Which Python code creates a VRF in an ACI tenant using the Cobra SDK?

Question

Options

• AVrf(fvTenant(uniMo, 'CustA'), 'CustA_VRF')
• BCtx(Tenant(uniMo, 'CustA'), 'CustA_VRF')
• CVrf(Tenant(uniMo, 'CustA'), 'CustA_VRF')
• DCtx(fvTenant(uniMo, 'CustA'), 'CustA_VRF')

• A
  2% (1)
• B
  92% (45)
• C
  2% (1)
• D
  4% (2)

Explanation

Option B is correct because the Cobra SDK uses Ctx (short for "Context") as the Python class name for a VRF - ACI internally models VRFs as fvCtx objects, and Cobra exposes this as Ctx - and Tenant as the proper SDK class for fvTenant.

• A fails on two counts: Vrf is not a valid Cobra SDK class (ACI never uses "VRF" as an object name), and fvTenant is the raw ACI managed object name, not the SDK's Python class.
• C uses the correct Tenant class but still uses the non-existent Vrf class; ACI/Cobra has no such identifier.
• D uses the correct Ctx class but passes fvTenant(...) instead of Tenant(...); in Cobra SDK you use the shortened Python class names (Tenant, Ctx), not the raw MO names like fvTenant.

Memory tip: ACI calls a VRF a "Context," so in Cobra SDK it's always Ctx, never Vrf. If you see Vrf in an answer, eliminate it immediately.
