When faced with limited connectivity issues where the device receives an IP address but cannot access resources, checking Network Access Control (NAC) settings is a smart first step. NAC might be restricting the laptop based on certain security policies or compliance with the system's requirements. The incorrect answers involve either steps that are less likely to be the direct cause of the issue or should be performed after ensuring NAC settings are not the source of the issue. DHCP scope issues would not typically allow for IP address allocation, SSID mismatch would prevent the device from connecting to the wireless network entirely, and checking the Ethernet cable would not be relevant for a wireless connection.
