At 2:00 a.m each day, the database team runs a batch job to import the sales data for the day, index it, and generate sales reports for the next day. The team has informed the cloud administrator that sales data is expected to increase in the next month and will take longer to complete. The current environment uses several batch servers that process chunks of data individually.
Which of the following is the BEST approach for the cloud administrator to take to handle the increased load?

A. Reschedule the nightly batch job to start at midnight to allow for more processing time.
B. Configure an auto-scaling group for the existing batch processing servers.
C. Manually add more batch processing servers to the cloud environment.
D. Increase the CPU and memory resources to the existing batch processing servers.
