Question 115

After passively scanning the network of Department of Defense (DoD), you switch over to active scanning to identify live hosts on their network. DoD is a large organization and should respond to any number of scans. You start an ICMP ping sweep by sending an IP packet to the broadcast address. Only five hosts respond to your ICMP pings; definitely not the number of hosts you were expecting. Why did this ping sweep only produce a few responses?

    Correct Answer: C

    A switched network will not respond to packets sent to the broadcast address. In a switched network environment, switches only forward broadcast packets to specific ports rather than flooding all ports as a hub would. This prevents the broadcast packet from reaching all hosts on the network, resulting in fewer responses to an ICMP ping sweep.

Discussion
ManzerOption: C

A switched network will not respond to packets sent to the broadcast address. When a packet is sent to the broadcast address on a switched network, the switch will only forward the packet out to the ports that are connected to devices that have requested the broadcast packet, instead of flooding it to all ports like on a hub network. As a result, only a few hosts that requested the broadcast packet will respond, and not all hosts on the network.

4bd3116Option: C

In a switched network, switches do not forward broadcast packets to all ports. Instead, they only send them to the specific port where the destination host is located.

DumasOption: C

Switches reduce broadcast traffic C is correct
