Which command starts a build for a specific buildconfig named myjava?

• A. oc start-build myjava
• B. oc start-build
• C. oc start-build --name myjava
• D. oc start-build myjava --watch

Answer: (A)

To trigger a new build for a specific BuildConfig, you specify the BuildConfig name as the argument to the command. Saying oc start-build myjava tells OpenShift to start a new build using the BuildConfig named myjava in your current project. The BuildConfig defines how the image should be built, so giving its name directly identifies exactly which build to run.

You can add flags like --watch (or -w) to stream the build logs as it runs, but the essential part is providing the BuildConfig name. Without naming the BuildConfig, the command wouldn’t know which build to start, and options like --name or omitting the name don’t specify the target BuildConfig in the same direct way.
