問題文

Three applications each carry the same twelve components that convert an internal order into a partner format. The team wants one copy of that logic reused at build time rather than over the network. What is built?

選択肢

1. A separately versioned project that publishes the conversion as a gateway policy which every application then receives from the platform.
2. A separately versioned project that publishes the conversion as a deployable application which every application then calls over HTTP.
3. A separately versioned project that publishes the conversion as a reusable extension which every application then declares as a build dependency.
4. A separately versioned project that publishes the conversion as a shared configuration which every application then inherits when it starts.
