Implementing Secure Solutions with Virtual Private Networks (SVPN) — Question 9

Which technology is used to send multicast traffic over a site-to-site VPN?

Answer options

• A. GRE over IPsec on IOS router
• B. GRE over IPsec on FTD
• C. IPsec tunnel on FTD
• D. GRE tunnel on ASA

Correct answer: A

Explanation

The correct answer is A because GRE over IPsec on an IOS router allows for the encapsulation of multicast traffic, which is necessary for site-to-site VPNs. The other options, while they involve IPsec or GRE, do not support multicast traffic transmission in the same manner as option A.
