    If during an ARP, a match does not occur, what does a router do to the packet?

    • Resends it

    • Reverts it

    • Encapsulates it

    • Discards it

    Correct Answer
    A. Discards it
    Explanation
    If during an ARP (Address Resolution Protocol) process, a match does not occur, a router will discard the packet. This means that the router will not forward the packet to its intended destination and will instead drop it. This could happen if the router is unable to find the appropriate MAC address for the IP address in the ARP table. By discarding the packet, the router ensures that it does not send the packet to an incorrect or unknown destination.

    Subnetting evolved when mainframes began to be replaced by pc’s.  In a subnet, what devices do NOT pass broadcast traffic in a network?

    • Routers

    • Switches

    • Servers

    • Hubs

    Correct Answer
    A. Routers
    Explanation
    Routers do not pass broadcast traffic in a network. Routers are used to connect different networks together and they operate at the network layer of the OSI model. When a broadcast message is sent within a network, routers do not forward it to other networks. Instead, they use routing tables to determine the best path for the message to reach its destination. This helps in reducing network congestion and improving network performance.
