What is the main advantage of using SD-WAN Transit Gateway Connect over traditional SD- WAN?

Question

Options

• AIt eliminates the use of ECMP
• BYou can use GRE-based tunnel attachments
• CYou can combine it with IPsec to achieve higher bandwidth
• DYou can use BGP over IPsec for maximum throughput

Explanation

Simplified and Scalable Connectivity: Transit Gateway Connect allows you to establish GRE tunnels to your SD-WAN appliances natively within the AWS network. This eliminates the complexity of managing individual IPsec VPN connections, especially as your cloud presence Potential for Enhanced Performance: GRE offers lower overhead compared to IPsec, which can result in higher throughput for bandwidth-intensive SD-WAN applications. Flexibility: While IPsec is supported for scenarios requiring strong encryption, the focus on GRE highlights the performance and scalability benefits that are often prioritized when integrating SD- Dynamic Routing: The integration with BGP further streamlines network management by automating route updates and distribution. Addressing the IPsec Consideration: It's important to acknowledge that SD-WAN Transit Gateway Connect does support IPsec. If your question is specifically framed within the context of Fortinet's FCSS 7.2 materials and they emphasize the hybrid usage of GRE and IPsec, then a modified answer might be appropriate:
