Explanation
A To accomplish the task, John has to supply power to the IP phones through an Ethernet cable. This method is also called as PoE (Power over Ethernet). It also became a standard (802.3af) in 2003. PoE (Power over Ethernet) is a method that is used to supply power to devices through an Ethernet cable. It centralizes the distribution of power. It also allows users to use a single uninterrupted power supply (UPS) instead of placing a UPS at the location of each device. Because of this, PoE eliminates the problem of using many cords for power distribution. Answer: C is incorrect. Placing the IP phones close to a UPS will not be the solution. This will be inconvenient for the users. Answer: D is incorrect. Installing a UPS with extra ports will not be the solution because it will not reduce the usage of power cords. Answer: B is incorrect. Installing an extension board will not be the solution because it will not provide uninterrupted power supply.
