I would say D.
C is not about maintenance but about resources.
Maintenance is about HW – replacing failed DIMM,CPU or replacing the whole host for more powerful server.
I will go with D, because its more related with maintenance that every other answers.
Actually it should be C, because that makes the most effect on the maintainance perspective and not CPU And memory! That makes sensce when it is asked for recource perspective!?
I think so, too.
Isn’t the answer C?
Why B and not C ?
