Question: In a Service Enabler Architecture Layer (SEAL) for Verticals, what is a key role of the SEAL server in relation to other architectural components?
Option 1: The SEAL server solely manages User Equipment (UE) authentication for vertical services.
Option 2: The SEAL server acts as a client to the Common API Framework for 3GPP Northbound APIs.
Option 3: The SEAL server is responsible for direct media transfer between Vertical Application (VA) servers.
Option 4: The SEAL server exposes API functions as part of CAPIF and supports interactions with VAL servers and peer SEAL servers in distributed deployments.
Explanation: This option correctly highlights the SEAL server's dual role: firstly, acting as a part of the Common API Framework by exposing API functions, facilitating standardized interactions; secondly, supporting interactions with both Vertical Application servers and peer SEAL servers in distributed architectures, ensuring scalability and coordination across the SEAL infrastructure.
