Which action should you take?

Choose only one option

Using real-time data sampling to verify system performance

Rewriting control logic to ensure compatibility

Using simulation tools to validate data exchange and control logic

Relying on visual inspection of system connections

Question 2: In a predictive maintenance scenario for a petrochemical plant, which feature engineering method is most useful for creating features from time-series sensor data?

Which action should you take?

Choose only one option

Feature scaling

Fast Fourier Transform (FFT)

Principal Component Analysis (PCA)

One-hot encoding

Question 3: When integrating safety systems with a DCS in a chemical plant, what is the primary concern?

Which action should you take?

Choose only one option

Increasing sensor accuracy for critical safety measurements

Using non-redundant controllers for cost savings

Reducing the response time of the safety systems

Ensuring the fail-safe operation of safety-related devices

Question 4: What is the most effective way to ensure the security of an integrated control system in a chemical manufacturing environment?

Which action should you take?

Choose only one option

Installing intrusion detection systems at entry points

All of the above

Using isolated networks for control and management systems

Implementing network firewalls and encryption protocols

Question 5: What is the importance of "latency" in real-time control systems for petrochemical plants, and how can it be minimized?

Which action should you take?

Choose only one option

Latency must be minimized to ensure fast reaction to critical events, achieved through optimized interrupt handling

Latency is not important as long as the system can recover from failures

Latency should only be minimized when communicating with remote systems

Latency can be ignored for non-critical tasks

Question 6: How do you ensure safe updates to firmware in embedded systems?

Which action should you take?

Choose only one option

Validate firmware checksum

Encrypt firmware files

All of the above

Use secure bootloaders
