Which PAM module enforces password complexity requirements on Linux?
Answer: C. pam_pwquality.so
pam_pwquality.so checks password strength and enforces complexity rules such as minimum length and character classes.
A user named 'alex' is a member of the 'developers' and 'qa' groups. A system administrator needs to add 'alex' to the 'sysadmins' group without removing them from their existing groups. Which of the following commands will accomplish this?
Answer: C. usermod -aG sysadmins alex
The `usermod` command modifies a user account. The `-G` option specifies the supplementary groups. Crucially, the `-a` (append) option must be used with `-G` to add the user to the new group without removing them from their current supplementary groups. Using `-G` alone would replace the user's current group list with the new one.
When using docker run -p 8080:80, what does port 8080 represent?

In -p host_port:container_port format, 8080 is the host port that forwards traffic to port 80 inside the container.
A system administrator is examining a legacy Linux system and needs to quickly display the IP address, MAC address, and traffic statistics for all network interfaces, including those that are down. Which command, though now deprecated, is traditionally used for this purpose?
Answer: C. ifconfig -a

Using the `-a` flag ensures that it displays information for all interfaces, including those that are currently inactive or 'down'. While `ip addr show` is the modern replacement, `ifconfig` is the correct answer for a legacy context.
