Which practice best describes cross-channel data integrity verification in a voting protection system?

• A. Data integrity is performed only after a trip.
• B. One channel is always trusted and used for decision.
• C. Data integrity is ensured by comparing channel data, checksums, and cross-check logic before voting.
• D. Integrity checks are optional.

Answer: (C)

Cross-channel data integrity verification means you don’t rely on a single path for information. In a voting protection system, data comes through multiple independent channels, and you verify it by comparing the data from each channel, checking that their checksums or hashes match, and applying cross-check logic to ensure all channels agree before a vote is cast. This pre-vote consensus catches any mismatches, corruption, or tampering early, so decisions are based on consistent, verified data. If integrity checks are done only after a trip, or if you trust just one channel, you lose redundancy and risk proceeding with flawed information. Optional checks leave gaps that could allow undetected errors. So, comparing channel data, using checksums, and enforcing cross-check logic before voting is the robust approach.
