A non-human threat for computer systems is a flood. In which situation is a flood always a relevant threat?

The correct answer is B. When computer systems are kept in a cellar below ground level. Option B is correct because storing computer systems in a cellar below ground level makes flooding always a relevant threat - water naturally flows downward, so any flooding event (rain, burst pipes, rising groundwater) will directly endanger equipment at that location…

Question

A non-human threat for computer systems is a flood. In which situation is a flood always a relevant threat?

Options

  • AIf the risk analysis has not been carried out.
  • BWhen computer systems are kept in a cellar below ground level.
  • CWhen the computer systems are not insured.
  • DWhen the organization is located near a river.

Explanation

Option B is correct because storing computer systems in a cellar below ground level makes flooding always a relevant threat - water naturally flows downward, so any flooding event (rain, burst pipes, rising groundwater) will directly endanger equipment at that location regardless of other factors.

Why the distractors are wrong:

  • A is wrong because skipping a risk analysis doesn't create or increase a physical threat - floods exist as a threat based on location and environment, not on whether you've documented them.
  • C is wrong because insurance status has no bearing on whether a threat is physically present; lack of insurance affects financial recovery, not threat relevance.
  • D is a tempting distractor, but proximity to a river only increases flood probability - it doesn't make flooding always relevant. Rivers don't always flood, and many other flood sources (plumbing failures, storms) exist regardless of river proximity.

Memory tip: Think of it as a physics problem - water flows down, so a below-ground location is structurally vulnerable to flooding from any source, making it an inherent and constant risk rather than a conditional one.
