ServiceNow Updated CSA Exam Questions and Answers by georgi

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.

sys_id Best Practices for Data Management

Why is the Correct Answer "sys_id"?Why Not the Other Options?References from the Certified System Administrator (CSA) Official Documentation:Thesys_idis crucial for tracking and managing records efficiently in ServiceNow and plays a key role in integrations, workflows, and automation.

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.

In ServiceNow, asys_idis aunique 32-character identifier(UUID - Universally Unique Identifier) that is automatically assigned to every record in the system.

It isa unique 32-character alphanumeric string(e.g.,5137153cc611227c000bbd1bd8cd2005).

Every record in every table in ServiceNow has asys_idfield.

Thesys_id remains the same across instances if the record is transferred via an Update Set.

It helpsuniquely identifyrecords and is used in scripting, APIs, and database relationships.

In theIncident [incident]table, an incident record might have:

Number:INC0012345

sys_id:9d72f6141b122200d37a85e15b2d6fe6

Key Characteristics of sys_id:Example:

Thesys_id is always 32 characters long.

It is acritical part of the ServiceNow database structure.

Used forrelationships, APIs, scripting, and querying records.

Why "A. Unique 32-character identifier that is assigned to every record" is Correct?

B. A client-side Business Rule – Incorrect

Business Rulesdo not generate sys_ids; they control logic execution.

C. A server-side Business Rule – Incorrect

Business Rules are used for automation, but sys_id is a system-generated field.

D. Unique 64-character identifier that is assigned to every record – Incorrect

The correct length of sys_id is32 characters, not 64.

In ServiceNow Flow Designer, anApplication-based triggeris used to initiate a flow based on events from a specific application. Before using an application-based trigger, you must ensure that the necessaryapplication spokeand any requiredplug-insare activated.

Application Spokes:

Spokes are pre-built integration modules that allow Flow Designer to interact with different applications within ServiceNow.

Each application that provides triggers typically has its own spoke.

Plug-ins:

Some application spokes rely on additional plug-ins for full functionality.

These plug-ins must be enabled before the application-based triggers can be used.

A. Activate application trigger spoke→ Incorrect

There is no generic "Application Trigger Spoke." Instead, each application has its own spoke that must be enabled.

B. Activate trigger security rules→ Incorrect

Security rules govern access to triggers, but they do not enable the functionality of application-based triggers.

D. Assign Application trigger role [sn_app_trigger_write] to SME→ Incorrect

Roles likesn_app_trigger_writemay provide permissions but do not activate the trigger itself.

E. Activate application plugins only→ Incorrect

While plug-ins may be necessary, you also need to activate the corresponding spoke.
