Two routers are connected via their serial ports in a lab environment. The routers are configured with valid IP addresses‚ but they cannot ping each other. The show interface serial0/0 command shows that the serial0/0 interface is up but the line protocol is down. What could be the cause of this problem? The no shutdown command has not been applied to the interfaces. *The clock rate command has not been entered on the DCE interface. The interface timers are not cleared. The FastEthernet interface

Wide area network is a kind of cross region data communication network using the equipment provided by telecommunications operators as the information transmission platform. Refering to the OSI reference model‚ WAN technologies are mainly located in the bottom three levels. respectively is the physical layer‚ data link layer and network layer (Groth & Skandler‚ 2009). There are three typical types of wide area network. The first one is Public

Which three statements characterize the transport layer protocols? (Choose three.) X TCP and UDP port numbers are used by application layer protocols. TCP uses port numbers to provide reliable transportation of IP packets. UDP uses windowing and acknowledgments for reliable transfer of data. X TCP uses windowing and sequencing to provide reliable transfer of data. X TCP is a connection-oriented protocol. UDP is a connectionless protocol. 6 Which type of media is immune to EMI and RFI?

Wireless communication protocols have evolved rapidly since the introduction of 802.11 Legacy over a decade ago. Over the last 10 years we have seen efficiency and performance increases on all fronts‚ which have lead to greater range and faster transfer speeds. With Legacy 802.11 protocols‚ speeds maxed out at around 2 Mbits/sec and indoor range was only about 20 meters. In 1999‚ the 802.11 protocol got a couple of amendments in the form of 802.11a and 802.11b. Both offered higher speeds and slightly
