The correct answer is D. Increase the CPU and memory resources to the existing batch processing servers. To address increasing sales data volume and prevent batch job overruns, the cloud administrator should vertically scale existing batch servers by increasing their CPU and memory resources.

Question

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?

Options

  • AReschedule the nightly batch job to start at midnight to allow for more processing time.
  • BConfigure an auto-scaling group for the existing batch processing servers.
  • CManually add more batch processing servers to the cloud environment.
  • DIncrease the CPU and memory resources to the existing batch processing servers.

Why each option

To address increasing sales data volume and prevent batch job overruns, the cloud administrator should vertically scale existing batch servers by increasing their CPU and memory resources.

AReschedule the nightly batch job to start at midnight to allow for more processing time.
BConfigure an auto-scaling group for the existing batch processing servers.

Mirroring to a third site from the primary site is a form of replication for disaster recovery, not a backup method, and would still consume resources at the primary site for initial synchronization.

CManually add more batch processing servers to the cloud environment.

Agent-based backup at the primary site would install agents directly on the production VMs, consuming primary site resources (CPU, memory, disk I/O) and impacting production performance during backup operations.

DIncrease the CPU and memory resources to the existing batch processing servers.Correct

Concept tested: Backup strategies for replicated VMs without production impact
