正解:C
In Data Foundations, a low "Unique Locations" result indicates the CMDB contains duplicate Location records (or inconsistent location usage) that reduce data reliability for operational reporting and service analytics. This sits under "Insight" because the dashboard is highlighting a measurable quality issue, and the playbook provides a structured remediation path to restore confidence.
The recommended playbook-aligned process is to review the duplicate locations, determine which one is correct per the organization's naming and data standards, then re-point dependent records (CIs) to the correct Location before removing the duplicate. That sequence is essential: if you delete a duplicate location without first updating related CIs, you risk leaving CIs with missing/invalid location references, creating new completeness and correctness issues.
Option C matches best practice: validate which location record should remain, update all affected CIs (and any other dependent records) to use the correct location, and then delete (or retire/merge, depending on process controls) the duplicate record. Option B is risky because it skips validation and dependency updates.
Option D defeats the purpose of "Unique Locations" by allowing ongoing inconsistency. Option A is not the best fit because "Duplicate CI Remediator" is oriented toward CI duplicates; Location is typically a reference
/organization data domain and is handled through the specific remediation steps for that data set. Therefore, C is the recommended process.
