Question: In a 3GPP system to WLAN interworking scenario, what does the `WLAN_DIRECT_IP_ACCESS` (0) value of the WLAN Direct IP Access AVP indicate about a user's network access?
Option 1: The user can only access internal IP networks within the WLAN Access Network.
Option 2: The user is subject to additional authentication for external IP network access.
Option 3: The user's device is restricted to WLAN-specific services only.
Option 4: The user is allowed direct access to external IP networks, such as the Internet, from the WLAN Access Network.
Explanation: This setting indicates that the user has permission for direct access to external IP networks (e.g., the Internet) via the WLAN Access Network, impacting how users interact with resources outside the immediate WLAN, highlighting its importance in managing network access and security.
