Exam 1Z0-1124-24 Topic 1 Question 82 Discussion

Public peering (A): This option utilizes the public internet, exposing your traffic to potential interception and attacks. It offers minimal security and is not recommended for secure communication.
Direct physical connection (B): While eliminating the public internet, this option might require complex setup and ongoing maintenance. Depending on the providers, additional security measures might be needed to restrict access and communication channels.
GRE tunnels over the internet (D): This option only encrypts the tunnel itself, leaving the underlying data vulnerable to attack on the public internet.
IPSec tunnels over a dedicated private network (C): This combination provides the best balance of security and practicality:
IPSec encryption: This industry-standard protocol secures data within the tunnel, protecting it from unauthorized access.
Dedicated private network: By bypassing the public internet, you eliminate the risks associated with publicly routed traffic. This significantly reduces the attack surface and enhances overall security.
