A Fibre Channel SAN solution is a type of storage area network (SAN) that uses high-speed optical fiber cables to connect servers and storage devices. A SAN allows for hosting data without impacting performance when the data is accessed in real time by multiple users, as it provides fast data transfer rates, low latency, high availability, and scalability12. A local external hard drive (A) would not be suitable for multiple users, as it would limit the accessibility and security of the data. Adding extra memory to the server (B) would not solve the problem of data access performance, as it would not increase the bandwidth or reduce the congestion of the network. Compressing the data © would not improve the performance either, as it would add extraoverhead and complexity to the data processing and retrieval.

The administrator should use a subnet mask of 255.255.255.0 for this setup. A subnet mask is a binary number that defines how many bits of an IP address areused for the network portion and how many bits are used for the host portion. The network portion identifies the specific network that the IP address belongs to, while the host portion identifies the specific device within that network. The subnet mask is usually written in dotted decimal notation, where each octet represents eight bits of the binary number. A 1 in the binary number means that the corresponding bit in the IP address is part of the network portion, while a 0 means that it is part of the host portion. For example, a subnet mask of 255.255.255.0 means that the first 24 bits (three octets) of the IP address are used for the network portion and the last 8 bits (one octet) are used for the host portion. This subnet mask allows up to 254 hosts per network (2^8 - 2). In this case, the IP address of 10.20.10.15 and the default gateway of 10.20.10.254 belong to the same network of 10.20.10.0/24 (where /24 indicates the number of bits used for the network portion), which can be defined by using a subnet mask of 255.255.255.0.

Changing the boot order on the server and restricting console access would prevent unauthorized access attempts via USB devices at startup, as the server would not boot from any external media and only authorized users could access the console. Setting a BIOS/UEFI password on the server would also help, but it could be bypassed by resetting the CMOS battery or using a backdoor password. Configuring the host OS to deny login attempts via USB would not prevent booting from a malicious USB device that could compromise the system before the OS loads. Disabling all the USB ports on the server would limit functionality, as some peripherals or devices may need to use them. References:
