A. B. C. D. E.AE.
The dual hub, dual DM VPN cloud topology is a design model for building a highly available and scalable WAN infrastructure that enables secure communication between multiple sites. This topology provides redundancy at the hub site and allows traffic to be balanced between two hub sites, thereby increasing availability.
The following are the two aspects that are considered when designing a dual hub, dual DM VPN cloud topology:
A. Recommended for high availability: The dual hub, dual DM VPN cloud topology is a recommended design for high availability. With this topology, if one hub site or one DM VPN cloud fails, traffic can be rerouted to the other hub site or DM VPN cloud, providing redundancy and increasing network availability.
C. Spoke-to-spoke traffic will transit the hub unless spokes exchange dynamic routing directly: In the dual hub, dual DM VPN cloud topology, spoke-to-spoke traffic will transit the hub unless spokes exchange dynamic routing directly. This is because the hub sites act as the central points for traffic flow between spokes. If spokes exchange dynamic routing directly, then spoke-to-spoke traffic can be routed directly without passing through the hub sites. This can reduce the load on the hub sites and improve overall network performance.
The other options mentioned in the question are incorrect:
B. Requires all sites to have dual Internet connections: The dual hub, dual DM VPN cloud topology does not require all sites to have dual Internet connections. Instead, it is designed to provide redundancy at the hub site.
D. Hub sites must connect to both DM VPN clouds: This statement is incorrect. The hub sites in the dual hub, dual DM VPN cloud topology can connect to one or both DM VPN clouds, depending on the design requirements.
E. Will only work with single-tier headend architecture: The dual hub, dual DM VPN cloud topology is not dependent on a specific architecture such as a single-tier headend. It is a generic design model that can be implemented in different network architectures to provide redundancy and improve availability.
