For (71) service, we need a virtual-circuit subnet. Let us see how that works. The idea behind virtual circuits is to avoid having to choose a new (72) for every packet sent. Instead, when a connection is established, a route from the (73)machine to the destination machine is chosen as part of the connection setup and stored in tables inside the (74) That route is used for all traffic flowing over the connection, exactly the same way that the telephone system works. When the connection is released, the virtual circuit is also terminated. With connection-oriented service, each packet carries an (75) telling which virtual circuit it belongs to.A．connectionlessB．connection-orientedC．datagramD．telegram

Refer to the exhibit. A Boston company bought the asse ts of a New York company and is trying to route traffic between the two data networks using EIGRP over EoMPLS. As a network consultant, you were asked to verify the interoperability of the two networks. From the show ip route command output, what can yo u tell the customer about the traffic flow between the subnet in New York (172.16.8.0/24) and the subnets in Boston (172.16.16.0/24 and 10.10.16.0/24)?（）A. Traffic is flowing between the 172.16.8.0 subnet and subnets 172.16.16.0 and 10.10.16.0 and no configuration changes are needed.B. Auto - summary must be disabled on N1 and B1 before traffic can flow between the 172.16.8.0 subnet and subnets 172.16.16.0 and 10.10.16.0.C. Traffic will flow between the 172.16.8.0 subnet and 172.16.16.0 without any further configuration changes. However, auto - summary must be disabled on N1 and B1 before traffic can flow between the 172.16.8.0 subnet and the 10.10.16.0 subnet.D. Auto - summary must be disabled on N1 and B1 before traffic can flow between the 172.16 .8.0 subnet and the 172.16.16.0 subnet. However, traffic will flow between the 172.16.8.0 subnet and 10.10.16.0 without any further configuration changes.

多选题You run a 16-bit scientific data analysis package on your Windows 2000 Professional computer. The package consists of three components. The first component is a data acquisition application that monitors continuous data output from scientific instruments. The second component is a data analysis application that receives data from the data acquisition application by using shared memory. The third component is a data graphing application that displays the processed data in real time. The data analysis application communicates with the data graphing application by using OLE. When you attempt to analyze large data sets, your computer is not able to display data in real time. You install a second processor in your computer; only one processor is used while the package is running, even though task manager shows both processors. You want your data analysis package to use both processors. What should you do?（）AConfigure the data acquisition application to run in its own virtual DOS machine (VDM).BConfigure the data analysis application to run in its own virtual DOS machine (VDM).CConfigure the data graphing application to run in its own virtual DOS machine (VDM).DConfigure the virtual DOS machine for the data acquisition and data analysis applications to.have a hard affinity for processor 0.
