Types of Exam Questions

All Red Seal exam questions are written in multiple-choice format. A multiple-choice question consists of question followed by four possible responses (A, B, C, D). Every question has exactly one correct answer and three incorrect options. They are not misleading or trick questions, but the incorrect options are not always obvious.

There are three types of questions that you will see on Red Seal Exams:

Knowledge and Recall
Procedural and Application
Critical Thinking

Knowledge and Recall

This type of question tests your ability to recall and understand definitions, facts and principles.

For this trade, between 45 and 55% of questions that are this type.

Example of a Knowledge and Recall Question:

What is the purpose of a slip ring?

Prevents the turntable from slipping.
Prevents loosening of turntable bolts.
Allows the crane to slew freely without damaging the power supply.
Allows height to be added to the crane without damage to the power supply.

Answer: C

Procedural and Application

This type of question tests your ability to apply your knowledge of procedures to a situation.

For this trade, between 25 and 35% of questions are this type.

Example of a Procedural and Application Question:

What is the procedure to mount the climbing collars to the floor when preparing for a bottom-climbing procedure?

Level, bolt, then grout the collars.
Grout, bolt, then level the collars.
Level, grout, then bolt the collars.
Bolt, grout, then level the collars.

Answer: A

Critical Thinking

This type of question tests your ability to interpret data, solve problems and arrive at valid conclusions.

For this trade, between 15 and 25% of questions are this type.

Example of a Critical Thinking Question:

When lifting a heavy load at maximum radius, boom and tower deflection occurs. What is the result?

The tower compresses and damages the turntable.
Radius increases causing the load to swing out.
A side load occurs and the boom fails.
The crane tilts forward causing swing brakes to apply.

Answer: B
