Preview Questions IT Systems Analyst | Role Specific Skill

Question 1: How does implementing a zero-trust architecture enhance the security of IT systems in a chemical plant?

Which action should you take?

Choose only one option

It allows access to all systems based on a trust model, minimizing restrictions

It reduces the complexity of securing critical infrastructure

It continuously verifies user identities and access privileges to minimize internal threats

It eliminates the need for multi-factor authentication across systems

Question 2: In creating a data integration model for a chemical process control system, what is the most effective way to handle time-series data from multiple sensors?

Which action should you take?

Choose only one option

By organizing the data into a structured relational database

By storing the data as flat files and processing them periodically

By using specialized time-series databases that optimize for temporal data

By indexing the data using a non-relational database

Question 3: In a chemical plant's integrated data model, how can time synchronization be effectively managed across multiple systems?

Which action should you take?

Choose only one option

By using only one central time server for all data points

By using a time-stamped database and synchronization protocols such as NTP (Network Time Protocol)

By manually adjusting the time in each system based on local time zones

By allowing each system to operate independently without synchronizing

Question 4: What is the impact of security architecture on system design in chemical and petrochemical industries?

Which action should you take?

Choose only one option

Security architecture focuses solely on endpoint devices, not network infrastructure

Security architecture is crucial for protecting critical process data and ensuring system integrity

Security architecture only involves user access control and passwords

Security architecture is irrelevant as all process data is already encrypted

Question 5: Why is stakeholder involvement important in the SDLC for developing software in a chemical plant?

Which action should you take?

Choose only one option

It ensures that the software meets business needs and regulatory requirements, reducing the need for rework

Stakeholders only need to be involved in the final approval stage

Stakeholder involvement is only necessary in the testing phase

It complicates the development process by introducing conflicting priorities

Question 6: How does the documentation phase in SDLC impact the long-term maintenance of software used in petrochemical process control systems?

Which action should you take?

Choose only one option

It simplifies deployment by eliminating the need for user manuals

It is not necessary if the system is already well-tested and operational

It speeds up development by reducing the need for detailed documentation

It ensures that detailed records of system architecture, features, and code are available for future modifications and troubleshooting
