Correct. Large businesses must design and monitor their computer networks because of their complexity. A network management application is a software tool that allows network administrators to troubleshoot and ensure optimal performance through network traffic data retrieval and analysis. Question 5 of 7 What is a benefit of packet switching? Packet switching cannot handle multi-media transmission, which can be expensive to send. Packet switching compiles all data to be transmitted in one packet. Packet switching does not need a dedicated network connection. Correct. Packet switching does not need a direct connection like a voice network to be established. Packets can be broken up, sent over the computer network, and reassembled at the destination. Question 6 of 7 Which of the following is not a circuit switching protocol? IP ATM Frame Relay Correct. Internet Protocol is not a circuit switching protocol, but a packet based protocol. Question 7 of 7 Why should businesses have a social media strategy? All business over the Internet comes from social media. Social media is an ubiquitous marketing channel. Social media is an e-commerce business platform. Correct. Social media is a marketing channel, in addition to the existing channels of print, TV, or radio, with a lot of potential customers.

The internet A telephone system A system of nodes and links Correct. A telecommunications network enables the exchange of information (sending and receiving) between end users across nodes and links. Question 2 of 7 What is the best description of how a packet switched network works? Data is digitized, enclosed in packets, and transmitted. Data is digitized and transmitted in fixed packet size and rates. Data is transmitted in a virtual circuit. Correct. Packet switched networks group data in packets and are transmitted in multiple simultaneous communication sessions. Question 3 of 7 What is the role of repeaters in telecommunication networks? Repeaters are used to send data to multiple devices in the network. Repeaters store transmitted data in case there is an error in transmission. Repeaters are used to amplify signals as they travel in a network. Correct. Repeaters receive and retransmit data at higher power so a transmission can go long distances. Question 4 of 7 How do small businesses and large enterprises protect themselves from network intrusions? Small businesses use detection intrusion operating systems, whereas large enterprises use firewalls. Both small and large enterprises use firewalls to prevent intrusion. Small businesses do not connect directly to the Internet, whereas large enterprises use core routers. Correct. Firewalls come in different sizes and prices. Large enterprises use powerful hardware and software tools, while small businesses use embedded software tools.

Open Switch Interpacket Open Standard International Open System Interconnection Correct. OSI stands for Open System Interconnection and is the foundation for data communication protocols. Question 6 of 7 What is a benefit of telecom services convergence for business? Combining voice, data, and video into one network reduces failures. Combining data, voice, and video into one platform means having only one network to service and maintain. Combining voice, data, and video into one platform reduces complexity. Correct. Deploying a converged telecom network means that only one network is used for all services, making maintenance easier. Question 7 of 7 What is the Internet of Things (IoT)? Internet of Things means every user in the world having access to the internet. Internet of Things means connectivity of all devices to enable service automation. Internet of Things means online e-commerce on every product and service. Correct. The term Internet of Things means that in the future, all devices, including appliances, cars, networks, systems, etc., will be connected to the Internet, which will facilitate servicing automation. Attempt 3 Question 1 of 7 What is the difference between a LAN and a WAN? A LAN consists of a client server network, whereas a WAN has client server and mainframe systems. A LAN connects computer systems locally, whereas a WAN connects systems over a long distance. A LAN is a large network, whereas a WAN is a small network.
