https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#add-or-copy https://docs.docker.com/engine/reference/builder/The given solution is correct, and it meets the goal of adding a file named File1.txt from Server1 to a folder named C:\Folder1 in the container image.
Explanation:
A Dockerfile is a script that contains a set of instructions to build a container image. The COPY command is used to copy files from the host machine to the container image. In the given solution, the COPY command is used to copy the file named File1.txt from Server1 to a folder named C:\Folder1 in the container image.
The syntax for the COPY command is as follows:
COPY <src> <dest>
Here, <src> specifies the path of the file or folder to be copied from the host machine, and <dest> specifies the path of the file or folder in the container image.
In the given solution, the <src> parameter is File1.txt, which specifies the name of the file to be copied from Server1. The <dest> parameter is C:/Folder1/, which specifies the path of the folder in the container image where the file needs to be copied.
Therefore, the solution is correct, and it meets the goal of adding a file named File1.txt from Server1 to a folder named C:\Folder1 in the container image. Answer A. Yes is the correct answer.
