Question: What is a primary benefit of using the Bridge Certificate Authority (Bridge CA) approach in Network Domain Security (NDS) for SEGs (Security Gateways)?
Option 1: Reduced Computational Overhead During IKE Negotiation
Option 2: Minimized Storage Requirements in SEGs by Only Storing the Bridge CA Certificate
Option 3: Enhanced End-to-End Encryption for All Operator Communications
Option 4: Simplified Certificate Management Across Different Operator Networks
Explanation: The Bridge CA approach is advantageous because it significantly reduces the storage needs in Security Gateways (SEGs). By only storing the Bridge CA certificate, SEGs can retrieve other necessary certificates during the Internet Key Exchange (IKE) negotiation process, thus optimizing memory or storage space.
