SNOW-CAD Practice Test 17 — 15 Questions

Question 1

A Service Portal widget is not rendering on the page, and the browser console shows: 'Uncaught ReferenceError: sp is not defined'. The widget's client script uses 'sp.get()'. What is the cause?

Accepted Answer

The widget's client controller does not include 'sp' in the dependency list. The user sees an error 'sp is not defined' because the client script uses 'sp.get()' but 'sp' is not available. In Service Portal, the 'sp' API must be explicitly injected into the widget's client controller. If it is not listed in the dependencies of the client controller function, the script will not have access to 'sp'. Therefore, Option B is correct. Option A is incorrect because the order of widgets on the page does not affect dependency injection for individual widgets. Option C is incorrect because 'angular' is not required for 'sp'; it is the Service Portal API that needs to be injected. Option D is incorrect because there is no race condition; the server script runs first and does not affect the client-side dependency injection.

Answer

The widget is placed before the 'sp' provider widget on the page

Answer

The widget is missing a dependency on 'angular'

Answer

The server script runs after the client script, causing a race condition

Question 2

A developer sees the above error in the browser console when an incident form loads. What is the most likely cause?

Accepted Answer

The onLoad client script uses GlideRecord, which is not available client-side.. The onLoad client script runs on the client side, where GlideRecord is not available. Using it directly in a client script causes the 'gliderecord is not defined' error. Option A is wrong because server-side scripts can use GlideRecord without error. Option C is wrong because 'GlideRecord' is spelled correctly. Option D is wrong because GlideRecord is not deprecated.

Answer

The onLoad client script is running on the server instead of the client.

Answer

The script uses a typo: 'GlideRecord' should be 'GlideRecord'.

Answer

GlideRecord has been deprecated and replaced by a newer API.

Question 3

A UI Policy with the above condition script never evaluates to true. What is the issue?

Accepted Answer

The script should not be wrapped in a function; it should directly be the condition expression.. UI Policy condition scripts are evaluated as expressions; they should directly return the condition result without being wrapped in a function. The script must be a single expression that evaluates to true or false. Option A is incorrect because UI16 does not require AngularJS for UI Policy conditions; UI Policy conditions are still evaluated as standard scripts. Option B is incorrect because there is no evidence of a misspelling, and property names can contain dots. Option C is incorrect because gs.getProperty() is permitted and commonly used in UI Policy scripts.

Answer

The condition must be written in AngularJS to work in UI16.

Answer

The property name is misspelled as 'my.property' but should be 'my_property'.

Answer

gs.getProperty() is not permitted in UI Policy scripts.

Question 4

A ServiceNow developer has created a custom UI page using the 'UI Page' module. The page is accessible via a direct URL, but when the user navigates to it, the page appears blank with no errors in the browser console. What is the most likely cause?

Accepted Answer

The 'Requires role' ACL restricts the page content from rendering for the user. A blank UI page without console errors often indicates that the page’s content is suppressed by a security restriction, such as a required role ACL that the user does not have. Since there are no errors, the page is being reached but the content is not rendered. Option A is incorrect because an undeployed client script would cause a client-side script error, not a completely blank page with no console errors. Option C is incorrect because if the page were not set as ‘Published,’ it would typically show an authorization error rather than a blank page. Option D is incorrect because the processing type (direct vs. producer) affects how the page is called but does not cause a blank page when the page is accessed directly.

Answer

The page references an undeployed client script that fails silently

Answer

The page is not set as 'Published' in the UI Page configuration

Answer

The page is using the 'direct' processing type instead of 'producer'

Question 5

A company is importing data from a CSV into the 'cmdb_ci' table using an Import Set Row transform map. After running the import, some records were not created. The transform map has a 'Coalese' field set to true on the 'name' field. What is the most likely reason for records not being created?

Accepted Answer

The 'Coalese' field is set to true on the 'name' field, so existing records are updated instead of new ones created.. Coalese=true on name means if a record with the same name exists, it will update instead of insert. If the name matches an existing record, no new record is created. Option A is wrong because missing fields trigger errors, not silent failure. Option C is wrong because field mapping issues cause different problems. Option D is wrong because coalesce is for matching, not data type.

Answer

The transform map has incorrect field mappings for the CSV columns.

Answer

The target table has a data policy that prevents insert from import sets.

Answer

The CSV file has missing fields that are mandatory on the target table.

Question 6

A developer needs to create a custom UI page in ServiceNow. Which TWO methods can be used to achieve this? (Choose two.)

Accepted Answer

Build a Service Portal widget and embed it in a portal page. The correct answers are B and E. Option E: A UI Page record can be created directly in the 'UI Pages' module, which generates a server-side Jelly script. Option B: Service Portal widgets are a modern approach to building UI components that can be embedded in portal pages, effectively creating custom UI. Option A is incorrect because client scripts run on the client side and do not create UI pages; they manipulate existing pages. Option C: UI Macros are reusable Jelly snippets, not standalone pages. Option D: Adding a section to an existing form modifies the form layout, not creates a new UI page.

Answer

Write a client script that renders HTML dynamically

Answer

Define a UI Macro and include it in a form

Answer

Add a new section to an existing form layout

Question 7

A company needs to retrieve all active users whose department is 'Sales' and who have a manager assigned. They are using GlideRecord. Which script will correctly accomplish this?

Accepted Answer

var gr = new GlideRecord('sys_user'); gr.addQuery('active', true); gr.addQuery('department', 'Sales'); gr.addQuery('manager', 'ISNOTEMPTY'); gr.query();. It correctly adds queries for active = true, department = 'Sales', and manager ISNOTEMPTY, then executes query() to retrieve all matching records. Option A is incorrect because getRow() is not a valid GlideRecord method. Option C lacks the manager condition. Option D incorrectly uses get() which retrieves a single record by sys_id, not a query.

Answer

var gr = new GlideRecord('sys_user'); gr.addQuery('active', true); gr.addQuery('department', 'Sales'); gr.addQuery('manager', 'ISNOTEMPTY'); var rows = gr.getRow();

Answer

var gr = new GlideRecord('sys_user'); gr.addQuery('active', true); gr.addQuery('department', 'Sales'); gr.query();

Answer

var gr = new GlideRecord('sys_user'); gr.get('active', true); gr.get('department', 'Sales'); gr.get('manager', 'ISNOTEMPTY');

Question 8

A developer needs to filter a list of records based on a reference field condition using a reference qualifier. Which method is used to define a reference qualifier on a dictionary entry?

Accepted Answer

Reference qual. Reference qualifiers are defined in the 'Reference qual' field on the dictionary entry to filter records based on a reference field condition. Option A is incorrect because 'Reference specification' is used for setting the reference table, not for filtering with a qualifier. Option B is incorrect because 'Default value' sets a default value for the field, not a filter. Option D is incorrect because 'Dependent fields' are used to define field dependencies, not reference qualifiers.

Answer

Reference specification

Answer

Default value

Answer

Dependent fields

Question 9

Which TWO methods are valid for adding a condition to a GlideRecord query? (Choose two.)

Accepted Answer

addQuery. Options B and C are correct. addQuery is the standard method for adding an AND condition to a GlideRecord query. addOrCondition is a valid method for adding an OR condition. Option A is wrong because addAndCondition is not a valid GlideRecord method. Option D (setCondition) is not a valid method. Option E (addWhere) is not a valid method.

Answer

addAndCondition

Answer

setCondition

Answer

addWhere

Question 10

A developer needs to update a large number of records in the 'incident' table based on a specific condition. Which approach should be used to minimize performance impact?

Accepted Answer

Use GlideRecord with setWorkflow(false) and setEngine(false) to update records in a loop.. A is correct because using GlideRecord with setWorkflow(false) and setEngine(false) prevents unnecessary business rules and workflow execution, reducing performance impact. B is incorrect because GlideAggregate is used for aggregation and statistics, not for updating records. C is incorrect because an export set is designed for data export/import, not for bulk updates within the platform. D is incorrect because updateMultiple does perform bulk updates but still triggers business rules if not disabled, and it does not provide the same level of control as GlideRecord with disabled workflows.

Answer

Use GlideAggregate to perform the update.

Answer

Use an export set to update records in bulk.

Answer

Use the updateMultiple method on a GlideRecord object.

Question 11

Which TWO of the following are valid ways to reduce the number of database queries when processing multiple records in a script?

Accepted Answer

Use dot-walking to access related table fields.. The valid ways to reduce database queries when processing multiple records are A and C. Dot-walking (A) follows relationships without separate queries. GlideAggregate (C) performs aggregation server-side, reducing round trips. Option E is incorrect because using GlideRecord's get() method with a sys_id still executes a separate database query for each call, so it does not reduce queries. Options B and D increase queries: B uses multiple queries, and D uses getValue() which does not reduce queries since it accesses a field from an already retrieved record.

Answer

Use multiple GlideRecord queries for each record.

Answer

Use getValue() to retrieve field values individually.

Answer

Use GlideRecord's get() method with a sys_id set.

Question 12

When using an Import Set, the developer notices that some records are not being inserted even though no errors appear. The transform map has a condition script. What is the most likely cause?

Accepted Answer

The condition script returns false for those records.. The condition script in the transform map runs for each record. If it returns false, the record is skipped without any error. This explains why some records are not inserted despite no errors. Option A (data source filter) could also filter records, but the question specifically mentions a condition script, making D the most direct cause. Option B (incorrect field mappings) would typically result in mapping errors, not silent failure. Option C (business rule on target table) would usually generate errors or cause a rollback, not silent omission.

Answer

The data source has a filter that excludes those records.

Answer

The field mappings are incorrect for those records.

Answer

A business rule on the target table rejects the records silently.

Question 13

Which TWO are valid data source types for Import Sets in ServiceNow? (Choose two.)

Accepted Answer

JDBC. The correct answers are A and B. REST and JDBC are both valid data source types for Import Sets. LDAP, SNMP, and Syslog are not supported as data source types.

Answer

LDAP

Answer

SNMP

Answer

Syslog

Question 14

An import set is failing because some records have duplicate values in a unique field. The requirement is to skip duplicates and import only new records. Which transform map option should be used?

Accepted Answer

Enable 'Coalesce' on the unique field and set 'Action' to 'Insert' in the transform map.. Coalesce on the unique field allows the transform map to identify existing records by matching the incoming field to a unique field in the target table. Setting the Action to 'Insert' ensures that only new records are imported; if a match is found, the record is skipped (since it already exists). Option A ('Import set update only') is not a standard option in ServiceNow. Option B ('Update existing records') would update duplicates rather than skip them. Option C ('Reject duplicates') is not a typical option in data sources; the correct approach is using coalesce with Insert action.

Answer

Enable 'Import set update only' in the transform map.

Answer

Enable 'Update existing records' in the transform map.

Answer

Enable 'Reject duplicates' in the data source options.

Question 15

A company uses IntegrationHub to connect to an external CRM. The OAuth provider record and REST message are configured. When testing, authentication fails. What is the most likely cause?

Accepted Answer

The OAuth provider profile is not linked to the REST message.. The most likely cause of authentication failure is that the OAuth provider profile is not linked to the REST message. Without this linkage, the authentication configuration is not applied. Option A is incorrect because base64 encoding of the client secret is not a requirement for OAuth. Option C is incorrect because the grant_type parameter is sent in the request body, not in the URL. Option D is incorrect because although POST is the correct HTTP method for token requests, the method itself is not the likely cause of authentication failure.

Answer

The client secret is not base64 encoded.

Answer

The token URL is missing the grant_type parameter.

Answer

The REST message is set to POST instead of GET.
