Refer to the exhibit. What is created by the configuration?

An L3Out (Layer 3 Outside) is a separate construct for external routing and is not directly created by configuring subnets within an existing bridge domain.

The configuration is creating subnets *within* a bridge domain, not creating an L3OUT-1 bridge domain itself, as the bridge domain would already exist to contain the subnets.

Based on the implied exhibit showing multiple subnet configurations nested under a Bridge Domain (BD) object, the configuration creates three separate subnets that all belong to and are advertised by that specific BD.

A CTX1 tenant is a higher-level organizational construct in ACI, which contains BDs and subnets, but the configuration specifically shown implies subnet creation, not tenant creation.
