   A government agency is deploying a PowerMax 8500 to store classified data. The security policy mandates that all data at rest must be encrypted, and the storage team wants to ensure that encryption is enforced without requiring host-side changes. The system will also host legacy applications that rely on emulated devices. What should the administrator configure?

   • AEnable host-based encryption on each server and disable D@RE to avoid double encryption.
   • BConfigure D@RE only for the emulated devices and leave native devices unencrypted.
   • CUse RAID 6 with self-encrypting drives (SEDs) and disable D@RE.
   • DEnable D@RE on the array, which encrypts all data at rest automatically, including data on emulated devices.
