📚 DCA Topics to Study (32)
✍️ Sample DCA Questions & Answers
1. Which log driver is the default for Docker containers when no driver is explicitly configured?
By default, Docker uses the `json-file` log driver, storing logs as JSON on the host filesystem.
2. You want `docker logs` to follow output in real time, similar to `tail -f`. Which flag do you use?
`docker logs --follow` (or `-f`) continuously streams new log output as the container produces it.
3. A project architect must ensure containers in different Docker networks cannot communicate unless explicitly allowed. What feature enforces this?
Docker network isolation is the default; containers on separate networks cannot communicate unless connected to a shared network.
4. What is the purpose of financial forecasting in DCA practice?
Financial forecasting uses historical data, current trends, and assumptions to project future revenues, expenses, and financial position, supporting strategic planning and resource allocation decisions.
5. A team is planning Docker image layer caching strategy in their CI system. Which Dockerfile instruction order maximizes cache reuse?
Copying only the lockfile and installing dependencies before copying source code allows the dependency layer to be cached across code changes.
6. A project plan calls for image scanning before deployment. Which Docker CLI command initiates a vulnerability scan using Docker Scout?
The 'docker scout cves' command lists known CVEs in an image using the Docker Scout service.

What Practice Test Geeks adds beyond an AI chat for DCA
An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:
- A timed, full-length DCA mock exam — 55 questions in 90 minutes with a 65% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
- A fixed DCA question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable DCA cheat sheet you can print or save as a PDF.
- DCA flashcards built from the same question bank.
- Free DCA practice tests with the correct answer shown after each question.
