Question 1: 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

Question 2: What is the difference between "soft" and "firm" real-time systems?

Which action should you take?

Choose only one option

Soft systems can tolerate occasional deadline misses; firm cannot

Firm systems are used for critical applications

Firm systems always have higher throughput

Both are interchangeable terms

Question 3: How would you address data integrity challenges in a real-time system when collecting sensor data in a chemical processing environment?

Which action should you take?

Choose only one option

Use high-frequency sampling for all sensors

Limit data collection to only critical sensors

Rely on signal averaging for data collection

Use time-stamped data and ensure synchronization across sensors

Question 4: When integrating control systems for a petrochemical refinery, how do you ensure real-time monitoring and control across multiple subsystems?

Which action should you take?

Choose only one option

Implementing edge computing on-site to process data locally

Deploying dedicated controllers for each subsystem

Using a centralized SCADA system for all subsystems

Integrating IoT technologies for real-time data acquisition

Question 5: What is the advantage of using SPI over I2C in embedded systems?

Which action should you take?

Choose only one option

Higher data transfer rates

Fewer pins required

Simpler protocol implementation

Lower power consumption

Question 6: What is the purpose of a latch in PLC programming, and how does it affect the state of a control process in a petrochemical plant?

Which action should you take?

Choose only one option

It continuously updates the output during the control process

It holds an output state until reset, even after the input condition is removed

It reduces the power consumption of the process

It resets the process state after a certain condition is met
