Question: In a Mission Critical (MC) service architecture, what is the primary purpose of the HTTP proxy entity when interacting with an MC service UE's HTTP client and multiple HTTP servers?
Option 1: To establish separate TLS sessions for each HTTP server with the UE's HTTP client.
Option 2: To terminate a single TLS session with the UE's HTTP client, enabling hypertext transactions with multiple HTTP servers.
Option 3: To bypass security protocols for direct HTTP communication between the UE and external HTTP servers.
Option 4: To manage key exchange exclusively for CSC-1 interfaces between the UE and IdM server.
Explanation: The HTTP proxy's role is to terminate a single TLS session with the MC service UE's HTTP client, allowing the UE to establish a secure connection for multiple hypertext transactions with various HTTP servers reachable by the proxy, enhancing efficiency and security within the trust domain of the MC system.
