  1. A security consultant is assessing a facility that stores high-value assets. Which perimeter security layer provides the FIRST line of defense?

    Answer: Outer perimeter fencing

    The outer perimeter fencing forms the first layer of defense in a defense-in-depth perimeter security model.

  2. Which access control model grants permissions based on the sensitivity label of a resource and the clearance level of the subject?

    Answer: Mandatory Access Control (MAC)

    Mandatory Access Control (MAC) uses sensitivity labels and clearance levels to enforce access decisions, commonly used in government and military systems.

  3. A 'mantrap' (airlock) entry system is PRIMARILY designed to prevent which security threat?

    Answer: Tailgating / piggybacking

    A mantrap prevents tailgating by ensuring only one person passes through a controlled entry at a time before the second door opens.

  4. When designing perimeter lighting for a secure facility, what is the recommended minimum foot-candle level for boundaries according to general security standards?

    Answer: 2 foot-candles

    Security standards generally recommend at least 2 foot-candles of illumination along perimeter boundaries to deter and detect intrusions.

  5. Which type of fence topping provides the GREATEST deterrence against climbing at a minimum cost?

    Answer: Razor wire coils

    Razor wire coils (concertina wire) provide greater deterrence than standard barbed wire because the razor edges inflict injury and are difficult to compress.

  6. In a biometric access control system, what does the term 'False Rejection Rate' (FRR) measure?

    Answer: The rate at which authorized users are denied access

    FRR (Type II error) measures how often a legitimate, enrolled user is incorrectly denied access by the biometric system.

  7. A security consultant recommends installing bollards at a building entrance. What is the PRIMARY security function of bollards?

    Answer: Preventing vehicle-borne attacks against a structure

    Bollards are designed to stop or deflect vehicles, protecting buildings and people from vehicle ramming attacks.
