Correct answer: A
Explanation
You should enable Multisource CMDB to retain the history of all updates to attribute values from all discovery sources.
When multiple discovery sources attempt to update the same CI (Configuration Item) attribute, CMDB uses reconciliation rules to select the discovery source whose value updates the CI attribute.
Multisource CMDB retains details about the discovery source used for an update, and all the other discovery sources rejected for that update.
Without Multisource CMDB, data on rejected updates are discarded.
This includes details about the discovery sources of lower priority, along with their suggested attribute values.
Using Multisource CMDB, you can:
Control CI updates at the discovery source and CI attribute level.
Visualise the source of attribute values for each discovery source and at the attribute level.
Drive operational insights from Multisource CMDB data.
Modify reconciliation rules and then recompute and update CMDB data to reflect the updated reconciliation rules.
Revert CMDB data integration from a specific discovery source if, for example, you realise that the discovery source is not reliable. You can recompute CI attribute values while excluding the discovery source you want to ignore.
Improve data management and data quality by querying Multisource CMDB data.
