    The major components of an access control system are ________.

    • A.

      A. electronic hardware, cables, access cards, power supply

    • B.

      B. controllers, cards, computer, software

    • C.

      C. card readers, locks, controllers, cables

    • D.

      D. door controllers, readers, cards, computer

    Correct Answer
    D. D. door controllers, readers, cards, computer
    Explanation
    An access control system typically consists of door controllers, readers, cards, and a computer. Door controllers are responsible for managing access to specific doors or entry points, readers are used to read access cards or credentials, cards are issued to authorized individuals for access, and a computer is used to manage and monitor the access control system. Therefore, option d is the correct answer as it includes all the major components of an access control system.

    An advantage of a magstripe format over a Wiegand format is:

    • A.

      A. Magstripe data can accommodate more unique card ID numbers.

    • B.

      B. Wiegard can be encrypted but a magstripe cannot.

    • C.

      C. Magstripes erase much more easily than Wiegands.

    • D.

      D. Magstripe is for a larger number of door controllers.

    Correct Answer
    A. A. Magstripe data can accommodate more unique card ID numbers.
    Explanation
    The advantage of a magstripe format over a Wiegand format is that magstripe data can accommodate more unique card ID numbers. This means that a magstripe format can support a larger number of cardholders or users compared to a Wiegand format.

    Rate this question:

  • 4. 

    The card ID number in a magstripe  ________.

    • A.

      A. is 26 decadecimal digits

    • B.

      B. is 14 hexadecimal digits

    • C.

      C. starts with and ends with zero.

    • D.

      D. is preceded by five zeros.

    Correct Answer
    B. B. is 14 hexadecimal digits
    Explanation
    The correct answer is b. The card ID number in a magstripe is 14 hexadecimal digits. Hexadecimal digits are a combination of numbers 0-9 and letters A-F, allowing for a larger range of possible values compared to decimal digits. A 14-digit ID number provides enough unique combinations to accommodate a large number of cards.

    Why are keypads less secure than card readers?

    • A.

      A. People forget their PIN numbers.

    • B.

      B. ID cards are easily duplicated.

    • C.

      C. PIN numbers are not difficult to obtain.

    • D.

      D. They can be used only on doors with an electric strike.

    Correct Answer
    C. C. PIN numbers are not difficult to obtain.
    Explanation
    Keypads are less secure than card readers because PIN numbers are not difficult to obtain. Unlike ID cards, which can be difficult to duplicate, PIN numbers can be easily guessed, stolen, or observed by someone nearby. This makes keypads more vulnerable to unauthorized access compared to card readers, which rely on physical possession of a unique ID card.

    Rate this question:

  • 7. 

    Fail safe locks are engaged when power fails

    • A.

      A. True

    • B.

      B. False

    Correct Answer
    B. B. False
    Explanation
    Fail safe locks are not engaged when power fails. In fact, fail safe locks are designed to disengage when power fails in order to ensure the safety of individuals. This allows people to exit a building or a room in case of an emergency, even if the power is out. Therefore, the correct answer is false.

    • C.

      C. Murphy’s Law

    • D.

      D. Kirchoff’s Law

    Correct Answer
    A. A. Ohm’s Law
    Explanation
    A – Ohm’s law shows the relationship between voltage, resistance and current

    Grommets or bushings are required only when running non-shielded cable through metal studs.

    • A.

      A. True

    • B.

      B. False

    Correct Answer
    B. B. False
    Explanation
    Grommets or bushings are required not only when running non-shielded cable through metal studs, but also when running any type of cable through metal studs. The purpose of grommets or bushings is to protect the cable from sharp edges and prevent damage to the insulation. Therefore, the statement that grommets or bushings are required only when running non-shielded cable through metal studs is false.

    Which of the following must be considered when selecting locking hardware for a door?

    • A.

      A. color of the existing door hardware

    • B.

      B. size and spacing of door hinges

    RS422/RS485 can be transmitted farther than RS232.

    • A.

      A. True

    • B.

      B. False

    Correct Answer
    A. A. True
    Explanation
    RS422/RS485 can be transmitted farther than RS232 because they use differential signaling, which means they transmit data using two wires instead of one. This allows for better noise immunity and longer transmission distances. RS232, on the other hand, uses single-ended signaling, which is more susceptible to noise and has shorter transmission distances. Therefore, the statement that RS422/RS485 can be transmitted farther than RS232 is true.

    Distributed processing means   ________.

    • A.

      A. decisions regarding access are made at the local controller

    • B.

    • D.

      D. both A & C

    Correct Answer
    D. D. both A & C
    Explanation
    Distributed processing refers to a system where decisions regarding access are made at the local controller, meaning that each individual controller has the authority to grant or deny access. Additionally, in a distributed processing system, even if there is a loss of communications between controllers, the system continues to allow access. Therefore, the correct answer is both A and C.
