ServiceNow Updated CSA Exam Questions and Answers by anais

In ServiceNow, tables are structured in a hierarchical format where some tables can extend others, inheriting fields and properties. However, there are specific tables that do not extend any other table but can be extended—these are known as Base Tables.

Base Tables:

A Base Table is a table that does not extend another table but can be extended by other tables.

It serves as a foundation for creating new tables.

Example:

Task Table (task) – The Incident, Problem, and Change tables extend from the Task table.

Configuration Item Table (cmdb_ci) – Used as a base for various CI types.

Core Tables:

Core Tables are the standard tables provided by ServiceNow.

They can be base tables or extended tables depending on their role.

Example:

Task (task) and User (sys_user) are core tables, but only some core tables are base tables.

Extended Tables:

Extended Tables are tables that inherit fields and functionality from a parent table.

Example:

Incident (incident) extends from Task (task).

Custom Tables:

Custom Tables are tables that developers create for specific business needs.

They may or may not extend another table depending on their design.

Understanding Table Types in ServiceNow

Why Answer "A" is Correct:✔️ "Base Tables" are tables that may be extended by other tables but do not extend another table.

These tables do not inherit fields from any other table.

They provide the foundation for extensions, making them the top-level tables in ServiceNow’s data hierarchy.

Example: The Task table is a base table because it does not extend another table but serves as the foundation for many other tables (e.g., Incident, Problem, Change).

Why the Other Answers Are Incorrect:❌ B. "Core Tables"

Incorrect because Core Tables are standard ServiceNow tables, but they can be either base or extended tables.

Not all core tables follow the definition of a base table.

❌ C. "Extended Tables"

Incorrect because extended tables inherit fields from parent tables, meaning they do extend another table.

Example: The Incident table extends from the Task table, making it an extended table.

❌ D. "Custom Tables"

Incorrect because Custom Tables can be either base or extended tables depending on how they are created.

If a developer chooses to extend an existing table, then it is not a base table.

ServiceNow Data Model Overview (Base Tables & Extended Tables)

References from the Certified System Administrator (CSA) Documentation:

In ServiceNow, the Service Catalog is a centralized portal where users can request IT services, hardware, software, and other business-related items. Within the Service Catalog, the fundamental components are known as Service Catalog Items.

Definition of Service Catalog Items:

A Service Catalog Item represents a specific service, product, or action that a user can request from the Service Catalog.

It is the core component that defines what users can request.

Examples include:

Requesting a new laptop

Submitting an access request

Ordering a software installation

Why They Are the "Building Blocks" of the Service Catalog:

All Service Catalog requests are based on catalog items—without them, the catalog has no offerings.

Each item has associated workflows, approvals, and fulfillment processes that define how the request is handled.

They form the foundation of the Service Catalog because every service request must be tied to an item.

Understanding Service Catalog Items

Why Answer "B" is Correct:✔️ "They are the building blocks."

Service Catalog Items serve as the fundamental components of the catalog.

They define what services and products are available for request.

Without catalog items, the Service Catalog would not function as intended.

Why the Other Answers Are Incorrect:❌ A. "They run behind the scenes."

Incorrect because Service Catalog Items are visible to users in the Service Catalog portal.

While workflows and fulfillment processes may operate in the background, the items themselves are not hidden.

❌ C. "They are optional."

Incorrect because Service Catalog Items are mandatory for a functioning Service Catalog.

The catalog is useless without catalog items, making them essential, not optional.

❌ D. "They provide options."

Incorrect because while Service Catalog Items can have variables (such as dropdown selections or checkboxes), their primary role is not just to provide options but to define the services available.

ServiceNow Tables & Data Model (sc_catalog, sc_cat_item, sc_request, sc_task)

References from the Certified System Administrator (CSA) Documentation:

A Related List in ServiceNow is used to display records from other tables that are related to the current record. It helps users view and manage associated records without navigating away from the main record they are working on.

Related Lists appear at the bottom of a form view.

They display records from tables that have a relationship (via reference fields, many-to-many relationships, or database joins) with the current table.

Users can add, remove, or modify related records directly from the Related List, depending on their permissions.

Key Features of Related Lists:Why "D. To present related records" is the correct answer?Related Lists show records from another table that have a relationship with the current record. For example:

An Incident record may have a Related List showing all Tasks associated with it.

A User record may have a Related List displaying Group Memberships.

A Change Request record may have a Related List displaying all related CI (Configuration Items).

Option A: "To create a one-to-many relationship" – Incorrect. While Related Lists often display one-to-many relationships, they do not create them. Relationships are defined through reference fields, many-to-many tables, or database joins.

Option B: "To dot-walk to a core table" – Incorrect. Dot-walking allows users to access related fields from referenced records, but it is not the purpose of a Related List.

Option C: "To present related fields" – Incorrect. Related Lists display related records, not just individual fields. Related fields can be accessed using dot-walking or reference fields but are not the same as Related Lists.

Explanation of Incorrect Options:References from Certified System Administrator (CSA) Documentation:

In ServiceNow, the Service Catalog application allows administrators to create, configure, and manage catalog items that users can request. To create a new catalog item, administrators must access the correct module within the Service Catalog application.

Maintain Categories (Option A) ❌

This module is used to create and manage categories within the Service Catalog.

Categories are used to organize catalog items into logical groups but do not allow the creation of actual catalog items.

Maintain Items (Option B) ✅ (Correct Answer)

This module is used to create, edit, and manage catalog items in the Service Catalog.

It provides options to define the item name, description, fields, workflows, and pricing details.

Administrators use this module when they want to begin creating a new catalog item.

Content Items (Option C) ❌

This module is related to Content Management System (CMS) and Knowledge Base but is not used for creating standard Service Catalog items.

It allows administrators to create links to external content rather than actual requestable catalog items.

Items (Option D) ❌

The Items module displays catalog items but does not allow an administrator to create new ones.

It is primarily for viewing items rather than maintaining them.

Explanation of the Available Options:

The "Maintain Items" module is the only module where administrators can create, edit, and manage catalog items in ServiceNow.

Other options either relate to categories, content management, or viewing existing items, making them incorrect choices.

Why is "B. Maintain Items" the Correct Answer?
