A SysOps Administrator Is Implementing Automated I/O Load Performance Testing

Multiple Choice

A SysOps administrator is implementing automated I/O load performance testing as part of the continuous integration/continuous delivery (CI/CD) process for an application. The application uses an Amazon Elastic Block Store (Amazon EBS) Provisioned IOPS volume for each instance that is restored from a snapshot and requires consistent I/O performance. During the initial tests, the I/O performance results are sporadic. The SysOps administrator must ensure that the tests yield more consistent results. Which actions could the SysOps administrator take to accomplish this goal? (Choose two.)

A) Restore the EBS volume from the snapshot with fast snapshot restore enabled.
B) Restore the EBS volume from the snapshot using the cold HDD volume type.
C) Restore the EBS volume from the snapshot and pre-warm the volume by reading all of the blocks.
D) Restore the EBS volume from the snapshot and configure encryption.
E) Restore the EBS volume from the snapshot and configure I/O block size at random.
