expects only 4 percent network traffic growth in the next two years. Computers at each office are connected to 10/100 hubs. A router in New York provides connectivity to the Chicago office and to the Internet via a local ISP. The current routing protocol is RIP. The MPLS link is a T1 line and utilization usually hovers around 80 percent. The Ethernet segments currently run at an average 50 percent utilization; occasionally, network utilization will burst to 65 percent utilization. Users complain

routed throughout your network. Using a security service or protocol that either comes with your operating system, or IOS in a routers case, is easy to manage so that administrators can be alerted when unauthorized activity takes place throughout your domain. A good administrator will set “triggers”, which are activities that are tagged for alarm, to allow him or herself to be alerted when a breach occurs. These services use protocols such as TCP, UDP, ICMP and SNMP(v1-3). Also, many firewalls can

Lab 5.1 Connect the Internetwork Lab Review Questions 1. For what purpose is a transceiver used? A transceiver can be used for converting one type of Ethernet connector to another or by converting one type of I/O port to an Ethernet port. 2. This lab connects routers directly to each other via serial cables. Is this a typical configuration? No, By default, Cisco routers are DTE (Data Terminal Equipment)/ DCE (Data Circuit-Terminating Equipment) If not, to what equipment does the DCE end of the

Kyoto Protocol and Global Warming Evaluation xxxxxx ECO-370 April 21, 2014 Xiaobing Shuai Kyoto Protocol and Global Warming Evaluation Surface temperature of the earth has been an indicator of threatening critical concern. The principle of a greenhouse is that the enclosing glass or plastic allows the passage of incoming sunlight, but traps a portion of the reflected infrared radiation, which warms the interior of the greenhouse above the outside temperature (Field & Field, 2009, p. 430).
