Which statement about Round Robin memory usage is true?

• A. It uses a cache in memory only
• B. The router stores the last route in a relational database
• C. It uses Object Store to remember the last execution
• D. It does not track last route at all

Answer: (C)

Round robin routing needs to know which route was used last so it can send the next request to the subsequent route in the sequence. In MuleSoft, that state is stored in the Object Store, which keeps track of the last execution and lets the router rotate through available routes even across restarts or in a clustered environment. This is why the statement about using Object Store to remember the last execution is the true one—it isn’t limited to a pure in-memory cache, and it does track the last route (not stored only in a relational database by default).
