• It is operating at 100Mbps

• It is operating in half-duplex mode

What is the loss of power as a signal travels through a component or system?

• Insertion loss

• Return loss

• Budget link loss

• Assertion loss

What tool is the quickest way to estimate where a flaw is in a 100m cable that looks fine from the outside?

• Toner probe

• Time-domain reflectometer

• Multimeter

• Loopback plug

Which of these is considered a balanced cable?
