SNOW-CAD Practice Test 2 — 25 Questions

Question 1

A UI Macro on a form is causing slow load times. The macro uses multiple GlideRecord queries in its server-side script. The developer wants to optimize performance without altering functionality. Which action is most effective?

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

Accepted Answer

Replace GlideRecord queries with GlideAggregate and cache the results. Replacing multiple GlideRecord queries with a single GlideAggregate query reduces the number of database calls, improving performance. Caching the results further avoids redundant queries. Option A is incorrect because asynchronous loading does not reduce the total server processing. Option B is incorrect because moving queries to a client script via GlideAjax only shifts the load but still requires server-side processing. Option C is incorrect because g_form.addOption() is for adding options to a select field, which does not address the macro's performance issue.

Answer

Load the macro asynchronously using UI Macro configuration

Answer

Move the queries to a client script using GlideAjax to reduce server load

Answer

Use g_form.addOption() to populate a reference field instead of building the macro

Question 2

A business rule updates a field on the incident table after submission. However, the updated value is not displayed on the form when the record is opened again. What is the most likely cause?

Accepted Answer

A client script (onLoad) is setting the field back to its original value.. A client script (onLoad) can run after the record is opened and set the field back to its original value, overriding the value updated by the business rule. Option A is incorrect because the form does refresh when the record is opened, so the issue is not a lack of refresh. Option B is incorrect: asynchronous business rules still save their updates to the database; the timing of execution does not affect whether the value persists on the form. Option D is incorrect because hiding a field via UI Policy does not change its value; the value would still be stored.

Answer

The form is not refreshing after submission.

Answer

The business rule is set to run asynchronously.

Answer

A UI Policy is hiding the field.

Question 3

A UI Macro that displays a custom header is not appearing on the form. The macro is referenced in a UI16 theme. What is the first troubleshooting step?

Accepted Answer

Examine the UI Macro record for syntax errors in the HTML or Jelly script.. The first troubleshooting step is to examine the UI Macro record for syntax errors in the HTML or Jelly script (Option D). Syntax errors are the most common cause of a macro not rendering. Checking the browser's HTML source (A) is possible but not the first step. Ensuring the UI Macro is in global scope (B) is less likely the issue, as macros are typically accessible within the theme. Verifying UI Scripts (C) is unrelated because UI Scripts are separate client-side resources, not the macro's own code.

Answer

Check the browser's HTML source for the macro's placeholder.

Answer

Ensure the UI Macro is in the global scope.

Answer

Verify that all referenced UI Scripts are loaded.

Question 4

Refer to the exhibit. After creating this database view, the view contains fewer records than the sum of records in incident and problem tables. What is the most likely cause?

Accepted Answer

UNION should be UNION ALL to retain duplicate rows. The UNION operator by default removes duplicate rows. If there are overlapping records between the incident and problem tables (e.g., same sys_id, number, or short_description), UNION eliminates them, resulting in fewer records than the sum of the two tables. Using UNION ALL would retain all rows, including duplicates. Option A is incorrect because the 'active' field is not required for the view to include all records. Option C is false because database views can combine records from multiple tables. Option D is incorrect because DISTINCT is already implied by UNION and would further reduce rows, not increase them.

Answer

The view must include the 'active' field from both tables

Answer

A database view cannot combine records from incident and problem tables

Answer

The SELECT statement should include DISTINCT

Question 5

Which THREE statements are true about database views in ServiceNow?

Accepted Answer

Database views can have fields from multiple tables. Options A, C, and D are correct. Database views are read-only (D), can combine fields from multiple tables (A), and can be used as a source for reports (C). Option B is false because database views cannot reference tables from different instances or databases; they can only combine tables within the same instance. Option E is false because database views are read-only and cannot be updated via business rules.

Answer

Database views can reference tables from different instances or databases

Answer

Database views can be updated via business rules

Question 6

Which TWO actions can be performed directly from ServiceNow Studio?

Accepted Answer

Configure form layout.. Options C and D are correct because ServiceNow Studio provides functionality to create new tables and configure form layouts. Option A is incorrect because configuring email notifications is done in the System Notifications module, not in Studio. Option B is incorrect because running scheduled jobs is managed in the Scheduled Jobs module. Option E is incorrect because defining workflows is done in the Workflow Editor, not in Studio.

Answer

Configure email notifications.

Answer

Run a scheduled job.

Answer

Define a workflow.

Question 7

A developer wants to send an email notification when a new incident is created. Which component should be configured to trigger the notification?

Accepted Answer

Create a Notification record with the condition 'New' and 'Action: record inserted'.. In ServiceNow, the native Notification mechanism is specifically designed to send emails based on conditions like 'New' and 'Action: record inserted'. When a new incident is created, the system evaluates the notification's condition; if it matches, the notification triggers automatically without requiring custom scripting or flow design. This is the standard, out-of-box approach for email alerts on record creation.

Answer

Use Flow Designer to create a flow that sends an email.

Answer

Write a Business Rule that calls the email utility.

Answer

Create an ACL with email action.

Question 8

A developer is designing a data architecture for a multi-tenant environment where each company's data must be isolated. Which TWO strategies can achieve this? (Choose two.)

Accepted Answer

Implement domain separation.. Options A and E are correct. Domain separation (A) provides built-in data isolation by partitioning data based on domains, ensuring each company sees only its own data. Separate tables for each company (E) physically isolate data at the database level. Option B (ACLs) adds security but does not inherently isolate data in a multi-tenant architecture. Option C (database views) filters data but does not enforce isolation at the application layer. Option D (GlideRecord conditions) relies on developer discipline and is not a robust architectural solution.

Answer

Use access control lists (ACLs) on each record.

Answer

Create database views that filter data by company.

Answer

Add a condition to every GlideRecord query to filter by company.

Question 9

Drag and drop the steps to create a new application in ServiceNow Studio into the correct order.

Accepted Answer

Access Application Creator, then Initiate wizard, then Provide application details, then Choose template, then Create application. The correct sequence starts with accessing the Application Creator, then initiating the wizard, providing application details, choosing a template, and finally creating the application.

Answer

Access Application Creator, then Initiate wizard, then Choose template, then Provide application details, then Create application

Answer

Initiate wizard, then Access Application Creator, then Provide application details, then Choose template, then Create application

Answer

Access Application Creator, then Provide application details, then Initiate wizard, then Choose template, then Create application

Question 10

A company requires that when the 'state' field on an incident is set to 'Resolved', the 'resolution_code' field must be populated. Which mechanism should be used to enforce this rule?

Accepted Answer

Data policy with condition state = 'Resolved' and mandatory resolution_code.. Data policies enforce field requirements on server-side updates and apply regardless of how the record is updated (UI, web services, etc.). In this scenario, a data policy with condition state='Resolved' and mandatory resolution_code ensures that the field must be populated when the state is set to Resolved. Option A (client script) is client-side only and can be bypassed. Option B (UI policy) is also client-side only. Option C (business rule) could be used to enforce the requirement, but data policy is the recommended mechanism for field-level validation because it is simpler and automatically handles all server-side operations. Therefore, option D is correct.

Answer

Client script that checks the state and pops up a message.

Answer

UI policy that sets the resolution_code field mandatory.

Answer

Business rule with a condition on state change.

Question 11

Refer to the exhibit. A transform map configuration is shown. What will happen if the source data has a 'u_model_id' value that matches an existing record in the 'cmdb_ci_model' table?

Accepted Answer

The transform will automatically set the model_id reference to the existing model record.. When coalesce is set to true on a reference field like 'model_id', the transform engine uses the source value (u_model_id) to look up an existing record in the referenced table (cmdb_ci_model). If a matching record is found, the transform sets the reference field to that existing record without creating a new one. Option A is incorrect because coalesce does not ignore the field; it actively searches for a matching record. Option B is incorrect because coalesce does not create new records; it only matches existing ones. Option D is incorrect because the transform does not skip the record; it proceeds with the transformation, setting the reference to the existing model.

Answer

The transform will ignore the field because it is already mapped.

Answer

The transform will create a new model record with the given value.

Answer

The transform will skip the record because the model already exists.

Question 12

A developer is writing a business rule that should run on after update of the Incident table to send an email notification when the state changes. The developer uses the method current.state.changes() to detect the change. However, the email is sent multiple times for the same incident update. What are two possible reasons? (Choose two.)

Accepted Answer

The email notification is triggered by a different business rule. Duplicate emails on the same incident update occur when multiple business rules send the notification or when the same rule runs multiple times. Option D is correct: another business rule may also be configured to send an email on state change, causing duplicates. Option E is correct: if the business rule runs on both before and after update, it will execute twice for the same update, sending two emails. Option C is incorrect because running on insert causes an additional email on insert, not multiple emails during a single update operation. Option A is incorrect because current.state.changes() properly detects state changes; the issue is not about checking the previous state. Option B is incorrect because setting the condition field to 'state changes' would actually help filter, not cause duplicates.

Answer

The business rule is set to run on every update, but the script does not check the previous state

Answer

The business rule's condition field is set to 'state changes'

Answer

The business rule runs on both insert and update

Question 13

Drag and drop the steps to create an ACL (Access Control List) in ServiceNow into the correct order.

Accepted Answer

Navigate to ACLs, then create a new ACL record, then define the type, operation, and name, then set the condition, then submit.. The sequence: navigate to ACLs, create new, define type/operation/name, set condition, and submit.

Answer

Define the type, operation, and name, then navigate to ACLs, then create a new ACL record, then set the condition, then submit.

Answer

Set the condition, then navigate to ACLs, then create a new ACL record, then define the type, operation, and name, then submit.

Answer

Create a new ACL record, then navigate to ACLs, then define the type, operation, and name, then set the condition, then submit.

Question 14

An organization needs to import data from a SaaS application that provides a CSV file accessible via a direct URL. Which data source type should be configured?

Accepted Answer

File data source. A File data source can import data from a CSV file accessible via a direct URL. Option A is wrong because a REST data source is used for web services, not direct file URLs. Option B is wrong because a JDBC data source connects to SQL databases. Option D is wrong because an LDAP data source is used for directory services.

Answer

REST data source

Answer

JDBC data source

Answer

LDAP data source

Question 15

An organization uses an LDAP integration to import user accounts into ServiceNow. The integration creates a large number of users, but some users are missing their manager field. The manager field in LDAP is a distinguished name (DN). The transform map uses a reference field mapping with "Display value" unchecked. The target field "manager" on sys_user is a reference to sys_user. The import set log shows no errors for those records. What is the most likely cause?

Accepted Answer

The LDAP DN values do not match the sys_id of the manager users.. The manager field is a reference to sys_user. When mapping an LDAP DN (distinguished name) to a reference field with 'Display value' unchecked, the system expects a sys_id or a value that can be matched via a reference qualifier. Since the DN is not a sys_id and no other matching logic is applied, the mapping fails silently, leaving the field empty. The import set log shows no errors because the transformation completes but the field is not populated.

Answer

The transform map's "Coalesce" field is set on manager.

Answer

The import set's "On Conflict" setting is set to "Ignore".

Answer

The manager field in LDAP is empty for some users.

Question 16

A developer wants to add a new field to a table that is part of a scoped application. What is the correct method in Studio?

Accepted Answer

Create a new field in the application's schema.. In a scoped application, the proper method to add a new field is to create it in the application's schema within Studio. Option A is incorrect because right-clicking a table does not provide an 'Add Field' option. Option C is incorrect because Application Builder is used for building applications, not adding fields directly. Option D is incorrect because System Definition > Tables is for global tables, not scoped application tables.

Answer

In Studio, right-click the table and select 'Add Field'.

Answer

Use the Application Builder to add a table extension.

Answer

Navigate to System Definition > Tables and add the field.

Question 17

Which THREE of the following are correct statements about Service Portal client controllers?

Accepted Answer

They can use AngularJS services like $http and $timeout.. Service Portal client controllers are AngularJS controllers that run in the browser. They can use standard AngularJS services such as $http for making AJAX calls to external APIs or the instance, and $timeout for delaying execution, which are both injected as dependencies.

Answer

They run on the server and are called via server-side includes.

Answer

They must define a $scope variable explicitly to bind data to the template.

Question 18

Which TWO application file types can be exported as XML from Studio?

Accepted Answer

Business Rules. Options A and D are correct because Business Rules and UI Policies are standard application files that can be exported as XML from Studio. Option B (Reports) is wrong because Reports are not application files; they are stored separately. Option C (System Properties) is wrong as they are configuration items, not exported via Studio. Option E (Homepages) is wrong because Homepages are not application files and cannot be exported as XML from Studio.

Answer

Reports

Answer

System Properties

Answer

Homepages

Question 19

Which TWO approaches are valid for importing data from an external database into ServiceNow on a recurring basis? (Choose two.)

Accepted Answer

Set up a MID Server to run a scheduled transform map from an external SQL query.. A MID Server can execute a scheduled SQL query against an external database and then run a transform map to map the retrieved data into ServiceNow tables. This approach is a standard pattern for recurring data imports using the MID Server's JDBC capabilities combined with scheduled import sets.

Answer

Use a REST API with a periodic flow that calls an external endpoint.

Answer

Write a business rule that triggers on an external event via web service.

Answer

Use an email inbound action to parse CSV attachments from the external system.

Question 20

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?

Accepted Answer

The client script is set to run on the 'Load' event instead of 'Change'.. The most likely reason because client scripts that need to react to a condition change must be set to run on 'Change' event rather than 'Load'. If the script runs only on 'Load', it executes once when the form loads and will not re-run when the condition changes, so the field remains visible. Option B is incorrect because the API for hiding fields (e.g., g_form.setVisible) is not deprecated. Option C is incorrect because client scripts do not have a 'Run As' role; that applies to server-side scripts. Option D is incorrect because client scripts can access any field present on the form regardless of the field's scope.

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.
