Data Communication Foundation Quiz-2282

What are the main characteristics to consider when choosing media for data transmission?

• Bandwidth, Security, Convenience, Cost

• Speed, Reliability, Flexibility, Size

• Color, Weight, Material, Length

• Voltage, Resistance, Current, Power

What are the wireless security threats associated with data communication?

• Fiber-Optic, Coaxial, Twisted-Pair, Ethernet

• Ease of Data Collection, Rogue Access Points, Jamming, Eavesdropping

• Attenuation, Crosstalk, EMI, RFI

• Packet Loss, Latency, Throughput, Jitter

How does a rogue access point work in a hijacking attack?

• It creates a secure connection to the network

• It uses a dedicated switch port for full-duplex communication

• It uses a point-to-point connection between devices

• It captures packets to get a valid MAC address

What are the benefits of deploying wireless communication?

• Increased interference, Decreased reliability, Increased susceptibility to eavesdropping, Decreased convenience

• Elimination of cabling costs, Elimination of access switch costs, Reduction in installation costs, Reduction in maintenance costs

• Decreased bandwidth, Increased latency, Increased packet loss, Decreased security

• Increased cabling costs, Reduced installation costs, Reduced maintenance costs, Increased access switch costs

What are the behaviors and characteristics of cabling to consider?

• Voltage, Resistance, Current, Power

• Attenuation, EMI, RFI, Eavesdropping

• Speed, Reliability, Flexibility, Size

• Color, Weight, Material, Length

What is the maximum length of 10Base5 (Thicknet) coaxial cable?

• 185 meters

• 500 meters

• 100 meters

• 300 meters

What is the purpose of twisting the pairs of wires in twisted-pair cable?

• To increase the cost of the cable

• To mitigate crosstalk

• To decrease the maximum cable length

• To increase susceptibility to EMI and RFI

What is the main advantage of full-duplex communication over half-duplex communication?

• Uses CSMA/CD to detect collisions

• No collisions on the point-to-point link

• Uses a dedicated switch port for each host

• Can send or receive, but not both at the same time

What are the benefits of using fiber-optic cable for data transmission?

• Increased interference, Decreased reliability, Increased susceptibility to eavesdropping

• No susceptibility to EMI or RFI, No susceptibility to eavesdropping, Longer cable runs

• Decreased bandwidth, Increased latency, Increased packet loss

• Susceptibility to EMI and RFI, Shorter cable runs, Lower cost

What are the common connector models for fiber-optic cable?

• BNC and N

• SFP and USB

• SC and LC

• ST and RJ-45
