CSA Configuration Management Database (CMDB) 2 — Questions and Answers
Question 1: Which tool in ServiceNow provides a visual map of CI relationships?
- Dependency Views (formerly Service Maps) (Correct answer)
- CMDB Health Dashboard
- Performance Analytics
- Discovery Schedules
Correct answer: Dependency Views (formerly Service Maps)
Dependency Views (formerly Service Maps) provides a graphical representation of CI relationships, showing how CIs are connected and depend on each other.
Question 2: What is the Identification and Reconciliation Engine (IRE) used for in ServiceNow CMDB?
- To identify and deduplicate CI records while reconciling data from multiple sources (Correct answer)
- To generate compliance reports for CMDB audits
- To automatically retire outdated CI records
- To synchronize CMDB data with external ticketing systems
Correct answer: To identify and deduplicate CI records while reconciling data from multiple sources
The IRE identifies existing CIs to prevent duplicates and reconciles CI attribute data coming from multiple discovery or import sources into a single authoritative record.
Question 3: Where is relationship data between CIs stored in ServiceNow?
- cmdb_rel_ci table (Correct answer)
- cmdb_ci table
- sys_relationship table
- task_rel table
Correct answer: cmdb_rel_ci table
The cmdb_rel_ci table stores all relationship records between CIs, capturing the relationship type and the source and target CI references.
Question 4: What does the 'Runs on::Hosted by' relationship type indicate between two CIs?
- A software or application CI runs on an infrastructure CI that hosts it (Correct answer)
- One CI provides power or cooling to another CI
- A CI is physically contained within another CI
- A CI monitors the availability of another CI
Correct answer: A software or application CI runs on an infrastructure CI that hosts it
The 'Runs on::Hosted by' relationship indicates that a software or application CI runs on a hardware or infrastructure CI (like a server), establishing a hosting dependency.
Question 5: What is a CMDB baseline used for?
- To capture a snapshot of CI attributes at a point in time to compare against future states (Correct answer)
- To set minimum performance thresholds for CI health metrics
- To define default attribute values for newly created CI records
- To establish approval workflows for CI configuration changes
Correct answer: To capture a snapshot of CI attributes at a point in time to compare against future states
A CMDB baseline captures a snapshot of CI attributes at a specific point in time, enabling comparison to detect unauthorized changes or configuration drift.
Question 6: Which of the following is a key benefit of maintaining a well-populated CMDB?
- Improved impact analysis during incident and change management processes (Correct answer)
- Automatic resolution of all IT incidents without human intervention
- Elimination of the need for change approval workflows
- Automatic generation of service catalog items for end users
Correct answer: Improved impact analysis during incident and change management processes
A well-populated CMDB enables accurate impact analysis, helping teams understand which services and users are affected when a CI experiences an issue or undergoes a change.
Question 7: What is the purpose of the CMDB Health dashboard in ServiceNow?
- To measure and display metrics about CMDB data quality, completeness, and compliance (Correct answer)
- To monitor real-time performance of servers stored as CIs
- To track the number of open incidents associated with each CI
- To display the results of Discovery schedule executions
Correct answer: To measure and display metrics about CMDB data quality, completeness, and compliance
The CMDB Health dashboard provides metrics about CI data quality, completeness, correctness, and compliance, helping administrators identify and address data quality issues.
