CompTIA Cloud+ (CV0-004) — Question 85

Which of the following container commands implements network port mapping?

Answer options

• A. $docker run –it myimage –e /bin/port 8080
• B. $docker run myimage:port
• C. $docker run –it –p 1-65535 myimage –e netstat 8080
• D. $docker run –it –p 80:8080 myimage

Correct answer: D

Explanation

The correct answer is D, as it explicitly uses the '-p' option to map port 80 on the host to port 8080 in the container. Options A and B do not include port mapping commands, while option C attempts to map a range of ports but does not specify a proper mapping format.
