What are the three basic elements of a control loop?

Measurement, comparison, and actuation

Sensor, transmitter, and receiver

In an ICS, what is the typical data flow from a field device to a higher-level system like a historian?

HMI → Field device → Controller → Historian

Historian → HMI → Controller → Field device

Controller → Field device → HMI → Historian

Field device → Controller → HMI → Historian

In the Purdue model, which level typically contains the HMIs and supervisory control systems?

Level 2 – Supervisory control

What is the primary purpose of a Human-Machine Interface (HMI) in an industrial control system?

To store historical process data for long-term analysis

To automatically adjust process variables without human intervention

To convert sensor signals into digital values for the controller

To provide operators with a graphical view of the process and allow them to issue commands

A plant engineer wants to provide real-time production data to an enterprise reporting system. The data originates from sensors on the plant floor and is processed by PLCs. Which data flow path correctly represents the movement of this data from the field to the enterprise system?

Sensor → PLC → HMI → Historian → ERP

Sensor → HMI → PLC → ERP → Historian

PLC → Sensor → HMI → Historian → ERP

ICS Components & Architecture GICSP Practice Questions (Page 3)

Part of the ICS Fundamentals and Architecture domain, which makes up ~40% of our current practice bank. GIAC (SANS) does not publish an official question count, but from its 180-minute exam (~70–120 total, ~28–48 in this domain), expect 7–12 from this objective — we provide 53 practice questions to prepare you well beyond it.
