Nuyp: Wpd - FTP Internal Cluster Assessment

Explanation
FTP stands for File Transfer Protocol. It is a standard network protocol that is used to transfer files from one host to another over a TCP-based network, such as the internet. FTP provides a simple and reliable way to transfer files between computers, allowing users to upload, download, and manage files on remote servers. It is commonly used by web developers and administrators to update websites, transfer large files, and perform backups.

Explanation
During the 1980s, FTP (File Transfer Protocol) started to gain widespread usage. This protocol allowed for the transfer of files between computers on a network. As computer networks became more prevalent during this time, FTP became a popular method for sharing and transferring files. Its simplicity and efficiency made it a widely adopted standard in the 1980s, contributing to its widespread use during that decade.

Explanation
The 'IIS' in IIS Manager stands for Internet Information Services. IIS is a web server software package developed by Microsoft that allows for the hosting of websites and web applications on Windows servers. IIS Manager is a graphical user interface tool that allows administrators to manage and configure IIS servers.

Explanation
SSL stands for Secure Sockets Layer. It is a cryptographic protocol that provides secure communication over a network, typically between a web server and a web browser. SSL ensures that data transmitted between the server and the browser remains encrypted and cannot be intercepted or tampered with by unauthorized individuals. It is commonly used to secure online transactions, such as credit card payments, online banking, and sensitive data transfers. SSL certificates are used to verify the identity of the server and establish a secure connection.

Explanation
The default gateway IP address is the IP address that allows devices on a network to communicate with devices on another network. It is typically assigned to the router that connects the local network to the internet. The subnet mask, on the other hand, is used to determine the network portion of an IP address. It helps in identifying which part of the IP address represents the network and which part represents the host. Although both the default gateway and subnet mask are important for network communication, they serve different purposes. Therefore, the correct answer is subnet mask.

Explanation
Port 21 is the default port used by the FTP (File Transfer Protocol) for communication. By opening port 21, it allows incoming connections to the FTP server, making it reachable from the internet. This means that users can connect to the FTP server and transfer files using FTP clients. Therefore, the statement "Port 21 needs to be open in order for your FTP to be reachable from the internet" is true.
