An engineer must design a VPN solution for a company that has multiple branches connecting to a main office. What are two advantages of using DMVPN instead of IPsec tunnels to accomplish this task? (Choose two.)
Correct Answer: B,E
Greater scalability: DMVPN is a more scalable solution than IPsec tunnels. This is because DMVPN uses a hub-and-spoke topology, which allows for the easy addition or removal of spokes without having to reconfigure the entire network. IPsec tunnels, on the other hand, are point-to- point connections, which can be more difficult to scale. Dynamic spoke-to-spoke tunnels: DMVPN supports dynamic spoke-to-spoke tunnels. This means that tunnels are only created between spokes when they need to communicate with each other. This can help to reduce traffic overhead and improve performance. IPsec tunnels, on the other hand, are static tunnels, which means that they are always up, even when they are not needed.
