The raw data comes from Amazon S3, and the resulting processed data is also stored in Amazon S3. The processing must complete within 4 hours; currently, it only takes 3 hours. However, the processing time is taking 5 to 10 minutes longer each week due to an increasing volume of raw data.<br \/>\nThe team is also concerned about rising costs as the compute capacity increases. The EMR cluster is currently running on three m3.xlarge instances (one master and two core nodes).<br \/>\nWhich of the following solutions will reduce costs related to the increasing compute needs? <br \/><strong><br \/>A.<\/strong> Add additional task nodes, but have the team purchase an all-upfront convertible Reserved Instance for each additional node to offset the costs. <br \/><strong>B.<\/strong> Add additional task nodes, but use instance fleets with the master node in on-Demand mode and a mix of On-Demand and Spot Instances for the core and task nodes. Purchase a scheduled Reserved Instance for the master node. <br \/><strong>C.<\/strong> Add additional task nodes, but use instance fleets with the master node in Spot mode and a mix of On-Demand and Spot Instances for the core and task nodes. Purchase enough scheduled Reserved Instances to offset the cost of running any On-Demand instances. <br \/><strong>D.<\/strong> Add additional task nodes, but use instance fleets with the master node in On-Demand mode and a mix of On-Demand and Spot Instances for the core and task nodes.
