Stealth Mode is designed to enhance the security of a computer on a network by minimizing its visibility to unauthorized users. When Stealth Mode is activated, the system will not respond to probing requests from unauthorized sources, effectively rendering it "invisible" to potential attackers who are scanning for vulnerable devices. This makes it significantly more challenging for malicious entities to detect the device or find open ports that could be exploited.

While the system may still be able to send and receive data from authorized applications and known devices, Stealth Mode specifically targets those unsolicited attempts to access or gather information about the system from unauthorized networks. By not responding to these probing requests, the system reduces the risk of being compromised, as attackers often rely on initial reconnaissance to establish a foothold.

In contrast, the other options point to different kinds of network traffic and requests that do not specifically align with the primary mechanism or purpose of Stealth Mode. The emphasis is on blocking responses to unauthorized probing, thereby improving overall security.
