問題 #188
(Choose 2 options)
The following Reconciliation Rules were configured for ServiceNow, Altiris, and SCCM for the Windows Server (cmdb_ci_win_server) class:

Which statements are true?

A. Data collected with a discovery source of Altiris can update records inserted by SCCM into the Windows Server table.
B. Data collected with a discovery source of SCCM can be inserted as new records in the Windows Server table.
C. Data collected with a discovery source of SCCM can update any record in the Windows Server table because it has the highest priority number.
D. Data collected with a discovery source of ServiceNow can insert new records into the Windows Server table, but cannot update records created by Altiris or SCCM.

答案：A,B

解題說明：
This question tests understanding of reconciliation source priority in the Identification and Reconciliation Engine (IRE) in ServiceNow.
In reconciliation rules, lower numeric values represent higher priority. Therefore, the priority order is:
ServiceNow (100) - highest authority
Altiris (200)
SCCM (300) - lowest authority
Why A is correct
Because Altiris (200) has higher priority than SCCM (300), data from Altiris can update records originally inserted by SCCM. This is exactly how reconciliation precedence works-higher-priority sources can overwrite lower-priority ones.
Why C is correct
SCCM, even though it has the lowest priority, is still an authorized discovery source. It can insert new records into the Windows Server table when no existing CI is identified. Priority only affects updates, not the ability to create records.
Why B is incorrect
ServiceNow (priority 100) can update records from Altiris and SCCM because it has the highest priority. The statement incorrectly claims it cannot.
Why D is incorrect
SCCM does not have the highest authority. A higher numeric value means lower priority, so SCCM cannot update records created by higher-priority sources.

問題 #189
The Apache Web Server Identification Rule is configured with the following criterion attributes:
Class
Configuration file
Version

Yesterday, an Apache Web Server CI was discovered as part of Service Mapping. Today, the application owner upgraded Apache to a different version and reran discovery of the service.
What will happen in the CMDB?

A. The Apache Web Server CI will be reclassified as a Web Server CI.
B. A duplication error will occur.
C. A new Apache Web Server CI is created.
D. The existing Apache Web Server CI will be reconciled and its version will be updated.

答案：C

解題說明：
This scenario hinges on how the Identification and Reconciliation Engine (IRE) in ServiceNow evaluates identification rules.
The identification rule for the Apache Web Server class includes Version as part of the identifier criteria, along with Class and Configuration file. Identification rules must match all criterion attributes exactly for an incoming record to be identified as an existing CI and reconciled.
Yesterday's discovery created an Apache Web Server CI with a specific version value. When Apache is upgraded and discovery is rerun, the Version attribute changes. Because Version is part of the identifier, the incoming record no longer matches the existing CI's identifier entry. As a result, the IRE cannot identify the existing CI as the same configuration item.
When identification fails and no matching identifier entry is found, the IRE proceeds to insert a new CI record rather than updating the existing one. This behavior is intentional and protects the CMDB from incorrectly reconciling records that no longer meet identification criteria.

問題 #190
A CMDB Administrator needs to configure a new application identification rule that considers the potential for the same application installed more than once on the same server.
Which is the best choice of a criterion attribute?

A. Version
B. Class
C. Configuration File Name
D. Port
E. Configuration File Path

答案：E

解題說明：
The correct answer is Configuration File Path . When the same application can be installed more than once on the same server, the identification rule must use an attribute that can distinguish one installed instance from another. Configuration File Path is stronger than file name because the same file name can exist in multiple installation directories. It is also stronger than version because multiple instances may run the same version.
Port can help in some cases, but ports may be reused, changed, or not consistently available for every application pattern. Class is too broad because it only identifies the type of CI, not the specific application instance. A path-based criterion is more precise because it identifies where that application instance is installed on the server. Therefore, Configuration File Path is the best criterion attribute for preventing incorrect matches between multiple instances.

問題 #191
The Configuration Management team wants to confirm that all servers in the CMDB actually exist in the data center. Which CMDB Data Manager policy type would the team create? (Choose 1 option)

A. Retire
B. Archive
C. Delete
D. Certification
E. Attestation

答案：E

問題 #192
The CMDB Configuration Management team wants to manage de-duplication tasks generated from data ingested into the CMDB via the Identification and Reconciliation Engine (IRE). In which area of the CMDB Workspace can they locate these de-duplication tasks?

A. CMDB feature adoption tile under the Insights tab
B. Important actions tile under the Home tab
C. Total status under the My Work tab

答案：C

解題說明：
In ServiceNow, de-duplication tasks generated by the Identification and Reconciliation Engine (IRE) are operational governance tasks that require action by CMDB administrators or data owners. These tasks are surfaced in a role-based and actionable manner to ensure they are addressed promptly.
Within the CMDB Workspace, such tasks are accessed via the My Work tab, specifically under the Total status section. This area consolidates all actionable CMDB-related work items assigned to the user or their groups, including duplicate CI remediation tasks, data certification tasks, attestation requests, and lifecycle governance actions generated by CMDB Data Manager and IRE processes.
