CompTIA Server+ (SK0-005) — Question 55

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.)

Answer options

• 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.

Correct answer: B, C, E

Explanation

Installing the OS on a RAID 1 array (option B) protects it from hard drive failure, while configuring RAID 1 for application data (option C) ensures data redundancy and availability. Using SSD hard drives (option E) enhances IOPS performance, making it the best choice for application data. Options A, D, F, and G do not satisfy all the requirements, particularly regarding data availability and performance.
