The company should buy Coaxial cables to be used with F-type connectors.

Explanation:
Primary Array:
Drag and drop two 120 GB SSD hard drives to the primary array bay.
Open the primary array and select RAID 1 as the RAID level. RAID 1 provides fault tolerance of one drive, ability to function with only one drive, easily recoverable data, high redundancy, and very fast on reads. It also does not need to be scalable and uses the minimum number of drives (two) for RAID 1.
Confirm the configuration and close the primary array.
Secondary Array:
Drag and drop two 300 GB SSD hard drives to the secondary array bay.
Open the secondary array and select RAID 0 as the RAID level. RAID 0 provides the best write performance and uses the minimum number of drives (two) for RAID 0. It also provides a total space of 600 GB (300 GB x
2), which meets the requirement.
Confirm the configuration and close the secondary array.
You have completed the configuration of the storage arrays.

If the filesystem check shows that all files are accessible and the filesystem is clean, but a hard drive error message persists, it's possible that the hard drive is experiencing S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) failure. This is a warning system built into hard drives to alert users of potential issues before they become critical.

When a laptop screen is not displaying on a conference room TV despite being connected to a wireless HDMI dongle, the issue is often related to the TV being set to the wrong input source. Since the in-room computer's desktop is displayed, it suggests the TV is currently set to the input source used by the in-room computer.
Changing the TV's input source to the one associated with the wireless HDMI dongle connected to the user's laptop is the simplest and most direct approach to resolve the issue. This does not involve adjusting network settings or hardware configurations but rather selecting the correct input source through the TV's input selection menu.
