1. What is the purpose of the CMDB in ServiceNow?
It centralizes all configuration data in one place.
Helps understand how services and systems connect.
Supports quick impact analysis during incidents.
Reduces guesswork in change management.
Gives better visibility into IT operations.
Improves decision-making across IT teams.
2. How do you define a Configuration Item (CI)?
A CI is any component that needs to be tracked in the CMDB.
It can be a server, app, database, or even a business service.
Each CI has attributes and relationships.
It forms the building block of CMDB.
CIs help identify dependencies during changes.
They’re crucial for IT stability and traceability.
3. What’s the difference between a CI and an Asset?
A CI focuses on operational relevance and dependencies.
An asset is about ownership, cost, and procurement details.
CIs live in the CMDB; assets live in the Asset tables.
One CI can map to one or more assets.
Assets are tracked from a financial point of view.
CIs are tracked from a technical point of view.
4. What are base tables in ServiceNow CMDB?
cmdb is the parent table for all CMDB data.
cmdb_ci holds core configuration items.
cmdb_rel_ci manages relationships between CIs.
Child tables like cmdb_ci_server or cmdb_ci_appl hold specific CI types.
Understanding the structure improves queries and reporting.
All CMDB data flows from these base tables.
5. How are CI relationships structured, and why are they important?
Relationships define how CIs depend on each other.
For example, a server “hosts” an application.
These links are stored in cmdb_rel_ci.
They’re critical for impact and root cause analysis.
They also power service maps and dependency views.
Without them, CMDB becomes just isolated data points.
