Which statement describes biometrics?

Question

Options

• AThe design of ergonomic factors that affect data center efficiency
• BData trending and analysis of the traffic passing a security check point
• CAccess control based on a unique physical characteristic of an individual
• DMonitoring of environmental factors, such as heat and humidity, that affect data center personnel

• A
  15% (8)
• B
  6% (3)
• C
  75% (40)
• D
  4% (2)

Explanation

Biometrics refers to access control that uses unique physical characteristics - fingerprints, retinal scans, facial recognition, voice patterns - to verify identity, making C correct.

A is wrong because ergonomic design relates to human factors engineering (comfort, efficiency), not identity verification. B is wrong because traffic analysis at a security checkpoint is a network monitoring concept, not biometric identification. D is wrong because monitoring heat and humidity describes environmental controls (like HVAC systems in data centers), which has nothing to do with individual identity.

Memory tip: Break down the word - bio (life/living) + metrics (measurement). Biometrics = measuring something physical and living about a person to prove who they are.
