InServiceNow, aBreadcrumbis thestring of filter criteriadisplayed at the top of a list when filters are applied. Breadcrumbs help usersnavigate and refine filterswithout having to manually edit conditions.

Navigate to a list view(e.g., Incidents, Requests).

Apply a filter (e.g., "Priority is High" AND "State is New").

Abreadcrumb stringappears, displaying the filter conditions.

Users canclick on different parts of the breadcrumbto adjust or remove filter conditions dynamically.

A. Topic

Topics are used inKnowledge Management and Virtual Agentbut do not represent filter criteria.

B. Choice

A Choice refers todropdown optionsin ServiceNow fields, not filters.

D. Menu

Menus provide navigation options, but they do not display filters.

AnUpdate Setin ServiceNow is a container thatcaptures configuration changes(such as form modifications, business rules, or UI policies) made in an instance. These changes can then bemigrated from a development (Dev) environment to a test or production environment.

Key Features of Update Sets:✔Capturesform modifications, ACLs, scripts, and configurations.

✔Helps inmigratingchanges between instances (Dev → Test → Prod).

✔Ensuresconsistency across environments.

B. Transform maps

Used for mapping data fieldsduring an import, not for migrating configuration changes.

C. System dictionaries

Defines table and field attributesbut does not store configuration changes for migration.

D. Import sets

Used for importing external datainto ServiceNow, not for transferring configuration changes.

InServiceNow, impersonation allows administrators toact as another userto troubleshoot, test permissions, or verify user experiences.

Tolog impersonation eventsin theSystem Log, the system property:

CopyEdit

glide.sys.log_impersonation

must beaddedand set totrue(true).

Key Features ofglide.sys.log_impersonation:Logswho impersonated whomin theSystem Log.

Capturestimestamp, user details, and session activity.

Helps withauditing and security compliance.

Navigate toSystem Definition > System Properties.

Search forglide.sys.log_impersonation.

If it doesn’t exist, create it:

Name:glide.sys.log_impersonation

Type:True/False

Value:true

Save the property and test impersonation.

How to Enable Impersonation Logging:

A. glide.user_setting →Incorrect

Not related to impersonation logging.

Deals withuser preferences and settings.

B. glide.sys.all_impersonation →Incorrect

No such property exists in ServiceNow.

D. glide.impersonation_setting →Incorrect

Incorrect property name; does not exist.

E. glide.sys.admin_login →Incorrect

Logsadmin logins, not impersonation events.

BothUI PoliciesandData Policiesare used to enforce rules on data in ServiceNow, but they work differently in terms ofwhere and howthey apply.

Key Differences Between UI Policies and Data Policies:Feature

UI Policy

Data Policy

Scope

Worksonly on formsin the user interface (UI)

Works onall data entry methods, including forms, imports, and web services

Execution

Runsclient-sidein the browser

Runsserver-sideon the database

Purpose

Dynamicallyshow/hide, make fields mandatory, or read-onlyon forms

Enforcesmandatory and read-only fieldsat thedatabase level

Applies to

Userinteractions on forms

All data sources(Forms, Import Sets, Web Services, API)

Conversion

Can be converted into Data Policies

Cannot be converted into UI Policies

Why "B. Data Policies run regardless of how data is entered into ServiceNow, while UI Policies are used for form interactions" is Correct:Data Policies apply to all data entry methods, ensuring data integrity no matter how the data enters ServiceNow.

UI Policies only apply to the user interface (forms)and dynamically modify field behavior in real-time.

A. Data Policies run only after UI Policies run successfully→UI Policies and Data Policies work independently and do not depend on each other.

C. Data Policies can be converted into UI Policies, but UI Policies cannot be converted into Data Policies→The opposite is true: UI Policies can be converted into Data Policies, but not the other way around.

D. Data Policies run when data is entered through the form, by an Import Set, or by Web Services, while UI Policies are set only by web services→UI Policies arenot related to web services; they only apply to form interactions.

Why Other Options Are Incorrect:

ServiceNow Documentation:UI Policies vs. Data Policies

CSA Exam Guide:CoversUI Policies and Data Policies differencesin form and system-wide data enforcement.

Reference from CSA Documentation:Thus, the correct answer is:

B. Data Policies run regardless of how data is entered into ServiceNow, while UI Policies are used for form interactions

ABusiness Rulein ServiceNow is aserver-side scriptthat executes when records are inserted, updated, deleted, or queried in a specified table. Business Rules allow automation and customization of workflows by defining logic that runs under specific conditions.

Table (B) –Correct

ABusiness Rulemust be associated with aspecific tablewhere it will execute (e.g., Incident, Change, Task).

This determineswhich recordsthe rule applies to.

Script to Run (E) –Correct

A script must be provided when defining advanced logic in a Business Rule.

Business Rules useserver-side JavaScriptto perform various actions, such as setting field values, enforcing validation, or triggering workflows.

Timing (H) –Correct

The execution timing of a Business Rule determineswhenit runs relative to a database transaction.

Business Rules can run:

Before(before record is saved)

After(after record is saved)

Async(after the transaction completes)

Display(when a form loads)

Condition to Evaluate (I) –Correct

Conditions definewhen the Business Rule should executebased on specific criteria.

Example: A Business Rule might runonly when the priority is set to High.

A. UI Action(Incorrect)

UI Actions (buttons, links, context menus) are separate from Business Rules and are used for UI customization.

C. Fields to update(Incorrect)

While Business Rules can update fields,you do not specify "fields to update" as a required setting. Instead, updates are made via scripts within the rule.

D. Who can run(Incorrect)

Business Rulesalways run on the server-sideand do not require user-specific execution settings.

F. Application Scope(Incorrect)

Although Business Rules belong to an application scope, this isautomatically determinedbased on the current application.

G. Update Set(Incorrect)

Business Rules arecaptured in an Update Set, but this is not a configuration setting while creating the rule.

Key Elements to Specify When Creating a Business Rule:Incorrect Options:Official References from Certified System Administrator (CSA) Documentation:

In ServiceNow, when applying filters, theFunnel iconopens the condition builder, allowing users to set criteria for displaying records.

Understanding the requirement:

The user wants to seeIncidents where the state is ClosedORIncidents where the Assignment Group is Network.

The key word here isOR, meaning records satisfyingeithercondition should be displayed.

Steps to apply this filter in ServiceNow:

Click theFunnel iconto open the condition builder.

Define thefirst condition→ SelectState = Closed.

Click theORbutton (since we want records meeting either condition).

Define thesecond condition→ SelectAssignment Group = Network.

PressEnterto apply the filter.

Since the user wantseither condition to be true,ORis the correct logical operator.

PressingEnterafter defining the second conditionexecutes the filter.

A. Define the first condition; click AND button; define second condition; click Run:Incorrect becauseANDwould requireboth conditions to be true simultaneously, which is not what the user wants.

B. Define the first condition; click AND button; define second condition; press enter:Same issue as option A—AND willnarrow the resultsinstead ofexpanding them.

D. Define the first condition; click > icon on breadcrumb, define second condition; click Run:Thebreadcrumb navigationis used to modify filtersafter applying them, not to create them initially.

E. Define the first condition; click > icon on breadcrumb, define second condition; press enter:Same issue as option D—breadcrumb navigation is for modifying, not for initial filter creation.

Why is the Correct Answer "C"?Why Not the Other Options?References from the Certified System Administrator (CSA) Official Documentation:UsingORensures both conditions are considered independently, displaying incidents that are eitherClosedor assigned toNetwork.

InServiceNow,Number Maintenanceis the application used to manage and modify numbering schemes for different tables, including theIncidenttable. Since the default prefix forIncident numbersis"INC", an administrator can modify it to a company-specific prefix (e.g.,"IN") by following these steps:

Navigate to the Number Maintenance Application:

Go toAll → System Definition → Number Maintenance

Search for theIncident table (task.number record for Incident).

Modify the Prefix:

Open the existingIncident numbering record.

Change thePrefixfrom"INC"to"IN".

Ensure theNext Numberfield is correctly set (e.g.,"IN0001001").

Save the Changes:

ClickUpdateto apply the new prefix.

All newly created incidents will now follow the new format (IN0001001).

Existing incidents are NOT affected—only newly created records will reflect the new prefix.

Steps to Change the Incident Number Prefix:Why Option A (Number Maintenance) is Correct?The Number Maintenance application is the correct place to modify prefixes for tables like Incident.

Why Other Options Are Incorrect?B. Create a Business Rule that modifies the prefix before the Insert operation→ Incorrect

Business Rulesdo not control number generation.

Number generation is managed byNumber Maintenanceat the system level.

C. The prefix of an incident cannot be changed because it is a built-in feature→ Incorrect

The prefixCAN be changedusing theNumber Maintenanceapplication.

Only existing records retain their original prefix; new records follow the updated format.

D. Submit a Change Request to ServiceNow Technical Support→ Incorrect

This isnot necessary, asadministratorscan make this change directly throughNumber Maintenance.

ATransform Mapin ServiceNow is a tool used to define relationships betweenfields in an import set tableandfields in a target table. It helps map incoming data to the appropriate fields within the ServiceNow database when importing data from external sources.

Data is loadedinto anImport Set Table.

ATransform Mapis created to define how fields from the import set correspond to fields in the target table.

TheTransformation Processis executed, applying the mapping rules.

The data is stored in theTarget Tablewith any specified transformations applied.

Supportsfield mapping,scripted transformations, andcoalesce fields(for avoiding duplicate records).

Allows fordata cleansing and standardizationduring the transformation process.

Can be reused for multiple data imports.

A. Transform Schema→ No such concept exists in ServiceNow.

B. Schema Map→ Provides a visual representation of table relationships but does not define field mappings for imports.

C. Dictionary Map→ Used for mapping between dictionary definitions, not for transforming import set data.

E. Field Transformer→ Not a ServiceNow tool.

F. Import Designer→ No such module in ServiceNow.
