SNOW-CAD Practice Test 18 — 15 Questions

Question 1

A scoped application includes a script include that is intended to be used by a business rule in the global scope. The script include is marked as 'Client callable: false' and 'Accessible from: This application only'. The business rule cannot call the script include. Which change fixes this?

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

Accepted Answer

Change 'Accessible from' to 'All application scopes'. The business rule in the global scope cannot access a script include restricted to 'This application only'. Changing 'Accessible from' to 'All application scopes' allows the global-scope business rule to invoke the script include, as cross-scope access is controlled by this property. The 'Client callable' setting is irrelevant for server-side business rules.

Answer

Set the script include name to start with 'global_'

Answer

Move the script include to the global scope

Answer

Set 'Client callable' to true

Question 2

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 3

A large enterprise uses ServiceNow for IT service management. The instance has a custom table 'u_asset_tracker' with over 2 million records. The table is referenced by multiple other tables. Recently, users have reported that when they open a record in the 'u_asset_tracker' table, the form takes 15-20 seconds to load. Additionally, reports that query this table often time out. The instance is running on a mid-range server with 8GB RAM. The admin suspects database performance issues. Upon reviewing the sys_properties, the admin finds that 'glide.ui.auto_clear_filters' is set to false. Also, there are several business rules on the table that run on 'before' query and 'after' query. A script include that transforms data from 'u_asset_tracker' to another table is running frequently. The admin needs to improve performance. Which course of action should the admin take first?

Accepted Answer

Review and disable unnecessary 'before query' and 'after query' business rules on the table.. Disabling unnecessary 'before query' and 'after query' business rules reduces the overhead on every query, which can significantly improve load times for large tables like 'u_asset_tracker'. Option A is incorrect because replacing GlideRecord with GlideAggregate is not a general performance fix; GlideAggregate is designed for aggregate calculations (e.g., count, sum) and cannot replace standard record retrieval. Option B is incorrect because disabling the script include may break data transformation functionality and is not a targeted performance improvement. Option D is incorrect because increasing server RAM may help in some cases, but it does not address the root cause of excessive business rule execution on queries.

Answer

Replace all GlideRecord queries with GlideAggregate for reports.

Answer

Disable the script include that transforms data to reduce load.

Answer

Increase the server RAM to 16GB to handle the load.

Question 4

A company is redesigning a service catalog item that has multiple variables. Some variables should only appear when a specific value is selected in a previous variable, and some fields must be mandatory based on the selected options. The development team is debating whether to use UI policies or client scripts for this logic. What is the best practice for implementing such dynamic behavior in a ServiceNow catalog item?

Accepted Answer

Use UI policies for visibility and mandatory conditions, and use client scripts only for advanced logic that UI policies cannot handle.. Best practice in ServiceNow is to use UI policies for visibility and mandatory conditions because they are declarative, easier to maintain, and execute on the client side without scripting. Client scripts should be reserved for advanced logic that UI policies cannot handle, such as complex calculations or interactions with other variables. This approach minimizes custom code and improves performance.

Answer

Always use client scripts for visibility and mandatory conditions to handle complex scenarios.

Answer

Configure Access Control Lists (ACLs) to restrict field access based on user roles and variable values.

Answer

Use a workflow to control field visibility and mandatory settings based on variable values.

Question 5

A developer implemented an ACL to restrict read access on the 'incident' table. The condition script checks if the user is a member of the 'incident_manager' group. However, users who are not in the group are still able to see incidents. What is the most likely reason?

Accepted Answer

There is another ACL with a lower order that grants read access to all users, and the evaluation never reaches the scripted ACL.. ACLs in ServiceNow are evaluated in order of their 'Order' field (lower numbers first). If a lower-order ACL grants read access to all users, the evaluation stops at that ACL and never reaches the scripted ACL that restricts access to the 'incident_manager' group. This is the most common reason for an ACL appearing to not work — a broader, higher-priority ACL is allowing access before the restrictive one is evaluated.

Answer

The ACL is cached and users need to log out and back in for changes to take effect.

Answer

The condition script returns 'true' for users in the group but does not return 'false' for others, so the ACL defaults to 'no decision' and access is allowed.

Answer

The ACL is set to 'Inactive' so it does not apply, leaving access open.

Question 6

A Script Include is defined as 'Scoped' and has 'Accessible from' set to 'All applications'. It contains a function that uses 'gs.getUser()'. When the Script Include is called from a Business Rule in a different application scope, what is the result?

Accepted Answer

The function runs successfully and gs.getUser() returns the current user from the caller's session.. A Script Include defined as 'Scoped' with 'Accessible from' set to 'All applications' is explicitly made available to other application scopes. When called from a Business Rule in a different scope, the function executes in the context of the caller's session, so `gs.getUser()` returns the current user from the caller's session, not from the Script Include's own scope. This behavior is governed by the scoping rules that allow cross-application access when the property is set accordingly.

Answer

An error occurs because scoped Script Includes cannot be called from other applications.

Answer

The function runs but gs.getUser() returns the user from the Script Include's application scope, not the caller.

Answer

The function runs but returns null because gs is not available in scoped applications.

Question 7

A ServiceNow instance needs to synchronize data with an external SQL database nightly. Which integration method is most appropriate?

Accepted Answer

Use a MID Server with a JDBC data source.. A MID Server with a JDBC data source is the most appropriate method for nightly batch synchronization with an external SQL database because JDBC provides a direct, efficient, and secure database-level connection without requiring the external database to expose a web service or API. The MID Server acts as a secure proxy, allowing the ServiceNow instance to execute SQL queries against the external database over a persistent, encrypted connection, which is ideal for scheduled bulk data transfers.

Answer

Use a REST API exposed by the external database.

Answer

Use a SOAP web service with a MID Server.

Answer

Use an email-based integration to send CSV files.

Question 8

A company has a requirement that the 'state' field of an incident cannot be changed from 'In Progress' to 'Resolved' if the 'category' field is empty. This validation must be enforced server-side to prevent data integrity issues. Which implementation should be used?

Accepted Answer

Create a 'before' Business Rule that checks if the state is changing to 'Resolved' and if category is empty, aborts the update with an error message.. A 'before' Business Rule executes on the server before the database operation and can call current.setAbortAction(true) to prevent the update when the condition is met. This enforces the validation server-side regardless of client, API, or import path, which is exactly what the requirement demands.

Answer

Make the 'category' field mandatory using a Data Policy.

Answer

Configure an ACL on the 'state' field to deny write access when category is empty.

Answer

Create a Client Script on 'state' change that checks if category is empty and shows an error message.

Question 9

An import set loads data from a CSV file into the staging table successfully, but the transform map does not run. The import set rows show status 'loaded'. What is the most likely cause?

Accepted Answer

The transform map is set to inactive. The transform map is set to inactive, which prevents it from running. Option A is incorrect because the import set table is not empty; rows have been loaded. Option C is incorrect because incomplete field mapping would cause transform errors but not prevent the map from running. Option D is incorrect because a misspelled target table name would likely cause a different issue, such as rows not being created, but the map would still attempt to run.

Answer

The import set table is empty

Answer

The field mapping between source and target fields is incomplete

Answer

The transform map's target table name is misspelled

Question 10

Which TWO are best practices for designing forms in ServiceNow to enhance user experience and maintainability?

Accepted Answer

Leverage related lists to display one-to-many relationships on a form.. Option A is correct because related lists are the standard ServiceNow mechanism for presenting one-to-many relationships (e.g., a user's incidents or an incident's tasks) directly on a form, letting users view and act on child records without leaving the parent record and improving the overall UX. Option D is correct because organizing fields into sections (and columns) groups logically related data, making forms easier to scan, navigate, and maintain as fields are added or reorganized. Option B is not a best practice because 'Use Default Form' is a fallback behavior, not a consistency guarantee; proper form design relies on explicit form layouts, views, and UI policies rather than forcing the default form. Option C is wrong because different record types and roles typically require distinct form views and layouts; a single layout for all record types reduces usability and maintainability. Option E is wrong because reference fields are a core, supported ServiceNow field type and are not inherently a performance problem when used appropriately.

Answer

Always enable the 'Use Default Form' checkbox to ensure consistency.

Answer

Use a single form layout for all record types to reduce complexity.

Answer

Avoid using reference fields on forms as they slow down performance.

Question 11

An organization uses a scheduled data import to load incident data from an external system into ServiceNow. The import set runs successfully, but the transform map sometimes fails to update certain records because the unique key field (sys_id) from the source does not match the sys_id in ServiceNow due to a different format. The team wants to update existing records based on a custom 'external_id' field in the incident table, which is guaranteed to be unique and correctly populated from the source. The target table already has a unique index on 'external_id'. Which configuration should the developer implement to achieve reliable updates?

Accepted Answer

Create a new transform map with coalesce on the 'external_id' field and map the source field to incident.external_id.. By creating a new transform map with coalesce on the 'external_id' field, the system will use the 'external_id' value from the source to match existing records in the incident table. Since a unique index exists on 'external_id', this ensures reliable updates. Option A is incorrect because a database view does not affect import matching logic. Option B is wrong because coalesce on 'sys_id' would fail due to format differences. Option D does not address the matching issue—increasing frequency does not improve record matching.

Answer

Use a database view to join the import set and incident table on the external_id field.

Answer

Modify the existing transform map to use 'update' action and set coalesce on the sys_id field.

Answer

Increase the scheduled import frequency to overwrite the records.

Question 12

Which THREE factors should be considered when deciding between using a REST API integration and an Import Set for data ingestion?

Accepted Answer

Real-time vs batch processing requirement. Option A is correct because REST API integrations are typically used for real-time, event-driven data exchange, while Import Sets are designed for scheduled or batch loads, so the latency requirement directly drives the choice. Option B is correct because Import Sets are optimized for high-volume bulk ingestion through staging tables and transform maps, whereas REST APIs are better suited to smaller, transactional payloads. Option D is correct because Import Sets provide robust transformation capabilities via transform maps, coalesce fields, and onBefore/onAfter scripts, so complex transformation needs often favor Import Sets over direct REST writes. Option C does not belong because authentication and authorization are required for any integration method, so they are not a differentiating factor between REST and Import Sets. Option E does not belong because OAuth 2.0 is just one authentication mechanism that can be used with REST APIs and is not a decision factor unique to choosing between REST and Import Sets.

Answer

Need for authentication and authorization

Answer

Support for OAuth 2.0

Question 13

Which TWO accessibility considerations are essential when designing for Service Portal? (Choose two.)

Accepted Answer

Proper heading structure. Option D, proper heading structure, is essential because screen readers and other assistive technologies rely on semantic heading levels (H1–H6) to build a navigable document outline, letting users jump between sections and understand page hierarchy on the Service Portal. Option E, keyboard navigation support, is essential because many users cannot use a mouse, so all interactive elements—links, buttons, forms, and widgets—must be reachable and operable via Tab, Shift+Tab, Enter, and Space, with a visible focus indicator, in line with WCAG 2.1 success criteria. By contrast, Option A (use of color alone) is wrong because conveying information through color only fails WCAG 1.4.1 and excludes color-blind users; Option B (complex data tables without headers) is wrong because tables need programmatically associated <th> headers and scope/caption attributes for screen-reader comprehension; and Option C (auto-play videos) is wrong because autoplaying media violates WCAG 1.4.2, distracts users, and lacks user control over playback.

Answer

Use of color alone for important information

Answer

Complex data tables without headers

Answer

Auto-play videos

Question 14

A developer is designing a solution to allow users to request access to specific applications through a Service Catalog. Each application can be requested by multiple users, and each user can request multiple applications. The request must capture the user's business justification and the date needed. The developer needs to model the data. Which database schema design best adheres to ServiceNow best practices?

Accepted Answer

Create a custom table 'u_application_request' with fields: user (reference to sys_user), application (reference to custom application table), justification (string), date_needed (date). It creates a dedicated 'u_application_request' table with reference fields to both sys_user and the custom application table, plus justification and date_needed fields. This models the many-to-many relationship properly with additional attributes, adhering to ServiceNow best practices of using reference fields for relationships and avoiding unstructured data storage.

Answer

Add a string field on the Application table that stores a comma-separated list of user sys_ids

Answer

Add a multi-reference field on the User table that lists all requested applications

Answer

Create one table for all requests with a reference to both user and application, but store justification and date needed separately in a different table

Question 15

Which THREE considerations are important when designing a scoped application for a customer?

Accepted Answer

Avoid modifying global tables directly.. When designing a scoped application in ServiceNow, it is crucial to avoid modifying global tables directly (B) to prevent unintended side effects and maintain upgradeability. The application name must be uniquely scoped (C) to prevent conflicts with other applications. Including only necessary features (E) reduces complexity and improves performance. Option A is incorrect because minimizing update sets is not a design consideration; update sets are for deployment management. Option D is incorrect because using global Business Rules contradicts the purpose of scoping and can cause cross-scope issues.

Answer

Minimize number of update sets.

Answer

Use global Business Rules for performance.
