Implementing Secure Solutions with Virtual Private Networks (SVPN) — Question 139

Which Diffie Hellman group should be used when ECDH is required in a VPN configuration?

Answer options

• A. 24
• B. 19
• C. 16
• D. 15

Correct answer: B

Explanation

The correct answer is B, as Diffie Hellman group 19 provides sufficient security levels for Elliptic Curve Diffie-Hellman (ECDH) key exchange in VPN configurations. The other groups, such as 15, 16, and 24, either do not meet the necessary security requirements or are not optimized for ECDH.
