Which of the following commands can be used to instruct the init process to switch runlevels? (Choose TWO correct answers)

telinit is a dedicated command that sends a signal to the running init process to change runlevels (e.g., telinit 3), and is the canonical tool for this purpose in SysV-style systems.

initctl is part of the Upstart init system and manages Upstart jobs and events; it is not used for traditional SysV runlevel switching.

The init binary itself accepts a runlevel argument (e.g., init 3) and communicates the change to the running PID 1 init process, making it a valid alternative to telinit.

reinit is not a real or standard Linux command and does not exist in SysV or Upstart tooling.

runlevel only queries and displays the previous and current runlevel; it cannot instruct init to change runlevels.
