Answer: Use a slimmed-down base image like Alpine Linux, Copy the source after the package dependencies (Python and pip) are installed
The correct answers are C and E. Using a slimmed-down base image like Alpine Linux (C) helps reduce the size of the Docker image, which can lead to faster deployment times. Additionally, copying the source code after installing the package dependencies (E) makes use of Docker's layer caching mechanism. Since dependencies change less frequently than the application source code, this allows subsequent builds to reuse cached layers for dependencies and only build new layers for the changed source code, thereby speeding up the build process.
