    When you ping the loopback address, a packet is sent where?

    • On the network

    • Down through the layers of the IP architecture and then up the layers again

    • Across the wire

    • Through the loopback dongle

    Correct Answer
    A. Down through the layers of the IP architecture and then up the layers again
    Explanation
    When you ping the loopback address, a packet is sent down through the layers of the IP architecture and then up the layers again. This means that the packet is processed by each layer of the IP protocol stack, starting from the application layer and passing through the transport, network, and link layers. This allows the packet to be looped back within the same device, simulating communication with another device on the network.
