Answer options

• A. shutdown -r now
• B. shutdown -r "rebooting"
• C. telinit 6
• D. telinit 0
• E. shutdown -k now "rebooting"

Correct answer: A, C

Explanation

The commands 'shutdown -r now' and 'telinit 6' are valid for rebooting a system using SysV init. The other options either do not initiate a reboot (like 'telinit 0' which is for halting) or are not valid commands for rebooting at all.
