CSA Exam Dumps - ServiceNow Certified System Administrator Questions and Answers

InServiceNow,User Impersonationallows anadmin or a user with the appropriate roleto temporarily act as another userwithout needing their password. This is mainly used fortesting and visibility, helping administrators and developers verify user permissions, role-based access, and UI experiences.

Testing Permissions & Roles

Ensures thatusers have the correct access rights(e.g., verifying ITIL user permissions for incident management).

Helps testUI Policies, Business Rules, and ACLs (Access Control Rules)by viewing the system from the perspective of different roles.

Debugging & Troubleshooting

Identifies why a usercannot access certain records or modules.

Helps inresolving permission-related issueswithout affecting live users.

Experience Validation

Ensures userssee the correct menus, fields, and optionsbased on their assigned roles.

Useful when developingnew applications, workflows, or Service Catalog items.

Admins and authorized userscan impersonate by clicking on their name in the top-right corner and selectingImpersonate User.

Once impersonated, all actions are logged for security and compliance.

Primary Functions of User Impersonation:How to Use Impersonation:

(A) Testing and visibility – Correct

The primary function ofuser impersonationis totest and verify what different users can see and doin the system.

It helps withdebugging UI, role-based access, ACLs, and workflow execution.

(B) Activate verbose logging – Incorrect

Verbose loggingis used fordetailed debugging and performance monitoring, butimpersonation does not enable logging features.

(C) View custom perspectives – Incorrect

ServiceNow doesnotuse the term "custom perspectives" in the context of impersonation.

Impersonationshows what a specific user sees based on their roles, but it doesnot create custom perspectives.

(D) Unlock Application master list – Incorrect

There isno such featureas an "Application Master List" that requires impersonation to unlock.

Application access is controlled byroles and permissions, not impersonation.

Explanation of Each Option:

Never impersonate a user without permission, especially in production environments.

All impersonation actions are loggedin the system for security and auditing purposes.

Use impersonation in a sub-production (development or test) instancebefore making changes to production.

Admins should use impersonation instead of logging in with test user accountsto maintain security and accountability.

In ServiceNow, every table has a uniqueplatform name(also known as thedatabase nameorsys_id). The table that stores user records in ServiceNow is called"sys_user".

Table Name:sys_user

Purpose:Stores user records, including their roles, group memberships, and personal details.

Location in ServiceNow:You can access this table by navigating to:All → Users and Groups → Users

Key Fields in sys_user Table:

User ID (user_name)– Unique identifier for the user.

Name (name)– Full name of the user.

Email (email)– Email address of the user.

Roles (roles)– Defines user permissions in the system.

Active (active)– Indicates if the user is active in the system.

A. u_users– Incorrect. The prefixu_is typically used forcustom tablescreated by administrators. This is not a default system table.

B. sys_users– Incorrect. The correct name issys_user(singular), notsys_users. ServiceNow follows a singular naming convention for system tables.

C. x_users– Incorrect. The prefixx_is reserved forScoped Applicationscreated within an instance. The User table is a core system table, not a scoped one.

Understanding the sys_user Table:Explanation of Incorrect Answers:References from Certified System Administrator (CSA) Documentation:

TheApplication Navigator (App Navigator) search fieldin ServiceNow allows users to quickly findapplications, modules, and favoritesby typing relevant keywords. It helps in easy navigation by filtering available options as the user types.

Thefour correct answersdescribe what the App Navigator search field can return:

The search field can return bothapplicationsand their respectivemodulesin the left navigation panel.

Example: Searching for "Incident" will return:

Application:"Incident"

Modules:"All", "Open", "Resolved", "Create New"

Modulesare specific functionalities within an application.

Searching by a module name directly will display results that match the keyword.

Example: Searching for "Create New" will return modules like:

"Create New Incident"

"Create New Change Request"

The search field supports findingfull applicationsby their name.

Example: Typing "Change" will display theChange Managementapplication and its related modules.

If a user has marked specific modules or applications asFavorites, they will appear in search results.

This helps users quickly access commonly used features.

1. Names of Applications and Modules (Correct)2. Names of Modules (Correct)3. Names of Applications (Correct)4. Favorites (Correct)

Why the Other Options Are Incorrect:E. History Records (Incorrect)

TheHistory tabin the navigation panel showsrecently accessed records, but it isnot searchable through the App Navigator.

Instead, users can find history under:

History Module(System Settings > History)

Recent History Tabin the left navigation

F. Titles of Dashboard Gauges (Incorrect)

Dashboard Gaugesare visual elements onPerformance Analytics or Reporting Dashboardsand arenot searchablein the App Navigator.

Instead, dashboards and reports are found under:

Self-Service > Dashboards

Performance Analytics > Dashboards

A ServiceNow user wants toquickly access the "All Incidents" module.

They type "incident" into the App Navigator search.

The search results return:

Incident (Application)

All (Module)

Assigned to Me (Module)

Resolved (Module)

Example Use Case:This allows for quick navigation without manually expanding application menus.

TheSystem Dictionaryin ServiceNow stores and maintains themetadataabout tables and fields in the platform. It containsdefinitions for each table and column, including field data types, default values, and attributes.

Storestable and field definitions, including:

Column names

Data types(e.g., String, Integer, Reference)

Attributes(e.g., unique, read-only, required)

Default values

Ensuresdata integrityby defining the structure of database tables.

Used by administrators tomodify or extend existing tables.

Allows the creation ofcustom fieldsin tables.

Key Features of the System Dictionary (sys_dictionaryTable):

Navigate to:System Definition → Dictionary

Search for a table or fieldto view its metadata.

Modify attributes(if needed) to customize table behavior.

How to Access the System Dictionary:

A. The human-readable labels and language settings– Incorrect.

Human-readable labelsare stored in thesys_documentationtable, not the System Dictionary.

C. The information on how tables relate to each other– Incorrect.

Table relationshipsare stored in theSchema Map, not the System Dictionary.

D. The language dictionary used for spell checking– Incorrect.

Spell checking and translationsare managed insystem localization settings, not the System Dictionary.

ServiceNow follows asingle-instance, single-tenant architecture,nota multiple-tenant architecture. This means:

Single-Instance:

Each ServiceNow instance is aunique, independent environmentfor a customer.

All customers have their own dedicated instance with their owncustom configurations, data, workflows, and applications.

ServiceNow instances are hosted in amulti-instance cloud modelrather than a multi-tenant model.

Single-Tenant Model (Multi-Instance Architecture):

Unlikemulti-tenant architectures(where multiple customers share the same application and database), ServiceNow provideseach customer with a separate, isolated instance.

Thisensures data security, performance isolation, and customization flexibility.

Each instance has its owndata storage, configuration, and upgrade schedule, reducing risks associated with shared environments.

Why ServiceNow Uses Multi-Instance Instead of Multi-Tenant:

Security & Data Isolation:Since each customer has an independent instance, there isno risk of data leakagebetween tenants.

Customization & Flexibility:Customers cancustomizetheir instance freely without affecting others.

Performance & Scalability:Each instance can bescaled independently, ensuring optimal performance.

ServiceNow does NOT use a multiple-tenant architecture.

ServiceNow follows a single-instance, single-tenant (multi-instance) model.

Each customer has a dedicated instance with isolated resources and configurations.

A multi-tenant architecturemeans multiple customerssharethe same application/database with logical separation, which is NOT the case in ServiceNow.

ServiceNow instead provides separate instancesfor each customer, meaning it isnota true multi-tenant system.
