SANS 410 EXAM QUESTIONS
COMPLETE WITH CORRECT
ANSWERS
\Q\.Industrial Control System (ICS) - ANSWERS✔-A device, or set of devices, that manages,
commands, directs, or regulates the behavior of other devices or systems.
\Q\.ICS technology drivers - ANSWERS✔-Reliability, efficiency, safety, and ease of use.
\Q\.Discrete Process - ANSWERS✔-A process where a specified quantity of material moves as a
unit between workstations and each unit maintains it's unique identity.
\Q\.Batch Process - ANSWERS✔-A process that requires the mixing of raw materials, usually in a
heated vessel.
\Q\.Continuous Process - ANSWERS✔-A physical system that is represented through variables
that are smooth an uninterrupted in time.
\Q\.Hybrid Process - ANSWERS✔-reactive systems that intermix discrete and continuous
processes
\Q\.Process Engineer - ANSWERS✔-Designs the systems and processes used in the control
environment.
\Q\.Field Technician - ANSWERS✔-Maintains and repairs field devices
,\Q\.Programmer - ANSWERS✔-Implements the individual steps of the process code and deploys
the code to the controllers.
\Q\.Operator - ANSWERS✔-Works in the operations center remotely managing and controlling
the process
\Q\.Owner/Operators - ANSWERS✔-Purchases and uses the system. responsible for safe
operation and meeting regulations.
\Q\.Vendors - ANSWERS✔-Manufacture equipment and software
\Q\.Integrator - ANSWERS✔-Design, configure, test, train, and refresh systems.
\Q\.Government - ANSWERS✔-Implement guidance and regulation
\Q\.programmable logic controller (PLC) - ANSWERS✔-Computer based, solid-state devices that
control industrial equipment and processes.
\Q\.Remote terminal unit (RTU) - ANSWERS✔-Is installed to report local system information and
otherwise communicate with the upstream supervisory system. Connection typically made
using RS-232 or RS-485
\Q\.Intelligent Electronic Device (IED) - ANSWERS✔-Used in the power industry primarily, and
have limited function, but contain their own control logic and are usually micro-controller
based.
\Q\.Digital Protective Relay (DPR) - ANSWERS✔-Contains a micro-controller with the specific
purpose of measuring voltages and currents to determining whether a fault in the system exists.
, \Q\.Phasor Measurement Unit (PMU) - ANSWERS✔-Measure voltages and currents at principle
intersecting locations on a power grid and can output accurately timestamped voltage and
current phasors.
\Q\.Communication Gateway - ANSWERS✔-Facilitates data acquitting, storage, transmission and
protocol conversion though the industrial data network. Widely used to apply timestamp data
to logs for locally connected RTUs
\Q\.Communication Modules - ANSWERS✔-Connect FEP into networks of intelligent electronic
devices (IED) such as modbus or PROFIBUS.
\Q\.Real Time Operating System (RTOS) - ANSWERS✔-Runs on an embedded device and is
specialized in running programs with specific scheduling paradigm.
\Q\.Microkernels - ANSWERS✔-Responsible for Inter-process Communication (IPC), virtual
memory, and scheduling.
\Q\.Ladder Diagram (Ladder logic) - ANSWERS✔-Relay logic displays and drawings and was
written to be understood by technicians. Operates on rules rather than producers or functions.
Each pass over is called a scan, and it occurs many times per second.
\Q\.Function Block Diagram (FBD) - ANSWERS✔-Uses a series of blocks with a purpose and
inputs and outputs strung together. The order by which the blocks executes depends on the
Vendor.
\Q\.Structured Text (ST) - ANSWERS✔-A Series of instructions to include statements
implemented by a vendors use of an editor, such as programming languages like C.
