TCP OS fingerprinting attempts can be identified by analyzing various TCP/IP stack behaviors, one of which is the TCP Maximum Segment Size (MSS). The MSS value indicates the size of the largest segment of TCP data that a device is willing to receive. Different operating systems have different default MSS values, and a value less than 1460 can suggest an OS fingerprinting attempt, as it may indicate that the sender is trying to avoid fragmentation or is probing to discover the OS based on MSS response.
References: The use of Wireshark to monitor and analyze network traffic, including identifying TCP OS fingerprinting attempts, is covered in the EC-Council's Certified Network Defender (CND) course. The course materials would include detailed explanations on how to use Wireshark filters to detect such activities, and the reference to MSS values is consistent with standard network analysis practices for identifying OS fingerprinting attempts.

SRAM, or Static Random-Access Memory, is known for its low access time, typically around 20 ns, which makes it suitable for applications requiring high speed, such as cache memory in computers or, in this case, a RAID system. SRAM is faster than DRAM because it does not need to be refreshed as often, which is why it's used where speed is critical. Although SRAM is more expensive and has less density compared to other types of RAM, its speed advantage makes it the preferred choice for Brendan's RAID system requirements.

The Network News Transfer Protocol (NNTP) is an Internet application protocol used for transporting Usenet news articles (netnews) between news servers and for reading and posting articles by end user client applications. NNTP is designed so that news articles are stored in a central database, allowing the subscriber to select only those items that he wants to read. Answer option D is incorrect. Network Time Protocol (NTP) is used to synchronize the timekeeping among the number of distributed time servers and clients. It is used for the time management in a large and diverse network that contains many interfaces. In this protocol, servers define the time, and clients have to be synchronized with the defined time. These clients can choose the most reliable source of time defined from the several NTP servers for their information transmission. Answer option C is incorrect. The Data Link Switching Client Access Protocol (DCAP) is an application layer protocol that is used between workstations and routers for transporting SNA/NetBIOS traffic over TCP sessions. It was introduced in order to address a few deficiencies by the Data Link Switching Protocol (DLSw). The DLSw raises the important issues of scalability and efficiency, and since DLSw is a switch-to-switch protocol, it is not efficient when implemented on workstations. DCAP was introduced in order to address these issues. Answer option B is incorrect. The BOOTP protocol is used by diskless workstations to collect configuration information from a network server. It is also used to acquire a boot image from the server.

The Path rule is used to specify a path to a folder or application and control access based on that path. By setting a Path rule, an administrator can disallow a system or user from accessing all applications except for those located in a specified folder. This is particularly useful for creating a secure environment where users can only run applications from a trusted location, thereby preventing the execution of unauthorized or potentially harmful programs.

Encrypting confidential data stored on the server and performing regular backup will not make the server fault
tolerant.
Fault tolerance is the ability to continue work when a hardware failure occurs on a system. A fault-tolerant
system is designed from the ground up for reliability by building multiples of all critical components, such as
CPUs, memories, disks and power supplies into the same computer. In the event one component fails, another
takes over without skipping a beat.
Answer options A, C, and D are incorrect. The following steps will make the server fault tolerant:
Adding a second power supply unit
Adding one more same sized disk as a mirror on the server implementing cluster servers facility
