SACA CERTIFICATION C-101 EXAM
(INDUSTRY 4.0 – BASIC OPERATIONS)
CERTIFICATION GUIDE QUESTIONS AND CORRECT
DETAILED ANSWERS WITH RATIONALES
100% GUARANTEED PASS!!
<LATEST VERSION>
1.
A production line uses sensors that automatically send real-time data to a central
system for monitoring machine status. This setup is best described as:
A. Manual assembly system
B. Isolated mechanical automation
C. Cyber-physical production system
D. Batch processing system
Answer: C
Rationale: Cyber-physical systems integrate physical machines with digital
monitoring and data exchange, which is a core feature of Industry 4.0.
2.
During a shift, a technician notices a machine is jammed. Before clearing the fault,
the technician must:
A. Increase machine speed to clear the jam
B. Apply lockout/tagout procedures
C. Restart the PLC program
D. Bypass the safety sensor
,Answer: B
Rationale: Lockout/Tagout (LOTO) ensures machines are fully de-energized to
prevent accidental startup during maintenance.
3.
Which Lean Manufacturing principle focuses on organizing tools so they are easy
to find and return?
A. Sustain
B. Shine
C. Set in order
D. Sort
Answer: C
Rationale: “Set in order” ensures all tools and materials are logically arranged for
efficiency.
4.
A PLC is primarily used to:
A. Design mechanical parts
B. Control automated industrial processes
C. Generate product blueprints
D. Measure material hardness
Answer: B
Rationale: PLCs are programmable devices used to control machines and
processes in automation systems.
,5.
A machine stops unexpectedly due to overheating. The best first action is to:
A. Restart immediately
B. Ignore and continue production
C. Report and follow diagnostic procedures
D. Increase load capacity
Answer: C
Rationale: Proper troubleshooting and reporting prevent equipment damage and
ensure safety.
6.
Which device is most commonly used for operator-machine interaction in Industry
4.0 systems?
A. Oscilloscope
B. HMI
C. Relay switch
D. Multimeter
Answer: B
Rationale: Human-Machine Interfaces (HMIs) allow operators to monitor and
control systems visually.
7.
In Lean systems, “waste reduction” primarily aims to:
A. Increase inventory levels
B. Eliminate non-value-adding activities
C. Increase machine downtime
D. Reduce employee training
, Answer: B
Rationale: Lean manufacturing focuses on removing inefficiencies that do not add
value.
8.
A technician measures a shaft diameter using a micrometer and records 12.50 mm.
This measurement represents:
A. Estimated value
B. Rough calculation
C. Precision measurement
D. Qualitative observation
Answer: C
Rationale: Micrometers provide high-precision quantitative measurements.
9.
Which robot type is most suitable for high-speed pick-and-place operations?
A. SCARA robot
B. Cartesian robot
C. Humanoid robot
D. Mobile rover
Answer: A
Rationale: SCARA robots are optimized for fast, repetitive assembly tasks.
