Benford's Law analyzes numerical data to detect anomalies based on the frequency distribution of leading digits. For it to be effective, the dataset must follow specific criteria, including consistency in measurement units. If transactions are in different currencies, the leading digits can vary due to currency conversion rates, invalidating the analysis.
* Double Integer Format (Option A):Benford's Law applies to any set of numerical data, not specifically double integers.
* Random Selection of Transactions (Option B):The data set must represent the entire population, not a random selection.
* Limiting Analysis to Standard Deviations (Option C):This is irrelevant to the application of Benford's Law.

The use of control totals satisfies the control objective of processing integrity. Processing integrity refers to the accuracy, completeness, timeliness, and validity of data processing. Control totals are a method of verifying the correctness of data processing by comparing the total value or count of a batch of transactions before and after processing. For example, if a batch of 100 invoices is entered into an accounting system, the total amount and number of invoices should match before and after processing. If there is a discrepancy, it indicates an error in data entry, transmission, or processing. Control totals help to ensure that no transactions are lost, duplicated, or altered during processing.

The primary purpose of a Business Impact Analysis (BIA) is to prioritize the restoration of systems and applications (D) based on their criticality to business operations. A BIA assesses the impact of disruptions, identifies critical processes, and determines recovery time objectives (RTOs) and recovery point objectives (RPOs).
Other options:
Identifying legal obligations (A) is an aspect of compliance but not the primary benefit of a BIA.
Providing updates on disaster risk levels (B) falls under risk management rather than BIA objectives.
Delineating employee responsibilities (C) is part of business continuity planning (BCP), not the BIA's main goal.
