TheConfiguration Management Database (CMDB)in ServiceNow is a centralized repository that stores information aboutConfiguration Items (CIs), their attributes, and relationships. It plays a crucial role in IT Service Management (ITSM), helping organizations track assets, dependencies, and service impacts.
Thefour correct concepts associated with the CMDBare:
The CMDB is structured usingtablesandfieldswithin the ServiceNow database.
Different tables store different types ofConfiguration Items (CIs)such as servers, applications, and network devices.
Example CMDB Tables:
cmdb_ci(Base CMDB Table)
cmdb_ci_server(Stores server-specific CIs)
cmdb_ci_database(Stores database-related CIs)
Each table hasfieldsthat store attributes (e.g.,Serial Number, IP Address, Location).
The CMDB is essentially adatabasethat holds detailed information about IT assets and their relationships.
It enables organizations to maintain an accurate inventory of IT infrastructure.
The database helps withincident management, change management, and asset tracking.
Dependency Viewprovides agraphical representationof how Configuration Items (CIs) are related.
This visualization helps IT teamsunderstand dependencies, impact analysis, and root cause analysis.
Example:
If adatabase servergoes down, theDependency Viewcan show which applications and services will be affected.
The CMDB supports variousIT Service Management (ITSM) processes, such as:
Incident Management(linking incidents to affected CIs)
Change Management(analyzing the impact of changes on CIs)
Problem Management(identifying root causes of recurring issues)
The CMDB ensures that these processes operate with accurate and updated asset data.
1. Tables and Fields (Correct)2. A Database (Correct)3. The Dependency View (Correct)4. Service Processes (Correct) Why the Incorrect Option is Wrong:B. User Permissions (Incorrect) Whileuser permissions(such as roles and access controls) exist in ServiceNow, they arenot a fundamental concept of the CMDB itself.
Permissions (likecmdb_readoradmin) controlwho can access and modify the CMDB, but they are notcore CMDB components.
AnIT administratorwants to checkwhich business services depend on a specific database serverbefore performing maintenance.
Using theCMDB Dependency View, they see that the database server is linked to anemail serviceand acustomer portal.
This insight helps them plan achange requestto notify impacted users before the server is taken offline.
