How can you verify data integrity after a synchronization event?

• A. Reboot the device and trust previous state.
• B. Compare only timestamps.
• C. Check hash values, compare local and central versions, and verify status consistency.
• D. Use user feedback to verify data.

Answer: (C)

Verifying data integrity after a synchronization event hinges on confirming that the data received matches exactly what was sent and that both sides agree on the current state. Computing and comparing hash values for the data items on both the local and central systems provides a strong, content-based check: if the hashes match, the data blocks are identical; if they don’t, corruption or tampering likely occurred during transfer. In addition, comparing the local and central versions ensures you’re verifying that the two systems actually reflect the same data set and version, not just that a single file looks correct. Verifying status consistency ties everything together by confirming that the synchronization process completed cleanly and that both sides report the same outcome (for example, the same final sequence or state indicators), so you aren’t left with a partially updated or out-of-sync system. In contrast, rebooting the device and trusting the previous state doesn’t audit the actual data and can carry forward corrupted information. Relying only on timestamps can be misleading since timestamps can be identical or manipulated even when content differs. User feedback is unreliable for guaranteeing data integrity, as it doesn’t provide a deterministic check on data correctness. So, using hash comparisons, aligning with the central version, and verifying synchronization status gives you a comprehensive and dependable verification of data integrity after synchronization.
