I believe that the maximum throughput allowed for the client should be calculated based on the total quota of 1 MB/s. Since there are 5 brokers sharing this quota, each broker would be allocated 1/5 MB/s, which amounts to 0.2 MB/s. With a replication factor of 3, the maximum throughput allowed for the client would be 3 x 0.2 MB/s = 0.6 MB/s. Therefore, I believe the correct answer is D) 5 MB/s.

Because with 10 partitions and replication factor of 3, the maximum throughput allowed for the client would be the replication factor multiplied by the quota, which is 3 x 1 MB/s = 3 MB/s. Since there are 5 brokers in the cluster, each of them would handle 3/5 MB/s, so the maximum throughput allowed for the client is 3/5 MB/s = 0.6 MB/s.
