    IP is connectionless and will occasionally drop a packet en route to a destination IP address. If packets are dropped, how will messages be completed?
    • A. 

      Only the IP portion of the packet is dropped, but the TCP portion continues to the last router.

    • B. 

      The routing protocols will carry the TCP information to the previous-hop router, which sends a reverse notification to the source.

    • C. 

      The routing protocols, such as RIP, are connection oriented and will contact the source host.

    • D. 

      The destination host is expecting the packet and will send a request if it does not arrive.

    • E. 

      The IP header contains the source address so that the packet can be returned by the router that receives the packet when the TTL is 0.
