Which command sequence installs the latest available package and updates the system to satisfy dependencies on RHEL 8/9?

• A. dnf upgrade; dnf install packagename
• B. yum install packagename; yum update
• C. dnf install packagename; dnf upgrade
• D. rpm -i packagename; dnf update

Answer: (C)

On Red Hat systems with DNF, you install a specific package and then update the rest of the system to satisfy any dependencies or new versions. Running the install command for the package brings in that package at the latest available version and resolves its immediate dependencies. Immediately following with a full system upgrade updates all already-installed packages to their newest releases, ensuring that any dependency changes are satisfied and the system is fully current. This two-step sequence guarantees you get the latest version of the requested package and a coherent, up-to-date system overall. Using an rpm install would not resolve or update other packages, and while yum is available, DNF is the modern default on RHEL 8/9, so this approach using DNF is the correct pattern. (For best practice, you might chain the commands with && so the upgrade runs only if the install succeeds.)
