Validate understanding

Docker Academy: Knowledge assessment

Test whether you can explain concepts, select controls and reason through production trade-offs.

01Which design or operational decision best demonstrates production understanding of Dockerfile?

A strong answer should use these outcomes: Order layers effectively; Pin dependencies; Use non-root runtime. It should also explain risk, evidence and rollback.

02Which design or operational decision best demonstrates production understanding of Images?

A strong answer should use these outcomes: Inspect image history; Use immutable references; Reduce image size. It should also explain risk, evidence and rollback.

03Which design or operational decision best demonstrates production understanding of Containers?

A strong answer should use these outcomes: Understand lifecycle; Set resources; Handle signals. It should also explain risk, evidence and rollback.

04Which design or operational decision best demonstrates production understanding of Volumes?

A strong answer should use these outcomes: Select volume types; Plan ownership; Back up data. It should also explain risk, evidence and rollback.

05Which design or operational decision best demonstrates production understanding of Networks?

A strong answer should use these outcomes: Use bridge networks; Publish ports safely; Troubleshoot connectivity. It should also explain risk, evidence and rollback.

06Which design or operational decision best demonstrates production understanding of Docker Compose?

A strong answer should use these outcomes: Define services; Use health checks; Manage dependencies. It should also explain risk, evidence and rollback.

07Which design or operational decision best demonstrates production understanding of Registries?

A strong answer should use these outcomes: Authenticate securely; Design retention; Promote immutable images. It should also explain risk, evidence and rollback.

08Which design or operational decision best demonstrates production understanding of Container Security?

A strong answer should use these outcomes: Use minimal bases; Drop capabilities; Scan and sign images. It should also explain risk, evidence and rollback.
