C724-M8-WIRELESS TECHNOLOGY AND BUSINESS Quiz.docxC724-M8-WIRELESS TECHNOLOGY AND BUSINESS Question 1 of 6 Which of the following best describes the first generation of mobile networks? 1G networks... were “voice only” analog communication networks. 1G networks were “data digital” networks. 1G networks were “optical data” networks. Correct. 1G networks were not digital; they were analog. Question 2 of 6 [True/False] Spoofing a network is a false representation of digital identity and leads to less packet encapsulation information as the network responds. True False Correct. Spoofing leads to a network response, which causes further identification of network access information. Question 3 of 6 What is a key trend in mobile communications that businesses must be aware of? Mobile networks will replace wired networks. Mobile access to the Internet is growing exponentially. Mobile communications is faltering because of lack of security. Correct. Businesses must be aware that Internet access via mobile, smart devices is growing exponentially and has surpassed desktop Internet access. Question 4 of 6 [True/False] When installing a wireless LAN, the access points must be configured to TCP/IP and 4G protocols. True False Correct. Access points are configured to TCP/IP protocol. Most wireless LANs are based on IEEE 802.11 standards and use the IP address scheme. Question 5 of 6 What is meant by wireless networks being scalable?

Scalability refers to the ability to expand range built into the infrastructure. Scalability refers to the ability to grow user base and data services with ease, built into the infrastructure. Correct. Wireless networks are easier to scale, handle a new, larger user base, service a growing access base, and handle capacity for new data services, such as multimedia. Question 6 of 6 What is the advantage of RFID passive tags? Passive tags use battery power. Passive tags emit or reflect optical signals. Passive tags leverage energy from radio signals. Correct. Passive tags are small and inexpensive because they have no internal power source. Attempt 2 Question 1 of 6 What is the difference between a hertz and a byte? A byte is a unit of digital information, whereas a hertz is the standard measurement of frequency. A byte is a measure of frequency, whereas a hertz is a wavelength. A byte is a data transmission speed, whereas a hertz is a frequency. Correct. A byte is a unit of data, whereas a hertz is a measurement of frequency. Question 2 of 6 Which of the following statements is false? Security and hacking is the main disadvantage to wireless communication. An advantage to wireless communication is that information is available from anywhere, but the main disadvantage is that networks cannot easily be reconfigured because there is no physical wiring.

Correct. Security and hacking is the main disadvantage to wireless communication. Question 3 of 6 In the near future, most devices, such as home appliances, automobiles, and consumer product packages, will be connected to the Internet. What is this field of networking called? 5G IoT WAN Correct. The Internet of Things (IoT) will embed electronic sensors and connectivity in all devices so they can communicate via the Internet. Question 4 of 6 "Fill in the blank" question: select the correct answer.Wireless LAN networks support the on-premise workforce, making them more mobile, which increases productivity and access to real-time information. Correct. When staff have mobility, they can access information anytime, thereby increasing productivity. Question 5 of 6 "Fill in the blank" question: select the correct answer.Wired networks may not be advantageous because of the large amount of cables involved, but they provide businesses with network reliability and security. Correct. Wired networks are inherently more secure because signals cannot be sniffed without physical penetration of premise. Question 6 of 6 Which of the following best describes wireless sensor networks (WSNs)? WSNs are antenna mesh. WSNs are spatially distributed sensors. WSNs are highly powered access points. Correct. WSNs are networks composed of sensors located in strategic locations to monitor specified conditions and emit wireless signals with a specific information. productivity security This study source was downloaded by 100000824449084 from CourseHero.com on 04-27-2021 08:18:48 GMT -05:00 https://www.coursehero.com/file/67325863/C724-M8-WIRELESS-TECHNOLOGY-AND-BUSINESS-Quizdocx/ This study resource was shared via CourseHero.com C724-M8-WIRELESS TECHNOLOGY AND BUSINESS Attempt 3 Question 1 of 6 [True/False] 4G networks, also called Long-Term Evolution (LTE), offer data transmission speeds of 64 kbps in the Ultra High Frequency band. True False Correct. 4G networks, also called Long-Term Evolution (LTE), offer data transmission speeds of 5 to 12 Mbps in the Ultra High Frequency band. Question 2 of 6 What is the most prevalent hacker attack on wireless networks? Sniffing Spoofing Probing Correct. In wireless networks, sniffing is most common because signals travel through the air. Question 3 of 6 "Fill in the blank" question: select the correct answer.Internet access via mobile devices is growing exponentially, surpassing Internet access by fixed, desktop computers. Correct. Mobile smart devices are surpassing desktops for Internet access. Question 4 of 6 What are three reasons that more businesses are deploying wireless networks? Security, mobility, and cost Mobility, cost, and scalability Multimedia, flexibility, and cost Correct. More businesses are deploying wireless networks to increase productivity by having mobile users access information from anywhere. They are less costly to maintain, and are more scalable than wired networks. Question 5 of 6 What are three risks to wireless networks? Sniffing, spoofing, and probing mobile This study source was downloaded by 100000824449084 from CourseHero.com on 04-27-2021 08:18:48 GMT -05:00 https://www.coursehero.com/file/67325863/C724-M8-WIRELESS-TECHNOLOGY-AND-BUSINESS-Quizdocx/ This study resource was shared via CourseHero.com C724-M8-WIRELESS TECHNOLOGY AND BUSINESS Denial of service, security, and sniffing Sniffing, denial of service, and unauthorized access Correct. Wireless networks are more susceptible to sniffing, spoofing, and probing. Question 6 of 6 "Fill in the blank" question: select the correct answer.
