    question: Which statement correctly describes a difference between macvlan and bridge network drivers?
    answers:
      - { value: 'Bridge networks assign unique MAC addresses to containers while macvlan does not', correct: false }
      - { value: 'Macvlan containers communicate through the Docker bridge interface just like bridge networks', correct: false }
      - { value: 'Macvlan containers are directly reachable on the physical network without NAT, whereas bridge containers use NAT for external access', correct: true }
      - { value: 'Bridge networks require promiscuous mode on the host NIC but macvlan does not', correct: false }

    question: What is a known limitation when using the macvlan network driver in Docker?
    answers:
      - { value: 'Containers on a macvlan network cannot communicate with external networks', correct: false }
      - { value: 'The Docker host itself cannot directly communicate with its own macvlan containers without additional configuration', correct: true }
      - { value: 'Macvlan networks do not support IPv4 addressing', correct: false }
      - { value: 'Only one container can be attached to a macvlan network at a time', correct: false }
