RAM Risk Management & Mitigation 3

Question 1

In a fault tree analysis (FTA), what does an AND gate signify about the events connected to it?

Accepted Answer

All input events must occur simultaneously for the top event to occur

Answer

An AND gate in FTA requires all connected input events to occur concurrently for the output (top) event to result.

Question 2

Which type of redundancy uses identical components to increase system reliability?

Accepted Answer

Active parallel redundancy

Answer

Active parallel redundancy uses identical components operating simultaneously so any one can sustain function if others fail.

Question 3

A residual risk is best described as the risk that remains after:

Accepted Answer

Mitigation controls have been applied

Answer

Residual risk is the level of risk that persists after all planned mitigation and control measures have been implemented.

Question 4

What does ALARP stand for in risk management?

Accepted Answer

As Low As Reasonably Practical

Answer

ALARP means risks should be reduced 'As Low As Reasonably Practicable,' balancing risk reduction benefits against cost and effort.

Question 5

In RAM risk management, a 'common cause failure' (CCF) occurs when:

Accepted Answer

A single event causes multiple redundant components to fail simultaneously

Answer

CCF is a single root cause that defeats redundancy by causing multiple components to fail at the same time.
