   A storage administrator is considering enabling drive encryption on a high-performance E-Series system that hosts a latency-sensitive database. The administrator is concerned about the performance impact. What is the expected performance impact of drive encryption on E-Series systems?

   • AEncryption will only impact write performance, not read performance.
   • BEncryption will double the latency for all I/O operations.
   • CEncryption will cause a significant performance degradation because all data must be encrypted in software.
   • DEncryption will have minimal performance impact because the encryption is handled by the drive hardware.

   Which characteristic is typical of encryption-capable drives used in E-Series systems?

   • AThey have a larger physical size than non-encrypted drives
   • BThey require a separate encryption appliance to function
   • CThey are only available in solid-state drives (SSDs), not in hard disk drives (HDDs)
