Answers
D.
Misconfigured access point
Suggested answer: A

Explanation:

The most likely cause of the device being accessible via the LAN but not remotely is firewall settings.

A firewall is a software or hardware device that filters incoming and outgoing network traffic based on rules and policies. A firewall can block or allow traffic based on factors such as source and destination IP addresses, ports, protocols, and applications. If the firewall settings are too restrictive or misconfigured, they may prevent remote access to the device from outside the LAN. Improper switch configuration is unlikely to cause this issue, as switches are devices that forward packets within the same network segment based on MAC addresses. Switches do not block or filter traffic based on IP addresses or ports. Incorrect IP address is unlikely to cause this issue either, as an incorrect IP address would prevent the device from communicating with any other device on the network, not just remotely. Misconfigured access point is also unlikely to cause this issue, as access points are devices that provide wireless connectivity to the network. If the device is connected via a wired network, the access point is irrelevant.
