When sizing high-availability workloads, how should you plan for failover performance?

A.
size high-availability workloads so performance remains the same even when only one
controller is operational as during normal operation

B.
size high-availability workloads with the expectation there is some degree of performance
degradation when only one controller is operational

C.
size high-availability workloads so performance meets the customer’s expectations when there
is failover and only one controller is
operational

D.
size high-availability workloads with the understanding there is not a way to adjust for
performance degradation when only one controller is
operational
