B and C How do a router and switch differ when handling a message? - The switch will purposefully drop messages if message traffic exceeds its capacity. - Both a router and a switch use the message's destination address to select the line to route the incoming message to. - There is no difference in how a router and a switch handle messages. - The router will purposefully drop messages if message traffic exceeds its capacity. - The router will purposefully drop messages if message traffic exceeds its capacity. In a client-server network, what is the role of the server? - The role of the server is to take requests from the client and send back the requested information. - The role of the server is the same as the role of the client because all of the computers on this type of network are equal. - The role of the server is to send out requests for information. - The role of the server is to maintain connections to remote servers. - The role of the server is to take requests from the client and send back the requested information. How do virtual machines support a business computing ecosystem? - A virtual machine (VM) is a server that users can log into and use different OSs and applications associated with the different OSs. - A virtual machine (VM) is a broadcasting device that facilitates communication across a network, thus supporting a business computing ecosystem. - A virtual machine (VM) is made available by software and permits a computer to run multiple OSs. In a business ecosystem, this allows for improved collaboration that is not restricted by platform software. - A virtual machine (VM) is a whole separate physical computer that provides users access to an OS different from their primary computer. Being able to have access to a computer with a different OS facilitates collaboration in the business ecosystem. - A virtual machine (VM) is made available by software and permits a computer to run multiple OSs. In a business ecosystem, this allows for improved collaboration that is not restricted by platform software. Which of the following servers responds to HTTP requests on the Internet? - FTP server - Print server - File server - Web server - Web server Which of the following servers monitors requests, but doesn't send files in return? - FTP server - File server - Web server - Print server - Print server Which of the following servers can generate reports from client queries? - Mail server - Database server - Web server - File server - Database server
Which of the following best describes the benefits of a star network topology? - In a star network, every device has a point-to-point connection with every other device in the network. This allows any device to communicate with any other device. - It is easy to add (or remove) devices on a star network and maintain the efficiency of message transferal. - A star network requires a dedicated device (server, hub, or switch) which makes communication more efficient. - All devices in a star network have a single point-to-point connection with the neighboring computers in the network. - It is easy to add (or remove) devices on a star network and maintain the efficiency of message transferal.
