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

question 565

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.
