Exam SK0-005 topic 1 question 94 discussion

Actual exam question from CompTIA's SK0-005

Question #: 94
Topic #: 1

A systems administrator needs to configure a new server and external storage for a new production application environment. Based on end-user specifications, the new solution needs to adhere to the following basic requirements:
1. The OS must be installed in a separate disk partition. In case of hard drive failure, it cannot be affected.
2. Application data IOPS performance is a must.
3. Data availability is a high priority, even in the case of multiple hard drive failures.
Which of the following are the BEST options to comply with the user requirements? (Choose three.)

A. Install the OS on a RAID 0 array.
B. Install the OS on a RAID 1 array.
C. Configure RAID 1 for the application data.
D. Configure RAID 5 for the application data.
E. Use SSD hard drives for the data application array.
F. Use SATA hard drives for the data application array.
G. Use a single JBOD for OS and application data.

This is an absurdly stupid question. I assume it is a typo and the RAID5 should actually be RAID6. RAID1 can only support multiple drive failures if it is more than 2 disks at which point it is RAID10.

Given the requirements, the best options to comply with the user's specifications are: B. Install the OS on a RAID 1 array. E. Use SSD hard drives for the data application array. Considering the need for high data availability and the risk of multiple drive failures, RAID 1 (mirroring) with more than two drives or RAID 10 (a combination of RAID 1 and RAID 0) would be more suitable than RAID 5. Since RAID 10 is not an option here and RAID 1 provides redundancy, C. Configure RAID 1 for the application data would be the third best choice.

1. The OS must be installed in a separate disk partition. In case of hard drive failure, it cannot be affected. = RAID 1 2. Application data IOPS performance is a must. = SSD 3. Data availability is a high priority, even in the case of multiple hard drive failures.= RAID 1, RAID 6 writes parity information across the drives as is done in RAID 5, but it writes two stripes, which allows the system to recover from two drive failures whereas RAID 5 cannot.
