Question: In a Fixed Access Network, which of the following is NOT a mandatory component of the Fixed-User-Location-Info AVP (AVP code 2825) as per 3GPP specifications?
Option 1: SSID (Network Identifier)
Option 2: BSSID (Basic Service Set Identifier)
Option 3: AVP Header: 2825 (Fixed-User-Location-Info AVP Code)
Option 4: Logical-Access-ID
Explanation: The AVP Header with code 2825 is inherently required for the Fixed-User-Location-Info AVP itself, making it a fundamental part rather than a component that could be considered mandatory or optional in the context of the question. Among the provided options, SSID, BSSID, and Logical-Access-ID are all listed as optional components ([SSID] [BSSID] [Logical-Access-ID]) within the Fixed-User-Location-Info AVP format, indicating they can be included but are not necessarily always present. The AVP Header: 2825, however, is the identifier for this AVP and thus always present by definition, making it an incorrect choice in the context of being "NOT a mandatory component" as the question implies looking for an optional field among the choices given.
