Question 2: CI Class Manager
In CMDB management, select three appropriate items that can be configured using the CI Class Manager.
- A. Identification Rules (Definition of unique keys to identify CIs)
- B. Reconciliation Rules (Write priority for each data source)
- C. Health Metrics (Thresholds for Completeness, Correctness, and Compliance)
- D. Business Service Offering (Price definition for Business Service Offerings)
- E. Application Service (Creation and mapping of new Application Services)
【Correct Answer】 A. Identification Rules, B. Reconciliation Rules, C. Health Metrics
【Detailed Explanation】
Why A, B, and C are correct: The CI Class Manager serves as a control panel for defining the behavior of each CMDB “class” (table).
- A (Identification Rules): You define rules for each class to determine whether incoming data matches an existing CI (e.g., considering CIs to be the same if their serial numbers match).
- B (Reconciliation Rules): When the same attribute (e.g., CPU count) is reported by multiple sources (such as Discovery, ServiceNow Agent Client Collector, or manual input), these rules define which source is trusted and takes precedence.
- C (Health Metrics): You can customize the calculation criteria for “CI health” displayed on the CMDB dashboard (e.g., defining which fields must be populated to avoid being flagged as “Incomplete”) on a per-class basis.
Why the other options are incorrect:
- D (Business Service Offering): This data is defined within the Service Portfolio Management module or via catalog management; it is not a configuration for the CMDB class structure (schema).
- E (Application Service): This represents the “data registration” task of creating specific system configurations. The CI Class Manager manages the framework (rules) for the “Application Service class,” not the creation of individual service instances.
If these questions aren’t enough or you want extra peace of mind, I have curated a collection of 100 essential practice questions, based on my own experience passing the exam.
This is my personal answer to the question, “Where should I start?”
You no longer need to spend hours scouring through endless documentation. By working through these 100 carefully selected questions—which I believe are absolutely critical for passing—you can significantly increase your success rate.
Having taken the exam myself, I can confidently say this: whether or not you know these 100 questions is likely to be the deciding factor in your result.
