What statement accurately describes what a cable bend radius determines? A cable bend radius defines the twist rate of the cable inside of the insulation. A cable bend radius is the radius of the minimum arc into which you can loop the cable without impairing data. A cable bend radius determines the total number of bends that can exist in an overall cable before data is impaired. A cable bend radius is the radius of the maximum arc into which you can loop the cable without impairing data.
A cable bend radius is the radius of the maximum arc into which you can loop the cable without impairing data.
What statement correctly identifies the purpose of a software patch? 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 is a correction, improvement, or enhancement to software. 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.

TIA/EIA-568
What statement regarding main distribution frame or main distribution facilities is accurate? The MDF is the centralized point of interconnection for an organization's LAN or WAN. The MDF refers to the racks holding network equipment in an organization. The MDF provides an intermediate connection between the IDF and the end-user equipment on each floor. The MDF and entrance facility are always in separate rooms.
The MDF is the centralized point of interconnection for an organization's LAN or WAN.
What does backbone cabling consist of? The shielded cables that are used for high data transmission rates between an organization and an ISP. The cables or wireless links that provide interconnection between the entrance facility and MDF, and between the MDF and IDFs. It is cabling that connects workstations to the closest data room and to switches housed in the room. Short length cables with connectors at both ends.
