LPIC-3 Exam 305 (Virtualization and Containerization) — Question 6

Which of the following statements in a Dockerfile leads to a container which outputs hello world? (Choose two.)

Answer options

• A. ENTRYPOINT "echo Hello World"
• B. ENTRYPOINT [ "echo hello world" ]
• C. ENTRYPOINT [ "echo", "hello", "world" ]
• D. ENTRYPOINT echo Hello World
• E. ENTRYPOINT "echo", "Hello", "World"

Correct answer: B, C

Explanation

The correct answers are B and C because they both use the correct syntax for the ENTRYPOINT instruction in a Dockerfile, allowing the container to execute the echo command properly. Option A is incorrect because it lacks the proper array syntax, while options D and E are also incorrect due to improper formatting of the ENTRYPOINT command.
