352-001 Question #350: Real Exam Question with Answer & Explanation

The correct answer is B: DMVPN supports multicast replication at the hub.. DMVPN supports multicast replication at the hub and enables dynamic partial- or full-mesh tunnel creation between spokes. These are fundamental architectural characteristics of Cisco's DMVPN solution.

Question

On a large-scale DMVPN network design, what are two DMVPN characteristics? (Choose two.)

Options

ADMVPN can interoperate with other vendors' equipment.
BDMVPN supports multicast replication at the hub.
CDMVPN supports non-IP protocols.
DDMVPN supports dynamic partial- or full-mesh tunnels.

Explanation

DMVPN supports multicast replication at the hub and enables dynamic partial- or full-mesh tunnel creation between spokes. These are fundamental architectural characteristics of Cisco's DMVPN solution.

Common mistakes.

A. DMVPN is a Cisco-proprietary technology stack combining mGRE, NHRP, and IPsec in a specific way that does not guarantee interoperability with non-Cisco equipment.
C. DMVPN relies on mGRE tunnels and NHRP, both of which require IP as the transport protocol, making it unable to carry non-IP protocols natively.
