Question 1
For a focused assessment of Basic Hydraulic Systems, which set keeps all three
considerations within the appropriate area? The assessment must address “Starting
up” together with two other relevant considerations.
A. reservoirs; Interpreting electrical power and control circuit schematics; Adhering to fluid
power systems safety rules
B. Adhering to process control system safety rules; Starting up; Adhering to fluid power systems
safety rules
C. reservoirs; Starting up; lubricators - FRL units
D. reservoirs; Starting up; Adhering to fluid power systems safety rules
Correct Answer: D
Full Explanation:
For Basic Hydraulic Systems, the relevant details are: Servicing hydraulic fluid, reservoirs, and fluid
filters. For Basic Hydraulic Systems, the relevant details are: Starting up, shutting down, and adjusting
operating pressures in hydraulic power units (HPUs). The relevant consideration under Basic Hydraulic
Systems is “Adhering to fluid power systems safety rules”. Each alternative replaces one relevant
consideration with a concern from another area.
Question 2
A review centers on “thermal overloads”. Which area most directly addresses this
concern?
A. Maintenance Operations
B. Basic Hydraulic Systems
C. Electrical Systems
D. Maintenance Welding
Correct Answer: C
Full Explanation:
For Electrical Systems, the relevant details are: Selecting, installing, testing, and replacing fuses,
circuit breakers, and thermal overloads. For Maintenance Operations, the relevant details are:
Selecting and safely utilizing proper hand tools, power tools, and precision measuring instruments. The
distinction is the subject being evaluated, not merely the fact that both activities occur in the same
professional setting.

Question 3
When evaluating “monitoring basic control programs to and from programmable
controllers”, which topic should guide the review?
A. Process Control Systems
B. Electronic Control Systems
C. Maintenance Piping
D. Basic Pneumatic Systems
Correct Answer: B
Full Explanation:
For Electronic Control Systems, the relevant details are: Transferring, backing up, and monitoring
basic control programs to and from programmable controllers. The relevant consideration under
Maintenance Piping is “Measuring, cutting, threading, bending, and preparing piping and tubing
materials”. The distinction is the subject being evaluated, not merely the fact that both activities occur
in the same professional setting.
Question 4
A reviewer makes the following claims. Statement 1: “Operating” is a concern within
Maintenance Operations. Statement 2: “Troubleshooting electric motor relay control
circuits, solenoid-operated fluid power circuits, and dual-voltage motor configurations”
is a concern within Electrical Systems. How should these claims be evaluated?
A. Statement 1 is inaccurate; statement 2 is accurate.
B. Statement 1 is accurate; statement 2 is inaccurate.
C. Both statements are accurate.
D. Neither statement is accurate.
Correct Answer: C
Full Explanation:
Statement 1 is accurate. For Maintenance Operations, the relevant details are: Operating, monitoring,
and interpreting machine operation status. Statement 2 is accurate. The relevant consideration under
Electrical Systems is “Troubleshooting electric motor relay control circuits, solenoid-operated fluid
power circuits, and dual-voltage motor configurations”.

Question 5
Which area is being examined when the task involves “shutting down”?
A. Electronic Control Systems
B. Basic Hydraulic Systems
C. Servicing and maintaining pneumatic support equipment
D. Maintenance Welding
Correct Answer: B
Full Explanation:
For Basic Hydraulic Systems, the relevant details are: Starting up, shutting down, and adjusting
operating pressures in hydraulic power units (HPUs). For Maintenance Welding, the relevant details
are: Adhering to welding safety rules, hot work permits, and fire prevention protocols. The distinction
is the subject being evaluated, not merely the fact that both activities occur in the same professional
setting.
Question 6
When evaluating “Replacing control wiring, terminal connections, soldered joints, and
testing/replacing control transformers”, which topic should guide the review?
A. Process Control Systems
B. Servicing and maintaining pneumatic support equipment
C. Electrical Systems
D. Electronic Control Systems
Correct Answer: C
Full Explanation:
The relevant consideration under Electrical Systems is “Replacing control wiring, terminal connections,
soldered joints, and testing/replacing control transformers”. For Servicing and maintaining pneumatic
support equipment, the relevant details are: Servicing and maintaining pneumatic support equipment
(air filters, regulators, and lubricators - FRL units). The distinction is the subject being evaluated, not
merely the fact that both activities occur in the same professional setting.
