First, the administrator should build the container image using the command docker build -t Test-Container, which creates a Docker image with the specified configuration. To run the container and expose port 9000, the correct command is docker run -p 80:9000 Test-Container, which maps the container's port 9000 to port 80 on the host machine, making the service accessible externally on port 80.

The systemctl reload httpd command reloads the Apache HTTP server configuration without terminating any existing connections. This is ideal for applying configuration changes without disrupting the current web traffic, ensuring seamless operation.

The dnf update command will accomplish the task of installing the most recent versions of packages on a RPM-based OS. This command will check for available updates from the enabled repositories and apply them to the system. The apt-get upgrade command is used to install updates on a Debian-based OS, not a RPM-based OS. The rpm -a command is invalid, as -a is not a valid option for rpm. The yum updateinfo command will display information about available updates, but it will not install them. The yum check-update command will check for available updates, but it will not install them. References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 19: Managing Packages and Software, page 559.

The best commands to use to generate a list of rogue process names that have a TCP listener on a network interface are A. netstat -antp | grep LISTEN and B. lsof -iTCP | grep LISTEN. These commands will show the process ID (PID) and name of the processes that are listening on TCP ports, which can be used to identify any suspicious or unauthorized processes. The other commands are either not specific enough, not valid, or not relevant for this task. For example:

C. lsof -i:22 | grep TCP will only show the processes that are listening on port 22, which is typically used for SSH, and not any other ports.

D. netstat -a | grep TCP will show all the TCP connections, both active and listening, but not the process names or IDs.

E. nmap -p1-65535 | grep -i tcp will scan all the TCP ports on the local host, but not show the process names or IDs.

F. nmap -sS 0.0.0.0/0 will perform a stealth scan on the entire internet, which is not only impractical, but also illegal in some countries.
