Question
Which of the following is an example of load balancing?
- A. Round robin Correct
- B. Active-active
- C. Active-passive
- D. Failover
Explanation
Round robin is a load-balancing method: the balancer hands each new request to the next server in the pool in turn, spreading the load evenly. Active-active and active-passive describe how clustered nodes are arranged for availability, and failover is the act of moving service to a standby node after a failure. Active-active clusters can share load, but the term describes the cluster design, not a load-balancing algorithm.
