Docker Certified Associate (DCA) — Question 13

Is this an advantage of multi-stage builds?
better caching when building Docker images

Answer options

• A. Yes
• B. No

Correct answer: A

Explanation

The correct answer is A because multi-stage builds allow for more efficient caching by separating the build environment from the final image, which can help in reusing layers that haven't changed. Option B is incorrect as it suggests that there is no advantage in caching when using multi-stage builds, which contradicts the benefits they offer.
