Question: Which two functional entities support the Configuration Management Server (CMS) in the context of Mission Critical (MC) services?
Option 1: MME and S-GW
Option 2: SIP AS and HTTP Server
Option 3: eNodeB and MCE
Option 4: PDN GW and HSS
Explanation: In the context of Mission Critical (MC) services, the Configuration Management Server (CMS) relies on specific functional entities for its operation within the signalling control plane. The correct support entities are the Session Initiation Protocol Application Server (SIP AS), which handles session-related management, and the HTTP Server, which manages web-based configuration interactions. These entities enable the CMS to effectively configure MC service applications and manage related data.
