NSE 7 – SD-WAN 7.2 — Question 44

What are two benefits of choosing packet duplication over FEC for data loss correction on noisy links? (Choose two.)

Answer options

• A. Packet duplication does not require a route to the destination.
• B. Packet duplication can leverage multiple IPsec overlays for sending additional data.
• C. Packet duplication supports hardware offloading.
• D. Packet duplication uses smaller parity packets which results in less bandwidth consumption.

Correct answer: B, C

Explanation

The correct answers are B and C because packet duplication can utilize multiple IPsec overlays to send extra data, providing redundancy and reliability. Additionally, it supports hardware offloading, improving performance. Options A and D are incorrect as packet duplication does not eliminate the need for routing to the destination, and it does not inherently reduce bandwidth usage compared to FEC.
