What status message indicates a port is accessible with an application accepting connections?

• A. Filtered
• B. Closed
• C. Open
• D. Blocked

Answer: (C)

The status message that indicates a port is accessible and an application is accepting connections is "Open." When a port is marked as open, it means that it is actively listening for incoming connection requests from clients, and there is an application or service ready to handle those requests. Open ports are essential for network communication, allowing various services such as web servers, databases, and email servers to function properly. In contrast, when a port is filtered, it usually indicates that a firewall or network device is blocking access, preventing any connection attempts from succeeding. A closed status means that there is no application listening on that port, and while it is reachable, it won't establish a connection. The term blocked, while somewhat similar to filtered, typically refers to an explicit restriction put in place rather than a state reported by a network scan. Therefore, the term "Open" is the correct terminology that clearly signifies availability for connection on a specified port.
