NSE 7 – Public Cloud Security 7.2 — Question 4

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

Answer options

• A. You can use GRE-based tunnel attachments.
• B. You can use BGP over IPsec for maximum throughput.
• C. You can combine it with IPsec to achieve higher bandwidth.
• D. It eliminates the use of ECMP.

Correct answer: A

Explanation

The correct answer is A because SD-WAN Transit Gateway Connect allows for GRE-based tunnel attachments, which is a key feature not typically available in traditional SD-WAN setups. Options B and C focus on BGP and IPsec functionalities that do not specifically highlight the unique advantage of GRE attachments, while D incorrectly states that ECMP is eliminated, which is not a defining feature of this technology.
