QUESTION 24 OF 30

Can you explain DMVPN?

The interviewer will ask you this question for two reasons. One is to ensure that you understand some of the more common technologies used within VPNs. The second is to give them an example of how you explain complex topics to individuals with non-technical backgrounds. They expect your answer to be clear and concise and absent of any jargon, acronyms, or complex terminology which may be difficult to understand. This is important since you will be collaborating with people from outside of the technology organization in this role.

"DMVPN stands for Dynamic Multipoint Virtual Private Network. This protocol allows an IPsec VPN network to scale across different topologies. These include hub-to-spoke and spoke-to-spoke. DMVPN optimizes the performance and reduces the latency between the nodes on the network. Some of the benefits this protocol provides include reducing router configuration on the hub, support for dynamic routing protocols, enabling multicast traffic from the hub to the spokes, and establishing an IPsec tunnel between the spokes, thereby avoiding having to send traffic through the hub."
