The first line of physical defense is perimeter security, which comes from the following:
* Fencing
* Bollard posts to protect buildings from vehicle incursion
* Lighting
* Locked gates
* Security guards
* Guard dogs
* Limited access to areas of a facility
* Motion-sensing security systems

This is the most likely misconfigured setting because the default gateway is the router that connects the local network to other networks. If the default gateway is incorrect, the server will not be able to communicate with remote users or devices outside its own subnet. References: https://docs.microsoft.com/en-us/windows-server

The RAID level that provides the highest possible capacity for a storage array is RAID 0. RAID 0 is a type of RAID level that provides performance enhancement by using striping. Striping means dividing data into blocks and distributing them across multiple disks to increase speed and capacity. RAID 0 does not provide any fault tolerance or redundancy, as it does not use any parity or mirroring techniques. RAID 0 uses all of the available disk space for data storage, without losing any space for overhead. Therefore, RAID 0 provides the highest possible capacity for a storage array, but also has the highest risk of data loss.

Server lifts should only be used on level floors strong enough to support lift and load... Using a lift may be slower than maneuvering by hand; but if worker or equipment safety (usually because of weight) is a factor; using a lift is required.
