Exam 312-50v13 topic 1 question 68 discussion

B is the correcto

B. 48101 Usage: This port is not a standard, well-known port (e.g., HTTP, SSH). Some proprietary IoT devices or malware may use arbitrary high ports, but it is not a universal target. Without specific context, blocking a non-standard port like 48101 is less effective than targeting widely used, vulnerable ports (e.g., 22, 80). A. 22 (SSH) Usage: Secure Shell (SSH) is a protocol for remote login and command execution. Many IoT devices (e.g., routers, cameras) use SSH for management, and unsecured SSH ports are a common entry point for attackers.

The port to block first if you suspect an IoT device has been compromised is B. 48101.

correct answer option b 48101

48101 is a specific port used by some IoT devices (e.g., cameras), but less standard — 22 is more critical.
