Which type of Ethernet cable should be used to directly connect two devices that both use the same pins for transmitting and receiving data?
crossover twisted-pair cable
A type of interference that occurs when cables are bundled together for long lengths is known as:
crosstalk
Which term describes the interference when electrical impulses from one cable cross over to an adjacent cable?
crosstalk
Connecting a unlike-devices, such as a computers to an Ethernet switch, requires what type of UTP Ethernet cable?
straight-through
Refer to the exhibit. One end of the cable is terminated as displayed, and the other end is terminated in accordance with the T568A standard. What type of cable would be created in this manner?
straight-through
A network administrator would like to determine the path a packet takes to reach the destination 192.168.1.1. What is the best command to determine the network path?
tracert 192.168.1.1
Which is the most common type of wired media to connect end devices to an Ethernet LAN?

Directly connecting like-devices, such as two computers, requires what type of UTP Ethernet cable?
crossover
A network specialist has been hired to install a network in a company that assembles airplane engines. Because of the nature of the business, the area is highly affected by electromagnetic interference. Which type of network media should be recommended so that the data communication will not be affected by EMI?
fiber optic
Which type of network cable is commonly used in backbone networks and telephone companies?
fiber optic
Which type of cabling is immune to RFI and EFI?
fiber-optic
Which type of wired media is used to carry digital information at very high speeds over long distances?
fiber-optic cable
Which of the following is an advantage of coaxial cable compared to UTP?
improved data carrying characteristics
Which command can be used to verify connectivity between two host devices?
ping
What is a purpose of an IP address?
It identifies the source and destination of data packets on a network.
A group of newly hired entry-level network engineers are talking about the network cabling they are going to have to install as a team. What is a characteristic of Ethernet straight-through UTP cable?
It is susceptible to interferences from EMI and RFI.
