What is the significance of the 8 in the route to the network It indicates that there are 8 hops between this router and the network. It represents the time in milliseconds it takes for a ping to reply when sent to the network. It indicates that there are 8 subnets in the destination network to which the router can forward packets. It indicates the number of consecutive bits from the left in the destination IP address of a packet that mi match to use that route. 3 so o o DCE so o o DTE R1 show controllers serial 0 0 Interface SerialO 3 Hardware is powerQUICC MPC860 32000 Coutput omitted R2 show controllers serial 0 0 Interface SerialOẮ Hardware is powerQUICC MPC860 DTE V .35 64000 output omitted Refer to the exhibit. Given the output in the exhibit how would a clock rate be determined for this link The rate would be negotiated by both routers. A rate would not be selected due to the DCE DTE connection mismatch. The rate configured on the DTE determines the clock rate. The rate configured on the DCE determines the clock rate. 4 A show ip .
