Question 1

A payroll application server and its database server are both discovered successfully. Discovery shows the application process opening connections to the database listener, and the CMDB now contains a relationship between the application component and the database CI. What best explains how the relationship was created?

Answer choices

  • A. Discovery detected connection and process dependency evidence and created the relationship automatically (Correct)

  • B. The relationship was created only because the database class was marked Principal

  • C. CMDB Health generated the relationship after detecting a missing dependency

  • D. A reconciliation rule converted matching attributes into a dependency relationship

Explanation

Discovery detected connection and process dependency evidence and created the relationship automatically. Discovery can create relationships when it observes concrete runtime evidence such as processes, listening ports, and network connections between the discovered components.

Question 2

A global company must ingest cloud infrastructure, on-premises servers, and a quarterly facilities CSV into the CMDB. Which three patterns best fit the different data sources?

Answer choices

  • A. Service Graph Connector for supported cloud resources (Correct)

  • B. MID Server-backed Discovery for reachable on-premises servers

  • C. Scheduled import set and transform map for the quarterly facilities CSV

  • D. Manual list edits for all three sources

  • E. Principal class settings as the ingestion engine

Explanation

Service Graph Connector for supported cloud resources — A maintained connector provides supported mappings and an established IRE-aware ingestion path, reducing the custom code and maintenance burden of a bespoke integration.

MID Server-backed Discovery for reachable on-premises servers — A MID Server runs Discovery and JDBC activities inside the restricted network and communicates outbound to the instance, avoiding direct inbound access to protected systems.

Scheduled import set and transform map for the quarterly facilities CSV — Import sets and transform maps provide a repeatable staging and field-mapping process for batch files, with IRE-aware handling added when the target data is a CI.

Question 3

A dashboard team already has strong reporting tools, but every department modeled “service” differently before CSDM. Why are the reports still difficult to trust?

Answer choices

  • A. Reporting tools cannot compensate for inconsistent service definitions and relationships underneath (Correct)

  • B. CSDM prevents dashboards from reading service records

  • C. Business services must be discovered by SNMP before reports work

  • D. Principal classes must be disabled for every service record

Explanation

Reporting tools cannot compensate for inconsistent service definitions and relationships underneath. CSDM supplies consistent concepts and relationship patterns so teams can report on services without reconciling incompatible local definitions.

Question 4

A file-based server import must use IRE so incoming rows are matched, inserted or updated, and reconciled according to source precedence. Put the high-level process in the correct order.

Answer choices

  • A. Transform logic invokes CMDBTransformUtil or an equivalent IRE-aware CMDB path

  • B. Source rows land in an import set staging table

  • C. IRE applies identification logic to determine whether each CI is new or existing

  • D. Reconciliation rules determine whether source values may update governed attributes

Explanation

Order: B → A → C → D

Source rows land in an import set staging table → Transform logic invokes CMDBTransformUtil or an equivalent IRE-aware CMDB path → IRE applies identification logic to determine whether each CI is new or existing → Reconciliation rules determine whether source values may update governed attributes

The source rows must first be staged in the import set. Transform processing can then invoke CMDBTransformUtil or another IRE-aware path; IRE identifies whether each payload represents a new or existing CI, and reconciliation determines whether the source may update each governed attribute.

Question 5

A disk CI has serial number, model, capacity, and owner populated. It was updated yesterday by Discovery and has no duplicate candidates. CMDB Health still flags it because it is not linked to any host CI. Which rule type most directly explains the flag?

Answer choices

  • A. Orphan rule (Correct)

  • B. Reconciliation rule

  • C. Principal class rule

  • D. Identification rule

Explanation

Orphan rule. Orphan and relationship-correctness checks identify CIs that are missing required relationships or are disconnected from the model expected for their class.
