Question: What is a key consideration for the adoption of Public Key Infrastructure (PKI) in the Network Domain Security (NDS)/Authentication Framework (AF) trust model?
Option 1: Simplicity and ease of deployment to facilitate mesh configuration among multiple operators.
Option 2: Mandatory extension of existing PKI standards to exclusively support specific environments.
Option 3: Exclusive compatibility with GRX providers for secure traffic exchange.
Option 4: Prioritization of leased lines over public Internet for non-GRX operators.
Explanation: The correct answer reflects a key requirement for the NDS/AF trust model, emphasizing simplicity to ensure the technical solution doesn't become a barrier to adoption when numerous operators need to securely exchange traffic in complex configurations.
