What statement accurately describes what a cable bend radius determines? Correct! 1 A cable bend radius is the radius of the maximum arc into which you can loop the cable without impairing data 2 A cable bend radius is the radius of the minimum arc into which you can loop the cable without impairing data. 3 A cable bend radius determines the total number of bends that can exist in an overall cable before data is impaired. 4 A cable bend radius defines the twist rate of the cable inside of the insulation.

True

Copper-based cable transmits data via electric signals, and fiber-optic cable transmits data via pulsing light sent from a laser or light-emitting diode (LED)

True

What statement correctly identifies the purpose of a software patch? A software patch is a correction, improvement, or enhancement to software. A software patch is a major change to a software package that enhances the functionality and features of the software, while also correcting bugs and vulnerabilities. A software patch involves the process of reverting to a previous version of software after attempting to upgrade it. A software patch is a container for new software, and must be installed on relevant devices and incorporated with network resources.

A software patch is a correction, improvement, or enhancement to software.
