How does service arbitrage differ from service aggregation?
AServices are not free
BServices are not fast
CServices are not full
DServices are not fixed
Answer & Solution
Correct answer: D. Services are not fixed
1. Both combine services from more than one source.
2. One of them can change which sources it uses.
3. Service arbitrage is similar to aggregation except that the services being aggregated are not fixed.
4. So the answer is services are not fixed.
