Which Markov model state transition correctly represents a two-component active parallel system with identical failure rate λ and repair rate μ?
-
A
States: both-up → one-up → failed; transitions depend on 2λ and λ from each state
-
B
States: both-up → one-up → failed; transitions are λ from both states and μ from failed only
-
C
States: both-up → one-up → failed; transitions are 2λ, λ, and μ at each repair state
-
D
States: both-up → failed; no intermediate state needed
