Which setting should the developer configure to allow this?

Accepted Answer

Select the Client callable checkbox on the script include record.. To allow a client script to call a script include, the script include must be marked as client callable. This setting exposes a secure endpoint that client scripts can invoke using GlideAjax. Without this checkbox, the script include remains server-side only, and client scripts cannot execute its methods directly.

Answer

Change the script include's scope to global so that client scripts can access it.

Answer

Add the script include to the application's Client Scripts module.

Answer

Set the script include's Accessible from field to 'All application scopes'.

Question 3

A company is expanding its use of ServiceNow and needs to create a custom application for managing employee onboarding tasks. The application includes several tables: Onboarding Request, Task, and Checklist Items. The business requires that when an onboarding request is submitted, a set of tasks should be automatically created in a specific order. Additionally, when all tasks are completed, the onboarding request status should automatically update to 'Completed'. The developer decides to use Flow Designer to automate this process. The developer creates a flow with a trigger on the Onboarding Request table for 'Record created or updated' and adds actions to create tasks. However, during testing, the flow creates tasks but does not update the request status when tasks are completed. What is the most likely issue?

Accepted Answer

The flow is not configured to listen for updates on the Task table.. The flow is triggered only by events on the Onboarding Request table. To update the request status when tasks are completed, the flow must also listen for updates on the Task table (e.g., via a separate flow or a 'Wait for condition' that polls the Task table). Without a trigger or condition monitoring the Task table, the flow has no way to know when tasks finish.

Answer

The flow is set to run only on create, not on update.

Answer

The flow uses a 'Wait for condition' action that is not configured correctly.

Answer

The user does not have rights to update the Onboarding Request table.

Question 4

A company needs to prevent updates to a field after a record has been in state 'Closed' for more than 30 days. What is the best approach?

Accepted Answer

Use a Business Rule on update with condition state=Closed and days since closed > 30, and abort action when field is being updated.. A Business Rule on update with a condition that checks if the record is in 'Closed' state and the days since closed is greater than 30, and then aborts the update if the field is being modified, is the best approach. This enforces the restriction at the database level, regardless of how the update is attempted (UI, API, import). It ensures that the field cannot be updated after the 30-day period.

Answer

Use a Business Rule on query to check state and field value.

Answer

Use a UI Policy to set field read-only.

Answer

Use a Business Rule with condition when state changes to Closed, set the field to read-only.

Question 5

A dashboard with multiple indicators is loading slowly. The dashboard contains live data from several tables with complex conditions. Which optimization should be applied first?

Accepted Answer

Convert indicators to use aggregated data sources instead of live queries.. Using aggregate indicators reduces the number of live queries by pre-calculating data, which is the most effective optimization for dashboard performance.

Answer

Use client-side scripts to load data asynchronously.

Answer

Reduce the number of indicators to one.

Answer

Increase the cache timeout for all indicators.

Question 6

A company has a ServiceNow instance integrated with a third-party ticket management system. The integration runs every hour via a scheduled job that calls a REST API to fetch new tickets and create incidents in ServiceNow. The administrator notices that some incidents are being created as duplicates. Investigation reveals that the third-party system sometimes returns the same ticket in multiple API calls due to caching. The scheduled job does not check for existing incidents before creating new ones. The administrator needs to modify the integration to prevent duplicate incidents without relying on the third-party system to change its behavior. Which action should the administrator take?

Accepted Answer

Add a check in the integration script to query the incident table for an existing incident with the same external ticket ID before creating a new one.. The most reliable way to prevent duplicates is to check the incident table for an existing record with the same external ticket ID before creating a new incident. This leverages the unique identifier from the third-party system and avoids relying on the third-party's caching behavior. By querying the incident table using a GlideRecord lookup on a field that stores the external ID, the script can conditionally skip creation if a match is found.

Answer

Modify the integration to only create incidents if the ticket status is 'New'.

Answer

Increase the scheduled job interval to run every 2 hours.

Answer

Add a post-processing script that deletes duplicate incidents after each run.

Question 7

A developer is designing a custom form in the standard UI (UI16) and needs to add a message that displays only when the 'state' field is 'Closed'. Which feature should be used to achieve this without custom scripting?

Accepted Answer

Create a UI Policy that adds a message when the condition state=Closed is true.. UI Policies are the correct declarative feature in UI16 to show a message based on a field value without custom scripting. They run on the client side and can display informational, warning, or error messages when a specified condition (like state=Closed) is met, making option A the appropriate choice.

Answer

Create a form section and set its condition via the 'Conditional' property.

Answer

Write a Client Script that shows a message when state changes to Closed.

Answer

Use a UI Macro with a condition that checks the state field.

Question 8

What is the purpose of using the 'Async' option in a business rule?

Accepted Answer

To run the rule in a separate background thread to avoid performance impact.. The 'Async' option in a business rule causes the rule to run asynchronously in a separate background thread, after the database operation completes. This prevents the rule from delaying the user's transaction and avoids performance impact on the user interface. It is used for long-running or resource-intensive logic that does not need to block the user.

Answer

To run the rule immediately after the database operation.

Answer

To run the rule only when the record is viewed.

Answer

To prevent the rule from running on updates.

Question 9

Which TWO of the following are valid types of client scripts in ServiceNow? (Choose two.)

Accepted Answer

onSubmit. B. onSubmit is a valid client script type in ServiceNow: it runs on the client when a form is submitted, before the record is sent to the server, and is commonly used for client-side validation (returning false aborts submission). C. onChange is also a valid client script type: it fires when the value of a specified field changes on a form, enabling dynamic UI behavior such as showing/hiding fields or setting other field values. The other options are not client script types: onDelete and onUpdate are server-side business rule timings (before/after delete and update), while onClick is not a ServiceNow client script type (UI Actions handle click behavior). Therefore only onSubmit and onChange belong to the list of valid client script types.

Answer

onDelete

Answer

onClick

Answer

onUpdate

Question 10

A user needs to generate a report that shows the count of incidents by category for the current month. Which table and field combination should be used in a report?

Accepted Answer

Use the 'incident' table with 'category' and 'sys_created_on'.. The incident table contains incident records, and the category field allows grouping incidents by category, while sys_created_on can be used to filter incidents created in the current month. Option A is incorrect because the cmdb_ci table is for configuration items, not incidents. Option B is incorrect because the task table includes multiple task types (incidents, problems, changes), so it's not specific to incidents. Option C is incorrect because the sys_user table stores user information, not incidents.

Answer

Use the 'cmdb_ci' table with 'install_status' and 'sys_created_on'.

Answer

Use the 'task' table with 'priority' and 'sys_updated_on'.

Answer

Use the 'sys_user' table with 'department' and 'sys_created_on'.

Question 11

A Service Portal widget is failing to update a reference field on a form after a user selects a value from a reference picker. The developer reviews the widget's client controller and sees the following code snippet: $scope.c.data.selectedItem = value; The server script expects 'selectedItem' to be a sys_id string, but it is receiving an object. What is the most likely cause?

Accepted Answer

The reference field returns an object with 'value' and 'display' properties; the code should extract the sys_id.. When a reference picker returns a value in Service Portal, it typically provides an object containing both the display value and the sys_id (e.g., {value: 'sys_id', display: 'name'}). The client controller code assigns this entire object to $scope.c.data.selectedItem, but the server script expects a plain sys_id string. The developer must extract the sys_id property (e.g., value.sys_id or value.value) before assigning it to the scope variable.

Answer

The server script expects the parameter in a different scope variable, like $scope.c.data.item.

Answer

The $scope.c.data assignment is incorrect; it should be $scope.data.

Answer

The client controller is not allowed to set $scope.c variables.

Question 12

A developer is designing a dashboard for a service desk manager. The dashboard must show the count of open incidents by assignment group and allow the manager to click a group to drill into the filtered incident list. The dashboard should refresh automatically every five minutes. Which combination of features should the developer use?

Accepted Answer

A Platform Analytics dashboard with a Bar Chart visualization grouped by assignment group, configured with a drill-down to the filtered Incident list and an auto-refresh interval of five minutes.. A Platform Analytics dashboard with a bar chart grouped by assignment group provides the grouped counts and supports configuring each segment to drill down into the filtered Incident list. Setting an auto-refresh interval of five minutes keeps the visualization current. Gauges, plain embedded reports, and Performance Analytics scorecards each fall short on interactive per-group drill-down or immediate timed refresh.

Answer

A Performance Analytics dashboard with a scorecard for open incidents and a scheduled data collection job every five minutes.

Answer

A report on the Incident table grouped by assignment group, added to the dashboard, with the dashboard set to run the report on a five-minute schedule.

Answer

A home page gauge with a single aggregate count of open incidents and a UI Action to open the incident list.

Question 13

A developer needs to create a REST integration that retrieves data from an external system and displays it in a ServiceNow custom widget. The external API requires OAuth 2.0 authentication. Which ServiceNow feature should the developer use to securely store and manage the OAuth credentials?

Accepted Answer

OAuth 2.0 provider and application registry records to configure the connection and credentials.. For OAuth 2.0 integrations, ServiceNow provides the OAuth provider and application registry, which securely store client credentials and manage token acquisition and refresh. These records integrate with outbound REST messages, allowing the developer to authenticate without handling secrets in scripts. This is the recommended and secure approach for external API authentication.

Answer

System Properties for storing the client ID and client secret as plain text.

Answer

A custom table with encrypted fields to store the credentials manually.

Answer

Credentials stored in the MID Server's config.xml file and accessed via a script.

Question 14

A developer creates a business rule on the Incident table that executes a GlideRecord query to update related records. The rule runs on 'after' update and queries the Problem table to set a field. However, the update is not being committed. What is the most likely reason?

Accepted Answer

The GlideRecord query requires an explicit gr.updateMultiple() or gr.commit() to persist changes.. In ServiceNow, when a GlideRecord query is used in an 'after' business rule to update records on another table, the changes are not automatically committed. The developer must explicitly call gr.updateMultiple() to persist updates to multiple records, or gr.update() for a single record. Option B correctly identifies this requirement, as the update is not being committed without an explicit method call.

Answer

The developer forgot to use gr.insert() instead of gr.update().

Answer

After business rules cannot update other tables.

Answer

The query returns more than 100 records, causing a governor limit.

Question 15

A developer is building a scoped application in ServiceNow Studio. The application must send a notification to the assignment group when a critical incident is created. Which application file type should the developer create to accomplish this?

Accepted Answer

Notification. Notifications are designed to send messages based on record events, such as insert or update. They are configured with conditions, recipients, and content. In a scoped application, creating a Notification through Studio ensures it is part of the application package. This declarative approach is preferred over custom scripting because it is easier to maintain and leverages built-in functionality.

Answer

UI Action

Answer

Script Include

Answer

Business Rule
