SNOW-CAD Practice Test 3 — 10 Questions

Question 1

A developer creates a script include named 'Utils' with a function that uses gs.log('message'). When called from a business rule on the incident table, the log is written. However, when called from a scheduled job in the same scope, no log appears. What could be the reason?

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

Accepted Answer

The script include is not global.. If the script include is not global (i.e., it is scoped to a specific application), it may not be accessible from all execution contexts. Even though the scheduled job is defined in the same scope, scheduled jobs can run under a different context (such as the global scope) or have additional restrictions that prevent access to non-global script includes. This explains why the business rule works (as it runs in the application scope) but the scheduled job does not. Option A is incorrect because log level settings do not affect script include accessibility—they control whether log messages are displayed. Option B is incorrect because the scenario states the scheduled job is in the same scope. Option D is incorrect because user context does not affect script include visibility; it affects record access.

Answer

The scheduled job's log level is set to 'errors only'.

Answer

The business rule runs in the same scope but the scheduled job runs in a different scope.

Answer

The scheduled job runs with a different user context.

Question 2

Which TWO actions are valid for handling errors in a Flow Designer integration action? (Choose two.)

Accepted Answer

Configure the action to log error details to a local log table.. Correct: A and B. Option A is valid because Flow Designer allows logging error details to a local log table for troubleshooting. Option B is valid because you can use an 'if' condition to check the HTTP status code and branch to handle errors accordingly. Option C is incorrect because returning an error code as a flow variable does not handle the error; it only passes the value. Option D is incorrect because sending an email notification is a separate action, not an error handling action within the integration step. Option E is incorrect because automatic retry requires explicit configuration; it is not enabled by default.

Answer

Return a specific error code as a flow variable.

Answer

Send an email notification to the system administrator using a notification action.

Answer

Set the action to automatically retry on failure without configuration.

Question 3

A company needs to integrate ServiceNow with an external HR system using REST API. The HR system requires OAuth 2.0 client credentials grant. Which ServiceNow application should be used to configure this integration?

Accepted Answer

REST API Message. REST API Message is the dedicated ServiceNow application for defining and managing outbound REST integrations, including OAuth 2.0 client credentials grant. It allows you to configure the authentication profile, endpoint URL, HTTP method, and request/response handling in a structured, reusable way, making it the appropriate choice for integrating with an external HR system via REST API.

Answer

REST API Explorer

Answer

Flow Designer

Answer

IntegrationHub

Question 4

A developer writes a business rule to run on 'before' update of the Incident table. The rule sets a short description only if it is empty. However, the short description is never set even when it's empty. What is the most likely cause?

Accepted Answer

The developer used gs.setValue() instead of current.setValue().. In ServiceNow business rules, `gs.setValue()` is a GlideSystem method that does not exist for setting field values on the current record. The proper method is `current.setValue()`, which directly modifies the field on the current GlideRecord object. Using `gs.setValue()` would result in no change to the short description, even if the condition is met.

Answer

The business rule runs after the database update.

Answer

The condition 'short_description IS EMPTY' is evaluated on the old value.

Answer

The business rule is set to run on insert only.

Question 5

A developer needs to share a custom table from a scoped application with another application. What is the best practice in Studio?

Accepted Answer

Create a cross-scope privilege.. Cross-scope privileges are the standard way to share tables between scoped applications in ServiceNow. Option A is incorrect because there is no 'Accessible from' field on tables. Option B is incorrect because exporting/importing XML is a one-time transfer, not a real-time sharing method. Option D is incorrect because web services are not the best practice for table sharing; cross-scope privileges provide simpler and more integrated access.

Answer

Set the table's 'Accessible from' field to include the other application scope.

Answer

Export the table definition as XML and import into the other application.

Answer

Use a web service to expose the table data.

Question 6

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?

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 7

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 8

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 9

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 10

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
