39 Ralph is designing the HVAC implementation for his company's new central datacenter, which will house all of the equipment for the corporate headquarters and the company's manufacturing facility. The datacenter must adhere to the Tier III standard defined by the Uptime Institute, which calls for at least 99.9 percent uptime. As part of the environmental infrastructure for the datacenter, Ralph plans to install sensors to monitor environmental factors that can affect computer equipment and generate alerts when conditions exceed accepted thresholds. Which of the following environmental factors is not one of those that Ralph should arrange to monitor to protect the equipment specific to a datacenter?FloodHumidityRadonStatic electricityTemperature

44 The cable plant for your company network was installed several years ago by an outside contractor. Now, some of the paper labels have fallen off your patch panels, and you do not know which wall plate is connected to each port. Assuming that you are working on a properly maintained and documented network installation, which of the following is the easiest way to determine which port is connected to which wall plate?Consult the cable diagram provided by the cabling contractor at the time of the installation.Call the cable installation contractor and see if he or she can remember which ports go with which wall plates.Attach a tone generator to a patch panel port and then test each wall plate with a locator until you find the correct one. Repeat this for each port that needs labeling.Use a cable certifier to locate the patch panel port associated with each wall plate port.
