it was determined that replication of a critical database used by two business units failed. Which of the following should be of GREATEST concern1?
Correct Answer: C
The lack of integrity of data is the greatest concern when replication of a critical database used by two business units failed. Data integrity means that the data is accurate, complete, consistent, and reliable. If the replication failed, it means that the data in the primary and secondary databases may not be synchronized and may have discrepancies or errors. This could affect the quality and reliability of the data and the business processes that depend on it. The other options are not as concerning as the lack of integrity of data, as they are related to the efficiency, cost, or confidentiality of the data, which are less critical than the accuracy and reliability of the data.
