Question

Which two commands download and run an Apache web server container in Docker, with port 8080 in the container bound to port 80 on the host?

Choose two

A docker pull apache
B docker run –p 8080:80 httpd
C docker run –p 80:8080 httpd
D docker pull httpd
E docker pull https

Explanation

The official Apache web server image on Docker Hub is 'httpd', so you obtain it with 'docker pull httpd' (D). Docker's -p flag maps ports as hostPort:containerPort; to bind container port 8080 to host port 80 the correct form is 'docker run -p 80:8080 httpd' (C). Option B ('-p 8080:80') reverses the mapping (host 8080 to container 80), and options A/E reference nonexistent/incorrect images ('apache', 'https'). Hence C and D.
