The IEEE 802.11 standard contains the specifications for Wi-Fi networks. It is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication in various frequencies, including but not limited to 2.4 GHz, 5 GHz, and 6 GHz1. This standard is maintained by the Institute of Electrical and Electronics Engineers (IEEE) and is commonly referred to as Wi-Fi. The standard has evolved over time to include several amendments that improve speed, range, and reliability of wireless networks.

To store files that will be accessible by every user on a network, you would need a server. A server is a computer system that provides data to other computers. It can serve data to systems on a local network (LAN) or a wide network (WAN) over the internet. In this context, a file server would be set up to store and manage files, allowing users on the network to access them from their own devices1.

What is a Server?

Understanding Servers and Their Functions

A server is a computer designed to process requests and deliver data to other computers over a local network or the internet. In this case, to store files that will be accessible by every user on the network, a file server is the appropriate endpoint device. It provides a centralized location for storing and managing files, allowing users to access and share files easily.

A . Access point: Provides wireless connectivity to a network.

C . Hub: A basic networking device that connects multiple Ethernet devices together, making them act as a single network segment.

D . Switch: A networking device that connects devices on a computer network by using packet switching to forward data to the destination device.

Thus, the correct answer is B. Server.

Statement A: 'A detailed description of the fault.' This is essential for support staff to understand the nature of the problem and begin troubleshooting effectively.

Statement C: 'A description of the conditions when the fault occurs.' This helps in reproducing the issue and identifying patterns that might indicate the cause of the fault.

Statement B: 'Details about the computers connected to the network.' While useful, this is not as immediately critical as understanding the fault itself and the conditions under which it occurs.

Statement D: 'The actions taken to resolve the fault.' This is important but typically follows the initial report.

Statement E: 'The description of the top-down fault-finding procedure.' This is more of a troubleshooting methodology than information typically included in an initial support ticket.

Best Practices for Submitting Support Tickets: Support Ticket Guidelines

* Statement B: 'The same default gateway IPv4 address is configured on each host on the local network.' This is true because all hosts on the same local network (subnet) use the same default gateway IP address to send packets destined for other networks.

* Statement D: 'The default gateway is the IPv4 address of the router interface connected to the same local network as the host.' This is true because the default gateway is the IP address of the router's interface that is directly connected to the local network.

* Statement A: 'The IPv4 address of the default gateway must be the first host address in the subnet.' This is not necessarily true. The default gateway can be any address within the subnet range.

* Statement C: 'The default gateway is the Loopback0 interface IPv4 address of the router connected to the same local network as the host.' This is not true; the default gateway is the IP address of the router's physical or logical interface connected to the local network.

* Statement E: 'Hosts learn the default gateway IPv4 address through router advertisement messages.' This is generally true for IPv6 with Router Advertisement (RA) messages, but not typically how IPv4 hosts learn the default gateway address.

SFTP, or Secure File Transfer Protocol, is a protocol that allows for secure file transfer capabilities between networked hosts. It is a secure extension of the File Transfer Protocol (FTP). SFTP encrypts both commands and data, preventing passwords and sensitive information from being transmitted openly over the network. It is typically used for secure file transfers over the internet and is built on the Secure Shell (SSH) protocol1.

* Secure File Transfers: Best Practices, Protocols And Tools

The Secure File Transfer Protocol (SFTP) is a secure version of the File Transfer Protocol (FTP) that uses SSH (Secure Shell) to encrypt all commands and data. This ensures that sensitive information, such as usernames, passwords, and files being transferred, are securely transmitted over the network.

* ICMP (Internet Control Message Protocol) is used for network diagnostics and is not designed for file transfer.

* NTP (Network Time Protocol) is used to synchronize clocks between computer systems and is not related to file transfer.

* HTTP (HyperText Transfer Protocol) is used for transmitting web pages over the internet and does not inherently provide secure file transfer capabilities.

Thus, the correct protocol that allows secure uploading of files to another computer on the internet is SFTP.
