Worked example. The correct answer is already marked and every option is explained below, so there is nothing to select here. To answer questions yourself, start the free trial.
An enterprise is deploying a mission-critical transactional database on Google Cloud Compute Engine. The architecture team has determined that the database workload requires a minimum of 25,000 sustained read and write IOPS with at least 800 MiBps throughput to satisfy peak business traffic.
The database administrator attached a 1,000 GiB pd-ssd (SSD Persistent Disk) volume to an instance with 4 vCPUs, but performance monitoring reveals that the disk operations are capped well below the target 25,000 IOPS and 800 MiBps.
Which adjustment should the cloud architect recommend to achieve the required disk performance?
