CompTIA covers it in page 97 of the comptia A+ complete study guide.

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.

Optical fiber is the type of cable that should be used to terminate ST connectors on each end. ST connectors are commonly used for fiber optic cables, which transmit data using light pulses. Coaxial, shielded twisted pair, and HDMI are not types of cables that use ST connectors, but different types of connectors and transmission methods.

One possible reason why a remote user is unable to access files at home but can open the files at the office is that the offline file settings are not configured properly. Offline files are a feature of Windows that allows users to access files and folders that are stored on a network drive even when they are not connected to the network. Offline files are cached copies of the network files that are stored on the local computer and synchronized with the network files when the connection is restored.
To use offline files, the user needs to enable the feature on their computer and on the network drive that contains the files they want to access. The user also needs to make sure that the files and folders they want to access are available offline, which means they are marked for offline synchronization. The user can check and change these settings by following these steps:
* Open Control Panel and select Network and Internet > Sync Center > Manage offline files.
* In the Offline Files window, click Enable offline files if the feature is disabled, and then click OK.
* Restart the computer to apply the changes.
* Open File Explorer and navigate to the network drive that contains the files and folders the user wants to access.
* Right-click the files and folders and select Always available offline. A green sync icon will appear next to the items that are available offline.
* To manually sync the offline files with the network files, open Sync Center and click Sync All.
By doing this, the user should be able to access the files and folders on the network drive even when they are at home or away from the office. However, the user should also be aware of some limitations and risks of using offline files, such as:
* Offline files may not reflect the latest changes made by other users on the network, and may cause conflicts or errors when syncing.
* Offline files may take up a lot of disk space on the local computer, and may affect the performance or stability of the system.
* Offline files may be vulnerable to theft, loss, or damage if the local computer is not secured or backed up.
Therefore, the user should always backup their important files and folders, and use encryption or password protection to safeguard their offline files.
