   What is a key benefit of flexible RAID in PowerMaxOS 10?

   • AIt allows different RAID protections to be applied to different storage groups, optimizing data protection and capacity utilization
   • BIt enables the system to automatically select the best RAID level for each workload
   • CIt provides a fixed set of RAID levels that cannot be changed after initial configuration
   • DIt allows RAID groups to be dynamically resized without any downtime

   A defense contractor is deploying a PowerMax 8500 with D@RE. The security team requires that encryption keys be stored externally, not on the array. The storage team also needs to support legacy mainframe workloads that use emulated CKD devices. What is the correct way to meet both requirements?

   • ADisable D@RE for emulated devices and use external KMS only for native devices.
   • BExport all data to an external encrypted store and disable D@RE.
   • CUse internal key storage and rely on the emulation layer to encrypt data.
   • DConfigure D@RE with an external key management server (KMS) and ensure emulated devices are included in the encryption scope.

   A healthcare provider is deploying a PowerMax 8500 with D@RE and inline compression enabled. The storage team notices that the compression ratio is lower than expected for a database workload. The database contains mostly encrypted data from a third-party application. What is the most likely cause and what should the team do?

   • AThe RAID level is too high; the team should switch to RAID 0 to improve compression.
   • BThe compression is disabled on the specific pool; the team should enable it on the database pool.
   • CThe compression algorithm is not compatible with D@RE; the team should disable D@RE to improve compression.
   • DThe data is already encrypted, so compression has little effect; the team should verify that D@RE is not double-encrypting and accept the lower ratio.

   A telecom company is migrating from an older array to a PowerMax 8500. The existing environment uses a proprietary host-based volume manager that expects specific device characteristics. The company also has a compliance requirement to encrypt all data at rest. The storage team is concerned that emulation might interfere with D@RE. What should they do?

   • AUse host-based encryption instead of D@RE to avoid any potential conflict with emulation.
   • BEnable D@RE only on non-emulated devices to avoid conflicts.
   • CDisable emulation and use native device presentation to ensure D@RE works correctly.
   • DUse emulation to present the expected device characteristics and enable D@RE, which works independently of emulation.

   What is the role of GuestOS in the PowerMaxOS 10 environment?

   • AIt is a protocol used to connect hosts to the array
   • BIt provides a separate operating system for managing the array hardware
   • CIt allows the array to run virtual machines for application workloads
   • DIt is a management tool for configuring the array's network settings
