SNOW-CAD Practice Test 12 — 15 Questions

Question 1

As a best practice, which method should be used to schedule recurring data imports from external sources?

Accepted Answer

Configure a scheduled job to use the Import Set API or transform. Scheduled jobs are the native ServiceNow mechanism for running recurring, unattended work such as pulling data from external sources on a defined interval. Pairing a scheduled job with the Import Set API (or a transform) lets the job POST data into an import set table and then run the transform map to coerce it into target tables. This is the documented best practice for recurring imports because it is repeatable, auditable, and does not require manual intervention.

Answer

Deploy an update set for each import

Answer

Use a Flow Designer flow with an HTTP trigger

Answer

Create a business rule that triggers on a condition

Question 2

Which THREE best practices should a developer follow when designing a service portal widget? (Choose three.)

Accepted Answer

Define widget options for configuration. Option A is correct because defining widget options allows the widget to be configured and reused across different portal pages without modifying its code, which is a core Service Portal best practice. Option C is correct because server-side scripts (the widget's Server Script) should be used to fetch data securely and efficiently, keeping sensitive queries and GlideRecord operations off the client. Option E is correct because the Client Script field should be used sparingly and only for UI interactions such as DOM manipulation or client-side event handling, since heavy logic there hurts performance and maintainability. Option B is incorrect because the server-side script is exactly where data retrieval and business logic belong, so avoiding it entirely is not a best practice. Option D is incorrect because relying exclusively on client-side scripts for data retrieval is insecure and inefficient, as it exposes logic and bypasses server-side controls.

Answer

Avoid using the widget's server-side script for any logic

Answer

Use client-side scripts exclusively for data retrieval

Question 3

A developer is creating a Scheduled Job in Studio that needs to run every hour. Which type of trigger should be selected?

Accepted Answer

Interval. (Interval) is correct because an Interval trigger allows you to specify a repeat interval, such as every 60 minutes, which meets the requirement to run every hour. Option A (Date) runs once at a specific date/time. Option B (Run once) runs a single time. Option D (Daily) runs once per day.

Answer

Date

Answer

Run once

Answer

Daily

Question 4

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 5

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.. Option A is correct because dot-walking lets a single GlideRecord query traverse reference fields to pull related table values (e.g., current.caller_id.email) without issuing a separate query per related record, thereby reducing the total number of database queries. Option C is correct because GlideAggregate performs aggregation (COUNT, SUM, AVG, MIN, MAX, GROUP BY) directly in the database, replacing the pattern of iterating over many records and querying repeatedly, which drastically cuts query volume. Option B is wrong because issuing multiple GlideRecord queries for each record multiplies database round-trips rather than reducing them. Option D is wrong because getValue() merely retrieves a field value from an already-loaded record and does not itself reduce the number of queries. Option E is wrong because GlideRecord.get() with a sys_id executes a single-record lookup and, when called per record, increases rather than decreases query count.

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 6

A developer wants to use ServiceNow Studio to create a client script that runs when a form loads and sets a field value based on the current user's department. Which type of client script should be used?

Accepted Answer

onLoad client script. An onLoad client script runs automatically when a form is opened, making it the correct choice for setting a field value based on the current user's department at the time the form loads. This script type executes in the browser after the form data is retrieved but before the user interacts with the form, allowing immediate field population.

Answer

onChange client script

Answer

onSubmit client script

Answer

onCellEdit client script

Question 7

A large enterprise uses ServiceNow as its ITSM platform. They have an existing LDAP directory that contains user accounts and group memberships. They want to synchronize user accounts from LDAP into the ServiceNow user table (sys_user) and automatically assign roles based on group membership. The LDAP server supports both user and group synchronization. The administrator has configured an LDAP server record and a user import transform map. After running the LDAP user import, all users are created but none have roles assigned. The LDAP group import transform map is configured to load groups into the sys_user_group table and members into the member list. The administrator verified that the LDAP group import runs successfully and populates groups with members. However, the expected roles are still missing. What is the most likely cause and solution?

Accepted Answer

The administrator did not configure role-to-group mapping in the LDAP server record. Solution: define the mapping in the 'Role' related list on the LDAP server configuration.. In ServiceNow, role assignment via LDAP group synchronization requires explicit role-to-group mapping on the LDAP server record. Even when groups and members are imported correctly, roles are not automatically assigned unless the administrator defines which LDAP group corresponds to which ServiceNow role in the 'Role' related list on the LDAP server configuration. Without this mapping, the system has no instruction to link group membership to role inheritance.

Answer

The LDAP group import is not correctly associating users to groups. Solution: check the member attribute mapping in the group import transform map.

Answer

The LDAP user import is not populating the 'group' field on the user record. Solution: add a field mapping to copy the group DN.

Answer

The LDAP user import transform map does not have a coalesce field set, causing duplicate users. Solution: set coalesce on the user ID field.

Question 8

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

Accepted Answer

Insert. Business rules in ServiceNow can be triggered by database operations such as Insert and Update. These are the core 'when to run' conditions that fire the rule before or after a record is created or modified in the database. Options B and D are correct because they directly correspond to these fundamental database operations.

Answer

Form load

Answer

Timer event

Answer

Inbound email receipt

Question 9

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

Accepted Answer

GlideAggregate can be used to perform SQL-like GROUP BY operations.. GlideAggregate extends GlideRecord and allows performing SQL-like GROUP BY operations on database queries, enabling aggregation of data such as sums, counts, averages, etc. Option C is correct because GlideAggregate can be instantiated and used within a business rule to compute aggregated values from the database, which is a common pattern for server-side calculations.

Answer

GlideAggregate allows adding non-aggregated fields to the result set using addField().

Answer

GlideAggregate automatically orders the results by the aggregated field.

Answer

GlideAggregate can only be used in client scripts.

Question 10

A developer needs to create a new table in ServiceNow to track project milestones. The table should have a reference field to the Project table and a date field for the milestone date. Which data type should be used for the reference field?

Accepted Answer

Reference. In ServiceNow, a reference field is specifically designed to create a relationship between two tables by storing the sys_id of the referenced record. This allows the developer to link a project milestone record to a specific project record in the Project table, enabling dot-walking and data integrity through referential integrity constraints.

Answer

GlideRecord

Answer

Integer

Answer

String

Question 11

A developer is creating a custom application in ServiceNow Studio and wants to ensure that the application can be easily installed in other instances without conflicts. Which approach should the developer follow?

Accepted Answer

Create the application with a unique scope prefix in Studio and export as a scoped application.. Creating an application with a unique scope prefix in ServiceNow Studio ensures that all application artifacts (tables, scripts, UI elements) are isolated within that scope, preventing naming conflicts with other applications. Exporting as a scoped application allows the application to be installed in other instances via the ServiceNow Store or manual import, preserving its scope isolation and dependencies.

Answer

Develop the application in global scope and manually copy components to target instances.

Answer

Use the 'Application' module in the navigator to create a new application without scope.

Answer

Create the application in the global scope and use update sets for distribution.

Question 12

Which table property can be set to limit the creation of new records to certain roles?

Accepted Answer

Create access. The 'Create access' property on a table specifies which roles are allowed to create new records. Option A is incorrect: 'Allow attachment' controls whether users can add attachments to records, not creation. Option B is incorrect: 'Abbreviated table' sets a short name or prefix for the table, not access control. Option D is incorrect: 'Effective access' is a read-only property showing the user's current access rights, not a setting to restrict creation.

Answer

Allow attachment

Answer

Abbreviated table

Answer

Effective access

Question 13

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 14

A table 'u_inventory' has a reference field to the 'Location' table. The developer wants the reference field to display the location name instead of the sys_id in the form. Which attribute should be configured?

Accepted Answer

Reference display field. 'Reference display field'. This attribute on the dictionary entry of the reference field specifies which field from the referenced table (Location) to display in the form. Option A is wrong because 'Default value' sets a default value for the field, not the display. Option B is wrong because 'Reference qualifier' filters which records are available in the reference field. Option D is wrong because the 'Display' field on the Location table controls the default display of that table's records globally, but for a specific reference field, the 'Reference display field' overrides it.

Answer

Default value

Answer

Reference qualifier

Answer

Display field in the Location table

Question 15

A company is integrating ServiceNow with an external ticketing system using a custom REST API. The integration should push updates from ServiceNow to the external system when a change request is approved. Which ServiceNow feature is best suited for this?

Accepted Answer

Business Rule with outbound REST call. A Business Rule with an outbound REST call is the best fit because it triggers automatically on the 'approved' state change of a change request and can execute a synchronous or asynchronous REST API call to the external ticketing system. This allows real-time push of updates without manual intervention or polling, directly meeting the requirement to push updates upon approval.

Answer

REST API Explorer

Answer

Access Control List (ACL)

Answer

Scheduled Job
