Which of the following is the most likely reason why EMI from one wire does not affect the electrical behavior of another wire inside the same cable? b 7. Which of the following facts are in common between both of the Ethernet standards discussed in this chapter, 10BASE-T and 100BASE-T? (Choose two answers.) a,b 8.
In telecom closet 2, from the punch down block, to the switches, to the wall plates, and on to the offices workstation, plus one shared printer, cabling will change to Cat 5e UTP, using 1000 Base-T technology, achieving a throughput of 1000Mbps. A safety feature on Ethernet Lans, is its access method, CSMA/CD. CSMA/CD, means that your NIC checks the network to make sure it is not busy before transmitting, if two nodes do transmit at the same time having a collision, it will send out packets to inform other nodes of a data collision, then the NIC waits for the network to be inactive before retransmitting. On the
To identify where wireless devices such as APs should be placed in the network you should do what kind of test? Site Survey What does the WiFi Alliance do? Promotes Wi-Fi technology and certifies Wi-Fi products if they conform to certain standards. A company installs an 802.11g AP to rive its employee's wireless access from their cubicles. Carl's cubicle is 40 feet from the AP, Paul's is 20 feet, and Mark's is 100 feet.

Whichsecondary value will the routers use to determine the router ID? The highest IP address among the active interfaces will be used. 14. Refer to the exhibit. Routers R1 and R2 are directly connected via their serial interfaces and are both running the EIGRP routing protocol.
IP Address Class A, Class B, and Class C IP Address classes were the original organizational structure for IP addresses. The specific address class would determine the maximum potential size for a computer network. The address class would define which of the specific bits of the address would be used to identify the network and network identification, the bits to identify the host computer and host ID, and total number of host subnets permitted per network. Five total classes of IP addresses were defined, class A through E. Although the IP class term will commonly be used to describe the difference between one network and another, the practical use of addressing is not commonly used any more. It has been replaced with classless addressing where a netmask can be assigned to any IP address range.
This is a system that backs up an existing process with another process. With this system production time will not be lost because of equipment failure. This will initiate a backup machine in its place to run production. The general network too can be used to calculate the resulting reliability of redundant processes. Machine 1: (0.84) + {(0.84) x (1 - 0.84)} = (0.84) + {(0.84) x (0.16)} = (0.84) + (0.1344) = 0.9744.
Explain Packet-Switched Networks 7. Define scalability as it relates to networks. 8. Explain Quality of Service (QoS) and provide examples 9. Describe Network security and samples of possible intruders’ methods.
