Question: In a telecom operator's network, utilizing multiple TLS client and server CAs is technically feasible but what primary scenario might necessitate this configuration?
Option 1: To enhance security by distributing trust across multiple Certificate Authorities.
Option 2: For load balancing to improve the efficiency of authentication processes.
Option 3: When transitioning CA functions from one responsible organization to another (e.g., outsourcing of CA services).
Option 4: To accommodate different types of User Equipment (UE) with varying TLS requirements.
Explanation: Having multiple TLS client and server CAs in an operator's network is not the standard approach but might be necessary for transitional phases, such as when CA responsibilities are being shifted from one organization to another. This could include scenarios like outsourcing CA services, where both the old and new organizations' CAs might temporarily coexist to ensure continuity of service.
