Business Impact Analysis (BIA) is the process that determines the potential impacts of business function disruptions and gathers information needed to develop recovery strategies. A critical part of BIA is examining Recovery Point Objectives (RPOs) and Recovery Time Objectives (RTOs) for a disaster recovery strategy. RPOs define the maximum age of files that must be recovered from backup storage for normal operations to resume after a disaster, while RTOs specify the maximum amount of time that a resource can remain unavailable after a disaster.

Category 3 type of UTP cable uses four pairs of twisted cable and provides transmission speeds of up to 16
Mbps. They are commonly used in Ethernet networks that operate at the speed of 10 Mbps. A higher speed is
also possible by these cables implementing the Fast Ethernet (100Base-T4) specifications. This cable is used
mainly for telephone systems.
Answer option C is incorrect. This category of UTP cable is the most commonly used cable in present day
networks. It consists of four twisted pairs and is used in those Ethernet networks that run at the speed of 100
Mbps. Category 5 cable can also provide a higher speed of up to 1000 Mbps.
Answer option A is incorrect. It is also known as Category 5 Enhanced cable. Its specification is the same as
category 5, but it has some enhanced features and is used in Ethernets that run at the speed of 1000 Mbps.
Answer option D is incorrect. This category of UTP cable is designed to support high-speed networks that run
at the speed of 1000 Mbps. It consists of four pairs of wire and uses all of them for data transmission. Category
6 provides more than twice the speed of Category 5e, but is also more expensive.
