InServiceNow, theTask [task]table is acore tablethat provides aset of standard fieldsused by multiple tables that extend it, including:

Incident [incident]

Problem [problem]

Change Request [change_request]

Service Request [sc_request]

These tablesinherit fieldsfrom theTasktable, ensuring consistency inassignments, state management, and workflows.

Standard Fields:

Assigned To

Assignment Group

Priority

State

Created By / Updated By

Short Description / Description

Extensibility:

TheIncident, Problem, and Change tablesallextendthe Task table, inheriting its fields.

Developers canadd additional fieldswhile keeping core task properties intact.

TheTask table is the primary tablefor work-related records in ServiceNow.

Itstandardizes fieldsacross multiple ITSM modules.

B. Assignment [assignment]→Incorrect

There isno standard "Assignment" tablein ServiceNow.

Assignments are managed through theTask tablevia theAssigned To and Assignment Group fields.

C. Service [service]→Incorrect

There isno generic "Service" tablethat acts as a core table for ITSM processes.

Service-related items are stored in different tables, such ascmdb_ci_service(for service records).

D. Workflow [workflow]→Incorrect

TheWorkflow tableis used for managing automated workflows anddoes not store task-related records.

References from Certified System Administrator (CSA) Documentation:This confirms thatthe Task table is the core table that extends to Incident, Problem, and other related tables.

In ServiceNow,Business Rulesare server-side scripts that executeat specific timesrelative to database operations. The"When" settingdetermineswhenthe Business Rule runs in relation to a record action (Insert, Update, Delete, Query).

Why is Option A Correct?Before

Executesbeforea record is saved to the database.

Used tovalidate data, modify values, or prevent an action(e.g., stopping an invalid update).

After

Executesaftera record is inserted, updated, or deleted.

Commonly used fortriggering notificationsor creating related records.

Async (Asynchronous)

Runsaftera database operation but executes inthe background.

Ideal forlong-running or performance-heavy tasks(e.g., integrating with external systems).

Display

Executesbefore a form loads, allowing modifications to fieldsbefore they are displayedto the user.

Typically used forpre-filling form fieldsbased on user roles or conditions.

Why Are the Other Options Incorrect?B. Prior to, Synchronous, on Update

"Prior to"is not a valid Business Rule execution timing.

"Synchronous"is a general term but isnot a specific execution timing optionin Business Rules.

"on Update"is a database operation,not an execution timing.

C. Insert, Update, Delete, Query

These aredatabase operationsthat trigger Business Rules,not execution timings.

Execution timing determineswhen(before, after, etc.), while these determinewhat triggers it.

D. Before, Synchronous, Scheduled Job, View

"Synchronous"is not a Business Rule timing option.

"Scheduled Job"refers toScheduled Jobs(not Business Rules).

"View"is a UI-related concept,not a Business Rule execution timing.

Virtual Agentis ServiceNow’sAI-powered chatbotthat provides assistance via amessaging interface. It helps users obtain information, make decisions, and complete common tasks without human intervention.

Conversational Interface→ Users interact through chat to get information and perform tasks.

Automated Responses→ Uses predefinedtopicsandnatural language understanding (NLU)to provide relevant answers.

Integration with ServiceNow Applications→ Can create incidents, reset passwords, check order statuses, etc.

Available on Multiple Channels→ Works with Microsoft Teams, Slack, and the ServiceNow portal.

A. Agent Workspace→ A unified interface for agents to manage cases, not an AI chatbot.

B. Chat bot→ A generic term; Virtual Agent is the official chatbot in ServiceNow.

D. Knowledge Chat→ No such feature exists; however, Virtual Agent can integrate with the Knowledge Base.

E. Now Support→ ServiceNow’s customer support portal, not an AI-driven assistant.

In ServiceNow, every record in a table has a unique 32-character identifier calledsys_id. This ID uniquely identifies a record and is stored in thesys_id fieldfor every table.

sys_id is a globally unique identifierassigned to every record in ServiceNow.

It is a 32-character hexadecimal string, ensuring uniqueness across instances.

It remains constant for a record, even if other fields in the record are modified.

sys_id is used in API calls, reference fields, and update setsto track records across environments.

A. sn_rec_id:No such field in ServiceNow.

B. rec_id:Not a valid field in ServiceNow.

C. u_id:Not a standard ServiceNow field. Custom fields may use "u_" prefix butu_id is not a system field.

E. sn_gu_id:No such field in ServiceNow.

F. sn_sys_id:No such standard field in ServiceNow.

G. id:Generic term, but not a standard field in ServiceNow.
