Question 1: which best describes where an RJ45 cable would likely be used?

Voice over IP connection Fax machine connection Telephone connection Modem connection

Answer:

Voice over IP connection RJ45 ports are used to create Ethernet networks by connecting multiple computers and networking devices. RJ45 ports have eight connector pins. Voice over IP (VoIP).Question 2: have computer with an onboard LAN adapter, which has failed, you are unable to connect the computer to the network. What should you do?Replace motherboard.Add network card using a PCI slot.Clear CMOS settings.Add network card using an AGP slot.

Answer:

Add a network card using a PCI slot. computer would then use the new network adapter instead of the one integrated on the motherboard. While installing the new card, you should disable the onboard LAN adapter to prevent it from showing in Device Manager.

Question 3: The ______ ________connects network devices to the network with a single patch cable, and the failure of a patch cable will make the connected device unavailable.

Answer:

star topology

Question 4: A protocol used to assign IP addresses to hosts.

Answer:

DHCP

Question 5: accurately describes how a modem works?

Answer:

Modem is shorthand for modulator/demodulator. job is to convert (or modulate) digital data from PC to analog phone signals & transmit through phone network. also receives analog data from phone network & converts (or demodulates) into digital PC data.

Question 6: _____ is a network in a small geographic area, like in an office

Answer:

LAN Question 7: Which of the following protocols carry phone calls over an IP-based network?VoIP TCP RTSP HTTP

Answer:

VoIP is a method for carrying phone calls over IP-based network. TCP is a protocol which guarantees that data arrives at a destination without errors. VoIP is usually implemented on top of UDP instead of TCP to reduce latency.Question 8: A _____ is the interconnection of components, such as laptops, mobile devices, printers, mice, keyboards, and other Bluetooth equipped devices, using some form of wireless technology within a personal range (typically 10 meters or less).

Answer:

PAN (personal area network)

Question 9: A customer is upgrading the routers and switches in their network. The signal source in these network devices is a light-pulse. Which of the following network cabling options is MOST likely being used in this upgrade? Fiber optic, Twisted pair, Copper, Wi

Answer:

Fiber Optic The signal source used with Fiber optic cables is a light pulses. Fiber optic cabling can be a laser, but most often, it is an LED Question 10: Which of the following hardware devices regenerates a signal out all connected ports without examining the frame or packet contents?Hub Bridge Router Gateway Switch

Answer:

Hub A hub and a repeater send received signals out all other ports. These devices do not examine the frame or the packet contents. A switch or a bridge use the MAC address in a frame for forwarding decisions. A router uses the IP address in a packet for

Question 11: What device is used to create a physical star topology?

Router, Repeater, Switch, or Bridge

Answer:

A physical star topology uses a switch or a hub. Routers are used to connect multiple subnets together.A repeater regenerates a network signal so that it can be transmitted for longer distances.Question 12: How do switches and bridges learn where devices are located on a network?

Answer:

When a frame enters a port, the source MAC address is copied from the frame header.Question 13: Which of the following LAN devices receives a signal on one port and forwards that signal only to the port where the destination device is connected?Route Hub Network adapter Switch

Answer:

Switch

A switch offers guaranteed bandwidth to each port, unlike a hub, which shares bandwidth among all the network ports Question 14: Which network component connects a device to the transmission media and allows it to send and receive messages?Switch Protocol Bridge Network interface card

Answer:

The network interface card (NIC) allows a device to send and receive messages over the transmission media.

Question 15: An 8-port switch receives a frame on port number

• The frame is addressed to an unknown device. What will the switch do?

Send the frame out the destination port.Drop the frame.Send the frame out all 8 ports.Send the frame out ports 2-8.

Answer:

Send the frame out ports 2-8. it will send the frame out all ports except for the port on which the frame was received. After the switch learns the port that is used to reach the destination device, it will send the frame out only that port.

Question 16: Which of the following is a valid MAC address?

192.168.12.15

34-9A-86-1G-B3-24

C0-34-FF-15-01-8E

255.255.255.0

Answer:

C0-34-FF-15-01-8E

MAC address is unique identifier hard coded on network adapter card. it has a total of 12 hexadecimal number. Note an answer would be valid MAC address except it uses a G value, which is beyond the range of a hexadecimal number.Question 17: You have implemented an ad hoc wireless network that doesn't employ a wireless access point. Every network card can communicate directly with others on the network. What type of physical network topology has been implemented in this type of network?

Answer:

mesh. There's no central connecting point. Any host can communicate directly with any other host on the network. impractical on a wired network. However, a mesh topology can be implemented with
