What are two benefits of choosing packet duplication over FEC for data loss correction on noisy links? (Choose two.)
Packet duplication over FEC for data loss correction on noisy links offers two main benefits: it can leverage multiple IPsec overlays for sending additional data, which enhances the efficiency and reliability of data transmission across different paths, and it supports hardware offloading, allowing for faster processing and less burden on the CPU. These advantages make packet duplication a robust choice in specific network environments requiring improved data integrity and performance.
I believe C & D is correct based on info on page 260 in the study guide - - It supports Hardware Offloading so C is correct. - A requirements is that a member used for duplication MUST have a route to the destination. Thus A is incorrect. D I belive is the second correct answer, as you ca nconfigure de-duplication on the receiving Fortigate to save resources on the receiving end.
This is wrong. Packet duplication can leverage multiple IPsec tunnels and it supports Hardware offloading. Thus B & C are correct. I misread page 260 when originally reading it.
It should be B and C
B & C are correct - Page 260 in the 7.2 study guide explains this.
D is incorrect based off of this statement in the Study Guide: "Unlike the parity packets in FEC, which are not exact copies of the original packets, the duplicate packets are verbatim copies of the original packet." Also: "FEC provides an efficient way to reduce data loss on IPsec tunnels. However, FEC doesn't leverage multiple IPsec tunnels. In addition, fec doesn't support hardware offload or links that are not IPsec" - Thus B is correct Duplication supports Hardware Offloading. - C is correct Member must have a route to the destination. - A is incorrect
A is not correct per Study Guide PAge 260. C and D are correct
However also in page 260....mentioned that PD can used IPSec Overlay to send additional copies...B is also in play.....that means I will change my vote to B & D
B& D are the correct answer
B & C are the correct answers
A. wrong - Member must have route to destination C. correct Supports hardware offloading D. Wrong - Packet duplication is using exact identical packets. Parity packets are used in FEC and and not exact copies Unlike the parity packets in FEC, which are not exact copies of the original packets, the duplicate packets are verbatim copies of the original packet. This way, the duplicate packets can be used for data loss protection therefore B is correct
B & C are correct
