Start CMDB PracticeAn administrator creates a custom identification rule for a new class. The rule has two entries: Entry 1 uses 'serial_number' (weight 100), and Entry 2 uses 'mac_address' (weight 50). When a payload arrives containing both attributes, how does the IRE evaluate the rule entries?
Explanation: IRE evaluates identification rule entries in order of their priority or weight, or matches using the first matching entry based on configuration criteria.
A business service map displays a critical application server as disconnected from its underlying database. Upon investigation, the database CI was updated with a new IP address, breaking the relationship. Which ServiceNow feature helps automatically maintain relationships when attributes change?
Explanation: Service Mapping and Discovery rely on IRE and pattern synchronization, but relationship maintenance is often preserved through automated discovery or reference qualifier linkage. When considering CMDB core mechanisms, IRE handles updates, and relationship rules or dynamic CI groups maintain groupings.

Explanation: CMDB Health consists of three pillars: Completeness, Correctness, and Compliance.
Which TWO of the following tables are standard base or parent tables in the CMDB hierarchy? (Choose two.)
