In the following graphic, the administrator created an additional paging space using smit mkps. The paging space is not active. What is necessary to start using the new paging space?
The correct answer is A. Use swapon to activate the new paging space. A paging space created with smit mkps but left in an inactive state can be immediately activated in the running system using the swapon command without requiring a reboot.

Why each option
A paging space created with smit mkps but left in an inactive state can be immediately activated in the running system using the swapon command without requiring a reboot.
The swapon command activates a defined but inactive paging space immediately, making it available to the operating system in the current session. This allows administrators to add swap capacity dynamically without interrupting system availability, which is the intended method for bringing a newly created paging space online.
A reboot is not required to activate a new paging space; swapon provides immediate dynamic activation on a running AIX system.
If the paging space was successfully created using smit mkps, the underlying volume group was already varied on at creation time and does not need to be varied on again.
The chps -a y command sets the auto-activation flag so the paging space activates automatically on the next reboot; it does not immediately activate the paging space in the currently running session.
