In the data-integrity acronym ALCOA, the letter C stands for:
B. Contemporaneous
Attributable, Legible, Contemporaneous, Original, Accurate; ALCOA+ adds complete, consistent, enduring and available.

Farmers' names, phone numbers and bank details held by a dairy are generally subject to:
A. Data-protection laws
Many countries' data-protection laws require a lawful purpose, minimal collection, security and data-subject rights.

Which IEC 61131-3 language resembles relay wiring and is widely used by plant electricians?
A. Ladder diagram
Ladder diagram uses rungs of contacts and coils; structured text is a high-level text language; SFC describes sequences.

The phases of a CIP cycle (pre-rinse, alkali, rinse, acid, final rinse) are most naturally programmed in a PLC with:
D. Sequential function chart
SFC models steps and transitions, matching sequential processes.
Further reading: IEC 61131-3
When a result falls outside specification, a well-configured LIMS will:
B. Flag it automatically for review
Automatic specification checks flag OOS results; deleting or hiding them is a serious integrity breach.
Further reading: ASTM E1578
In CIP systems, conductivity sensors are used mainly to:
C. Detect water–milk–detergent interfaces
Detergents conduct strongly, water weakly and milk moderately, so conductivity marks phase changes.

Rising electrical conductivity of milk from one quarter of an udder, recorded by a milking system, is an early sign of:
D. Mastitis
Inflammation increases sodium and chloride in milk, raising conductivity.

Compared with IT security, OT security gives highest priority to:
A. Availability and safety
A stopped pasteuriser or unsafe refrigeration system matters more than a leaked file.
Further reading: NIST SP 800-82
Offline backups of PLC programs, HMI configurations and recipes are essential because they:
B. Allow recovery after ransomware or equipment failure
Backups not reachable from the network survive encryption by attackers.
Further reading: NIST Cybersecurity Framework
The first foundation of an OT security programme is:
D. An inventory of OT assets and connections
What is not known cannot be protected; inventory comes before segmentation and monitoring.
