400-007 Question #48: Real Exam Question with Answer & Explanation
The correct answer is A: will only work with single-tier headend architecture. Dual hub dual DMVPN cloud topology places two hubs in a single-tier headend architecture, with each hub anchoring its own DMVPN cloud to provide redundancy and high availability.
Question
Which two aspects are considered when designing a dual hub dual DMVPN cloud topology? (Choose two )
Options
- Awill only work with single-tier headend architecture
- Bhub sites must connect to both DMVPN clouds
- Crecommended for high availability
- Dspoke-to-spoke traffic will transit the hub unless spokes exchange dynamic routing directly
- Erequires all sites to have dual Internet connections
Explanation
Dual hub dual DMVPN cloud topology places two hubs in a single-tier headend architecture, with each hub anchoring its own DMVPN cloud to provide redundancy and high availability.
Common mistakes.
- B. In dual hub dual DMVPN, each hub anchors only one DMVPN cloud - spokes have tunnel interfaces into both clouds, but each individual hub does not connect to both clouds.
- D. Spoke-to-spoke traffic behavior is determined by DMVPN phase selection (Phase 1 hubs traffic, Phase 2/3 allows direct spoke tunnels), not by whether a dual hub dual cloud topology is used.
- E. Spoke sites do not require dual Internet connections - a single connection can carry tunnel interfaces to both DMVPN clouds using separate logical tunnel endpoints.
