A Linux administrator is testing a configuration script and wants to change the hostname of a workstation temporarily, but it must return to its assigned workstation name after reboot. Which of the fo

The hostnamectl set-hostname --transient command writes only to the kernel's runtime hostname, which is held in memory and automatically discarded when the system reboots. This satisfies the requirement of a temporary change while preserving the original static hostname stored in /etc/hostname.

The -H flag in hostnamectl targets a remote host over SSH for operations, not the local machine, and does not set any type of hostname.

hostnamectl set-hostname without a type flag sets all three hostname types (static, pretty, and transient) simultaneously, making the change permanent across reboots via /etc/hostname.

The --static flag explicitly writes the hostname persistently to /etc/hostname, which survives reboots and does not meet the requirement for a temporary, non-persistent change.
