The connectivity between these two hosts allows for videoconferencing calls.There is connectivity between this device and the device at 192.168.100.1.On the basis of the output, which two statements about network connectivity are correct? (Choose two.) Which three addresses are valid public addresses? (Choose three.)Ĥ4. IPv6 multicast addresses have the prefix FF00::/8.Ĥ3. FDEE::/7 is a unique local address because it is in the range of FC00::/7 to FDFF::/7. The original IPv6 specification defined site-local addresses and used the prefix range FEC0::/10, but these addresses were deprecated by the IETF in favor of unique local addresses. Link-local addresses are in the range of FE80::/10 to FEBF::/10. Which three factors could influence the differences in throughput? (Choose three.) The administrator notices that the network throughput appears lower than the bandwidth expected. A network administrator is measuring the transfer of bits across the company backbone for a mission critical financial application. A crossover cable is used to interconnect similar devices together, for example, between two switches, two routers, and two hosts.ġ8. A straight-through (also called patch) cable is usually used to interconnect a host to a switch and a switch to a router. the reliability of the gigabit Ethernet infrastructure of the backboneĪ rollover cable is a Cisco proprietary cable used to connect to a router or switch console port.the bandwidth of the WAN connection to the Internet.the latency that is created by the number of network devices that the data is crossing.the type of traffic that is crossing the network.the sophistication of the encapsulation method applied to the data.the amount of traffic that is currently crossing the network.The engineer notices that the network throughput appears lower than the bandwidth expected. A network engineer is measuring the transfer of bits across the company backbone for a mission critical database application. The PDUs are named according to the protocols of the TCP/IP suite:ĭata – The general term for the PDU used at the application layer.īits – A physical layer PDU used when physically transmitting data over the mediumġ5. At each stage of the process, a PDU (protocol data unit) has a different name to reflect its new functions. During the process, various protocols add information to it at each level. It provides the intrusion protection services for the device.Īpplication data is passed down the protocol stack on its way to be transmitted across the network media.It provides dedicated firewall services.It interfaces between the users and the kernel.What is the function of the shell in an OS? Powerline networking is a trend for home networking that uses existing electrical wiring to connect devices to the network wherever there is an electrical outlet, saving the cost of installing data cables.Ĥ. Smart home technology is integrated into every-day appliances allowing them to interconnect with other devices, making them more ‘smart’ or automated. BYOD is about end users having the freedom to use personal tools to access information and communicate across a business or campus network. These services are available on-demand and delivered economically to any device anywhere in the world without compromising security or function. financial transactions, web page, audio conferenceĬloud computing extends IT’s capabilities without requiring investment in new infrastructure, training new personnel, or licensing new software.audio conference, web page, financial transactions.audio conference, financial transactions, web page.financial transactions, audio conference, web page. If QoS is implemented on this network, what will be the priorities from highest to lowest of the different data types? The third employee participates in an important live audio conference with other corporate managers in branch offices. The second employee accesses the corporate database to perform some financial transactions. The first employee uses a web browser to view a company web page in order to read some announcements. Three bank employees are using the corporate network. Quality of service (QoS) is a mechanism for managing congestion and ensuring reliable delivery of content to all users.Ģ. These networks depend on multiple or redundant paths between the source and destination of a message.Ī scalable network can expand quickly to support new users and applications without impacting the performance of the service being delivered to existing users. Fault tolerant networks limit the impact of a failure because the networks are built in a way that allows for quick recovery when such a failure occurs.
