Correct answer: A

Explanation

The correct answer is A because FlexVPN indeed uses IKEv2, which is a more advanced key management protocol compared to IKEv1 commonly used in traditional DMVPN setups. Options B and D are incorrect because they misstate the key management protocols and the support scope of FlexVPN and DMVPN. Option C is also wrong as it does not accurately represent the phases of operation for these technologies.
