A.
four

six
C.
eight
D.
ten
Explanation:
You should use eight hard disk drive bays for each server. RAID 1 establishes disk mirroring by using two or more hard disks. This configuration produces slow write operations, but relatively quick read operations, and provides a means to maintain high data availability on servers, because a single disk can be lost without any loss of data. RAID 5 requires a minimum of three hard disks. RAID 5 uses disk striping with parity to provide fault tolerance. This indicates that a minimum of five hard disk drives will be required to configure RAID 1 for the operating system and RAID 5 for storing data. However, the recommended number of hard disk drive bays is eight for the Management Server and the Messaging Server. This provides in-server storage expansion by using dedicated hot swap drives.You should not use four, six, or ten hard disk drive bays for each server. The recommended number of hard disk drive bays for Management and Messaging servers is eight.
