During the retrieve and compare process, the received FU databases are compared in what order to ensure no conflicts?

• A. Order last received
• B. Order first received
• C. Ordered by priority
• D. Ordered by size

Answer: (B)

When reconciling multiple FU databases, you establish a single reference point by using the first one that arrives as the baseline. The retrieve and compare process then checks each subsequent database against that baseline. If they match, no changes are made; if they differ, a conflict is detected and must be resolved explicitly rather than overwritten. This approach guarantees deterministic conflict handling and prevents later data from silently replacing earlier, potentially correct information.

Choosing any other order, like sorting by priority or size or always using the most recently received data, can obscure conflicts or overwrite the baseline, making it harder to detect inconsistencies and maintain data integrity.
