Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 37

What is a commonality between DMVPN and FlexVPN technologies?

Answer options

• A. FlexVPN and DMVPN use the new key management protocol, IKEv2
• B. FlexVPN and DMVPN use IS-IS routing protocol to communicate with spokes
• C. IOS routers run the same NHRP code for DMVPN and FlexVPN
• D. FlexVPN and DMVPN use the same hashing algorithms

Correct answer: C

Explanation

The correct answer is C because both DMVPN and FlexVPN utilize the same NHRP code within IOS routers, allowing for compatibility and interoperability. Option A is incorrect since FlexVPN primarily supports IKEv2 but DMVPN can also work with IKEv1. Option B is not true because DMVPN typically uses NHRP for communication, not IS-IS. Option D is also wrong; while both may use hashing algorithms, they are not necessarily the same across both technologies.
