Actual exam question for CompTIA's 220-1202 exam
Question #: 118
Topic #: 1
A technician is setting up a surveillance system for a customer. The customer wants access to the system's web interface on the LAN via the system's IP address. Which of the following should the technician use to prevent external log-in attempts from the internet?

Suggested Answer: A Vote an answer

Comprehensive and Detailed Explanation From Exact Extract:
To prevent external access, the technician should avoid exposing the surveillance system's port to the public internet. Port mapping (also known as port forwarding) is the method used to control which internal devices and ports are accessible from the outside. By not configuring port forwarding for the device, external login attempts are effectively blocked.
B: Subnetting organizes IP addresses but doesn't directly restrict access.
C: A static IP ensures consistent addressing but does not secure access.
D: Content filtering is used to restrict web content, not to block access to a web interface.
