Question 1: How does a data lake differ from a traditional data warehouse in the context of chemical process data modeling?

Which action should you take?

Choose only one option

A data lake is more expensive to implement than a data warehouse

A data lake only stores historical data, whereas a data warehouse stores real-time data

A data lake requires fewer security measures than a data warehouse

A data lake allows the storage of unstructured, raw data, while a data warehouse stores structured, processed data

Question 2: During the design phase of SDLC in a chemical industry software development project, which factor is most critical to ensure successful system integration?

Which action should you take?

Choose only one option

The design must focus on cost reduction without considering system constraints

The design must focus on aesthetics and user experience only

The design must align with both functional requirements and operational constraints of the plant

The design must prioritize speed and performance, irrespective of regulatory standards

Question 3: In the SDLC, what role does the design phase play in developing software for chemical and petrochemical processes?

Which action should you take?

Choose only one option

It identifies potential bottlenecks by analyzing the hardware resources

It tests the software to verify its compatibility with existing systems

It defines the architecture, interfaces, and components, ensuring that the system meets all technical and business requirements

It is solely responsible for coding and debugging the software

Question 4: What is the role of system architecture in achieving compliance with industry regulations such as ISA-88 in the chemical industry?

Which action should you take?

Choose only one option

Focusing on manual control and operator intervention

Ensuring that the system supports batch process control standards and documentation requirements

Reducing the number of sensors and instrumentation in the process

Minimizing data storage and backup requirements

Question 5: How does an intrusion detection system (IDS) contribute to the security of a chemical plant's IT infrastructure?

Which action should you take?

Choose only one option

By encrypting sensitive data transmitted across the network

By limiting access to only internal users within the network

By ensuring compliance with industry-specific regulations

By identifying suspicious activities and potential security breaches in real-time

Question 6: What is the primary purpose of conducting a vulnerability assessment in the IT infrastructure of a chemical plant?

Which action should you take?

Choose only one option

To identify and fix weaknesses in the system that could be exploited by attackers

To reduce the number of devices connected to the network

To ensure compliance with industry regulations

To measure the system's overall performance and optimize it
