A subscriber complains that his DSL rates are slower than the service he ordered. The customer ordered ADSL at 1 mpbs downstream and 256 kbps upstream, but the maximum bitrate observed during file downloads is
never more than 128 kbps downstream. Initial troubleshooting shows that the subscriber's DSL modem is trained at 1024 kbps downstream and 256 kbps upstream. Which one of the following presented choices is clearly the most appropriate information needed to begin troubleshooting the problem?

Host 1 and Host 2 are on Ethernet LANs in different buildings. A serial line is installed between two Cisco routers using Cisco HDLC serial line encapsulation. Routers A and B are configured to route IP traffic. Host 1
sends a packet to Host 2. A line hit on the serial line causes an error in the packet. When this is detected, the retransmission is sent by:
