• Question 70:

  Refer to the exhibit. An engineer must add new users and set privileges for executing a few Python scripts. The engineer prepares a Bash script to automate this task.

  A. assigning execution privileges to the owner, setting the user and group owner to the scripts that were initially created, and storing the script names in a file

  B. creating a file with the content of all the files, assigning execution permissions to each script, and then changing ownership to the initially created user and group

  C. removing the files that are not Python, listing the Python files, and assigning execution privileges to the initially created user and group

  D. assigning execution privileges to everyone and changing the ownership to the initially created user and group

  Correct Answer: B
