What OSI physical layer term describes the capacity at which a medium can carry data?

bandwidth

Which port does Switch0 use to send frames to the host with the IPv4 address 10.1.1.5?

Fa0/11

What OSI physical layer term describes the physical medium that uses the propagation of light?

Fiber-optic cable

Case 5:

Integrates various physical technologies. Controls the NIC responsible for sending and receiving data on the physical medium.

What is the auto-MDIX feature?

It enables a device to automatically configure an interface to use a straight-through or a crossover cable.

What OSI physical layer term describes the amount of time, including delays, for data to travel from one point to another?

latency

What does the term "attenuation" mean in data communication?

loss of signal strength as distance increases

What OSI physical layer term describes the process by which one wave modifies another wave?

modulation

Case 4:

Integrates various physical technologies. Provides synchronization between source and target nodes.

What OSI physical layer term describes the measure of the transfer of bits across a medium over a given period of time?

throughput

What makes fiber preferable to copper cabling for interconnecting buildings? (Choose three.)

- limited susceptibility to EMI/RFI - greater distances per cable run - greater bandwidth potential

Which is a multicast MAC address?

01-00-5E-00-00-03

Refer to the exhibit. The PC is connected to the console port of the switch. All the other connections are made through FastEthernet links. Which types of UTP cables can be used to connect the devices?​

1 - rollover, 2 - straight-through, 3 - crossover

Which two functions are performed at the LLC sublayer of the OSI data link layer? (Choose two.)

1.) Enables IPv4 and IPv6 to utilize the same network interface and media. 2.) Places information in the frame that identifies which network layer protocol is being used for the frame.

Which two functions are performed at the MAC sublayer of the OSI data link layer? (Choose two.)

1.) Implements a trailer to detect transmission errors. 2.) Controls the NIC responsible for sending and receiving data on the physical medium.

Case 6:

Controls the NIC responsible for sending and receiving data on the physical medium Provides a mechanism to allow multiple devices to communicate over a shared medium.

Case 3:

Provides synchronization between source and target nodes. Implements a trailer to detect transmission errors.

Case 2:

Provides synchronization between source and target nodes. Integrates various physical technologies.

Refer to the exhibit. What is wrong with the displayed termination?

The untwisted length of each wire is too long.

What OSI physical layer term describes the physical medium for microwave transmissions?

air

What OSI physical layer term describes the physical medium which uses electrical pulses?

copper cable

What OSI physical layer term describes the measure of usable data transferred over a given period of time?

goodput

What is one advantage of using the cut-through switching method instead of the store-and-forward switching method?

has a lower latency appropriate for high-performance computing applications​
