Which of the following is an example of load balancing?
Correct Answer: A. Round robin
Round robin is a load balancing method that distributes incoming requests sequentially across a group of servers. Each new request is forwarded to the next server in the list, cycling back to the first server after reaching the last. This simple, efficient algorithm ensures an even distribution of workload among servers, preventing any single server from becoming overloaded and improving overall system performance and reliability.
Why Other Options are Incorrect:
B. Active-active
Active-active refers to a high-availability setup where multiple systems run simultaneously to provide redundancy and load sharing, but it is not a load balancing method itself. It focuses on availability rather than the specific distribution algorithm of incoming requests.
C. Active-passive
Active-passive is a failover configuration where one system is active and the other is on standby, ready to take over if the active system fails. It does not distribute load between servers and therefore is not a load balancing method.
D. Failover
Failover is a process that switches to a backup system when the primary system fails. It ensures continuity but does not balance the workload across multiple servers, so it is not considered a load balancing technique.
