To ensure that 10 new web servers (twice the capacity of existing servers) receive twice the connections of old servers while keeping the default load-balancing method, what weight should be assigned to the new servers?

• A. 50; new
• B. 50; old
• C. 2; new
• D. 2; old

Answer: (C)

In a load balancer that distributes traffic based on weights, the weight you assign to a group of servers determines how much traffic that group should receive relative to others. If the new servers have double the capacity of the existing ones, you reflect that by giving them double the weight. So set the weight to 2 for each new server and keep the old servers at their default weight (1). With ten new servers at weight 2 each, versus the old servers at weight 1, the new group will receive twice as many connections as the old group (the new total weight is 20 compared to 10 for the old group, yielding a 2:1 distribution). This matches the goal of delivering twice the connections to the new servers while using the default weighting method.
