Certified System Administrator CSA Book

In ServiceNow,Pluginsare used to activate additional applications or functionalities within a development instance. A plugin is apackage of features, configurations, and applicationsthat extends the platform’s capabilities.

Plugins introduce new capabilities– They allow you to enable or disable specific functionalities, such as ITSM, CMDB, HR Service Delivery, and Performance Analytics.

Plugins can be installed or activatedfrom theSystem Definition > Pluginsmodule.

Some plugins are available by default, while others require activation by an administrator or ServiceNow support.

Plugins can depend on other plugins, meaning some functionality requires multiple plugins to be activated.

A. App Package:No such term in ServiceNow. Applications in ServiceNow are delivered viaPlugins or App Engine Studio, not "App Package."

B. Updated Pack:Not a ServiceNow term. ServiceNow updates are delivered aspatches or application updates, not an "Updated Pack."

C. Patch:Apatchis a minor update or bug fix released by ServiceNow but does not introduce new functionality.

E. App Updated Set:Update Setstrack changes in a development instance but are used formigrating configurationsbetween instances, not for activating functionality.

Managing and Activating Plugins in ServiceNow(Admin Guide)

Why is the Correct Answer "Plugin"?Why Not the Other Options?References from the Certified System Administrator (CSA) Official Documentation:

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.

TheFlow Designermodule in ServiceNow is used to create and manageautomationsthat involve business logic such asapprovals, tasks, notifications, and integrations. It provides ano-code/low-codeenvironment where users can define automated workflows without needing to write scripts.

Automates Processes– Handles approvals, notifications, and task assignments.

No-Code Interface– Users can build workflows using adrag-and-dropinterface.

Replaces Legacy Workflows– Flow Designer is themodernalternative to Workflow Editor.

Integrates with Spokes– Can connect to other systems usingIntegration Hub.

Triggers– Define when a flow starts (e.g., record changes, schedules, API calls).

Actions– Define what happens (e.g., create a task, send an email, update a record).

Conditions– Add logic to control execution paths.

B. Process Automation > Flow Administration→ Used formanaging existing flows, not creating new ones.

C. Process Automation > Workflow Editor→ This is thelegacyworkflow automation tool, replaced by Flow Designer.

D. Process Automation > Process Flow→ No such module exists in ServiceNow.

E. Process Automation > Active Flows→ Displaysalready running flows, but does not allow new flow creation.

InServiceNow Reporting,Function Fieldsare used toperform calculations, manipulate text, and transform datain a report. These fields allow users to applyarithmetic operations, coalescing, concatenation, and length calculationson existing data.

Arithmetic Operations– Performaddition, subtraction, multiplication, and divisionon numeric fields.

Coalesce– Combine multiple fields into one (useful for handling NULL values).

Concatenation– Join multiple string fields together (e.g., combining first and last names).

Length Calculation– Measure the length of a text field (e.g., checking character count in a description field).

Function fields aredesigned specifically for calculations and data transformationsin reports.

They allowadvanced data processing without requiring scripting.

A. Sourcing Fields→Incorrect

"Sourcing Fields" isnot a valid termin ServiceNow reporting.

C. Computational Fields→Incorrect

While this term sounds relevant,ServiceNow does not use "Computational Fields" in reporting.

D. Calculation Fields→Incorrect

"Calculation Fields" is not an official ServiceNow reporting term.

Function fields handle calculations, not a separate category called "Calculation Fields."
