ABased upon the way the question is worded and the four possible answers, I would select “d. all of the above.” I would base my answer on the strategic use of the term redundancy.

Accordingto the Uptime Institute’s White Paper entitled, Tier ClassificationsDefine Site Infrastructure Performance, “The components beyond thenumber of capacity units required to support the computer equipment arereferred to as redundant. If one unit of capacity is required tosupport the computer equipment, more than one unit of capacity isinstalled. Terms such as N+1 or N+2 are commonly applied.”

Using this definition, the other answers are not suitable. None are truly redundant.

The white paper referred to above is available from the Uptime Institute to registered users here.
