The correct answer is D. Incorrect SSID. Connecting to an incorrect SSID causes the device to join a different network, receiving an IP from that foreign network's DHCP scope, which explains internet access but inability to reach local resources.
Question
A user is unable to communicate with any local network resources, but is connected to the wireless network and can access the Internet. The network technician notices that the laptop has an incorrect IP address, even though it shows it is connected. Which of the following is the MOST likely cause?
Options
- ASignal strength
- BInterference
- CAP placement
- DIncorrect SSID

Why each option
Connecting to an incorrect SSID causes the device to join a different network, receiving an IP from that foreign network's DHCP scope, which explains internet access but inability to reach local resources.
Poor signal strength would cause intermittent connectivity or complete disconnection, not a condition where the user is fully connected but has an incorrect IP.
Wireless interference degrades signal quality and throughput but would not result in an incorrect IP address being assigned.
AP placement affects coverage and signal strength, not the IP address assigned to a client that successfully connects.
When a user connects to an incorrect SSID, the device associates with a different wireless network and receives an IP address from that network's DHCP server. This IP is incompatible with the local LAN subnet, blocking access to local resources while potentially still allowing internet access through the foreign network's gateway.
