What MEF SD-WAN attribute ensures logical separation between tenants in a shared environment?

• A. Underlay type
• B. Encryption settings
• C. Tenant isolation
• D. QoS policy

Answer: (C)

Logical separation between tenants in a shared MEF SD-WAN fabric is achieved through tenant isolation. This means each tenant has its own distinct data plane, control plane context, and policy space within the orchestrator, so one tenant’s traffic and management activities cannot intrude on or affect another tenant. This isolation provides privacy, security, and governance in a multi-tenant environment, while still allowing all tenants to share the same physical network.

The other attributes don’t provide that separation. The underlying transport type refers to the physical or transport network used, not how tenants are kept apart. Encryption protects data in transit but doesn’t inherently create boundaries between different tenants sharing the network. QoS policies control traffic prioritization and performance, but they don’t establish tenant boundaries or prevent cross-tenant data or control-plane interactions.
