Question 9

A user cannot access a directory '/data/projects' even though they are in the 'projects' group. The directory permissions are 'drwxr-x---' and the group owner is 'projects'. Which command should the administrator run to grant the group write permission?

Accepted Answer

chmod g+w /data/projects. The directory '/data/projects' has permissions 'drwxr-x---', meaning the group owner 'projects' currently has read and execute (r-x) but not write (w) access. Since the user is a member of the 'projects' group, the administrator needs to add write permission for the group using 'chmod g+w /data/projects'. This directly modifies the group permission bits to grant write access without affecting other permissions.

Answer

chmod o+w /data/projects

Answer

chmod u+w /data/projects

Answer

chown :projects /data/projects

Question 10

A DevOps engineer needs to ensure that a containerized web application always restarts automatically if the container exits unexpectedly. Which Docker run option should be used?

Accepted Answer

--restart=always. The `--restart=always` policy ensures that the container restarts regardless of the exit code or reason for termination, including unexpected crashes. This is the correct choice for a containerized web application that must maintain high availability by automatically recovering from any unexpected exit.

Answer

--restart=on-failure

Answer

--restart=unless-stopped

Answer

--restart=no
