In the SVI example, which VRF is the VLAN attached to?

• A. mgmt
• B. eng
• C. default
• D. prod

Answer: (B)

VRF binding of an SVI determines which routing instance a VLAN uses. In the example, the SVI for that VLAN is configured to belong to the engineering VRF, so the VLAN is attached to the eng VRF. This means all IP routing for hosts in that VLAN happens within the engineering routing table, isolating it from other VRFs such as mgmt, default, or prod. Seeing the SVI tied to eng (often shown as vrf forwarding eng or a similar VRF-binding configuration) is why the VLAN is attached to the engineering VRF.
