Preview Questions IT Systems Analyst | Role Specific Skill

Question 1: What is the impact of scaling a cloud-based IT infrastructure in a chemical plant's system architecture?

Which action should you take?

Choose only one option

It increases the risk of data security breaches

It leads to a higher cost due to increased bandwidth usage

It requires a complete system redesign

It increases flexibility and resource management while reducing hardware costs

Question 2: What is the role of redundancy in ensuring high availability in chemical plant IT systems?

Which action should you take?

Choose only one option

Redundancy is only required for power supply systems, not IT infrastructure

Redundancy only increases hardware costs without offering significant benefits

Redundancy ensures that backup systems are available in case of failure, minimizing downtime and maintaining availability

Redundancy reduces operational efficiency by requiring more maintenance

Question 3: How can an IT Systems Analyst effectively mitigate the risk of cyber-attacks on a chemical plant's SCADA system?

Which action should you take?

Choose only one option

By reducing the frequency of updates to critical system software

By isolating the SCADA system from external networks entirely

By relying only on physical security measures, ignoring cybersecurity

By implementing a multi-layered security approach including firewalls, encryption, and intrusion detection systems

Question 4: What is the role of data normalization in the integration of multiple data sources in a chemical plant?

Which action should you take?

Choose only one option

To eliminate any outlier data from the system

To remove any discrepancies between physical and digital sensor readings

To compress data into smaller sizes for storage

To ensure that data from different sources can be compared and analyzed on a common scale

Question 5: In designing a system architecture for a petrochemical plant's process control, what is the key challenge when incorporating IoT devices?

Which action should you take?

Choose only one option

Ensuring compatibility with legacy IT systems

Reducing the operational cost of IoT device installation

Managing the massive volume of real-time data from numerous sensors and devices

Minimizing energy consumption of IoT devices

Question 6: In system architecture analysis, what is the purpose of a data bus in an industrial IoT (IIoT) environment for chemical and petrochemical industries?

Which action should you take?

Choose only one option

To execute complex mathematical algorithms on-site

To store historical process data for later analysis

To manage the flow of data between devices and systems in a synchronized manner

To connect external devices to cloud-based storage systems
