NSE 7 – OT Security 7.2 — Question 14

How can you achieve remote access and internet availability in an OT network?

Answer options

• A. Add additional internal firewalls to access OT devices.
• B. Implement SD-WAN to manage traffic on each ISP link.
• C. Create more access policies to prevent unauthorized access.
• D. Create a back-end backup network as a redundancy measure.

Correct answer: B

Explanation

Implementing SD-WAN is the correct choice because it optimally manages traffic across different ISP links, enhancing remote access and internet connectivity. The other options, such as adding firewalls or creating more access policies, do not directly address the need for effective traffic management and internet availability in an OT environment.
