• Chose B1

  ## Why the Other Options Are Incorrect A. Local SSD for customer session state data... This is incorrect because Local SSD is ephemeral. All data is lost if the VM instance is stopped or terminated. This violates the requirement for session data to be durable for several days. C. ...Assorted local SSD-backed instances for VM boot/data volumes. This is incorrect for the same reason. Local SSD cannot be used for persistent boot volumes. The data would not survive an instance stop/start. This is a critical architectural error. D. ...Assorted local SSD-backed instances for VM boot/data volumes. This suffers from the same fatal flaw as option C. Using ephemeral Local SSD for persistent VM volumes is not a viable solution.

  None of these provide an effective method of storing boot/data volumes The correct approach would be to create persistent disk Drives for boot/data volumes directly and go with B or D for the remainder of requirements.

  B is correct. the question lays emphasis on a cost-effective storage allocation, and persistent disks are costly than B (that rules out D)
