  1. D is the most probable answer, while answer B may also apply

    I say D because the question is about not being able to access internal or external resources.
    If the resource is internal and on the same subnet as the WiFi client, then a default-gateway isn’t required, but a DNS server is required for both internal and external resources when URL are used to access the resources.

    This is another example of nasty Cisco exam question that doesn’t provide a decent context.

  2. B or D but not C

    Information About DHCP Option 82
    DHCP option 82 provides additional security when DHCP is used to allocate network addresses. It enables the controller to act as a DHCP relay agent to prevent DHCP client requests from untrusted sources. You can configure the controller to add option 82 information to DHCP requests from clients before forwarding the requests to the DHCP server.
