In this scenario, running a network cable over a long distance (279ft or 85m) and sharing conduit with a large power cable requires careful consideration of electromagnetic interference (EMI) and the physical distance limitations of the cable type. Fiber optic cables are immune to electromagnetic interference and can support much longer distances than copper-based cables like Cat 5e or Cat 6 without signal degradation. This makes fiber optic the most appropriate choice for this project.

After setting up a RAID 5 array, the next step is to make the storage space usable by the operating system. This involves partitioning the array to define how the storage space is organized and then formatting it with a file system that the operating system can understand, thus making it possible to copy files to the array. Decreasing the number of drives, rebuilding the array, or checking the hot spare status would not address the issue of the array not being ready to store files.

White lines running through text and graphics in printouts from an inkjet printer are commonly caused by clogged printheads. When the printhead nozzles are clogged, they cannot deliver ink properly to the paper, resulting in white lines where ink should have been deposited. Worn-out rollers, faulty ink cartridges, and poor-quality paper can cause other printing issues but are less likely to cause white lines in the printed output.

When replacing a power supply in a computer, wearing an antistatic wrist strap is crucial to prevent static electricity from damaging the computer components. Static electricity can easily damage sensitive electronic components within the computer; therefore, using an antistatic wrist strap helps to ground the technician, mitigating the risk of electrostatic discharge. The other options provide general safety but do not address the primary concern of electrostatic discharge in this context.
