How many vBond controllers must be installed when vManager is installed in a multitenancy environment for four tenants?

Community Insight
This question tests the shared nature of the vBond orchestrator in Cisco SD-WAN multitenancy; the trap is assuming tenant isolation extends to a dedicated vBond per tenant.
Cisco SD-WAN multitenancy allows a service provider to host multiple tenants, but the vBond orchestrator remains a single shared control-plane component. For four tenants, only one shared vBond controller is required, making option A correct.
The most common wrong choice is D, which assumes each of the four tenants requires a dedicated vBond controller; Cisco's multitenancy architecture shares one vBond across all tenants.

Why the Answer Is Correct
In Cisco SD-WAN multitenancy, the service provider hosts multiple tenants on vManage, but the vBond orchestrator is a shared control-plane component that authenticates and orchestrates WAN edge devices across all tenants. The vBond does not need to be duplicated per tenant; it serves as the common rendezvous point for every overlay device added to the network. Therefore, whether the provider has one tenant or four tenants, a single shared vBond controller is sufficient for the multitenancy deployment. As abvga noted, "vBond Orchestrators serve WAN edge devices of multiple tenants" as devices are added to the overlay.Why the Other Options Are Wrong
Option B is incorrect because Cisco SD-WAN does not require exactly three vBond controllers in a multitenancy deployment; the number of vBonds is not tied to the tenant count. Option C is wrong because per-tenant vBond redundancy is not a multitenancy sizing rule, and two vBonds per tenant would unnecessarily multiply the orchestrator layer. Option D is the most tempting distractor because it applies per-tenant isolation to the wrong component: while vManage and vSmart resources are partitioned by tenant, the vBond remains shared. No Cisco SD-WAN multitenancy design calls for a dedicated vBond for each tenant.Community Comment Notes
All visible learner votes selected option A, which matches the official architecture. Knowledge33 cited Cisco documentation stating that a "service provider can manage multiple customers, called tenants, from Cisco vManage," reinforcing that vManage is the tenant-aware component, not vBond. Outlaw_87 also chose A, and the unanimous community pick reflects the shared-vBond design principle tested here.Official Reference
Exam Strategy
In multitenancy sizing questions, remember that vBond is a shared provider-level orchestrator; do not multiply it by tenant count. Focus per-tenant scaling on vManage and vSmart, and treat vBond redundancy as a separate high-availability design choice.
Frequently Asked Questions
Does each tenant in SD-WAN multitenancy need a dedicated vBond controller?
No. The vBond orchestrator is shared across all tenants, so four tenants still use one shared vBond (A).
Why is three vBond controllers (option B) wrong for multitenancy?
Cisco SD-WAN does not require three vBond controllers in multitenancy; the orchestrator count is not tied to tenant count, and a single shared vBond serves all tenants.
