Which command updates all installed RPM packages except for a specific package?

• A. yum update
• B. yum upgrade
• C. yum update --exclude httpd
• D. rpm upgrade --exclude httpd

Answer: (C)

Using the command `yum update --exclude httpd` effectively updates all installed RPM packages on a system while deliberately excluding the specified package, in this case, `httpd`. This command is beneficial when you want to ensure that all other software remains current while preventing certain packages from being upgraded, perhaps due to compatibility issues or specific configuration requirements. The `yum` package manager provides a simple way to manage RPM packages on Linux systems, with the `update` command being a standard way to refresh installed packages. The `--exclude` option allows for the exclusion of particular packages from the update process. By applying this command, system administrators can maintain tighter control over their environments, ensuring that only desired changes are made. In contrast, other options either do not provide the capability to exclude packages from the update process or utilize incorrect commands. For example, simply using `yum update` would apply updates to all packages without any exclusions, and the `yum upgrade` option is synonymous with `yum update` in many cases but does not offer the exclusion functionality. Additionally, the command `rpm upgrade --exclude httpd` is not valid, as the `rpm` tool does not directly support the `upgrade` command or the exclusion of packages in this manner. Thus
