[from /etc/passwd] root :x:0:0::/home/root:/bin/bash root has a UID of 0 carl :x:0:503::/home/carl:/bin/sh Carl also has a UID of 0, which gives him root-level access equivalent to the root user. [from /etc/sudoers] lee ALL = (ALL) ALL Lee is granted full root access through the sudo command

B (Lee) and E (Bob) are correct because: - **Lee** has the entry `lee ALL = (ALL) ALL` in the `/etc/sudoers` file, granting full root-level command-line access. - **Bob** has the entry `bob ALL = NOPASSWD: SYSADMIN`, allowing root-level access to the `/usr/sbin/tcpdump` command without requiring a password.

Answer is Carl, as they share the same ID as the root, and Lee has the sudoers privileges. The confusion is that Mallory has the root directory listed as her home directory. However, this does not necessarily mean she has root level command line access, but she can view and manipulate files and directories within.

I think it is AB. Lee has an entry in sudoers, allowing him to run any command on the system lee ALL=(ALL) ALL Carl has the userId 0, the same as root. That sounds like a terrible idea to me, he should NOT share the same userId as root. That is like logging into the system as root user. Nothing here indicates to me that Mallory has admin level access.
