Correct You've implemented a network where hosts are assigned specific roles, such as file sharing and printing roles. Other hosts access those resources, but they don't host services of their own. Which type of network do you have? Intranet Extranet Peer-to-peer Client-server Explanation
1/14/24, 3 : 47 PM Individual Response Page 2 of 11 about:srcdoc In a client-server network, hosts have specific roles. For example, some hosts are assigned server roles, which allow them to provide network resources to other hosts. Other hosts are assigned client roles, which allow them to consume network resources. In a peer-to-peer network, each host can provide network resources to other hosts or access resources located on other hosts, and each host is in charge of controlling access to those resources. An intranet is a private network that uses internet technologies. Services on an intranet are only available to hosts that are connected to the private network. An extranet is a private network that uses internet technologies, but whose resources are made available to external (but trusted) users. For example, you might create a website on a private network that only users from a partner company can access.

Correct Which of the following geographic network types is typically managed by a city as a public utility? Metropolitan area network (MAN) Personal area network (PAN) Wide area network (WAN) Local area network (LAN) Explanation A metropolitan area network (MAN) is a network that can cover an entire city.

1/14/24, 3 : 47 PM Individual Response Page 3 of 11 about:srcdoc A metropolitan area network (MAN) is a network that can cover an entire city. A city typically owns and manages a MAN as a public utility. A PAN is a small network for communication between personal devices. A LAN is contained to an office and managed by a business. A WAN is a collection of LANs that are connected together to form a large internetwork. WAN connections are typically managed by an ISP. References 2.1.4 Networking Facts q_intro_network_man_np6.question.fex Question 3. Correct You've implemented a network where each device provides all other devices on the network with access to shared files. Which type of network do you have? Multiple access Client-server Polling Peer-to-peer Explanation
1/14/24, 3 : 47 PM Individual Response Page 4 of 11 about:srcdoc In a peer-to-peer network, each host can provide network resources to other hosts or access resources located on other hosts, and each host is in charge of controlling access to those resources. In a client/server network, hosts have specific roles. For example, some hosts are assigned server roles, which allow them to provide network resources to other hosts. Other hosts are assigned client roles, which allow them to consume network resources. Polling is a media access method where a single device grants permission to other devices to access the network. Multiple access describes a media access method where each device determines when the medium is free. References 2.1.4 Networking Facts q_intro_network_peer_to_peer_np6.question.fex Question 4. Correct You have a network that uses a logical bus topology. How do messages travel through the network? Messages are sent directly to the correct destination device. Messages are sent to a central device that forwards them to the destination devices. Messages travel from one device to the next until they reach the destination device. Messages are broadcast to all devices connected to the network.
