Exam MCIA - Level 1 topic 1 question 65 discussion

A is correct for round-robin alogrithms

In a round-robin load balancing configuration, incoming requests are distributed evenly among the available nodes in the cluster.  Initially, with all four nodes operational, each node receives 25% of the incoming requests (4 nodes × 25% = 100% total distribution).  When two nodes experience a power outage and are blocked from receiving further requests, the load balancer redistributes the incoming requests to the remaining two nodes.  With only two nodes remaining, each of these nodes now receives 50% of the incoming requests (2 nodes × 50% = 100% total distribution).  This redistribution results in a 100% increase in the number of requests received by each remaining node, as they now handle twice the workload compared to the initial configuration.

A. 100% increase in the number of requests received by each remaining node

Should be A.
