You have been asked to design the storage layer for an application. The application requires disk performance
of at least 100,000 IOPS in addition, the storage layer must be able to survive the loss of an individual disk. EC2
instance, or Availability Zone without any data loss. The volume you provide must have a capacity of at least 3
TB.Which of the following designs will meet these objectives’?
A.
Instantiate an 12 8xlarge instance in us-east-1a Create a RAID 0 volume using the four 800GB SSD
ephemeral disks provided with the instance Provision 3×1 TB EBS volumes attach them to the instance and
configure them as a second RAID 0 volume Configure synchronous, block-level replication from the ephemeralbacked volume to the EBS-backed volume.
B.
Instantiate an 12 8xlarge instance in us-east-1a create a raid 0 volume using the four 800GB SSD ephemeral
disks provide with the Instance Configure synchronous block-level replication to an Identically configured
Instance in us-east-1b.
C.
Instantiate a c3 8xlarge Instance In us-east-1 Provision an AWS Storage Gateway and configure it for 3 TB of
storage and 100 000 lOPS Attach the volume to the instance.
D.
Instantiate a c3 8xlarge instance in us-east-i provision 4x1TB EBS volumes, attach them to the instance, and
configure them as a single RAID 5 volume Ensure that EBS snapshots are performed every 15 minutes.
E.
Instantiate a c3 8xlarge Instance in us-east-1 Provision 3x1TB EBS volumes attach them to the instance, and
configure them as a single RAID 0 volume Ensure that EBS snapshots are performed every 15 minutes.
